1 00:00:00,680 --> 00:00:06,350 Hire everyone in this story we're going to go ahead and we're going to create a new activity called 2 00:00:06,440 --> 00:00:12,710 update martial arts activity in order to allow the users to update our specific martial art objects. 3 00:00:12,710 --> 00:00:15,810 That is safe to say to this database. 4 00:00:16,130 --> 00:00:19,950 So here open it up for them and then offered this job for that. 5 00:00:20,030 --> 00:00:23,330 And he opened this actually the first package. 6 00:00:23,360 --> 00:00:24,430 Right click on it. 7 00:00:24,500 --> 00:00:29,300 New activity empty activity. 8 00:00:29,480 --> 00:00:37,760 So the name of this activity is going to be up date martial arts activity. 9 00:00:37,900 --> 00:00:40,890 So here you can see that it's going to create a lay out for us. 10 00:00:40,900 --> 00:00:45,580 It's going to generate Ali outfight for us called Actually with the Underland update Underland Marshall 11 00:00:45,610 --> 00:00:46,670 Underland art. 12 00:00:46,990 --> 00:00:48,870 So it is not going to be a lot of activity. 13 00:00:48,880 --> 00:00:53,700 Backwards compatibility enabled the package and then click on finish. 14 00:00:54,100 --> 00:00:55,820 So let's wait a little bit here. 15 00:00:55,900 --> 00:01:00,560 So now that this activity is created this update activity is created. 16 00:01:00,570 --> 00:01:06,980 Again we are going to design the user interface programmatically because we do not know how many art 17 00:01:07,030 --> 00:01:09,110 optics are needed to be updated. 18 00:01:09,130 --> 00:01:13,570 OK we do not know how many Marshall objects are saved to escalate database. 19 00:01:13,840 --> 00:01:17,680 So we are going to design the user interface programmatically. 20 00:01:17,680 --> 00:01:23,020 So as you can see we have this update marshal activity less publicly tried to stop here in order to 21 00:01:23,020 --> 00:01:26,630 make this area a wider. 22 00:01:26,770 --> 00:01:31,700 So here first of all we need to have a reference to database handler. 23 00:01:31,750 --> 00:01:32,180 OK. 24 00:01:32,260 --> 00:01:34,820 So inside this class update Mosteller activity. 25 00:01:35,050 --> 00:01:41,500 I'm going to just type in a private database handler database handler semicolon. 26 00:01:41,650 --> 00:01:42,530 Let's go into this. 27 00:01:42,530 --> 00:01:48,460 Uncreate method and let's initialize this valuable database handler assignment operator new database 28 00:01:48,460 --> 00:01:51,990 handler and we are going to pass the context. 29 00:01:52,150 --> 00:01:58,140 So the context is going to be a great martial art activity that this right semicolon. 30 00:01:58,570 --> 00:02:05,320 And here we are going to actually call the modify user interface method here again and you're going 31 00:02:05,320 --> 00:02:06,720 to actually create it here. 32 00:02:06,730 --> 00:02:16,140 So modify user interface modify user interface and then put up at a fancy Pattis is your semicolon. 33 00:02:16,330 --> 00:02:21,670 So now let's go inside this class after the curly brace of this uncreate method and before the ending 34 00:02:21,700 --> 00:02:26,310 curly brace of this class we are going to create this method because we want to. 35 00:02:26,350 --> 00:02:29,130 These are designed to use an interface programmatically. 36 00:02:29,140 --> 00:02:30,580 So again private. 37 00:02:30,580 --> 00:02:37,200 So now let's specify the return type of the Smurfette which is void and the name of this method is modify 38 00:02:37,220 --> 00:02:42,580 the user interface and then put a pair of practice's here and then open and close the Smurfette by using 39 00:02:42,580 --> 00:02:45,250 these curly braces inside the Smurfit. 40 00:02:45,250 --> 00:02:52,000 Let's create an array list of martial art objects so that they can hear aerialist and instead the angle 41 00:02:52,000 --> 00:02:56,820 brackets we need to specify the type of the objects that we want to put inside this aerialist. 42 00:02:56,830 --> 00:03:05,760 So it is martial art and the name of this actually is going into martial art objects martial art objects 43 00:03:06,810 --> 00:03:08,350 assignment operator. 44 00:03:08,400 --> 00:03:14,130 So here we have an instance that is actually of type database handler right. 45 00:03:14,130 --> 00:03:21,900 We have a reference to the state of his handler instance so we can't say databus handler that return 46 00:03:22,380 --> 00:03:24,760 all martial art objects semicolon. 47 00:03:25,020 --> 00:03:26,740 And here I can say. 48 00:03:26,880 --> 00:03:30,720 So let me create a new line here so that you can see this line of code there. 49 00:03:30,840 --> 00:03:40,170 Now let's create an if statement so if Marshal or objects is actually that size if the number of elements 50 00:03:40,440 --> 00:03:46,950 that are inside of this at a radius actually is greater than zero and then I can open and close this 51 00:03:46,950 --> 00:03:49,290 if statement but using the curly braces. 52 00:03:49,290 --> 00:03:54,240 So here let's create a scroll view scroll view scroll view. 53 00:03:54,400 --> 00:04:00,640 Assignment operator new scroll view and inside Apprentice's meaning to press the context. 54 00:04:00,810 --> 00:04:06,530 So the context is update Marshlack activity that this update Marshlack activity. 55 00:04:06,600 --> 00:04:08,490 This semicolon. 56 00:04:08,670 --> 00:04:14,330 Now let's create a great layout so you are already familiar with discretely out in the app. 57 00:04:14,330 --> 00:04:22,250 Actually in the animal quiz app application I taught you how to use grittily out into the user interface. 58 00:04:22,500 --> 00:04:29,720 Actually by using the Examen quotes but here we want to create are greatly out by using Java codes programmatically 59 00:04:29,730 --> 00:04:30,410 right. 60 00:04:30,480 --> 00:04:33,750 So now let's specify the name of discretely out here. 61 00:04:33,780 --> 00:04:41,560 Assignment operator new grid layout and we need to pass again the context update motional activity that 62 00:04:41,620 --> 00:04:43,960 this semicolon. 63 00:04:44,280 --> 00:04:50,250 And here we need to specify the number of rows that we want to have inside our greedily. 64 00:04:50,280 --> 00:04:57,990 So just they've been here greatly out it that sets low count. 65 00:04:58,040 --> 00:05:04,680 So here for the count I can just refer to this Matia that objects that size. 66 00:05:04,890 --> 00:05:13,500 OK so the number of elements that are inside of these are a list of objects is going to specify the 67 00:05:13,520 --> 00:05:16,610 number of rows that we have inside are really out. 68 00:05:16,880 --> 00:05:17,360 OK. 69 00:05:17,600 --> 00:05:25,920 So now now actually we need to specify that number of columns that we want to have inside our great 70 00:05:26,000 --> 00:05:26,460 layout. 71 00:05:26,510 --> 00:05:33,960 So I can't say great lay out that sets column count OK here. 72 00:05:34,050 --> 00:05:34,880 The number of column. 73 00:05:34,980 --> 00:05:39,020 So the number of columns is going to be actually number 5. 74 00:05:39,330 --> 00:05:41,890 We want we need a column for the ID. 75 00:05:42,030 --> 00:05:43,810 The idea of the motion of the object. 76 00:05:43,830 --> 00:05:47,090 We need a column for the name of the martial art object. 77 00:05:47,130 --> 00:05:48,750 We need a column for that. 78 00:05:48,790 --> 00:05:56,080 Actually the price of that Marshall object and we need another color for the color of that monster object. 79 00:05:56,280 --> 00:06:04,860 And we also need actually another color for the button that is going to actually let the user to update 80 00:06:05,250 --> 00:06:08,500 or modify that specific martial art object right. 81 00:06:08,520 --> 00:06:12,240 So not just that this is our update martial art activity class. 82 00:06:12,240 --> 00:06:12,570 Right. 83 00:06:12,600 --> 00:06:21,500 So inside each row if you have to have five columns and are the name price color and there and a button 84 00:06:21,500 --> 00:06:28,030 for actually allowing the user to update or modify that specific motion or object. 85 00:06:28,110 --> 00:06:32,620 So that's why we want to have five columns inside our row. 86 00:06:32,640 --> 00:06:41,370 Now let's create an array of text views because we want to put our IDs inside a text view right so that 87 00:06:41,370 --> 00:06:45,860 history is going to be the representation of all of the ID of each motional object. 88 00:06:45,870 --> 00:06:52,650 So I see text view and then put a pair of brackets here in order to specify that this is going to be 89 00:06:52,650 --> 00:07:02,640 an array of takes views and the name of this part is going to be an ID text views ID text views assignment 90 00:07:02,640 --> 00:07:05,930 operator new text view. 91 00:07:06,450 --> 00:07:14,080 And then here inside the brackets I need to specify the size of this of this at a right. 92 00:07:14,110 --> 00:07:21,250 I need to specify that how many elements how many actually takes use that you want to have inside array. 93 00:07:21,490 --> 00:07:27,550 So if we want to have actually the number of elements of our emotional objects. 94 00:07:27,610 --> 00:07:36,310 OK so much for objects that size for each monster that object we need to have an ID right because each 95 00:07:36,310 --> 00:07:38,640 martial artist has a specific ID. 96 00:07:38,740 --> 00:07:46,390 So we might we want to have the size of this object to be the number of elements of this arey. 97 00:07:46,780 --> 00:07:49,570 So here after this line of code I can't say. 98 00:07:49,780 --> 00:07:53,740 So now we want to create a two dimensional array. 99 00:07:53,740 --> 00:07:57,700 Actually it is going to be an array of edit texts. 100 00:07:57,700 --> 00:07:59,360 So let's create that here. 101 00:07:59,480 --> 00:08:01,200 And it takes just typing here. 102 00:08:01,250 --> 00:08:06,600 It takes put a pair of brackets here and put another proft brackets here. 103 00:08:06,610 --> 00:08:11,970 It is going to be a two dimensional array and add a that actually contains abbes. 104 00:08:11,980 --> 00:08:15,780 So now let's specify the name of these two dimensional at 8. 105 00:08:15,850 --> 00:08:26,360 It is going to be EDT name's prices colors names places and colors. 106 00:08:26,480 --> 00:08:28,050 It's more meaningful in this way. 107 00:08:28,070 --> 00:08:30,120 Assignment operator. 108 00:08:30,480 --> 00:08:35,910 So now we need to say new edit text this is going to be a two dimensional array right. 109 00:08:36,080 --> 00:08:39,820 So we need to specify the size of the first at a. 110 00:08:39,910 --> 00:08:40,180 OK. 111 00:08:40,180 --> 00:08:44,800 The size of the elements that you want to put in in there first. 112 00:08:45,020 --> 00:08:52,830 So the size is going to be again Marshall objects that size right now for the second actually. 113 00:08:53,000 --> 00:08:55,210 Are they here for this one. 114 00:08:55,220 --> 00:08:57,650 This is this is going to be at a site. 115 00:08:57,680 --> 00:08:59,830 This big area inside is one. 116 00:09:00,140 --> 00:09:05,960 So here for this one that we need to specify the exact number of elements it is going to be free. 117 00:09:05,960 --> 00:09:09,470 Notice that we have names Price's colors. 118 00:09:09,650 --> 00:09:16,520 So it actually takes for the name we need and it takes for the price and we need another and it takes 119 00:09:16,520 --> 00:09:17,400 for the colors. 120 00:09:17,450 --> 00:09:17,990 Right. 121 00:09:18,020 --> 00:09:20,340 So at the end of your statement just put a semicolon here. 122 00:09:20,360 --> 00:09:25,310 Let me create a new line here so that you can see this line of code better. 123 00:09:25,670 --> 00:09:34,040 Now after this line of code I can't say so remember here I told you that in each row you must have a 124 00:09:34,040 --> 00:09:40,000 button in order to allow the user to modify or update that specific martial art object. 125 00:09:40,010 --> 00:09:42,870 So we need to also have an array of buttons. 126 00:09:42,890 --> 00:09:48,350 So after this line of code I can see a button I put a pair of brackets in order to specify that this 127 00:09:48,350 --> 00:09:56,060 is going to be an array of buttons and the name of this variable is going to be modified partons modify 128 00:09:56,810 --> 00:10:05,110 buttons assignment operator right new button. 129 00:10:05,800 --> 00:10:06,280 OK. 130 00:10:06,430 --> 00:10:12,100 And inside the brackets meaning to specify the size all you need to specify the number of elements that 131 00:10:12,100 --> 00:10:13,540 this area is going to hold. 132 00:10:13,630 --> 00:10:19,930 So again it is going to be modular objects that size for each Marshall object if you want to have a 133 00:10:19,930 --> 00:10:24,500 modified button an update button right after this and of course I can't say. 134 00:10:24,760 --> 00:10:30,930 So we need to also be notified that vendor use that actually to interacts with these modify buttons. 135 00:10:30,990 --> 00:10:34,170 If you want to be notified right this class should be notified. 136 00:10:34,390 --> 00:10:40,570 So in order to do that first this update module activity class must implement the view that Uncle Clisson 137 00:10:40,580 --> 00:10:41,230 or interface. 138 00:10:41,230 --> 00:10:47,070 So just scroll to the top here it says update motional activity X pens app compact activity. 139 00:10:47,110 --> 00:10:55,850 And then here just typing implements view that unclick listener because the school has now implements 140 00:10:56,300 --> 00:10:57,160 this interface. 141 00:10:57,230 --> 00:11:03,020 We must actually implement or we must provide an implementation for the method that we have in say the 142 00:11:03,020 --> 00:11:09,620 view that we consumer interface just scroll down here and before the end in calibrates of this class 143 00:11:09,620 --> 00:11:12,720 marshal activity just like in here unclick. 144 00:11:13,180 --> 00:11:14,300 That's it. 145 00:11:14,460 --> 00:11:14,720 Right. 146 00:11:14,720 --> 00:11:20,420 So we have this unclick my faith and this method is going to be executed whenever the user interacts 147 00:11:20,480 --> 00:11:22,030 with that modified button. 148 00:11:22,370 --> 00:11:22,820 OK. 149 00:11:23,000 --> 00:11:27,410 So if we also have this argument which is going which is the user interface component or that specific 150 00:11:27,410 --> 00:11:30,440 button that is clicked or touched. 151 00:11:30,530 --> 00:11:32,390 So let's go up here. 152 00:11:32,930 --> 00:11:38,720 Now after descent of what inside this method right inside this modify user interface method after creating 153 00:11:38,720 --> 00:11:42,830 this idea is this idea of buttons here I can't say. 154 00:11:42,920 --> 00:11:51,800 So here we want to actually access the width of the screen of the user's device right. 155 00:11:51,920 --> 00:11:55,040 So in order to do that you need to create a variable of type point. 156 00:11:55,160 --> 00:12:03,630 So I can say point the name of this variable is going to be screen size screen size assignment operator 157 00:12:04,080 --> 00:12:08,240 new point by semicolon. 158 00:12:08,330 --> 00:12:09,910 Now they've been here. 159 00:12:09,920 --> 00:12:19,640 Get window manager that get default display that get size and now you need to pass an argument to this 160 00:12:19,670 --> 00:12:20,430 get seismic. 161 00:12:20,450 --> 00:12:26,640 So that is going to assign the size of the screen to this screen size body of it. 162 00:12:26,690 --> 00:12:30,930 So I'm going to actually pass this screen size to this effect. 163 00:12:31,010 --> 00:12:38,540 And now this screen size variable holds there actually the size of the screen of the user's device. 164 00:12:38,560 --> 00:12:44,080 So in this way I can actually access the width of this screen but let's create a value of that integer 165 00:12:44,230 --> 00:12:52,690 int and then of this by the body's screen with assignment operator and I can refer to this screen size 166 00:12:52,690 --> 00:12:56,940 variable which is a point that X semicolon. 167 00:12:57,100 --> 00:13:01,050 Now this variable holds the width of this screen. 168 00:13:01,090 --> 00:13:08,900 Let's create a counter variable so in counter as I mean operator zero semicolon. 169 00:13:09,260 --> 00:13:12,030 Now let's create a for loop for. 170 00:13:12,560 --> 00:13:19,200 Now I want to iterate over each marshal or object that we have inside this at least right marginal objects. 171 00:13:19,220 --> 00:13:27,900 So I can say actually martial arts martial art object martial arts object. 172 00:13:28,040 --> 00:13:32,180 So this is actually a valuable right now here I need to put a call in here. 173 00:13:32,330 --> 00:13:35,290 And then after this call I can refer to this at a. 174 00:13:35,300 --> 00:13:36,730 Martial art objects. 175 00:13:36,860 --> 00:13:43,590 So you know that this fall in love here is going to actually execute for each martial artist. 176 00:13:43,610 --> 00:13:48,310 This fall is going to be executed for each motion of objects that we have inside this at least. 177 00:13:48,380 --> 00:13:49,010 Right. 178 00:13:49,370 --> 00:13:55,030 So inside this for loop we want to populate the areas that we created here. 179 00:13:55,030 --> 00:13:56,840 Look at these areas here. 180 00:13:56,900 --> 00:14:02,140 So for example in number 47 We created an array of type text view here. 181 00:14:02,180 --> 00:14:08,540 It takes views and they said that the number of elements that this area can accept is actually the size 182 00:14:08,720 --> 00:14:10,390 of the multiple objects frailest. 183 00:14:10,420 --> 00:14:10,830 Right. 184 00:14:10,880 --> 00:14:12,630 Give me a specified this are here. 185 00:14:12,740 --> 00:14:16,670 But we did not populated populate this area yet. 186 00:14:16,880 --> 00:14:23,240 So it is for a loop here because this is going to be executed for each Monserrat object that we have 187 00:14:23,240 --> 00:14:24,900 inside these multiple objects array. 188 00:14:24,960 --> 00:14:32,770 And it is actually we want to create a text view for the ID of each monstrous object. 189 00:14:32,780 --> 00:14:35,010 So let's refer to this right here. 190 00:14:35,020 --> 00:14:39,490 All it takes to use and let's put a pair of brackets here. 191 00:14:39,510 --> 00:14:46,350 So I want to go inside the index zero of this array and I want to assign a value or text view to the 192 00:14:46,350 --> 00:14:48,070 index zero of this. 193 00:14:48,300 --> 00:14:49,830 So index 0. 194 00:14:49,860 --> 00:14:53,870 So why should I actually put index 0 here. 195 00:14:53,970 --> 00:14:58,920 We actually created a variable of type counter here. 196 00:14:58,980 --> 00:15:04,560 So in this way because this for loop this folly in loop here is going to be executed for each Montral 197 00:15:04,560 --> 00:15:11,970 object that we have inside this at least in this way we can populate or Aurelia's or takes you actually 198 00:15:11,970 --> 00:15:13,240 the artist view a. 199 00:15:13,710 --> 00:15:18,220 And if we can put a text view for each Marshall object. 200 00:15:18,250 --> 00:15:22,890 So instead of passing the value 0 that's passed the value counter here. 201 00:15:23,140 --> 00:15:23,730 Right. 202 00:15:23,770 --> 00:15:32,200 And because this counter here should be must be actually incremented after executing after each execution 203 00:15:32,200 --> 00:15:33,340 of this for loop here. 204 00:15:33,430 --> 00:15:35,820 Let's put it here so that we don't forget it. 205 00:15:35,950 --> 00:15:41,140 So just at the design of coaches they can here a counter plus plus a. 206 00:15:41,380 --> 00:15:43,010 Right now. 207 00:15:43,170 --> 00:15:49,370 So for the first time that this will appear is going to be executed the first object that we have inside 208 00:15:49,370 --> 00:15:49,830 is at. 209 00:15:49,860 --> 00:15:50,170 Right. 210 00:15:50,180 --> 00:15:51,360 This is our latest. 211 00:15:51,460 --> 00:15:55,160 So now we have this counter the counter is now zero. 212 00:15:55,360 --> 00:15:56,180 Right. 213 00:15:56,200 --> 00:16:00,280 So if we passed it the counter here which means index number 0. 214 00:16:00,340 --> 00:16:07,940 I want to pass over to assign a text view to the index number zero of this it takes views. 215 00:16:08,230 --> 00:16:13,860 So assignment operator Miyu takes you right. 216 00:16:13,870 --> 00:16:20,830 So here I just need to pass the context which is this one update multiple activity to this semicolon. 217 00:16:20,950 --> 00:16:23,460 Let me tell you a very important point. 218 00:16:23,470 --> 00:16:25,780 This is very important Pay attention here. 219 00:16:25,830 --> 00:16:27,480 Look at this great out here. 220 00:16:27,490 --> 00:16:29,390 We have a gradely right. 221 00:16:29,500 --> 00:16:36,490 And we are going to put our great grittily out inside this scroll you village that we haven't still 222 00:16:36,580 --> 00:16:41,070 put the codes in order to actually put the crudely out inside this scroll. 223 00:16:41,080 --> 00:16:47,260 But for now just know that we are going to do that later and notice that we have here this line of code 224 00:16:47,260 --> 00:16:48,220 in line number 44. 225 00:16:48,220 --> 00:16:56,200 I said that you are going to have the size of a Marshall object that is going to be the number of elements 226 00:16:56,200 --> 00:17:01,600 or the number of rows that we have inside discretely out and inside each you know we are going to have 227 00:17:01,600 --> 00:17:03,250 five columns. 228 00:17:03,250 --> 00:17:07,870 The first column is going to be for the ID of that Monserrat object. 229 00:17:07,870 --> 00:17:08,750 Right. 230 00:17:08,890 --> 00:17:15,820 So this means that here when I actually create a new text view and I put it inside the index number 231 00:17:15,820 --> 00:17:26,420 zero of this ID takes viewers at a later event when I want to actually put this text view inside are 232 00:17:26,930 --> 00:17:34,460 greatly out this text is going to be inside the index number one actually is that column number 1 in 233 00:17:34,610 --> 00:17:38,500 so the column number one of this Goodley are automatically OK. 234 00:17:38,570 --> 00:17:42,730 This process is going to be executed automatically. 235 00:17:42,800 --> 00:17:45,000 So after this thing of course of not just don't vote. 236 00:17:45,040 --> 00:17:52,010 If it's actually a little bit complex don't worry I'm going to explain it more in a later here. 237 00:17:52,080 --> 00:17:54,390 Don't worry just like these courts here. 238 00:17:54,620 --> 00:17:59,310 But if you have any questions you can post the discussion in the course or you can message me in with 239 00:17:59,350 --> 00:18:02,110 me and then I do my best to answer all of your questions. 240 00:18:02,120 --> 00:18:09,360 So here we created a text view and we assign it to the index counter of this idea takes use. 241 00:18:09,410 --> 00:18:15,110 So here instead of saying that the name of this variable is counted let's change it to index its more 242 00:18:15,110 --> 00:18:16,570 meaningful index. 243 00:18:16,880 --> 00:18:20,060 Let's also change this counter to index. 244 00:18:20,260 --> 00:18:24,720 And here let's say index plus plus index plus plus. 245 00:18:24,730 --> 00:18:26,310 So that's it. 246 00:18:26,320 --> 00:18:36,300 Now I can say so let me tell you that each text view has a gravity attribute which is going to specify 247 00:18:36,690 --> 00:18:42,000 the position of the text of that takes you inside the parent. 248 00:18:42,000 --> 00:18:44,520 So we have a text view which is the parent. 249 00:18:44,640 --> 00:18:45,200 Right. 250 00:18:45,360 --> 00:18:50,590 And we have a text inside that takes a view which is going to be the child of that takes you right. 251 00:18:50,610 --> 00:18:57,410 So I want to center the text of that text view on the center at the center of the text view OK. 252 00:18:57,600 --> 00:19:02,740 So I can say Id takes views and I put a pair of brackets here. 253 00:19:02,800 --> 00:19:09,660 Index that set gravity write that says gravity. 254 00:19:09,660 --> 00:19:16,100 And then I can say gravity with capital G that center. 255 00:19:16,290 --> 00:19:17,450 That's it. 256 00:19:17,440 --> 00:19:23,690 I want to center the text of that takes you inside that takes you right the habit takes you the parent. 257 00:19:23,700 --> 00:19:26,700 We have the text insert atus view which is the choice. 258 00:19:26,790 --> 00:19:33,930 So you want to position the child in the center at the at the center of the takes of you so that's it 259 00:19:34,080 --> 00:19:35,310 gravity that's it. 260 00:19:35,620 --> 00:19:40,810 So now it's time to specify the text of that takes you right. 261 00:19:40,870 --> 00:19:50,270 I can see why it takes views and then they just put a pair of brackets index that said text so the text 262 00:19:50,360 --> 00:19:53,600 is going to be martial art object. 263 00:19:53,600 --> 00:19:56,300 So we have this martial object valuable right. 264 00:19:56,450 --> 00:19:58,500 That gets a D gets. 265 00:19:58,510 --> 00:20:05,940 Marshall ID and because this is of type integer they get Marshall the idea if it is going to return 266 00:20:06,320 --> 00:20:12,740 a value of an integer and this takes and if it needs a value of type String we must convert this value 267 00:20:12,740 --> 00:20:13,860 twice think value. 268 00:20:13,860 --> 00:20:18,330 So here we just need to put up the contamination OPERATOR Two coats. 269 00:20:18,450 --> 00:20:18,810 OK. 270 00:20:18,970 --> 00:20:22,370 Marshall object that did that Id plus two calls. 271 00:20:22,380 --> 00:20:24,140 So now it is converted to a string value. 272 00:20:24,160 --> 00:20:31,240 And now we can assign it this value to the text actually a property of this ID takes you index. 273 00:20:31,320 --> 00:20:41,130 So now after this line of code we need to specify actually the text actually the text that we have that 274 00:20:41,130 --> 00:20:43,740 you are going to have inside this edit takes great. 275 00:20:43,780 --> 00:20:45,340 This is going to be a two dimensional array. 276 00:20:45,360 --> 00:20:45,910 Right. 277 00:20:46,230 --> 00:20:52,230 So we need to create an edit text for the name of the monster that we need to create another edit text 278 00:20:52,230 --> 00:20:54,970 for the price of that market. 279 00:20:55,170 --> 00:20:59,580 And we need to create another taste for the color of that martial art. 280 00:20:59,610 --> 00:21:03,750 So here you can see these two dimensional art. 281 00:21:03,780 --> 00:21:04,840 Right. 282 00:21:04,950 --> 00:21:06,640 I can refer to that dimension or a. 283 00:21:06,640 --> 00:21:07,310 Here it is. 284 00:21:07,320 --> 00:21:12,560 He names places and colors and he just put a pair of brackets. 285 00:21:12,570 --> 00:21:14,720 So this is going to be the first arii. 286 00:21:14,730 --> 00:21:15,360 Right. 287 00:21:15,660 --> 00:21:17,510 So now we have this index here. 288 00:21:17,520 --> 00:21:26,240 So if you want to go to actually index number to zero so just put poost put a value index here because 289 00:21:26,810 --> 00:21:27,860 this is the first time. 290 00:21:27,860 --> 00:21:31,720 For example assume that this is the first time that this for loop is going to be executed. 291 00:21:31,850 --> 00:21:36,690 So we just passed the value index here and now currently the value of the index is zero right. 292 00:21:36,710 --> 00:21:38,640 So I just passed the index here. 293 00:21:38,880 --> 00:21:41,390 So vatos index mean he here this index. 294 00:21:41,390 --> 00:21:44,850 So I told you we have an array of arrays. 295 00:21:45,230 --> 00:21:45,740 Right. 296 00:21:45,740 --> 00:21:50,780 So its going to go inside the first Aure inside this area here. 297 00:21:51,140 --> 00:21:56,590 Index and we are going to actually go ahead and we are going to just put a pair of brackets here. 298 00:21:56,870 --> 00:21:58,800 And we are going to specify. 299 00:21:59,210 --> 00:22:05,790 So I told you that we have three actually which are three elements in each array here. 300 00:22:05,960 --> 00:22:06,440 Right. 301 00:22:06,440 --> 00:22:07,730 So this is the first array. 302 00:22:07,910 --> 00:22:11,610 And inside that first array we are going to have three elements. 303 00:22:11,690 --> 00:22:18,220 So the first element is going to be 0 right which is going to specify the name actually the name ID 304 00:22:18,230 --> 00:22:21,140 text for their Monserrat object. 305 00:22:21,740 --> 00:22:23,940 And I put an assignment operator here. 306 00:22:24,070 --> 00:22:33,190 Now you edit text and I just adjacent to pass the context update marshal activity that this. 307 00:22:33,530 --> 00:22:36,110 So here lets put a semicolon at the end of our statement. 308 00:22:36,110 --> 00:22:45,410 Let me show you that here we created an edited X for the first A-Day and inserted a for the first element 309 00:22:45,980 --> 00:22:46,950 right. 310 00:22:47,030 --> 00:22:52,570 We created it we created an edit text for that here which is going to be for the name. 311 00:22:52,570 --> 00:22:57,850 And that's why the name of this valuable is names prices and colors. 312 00:22:57,950 --> 00:23:00,040 The name is going to be the first element. 313 00:23:00,050 --> 00:23:05,390 Inside each aere the price is going to be the second element inside each area and the color is going 314 00:23:05,390 --> 00:23:07,570 to be the first element inside the static. 315 00:23:07,850 --> 00:23:10,430 So that's why I passed the index 0. 316 00:23:10,460 --> 00:23:15,420 So I'll tell you that in programming we always count from number zero. 317 00:23:15,470 --> 00:23:25,880 So after this line of code I can't say EDT names prices and coloreds just put a pair of brackets here. 318 00:23:25,880 --> 00:23:29,030 So again pass the value index here. 319 00:23:29,040 --> 00:23:30,390 Still we are inside. 320 00:23:30,530 --> 00:23:36,350 Actually the first R8 is that the index number zero of that beach area which is going to be the first 321 00:23:36,350 --> 00:23:37,540 that is right. 322 00:23:37,550 --> 00:23:43,250 So now if you want to actually create another it it takes for the second element of that a which is 323 00:23:43,250 --> 00:23:45,260 going to be the price. 324 00:23:45,260 --> 00:23:48,630 So just put another of brackets and put number one here. 325 00:23:48,870 --> 00:23:49,400 Right. 326 00:23:49,460 --> 00:23:52,890 Assignment operator again new text. 327 00:23:53,030 --> 00:23:54,410 Hopefully that makes sense. 328 00:23:54,410 --> 00:23:57,830 It can be a little complex to actually figure out what's going on here. 329 00:23:58,040 --> 00:23:59,690 But don't worry about it. 330 00:24:00,080 --> 00:24:02,440 I'm going to explain it again here. 331 00:24:02,490 --> 00:24:04,590 Just write these lines of code here. 332 00:24:04,670 --> 00:24:09,800 And if you have actually problems always you can always opposed the discussion in the course and then 333 00:24:09,830 --> 00:24:11,500 I do my best to answer all of your questions. 334 00:24:11,510 --> 00:24:12,590 So what it takes. 335 00:24:12,590 --> 00:24:20,660 And I just need to pass the context update martial activity that this that this semicolon. 336 00:24:20,700 --> 00:24:23,070 So here we have a typo here. 337 00:24:23,310 --> 00:24:24,440 So now the error is caught. 338 00:24:24,480 --> 00:24:25,000 OK. 339 00:24:25,140 --> 00:24:29,970 And now we need to actually create another text for the word color. 340 00:24:30,150 --> 00:24:30,570 Right. 341 00:24:30,720 --> 00:24:38,710 So after this line of code I can't say the names and prices and colors and just put up have brackets. 342 00:24:38,730 --> 00:24:46,210 So again index and then I put a pair of brackets again and here index number two. 343 00:24:46,650 --> 00:24:47,220 OK. 344 00:24:47,220 --> 00:24:50,710 Assignment operator again new edit text. 345 00:24:50,730 --> 00:24:59,860 So I just need to pass this context update marshal activity to this semicolon So now we created actually 346 00:24:59,860 --> 00:25:07,990 free edit texts for each grade that we have inside these editing names and prices are edited edited 347 00:25:07,990 --> 00:25:09,620 names prices and colors. 348 00:25:09,760 --> 00:25:10,210 Right. 349 00:25:10,450 --> 00:25:15,030 So we have actually a beach area that holds other areas. 350 00:25:15,250 --> 00:25:23,240 So inside each tree that we have inside that area inside each R8 we are going to have three texts OK. 351 00:25:23,320 --> 00:25:26,030 The first one is for the name. 352 00:25:26,080 --> 00:25:29,350 The second is going to be for the price. 353 00:25:29,350 --> 00:25:34,830 And the first editor he's going to be for the color of that martial art object. 354 00:25:34,840 --> 00:25:43,000 So here it's time to specify the text of each edit text that we have inside these two dimensional array. 355 00:25:43,120 --> 00:25:51,190 So again let me create a new line here and here I can say edit the names prices and colors and put a 356 00:25:51,180 --> 00:25:52,900 pair of Ratchet's again index. 357 00:25:53,120 --> 00:25:59,660 And here again put another prop brackets index number 0 because I want to specify the name right dot 358 00:26:00,020 --> 00:26:02,940 set text. 359 00:26:02,970 --> 00:26:05,500 So here I just need to pass the text. 360 00:26:05,520 --> 00:26:14,130 So what is the text the text is going to be martial art object that gets martial art name. 361 00:26:14,700 --> 00:26:15,670 That's it. 362 00:26:16,140 --> 00:26:20,190 So we are inside that Arey editing names prices and colors. 363 00:26:20,190 --> 00:26:23,390 This is a two dimensional array an array that holds other arrows. 364 00:26:23,570 --> 00:26:27,430 You are going to go inside the index 0 of that array. 365 00:26:27,540 --> 00:26:30,210 So it is going to be an add another array right. 366 00:26:30,210 --> 00:26:34,920 And if you are going to go inside that array and if you are going to go inside the index number zero 367 00:26:34,920 --> 00:26:40,100 of that Arey index number zero that rabbit is going to be for the name Marshall name. 368 00:26:40,440 --> 00:26:44,720 And we say that said text is actually text right. 369 00:26:44,840 --> 00:26:52,040 That's a text Marshall object that get Marshall that name again the same scenario for the price of that 370 00:26:52,050 --> 00:26:52,990 Marshall update. 371 00:26:53,000 --> 00:26:58,980 So it is names prices and color is again put a pair of brackets index. 372 00:26:59,060 --> 00:27:10,200 This time we are going to insert an index number one that set text Marshall object dot and this time 373 00:27:10,250 --> 00:27:15,570 I want to get the Marshall dot price right get martial art price. 374 00:27:15,580 --> 00:27:21,740 So because this is going to be of type double here you need to convert this value to our string value 375 00:27:21,740 --> 00:27:26,690 so I can just put a concatenation operator and two cards right. 376 00:27:26,800 --> 00:27:33,920 And because inside that it the user is supposed to only enter a number not a text. 377 00:27:34,040 --> 00:27:40,840 You can specify the input type of that text so I can just say it it names prices and colors and put 378 00:27:40,840 --> 00:27:43,720 a pair of brackets your index again. 379 00:27:43,750 --> 00:27:49,770 Index Number 1 dot set input type that set in pooch's type 380 00:27:52,520 --> 00:27:54,980 inside the apprentice is it's just a pinhead input type 381 00:27:58,180 --> 00:27:58,650 number. 382 00:27:58,690 --> 00:27:59,530 That's just typing here. 383 00:27:59,530 --> 00:28:08,800 Number type class number so in this way the user can only enter a number inside this edit text because 384 00:28:08,800 --> 00:28:12,400 this is going to be the price of the martial art object. 385 00:28:12,400 --> 00:28:22,210 After this line of code here we need to specify actually the text of the for the color or text for it 386 00:28:22,220 --> 00:28:25,300 it takes which is for the color of that art object. 387 00:28:25,330 --> 00:28:30,000 So it names places and colors index. 388 00:28:30,280 --> 00:28:36,780 Just put the value index inside the first pair of brackets and again put on another pair of brackets. 389 00:28:36,790 --> 00:28:42,970 And this time we are going to insert the index number two of that at a time and up and just type it 390 00:28:42,970 --> 00:28:43,510 here. 391 00:28:43,570 --> 00:28:45,440 That said text. 392 00:28:45,670 --> 00:28:51,770 And he'll just refer to this martial art object that get martial art color. 393 00:28:51,930 --> 00:28:52,240 Right. 394 00:28:52,240 --> 00:29:00,670 That's it's not at the specified the text of each edit text that we have inside our two dimensional 395 00:29:00,730 --> 00:29:01,570 array. 396 00:29:01,690 --> 00:29:08,570 We need to specify an ID for each edit text that we're going to have inside these two dimensional array. 397 00:29:08,770 --> 00:29:09,610 OK. 398 00:29:09,610 --> 00:29:12,830 Because later we need to use this ID. 399 00:29:13,030 --> 00:29:14,420 OK this is very important. 400 00:29:14,490 --> 00:29:16,900 This must be this ID must be a unique ID. 401 00:29:16,900 --> 00:29:22,250 So let me show you how you can create a unique ID for each ID text. 402 00:29:22,390 --> 00:29:30,020 So here I can actually create a new line here so I can say edit the names prices and colors right. 403 00:29:30,090 --> 00:29:35,130 I put a pair of brackets index and again where is the index number 0. 404 00:29:35,140 --> 00:29:41,830 Because I want to specify the ID for the index for the editor that is instead of index number zero of 405 00:29:41,840 --> 00:29:43,560 these two dimensional r.e. 406 00:29:43,690 --> 00:29:44,380 Right. 407 00:29:44,450 --> 00:29:46,640 What sets ID. 408 00:29:47,510 --> 00:29:56,190 So the ID is going to be marshal or object that gets Id get ID plus 10 right. 409 00:29:56,200 --> 00:29:57,750 This is going to be a unique ID. 410 00:29:57,750 --> 00:30:04,020 I am referring to and getting the ID of that object and I am adding the value 10 to that value. 411 00:30:04,180 --> 00:30:09,820 So this is going to be the ID of this ID text which is for that name ID text right after this line of 412 00:30:09,820 --> 00:30:10,340 code. 413 00:30:10,580 --> 00:30:17,340 I'm going to specify an ID for the price of that monster not so it the names prices and colors put up 414 00:30:17,340 --> 00:30:20,000 that approach its index. 415 00:30:20,440 --> 00:30:25,660 And now we are going to go into the index number one way to get the value that the editor that is inside 416 00:30:25,660 --> 00:30:27,130 the index number one of this area. 417 00:30:27,370 --> 00:30:36,320 That said Id again marshal or object that gets martial art ID. 418 00:30:36,320 --> 00:30:41,580 This time we are going to add the value number 20 to this value which is going to be a unique ID. 419 00:30:41,600 --> 00:30:42,220 Right. 420 00:30:42,320 --> 00:30:48,860 We are not going to use the same idea here because each marshal of each text must have a unique ID. 421 00:30:48,870 --> 00:30:49,960 This is very important. 422 00:30:49,970 --> 00:30:53,340 So thats why I added the value 20 to this ID. 423 00:30:53,780 --> 00:31:00,590 And again even to specify an ID for the color edit text so it is in names and names places and colors 424 00:31:00,980 --> 00:31:04,080 put a pair of brackets index. 425 00:31:04,200 --> 00:31:14,670 And here I passed the value number to that set id martial art object that get martial art ID at this 426 00:31:14,670 --> 00:31:18,570 time V.A to the value of fretty to this idea here. 427 00:31:18,570 --> 00:31:23,140 So it is going to generate a unique ID for the for the color of the text. 428 00:31:23,190 --> 00:31:29,490 So now that we created this edit text for are actually greatly We are going to put these added text 429 00:31:29,520 --> 00:31:35,630 inside the columns that we are going to have inside the rows of our greedily. 430 00:31:35,670 --> 00:31:40,950 So we created edit text free edit takes actually for the name price color you specify the text of each 431 00:31:41,010 --> 00:31:42,030 edit text here. 432 00:31:42,210 --> 00:31:44,970 And then we specified the idea of each eritis year. 433 00:31:44,970 --> 00:31:49,430 Now its time to work on the button that youre going to have inside each row. 434 00:31:49,550 --> 00:31:55,770 Right so now so a lot is that we are going to have an ID which is going to be inside the first column 435 00:31:55,770 --> 00:31:59,620 of our row and then we have these two dimensional array. 436 00:31:59,670 --> 00:32:01,680 So which is going to have a free editor. 437 00:32:01,710 --> 00:32:08,040 So the first one here the name is going to be in in the column the second column the price you're in 438 00:32:08,060 --> 00:32:14,530 is going to be in the first column and the color here is going to be in the fourth column right. 439 00:32:14,880 --> 00:32:20,610 And finally we are going to create a pattern that is that is going to be actually in the final column 440 00:32:20,670 --> 00:32:21,980 of our row right. 441 00:32:22,020 --> 00:32:25,870 So thats why we created 5 columns inside each row. 442 00:32:26,760 --> 00:32:32,180 So here after these lines of code I can say modified but hands free. 443 00:32:32,310 --> 00:32:40,800 I am referring to this modified pitance Arey right I put a bit of righteous index which is currently 444 00:32:40,800 --> 00:32:42,910 is actually 0 for example right. 445 00:32:42,930 --> 00:32:53,010 So instead of index 0 of this array we are going to create a new pattern so new pattern and that we 446 00:32:53,010 --> 00:32:58,500 need to pass the context of that martial art activity toward this that's a semicolon. 447 00:32:58,560 --> 00:33:06,240 So for the index 0 of these modified buttons are they are going to have a new bottom and I can't say 448 00:33:07,660 --> 00:33:15,790 so here it's time to specify the text of these buttons so modify the buttons again put a pair of brackets 449 00:33:15,850 --> 00:33:19,910 index Dot said text. 450 00:33:19,910 --> 00:33:22,990 The text is going to be just put two coats here. 451 00:33:22,990 --> 00:33:27,820 Modify and then after this line of code here. 452 00:33:28,140 --> 00:33:31,080 So it's time to specify the ID of this button. 453 00:33:31,080 --> 00:33:38,460 So modify buttons Zendiks that said ID. 454 00:33:38,460 --> 00:33:46,080 So the idea can be marshal object that gets marshal ID here this get module it is going to actually 455 00:33:46,080 --> 00:33:49,620 refer to the ID of that module object and it is going to be a unique ID. 456 00:33:49,620 --> 00:33:53,620 Here we did not use this ID anywhere else inside our codes. 457 00:33:53,790 --> 00:33:59,140 For example for the ID of these editors here you can see that. 458 00:33:59,270 --> 00:34:04,380 Actually created a unique ID for each ID text but here for that. 459 00:34:04,380 --> 00:34:08,850 But in here for that button that you are going to have for each martial art object in order to allow 460 00:34:08,850 --> 00:34:16,770 the user to modify or update that Marshall object their unique ID can be at Marshall ID the ID of each 461 00:34:16,770 --> 00:34:17,800 martial art. 462 00:34:18,030 --> 00:34:26,580 And then at the after design of code I need to say that each BOTTEN each modified button is going to 463 00:34:26,580 --> 00:34:28,050 have a listener. 464 00:34:28,050 --> 00:34:28,320 Right. 465 00:34:28,320 --> 00:34:34,050 So thats why we said that the update marshal that active declasse is actually implementing the view 466 00:34:34,050 --> 00:34:40,350 that Uncle listen or that means that this class is going to listen to the interactions of the user with 467 00:34:40,350 --> 00:34:41,250 the button. 468 00:34:41,430 --> 00:34:49,500 So I can say modified buttons and I put a pair of brackets index and I can see a set of click listener. 469 00:34:49,500 --> 00:34:55,090 So the president is going to be what update marshal activity to this. 470 00:34:55,170 --> 00:35:00,510 So this class is going to listen to the clicks of the user of it that should be on the button on the 471 00:35:00,840 --> 00:35:03,560 modified buttons index of each button. 472 00:35:03,570 --> 00:35:08,140 So thats why here if you scroll down here you can see that we implemented this method here unclick. 473 00:35:08,400 --> 00:35:09,680 So let's scroll to the top. 474 00:35:09,820 --> 00:35:15,960 And now here inside this update using interface Meffert here and the inside is a modified user interface 475 00:35:15,980 --> 00:35:17,840 Meffert after this line of code. 476 00:35:18,000 --> 00:35:22,200 I can say now it's time to add these components. 477 00:35:22,200 --> 00:35:25,440 For example Thisted this takes view this as it takes. 478 00:35:25,620 --> 00:35:29,490 And finally the Spartan two are greatly out. 479 00:35:29,490 --> 00:35:34,520 So I notice that all Gridley's is going to have rows and columns inside each row. 480 00:35:34,530 --> 00:35:35,860 You're going to have columns. 481 00:35:36,060 --> 00:35:42,750 So now I can't say great lay out thought at VU. 482 00:35:42,940 --> 00:35:45,550 So not just that we're going to pass the child here. 483 00:35:45,550 --> 00:35:45,980 Right. 484 00:35:46,120 --> 00:35:50,670 So we do have different versions of this Smif at the first one only accepts the child. 485 00:35:50,740 --> 00:35:53,760 The second version accepts the child and the index. 486 00:35:53,880 --> 00:35:58,930 There's a further version here access the child and the width and the height of that child you are going 487 00:35:58,930 --> 00:36:00,410 to have to lay out a part. 488 00:36:00,610 --> 00:36:05,590 And if you have the index and the layout perhaps here for our application we are going to use the first 489 00:36:05,590 --> 00:36:11,200 version of the Smurfette which is going to be the child width and height so the child is going to be 490 00:36:11,320 --> 00:36:12,620 actually there. 491 00:36:12,760 --> 00:36:14,080 It takes a view for the ID. 492 00:36:14,290 --> 00:36:22,670 So I can't say the takes views index right come up. 493 00:36:22,790 --> 00:36:26,340 So now I need to specify the width of the space for. 494 00:36:26,460 --> 00:36:33,650 So there is going to be actually the I'm going to eyeball this text view I want this year which is going 495 00:36:33,650 --> 00:36:37,710 to be for the ID to take only 8 percent of the vote of the screen. 496 00:36:37,850 --> 00:36:44,150 So that's why we actually created a variable here in order to get their video of the screen here right 497 00:36:44,150 --> 00:36:45,750 in line number 57. 498 00:36:45,770 --> 00:36:52,590 So now with so here it is the screen is right screen which divided by eight. 499 00:36:52,700 --> 00:36:59,600 In this way it is going to take only 8 percent of the width of the screen and for the height you want 500 00:36:59,630 --> 00:37:02,760 this it takes you to be actually wrapped content. 501 00:37:02,810 --> 00:37:10,780 So I can refer to this view group class view group that lay out perhaps that rap content. 502 00:37:10,810 --> 00:37:16,100 So this is actually going to be a value for the height of this. 503 00:37:16,110 --> 00:37:23,680 It takes your view group is going to be the parent here which actually holds this view here. 504 00:37:23,850 --> 00:37:28,800 So just by just referring to this vehicle if we can just the out perhaps and the raw content. 505 00:37:28,900 --> 00:37:34,990 So let me create a new line so that you can see these values better after this line of code here. 506 00:37:35,010 --> 00:37:43,200 I can't say now it's time to add the first text the the name it it takes two or to greedily out. 507 00:37:43,260 --> 00:37:51,270 So just I here it greatly out that at you and here just referred to that multi-dimensional Arey which 508 00:37:51,310 --> 00:37:57,130 is going to be a two dimensional at a EDT names prices and colors so names prices and colors and put 509 00:37:57,130 --> 00:38:00,420 a lot of brackets and forth for the first black to step in here. 510 00:38:00,490 --> 00:38:04,330 Index and let's put another profe brackets here. 511 00:38:04,780 --> 00:38:10,650 And here inside the brackets just put the value zero index number zero right comma. 512 00:38:11,350 --> 00:38:15,590 And here I want to specify the width of this it it takes inside. 513 00:38:15,610 --> 00:38:16,480 It is true. 514 00:38:16,690 --> 00:38:18,700 So that is what I want. 515 00:38:18,720 --> 00:38:27,010 This name it it takes to take to any 8 percent of the width of the screen so I can actually just type 516 00:38:27,010 --> 00:38:30,120 in here with the screen V. 517 00:38:31,260 --> 00:38:36,800 Multiplied by zero point twenty eight comma. 518 00:38:36,860 --> 00:38:40,510 So not in this way it's going to actually take into. 519 00:38:40,600 --> 00:38:43,310 Twenty eight percent of the width of this screen. 520 00:38:43,360 --> 00:38:44,370 This is the formula. 521 00:38:44,600 --> 00:38:48,170 Ok screen with multiplied by 0.2 88. 522 00:38:48,240 --> 00:38:50,940 Now I just need to specify the height of this and it takes. 523 00:38:51,010 --> 00:38:52,320 Is going to be wrapped content. 524 00:38:52,340 --> 00:38:59,510 So I can't just type here via a group that Lay have poems that rap content. 525 00:38:59,520 --> 00:39:04,280 So now let me create a new line here so that you can see these values better. 526 00:39:04,380 --> 00:39:09,300 But here you can see that for the second argument here we need to pass a value of type integer. 527 00:39:09,510 --> 00:39:15,240 But the result of this operation is actually of type float like float or double or decimal value. 528 00:39:15,300 --> 00:39:19,170 So here I need to cast the result of this operation here. 529 00:39:19,170 --> 00:39:23,350 Screen is multiplied by zero point twenty eight to an integer value. 530 00:39:23,490 --> 00:39:29,120 So let's put this operation inside the apprentice's screen which multiplied by zero point eight in say 531 00:39:29,150 --> 00:39:29,950 the practice is. 532 00:39:30,060 --> 00:39:35,890 And before this prentices I can put another pair of practices and I can't just put a value integer here. 533 00:39:35,910 --> 00:39:40,120 So in this way it's going to actually first is isn't as acute this operation here. 534 00:39:40,160 --> 00:39:43,140 Screen which multiplied by zero point twenty eight. 535 00:39:43,230 --> 00:39:47,940 And the result is going to be Chastity's an integer value so this means that the decimal value is going 536 00:39:47,940 --> 00:39:53,330 to be actually the decimal number after the decimal is going to be actually eliminated. 537 00:39:53,400 --> 00:39:58,760 So that's why it is Cester to an integer value here and now you can see that the error is gone. 538 00:39:59,160 --> 00:40:07,950 So now after this line of code I can say let's add the second it takes two or Gridley out inside each 539 00:40:07,950 --> 00:40:08,240 room. 540 00:40:08,280 --> 00:40:08,680 Right. 541 00:40:08,700 --> 00:40:11,400 So after adding the name it takes. 542 00:40:11,460 --> 00:40:13,420 Now it's time to add the price it takes. 543 00:40:13,420 --> 00:40:17,480 So I can't say great lay out that add value. 544 00:40:18,300 --> 00:40:20,650 And again I refer to these two dimensional array. 545 00:40:20,660 --> 00:40:22,980 It is the names prices and colors. 546 00:40:23,010 --> 00:40:29,250 Put a pair of brackets index and again put a pair of brackets again and this time pass the value. 547 00:40:29,250 --> 00:40:31,960 Number one index number one right comma. 548 00:40:32,160 --> 00:40:35,400 And here I need to specify the weight of these idiots. 549 00:40:35,400 --> 00:40:40,430 So I want this editor to take 25 percent of the width of the screen. 550 00:40:40,740 --> 00:40:45,420 So I just put a pair of first again on it which has this value to an integer value so I just put a set 551 00:40:45,420 --> 00:40:46,310 of practices here. 552 00:40:46,530 --> 00:40:58,070 And again I put another pair of practices screen with multiplied by 0.25 write come on. 553 00:40:58,240 --> 00:41:00,050 So this is our second argument. 554 00:41:00,100 --> 00:41:06,130 And finally you need to specify the height of our text so the height is going to be the content view 555 00:41:06,160 --> 00:41:11,000 group that lay out the poems that rap content. 556 00:41:11,020 --> 00:41:13,580 So let me create a new line here. 557 00:41:13,600 --> 00:41:17,450 Now it's time to add our color takes to our greatly. 558 00:41:17,470 --> 00:41:23,600 So lay out that view and I put it here. 559 00:41:23,710 --> 00:41:27,850 I just need to refer to these two dimensional area names prices and colors. 560 00:41:28,210 --> 00:41:35,010 And here just put a pair of brackets index and index number one in this number two actually you are 561 00:41:35,010 --> 00:41:41,140 going to go inside the next number to which is going to be for the color text comma and then here I 562 00:41:41,140 --> 00:41:43,890 just need to specify which of these editors. 563 00:41:43,880 --> 00:41:48,440 So again I want these it takes to take 25 percent of the vote of the screen. 564 00:41:48,520 --> 00:41:55,120 So put up her Apprentice's integer and again put another pair of practices and here refers to this screen 565 00:41:55,180 --> 00:42:03,150 which multiplied by zero is 0.25 0.25. 566 00:42:03,590 --> 00:42:04,310 Come on. 567 00:42:04,310 --> 00:42:09,710 Finally we need to specify the height which is going to be of our content group that lay out perhaps 568 00:42:10,070 --> 00:42:13,070 that wrapped content. 569 00:42:13,120 --> 00:42:15,160 So let me create a new line here. 570 00:42:16,840 --> 00:42:17,320 So that's it. 571 00:42:17,320 --> 00:42:22,110 We added our takes or it takes two or three play out. 572 00:42:22,120 --> 00:42:25,110 Now it's time to add our part into our grittily out. 573 00:42:25,120 --> 00:42:30,050 So here I think 25 percent can be a little bit larger a little bit a bit. 574 00:42:30,100 --> 00:42:31,840 It's going to take a lot of space. 575 00:42:31,840 --> 00:42:38,100 So I think let's change it to 20 percent so just typing zero point 20 percent for the for this it it 576 00:42:38,110 --> 00:42:40,660 takes that you can see this one here. 577 00:42:40,770 --> 00:42:44,800 Index number one which is going to be for the price of that much. 578 00:42:44,980 --> 00:42:51,660 And for this one also it's better to specify that this as it takes to only take 20 percent of the vote 579 00:42:51,760 --> 00:42:52,530 of the screen. 580 00:42:52,540 --> 00:42:58,100 So let's just pass the values 0.20 percent which is 0.20. 581 00:42:58,300 --> 00:43:05,650 So it's Greivis multiplied by 0.20 is going to actually give us that the value of the V which is going 582 00:43:05,650 --> 00:43:09,120 to take only 20 percent of the VIF of this group. 583 00:43:09,130 --> 00:43:17,650 So after this line of code I can't say grittily out duds at view and in here I just need to refer to 584 00:43:17,650 --> 00:43:23,880 these modified buttons at a well if it turns out he just put a pair of brackets index. 585 00:43:23,890 --> 00:43:28,430 So this is going to be the child that I need to specify the width of this button. 586 00:43:28,480 --> 00:43:33,980 So I want this button is modified button to take 30 percent of the width of the screen. 587 00:43:34,120 --> 00:43:41,380 So just refer to this screen be valuable multiplied by zero point fifty. 588 00:43:41,410 --> 00:43:44,950 So because again the result of this operation is going to be off the decimal. 589 00:43:44,950 --> 00:43:51,370 So let's put this operation inside the apprentice's and that here before this prentices with another 590 00:43:51,370 --> 00:43:57,060 proft prentices instead of has just passed a value integer the name integer OK. 591 00:43:57,250 --> 00:44:02,740 And then here finally you need to specify the height of this button which is again going to be that 592 00:44:02,740 --> 00:44:07,740 content view group that lay out columns that wrap content. 593 00:44:08,110 --> 00:44:11,160 So let me create a new line here again. 594 00:44:11,200 --> 00:44:12,720 So now you can see these values better. 595 00:44:12,820 --> 00:44:18,460 So we added all these components to our really out to be added the text view these as it takes. 596 00:44:18,460 --> 00:44:19,910 And finally the button. 597 00:44:20,080 --> 00:44:21,310 Right. 598 00:44:21,310 --> 00:44:26,410 So now it's time to actually put more logic's here. 599 00:44:26,410 --> 00:44:27,130 So not notice that. 600 00:44:27,130 --> 00:44:31,770 Finally here in line number 100 we are adding one value to the value of this index here. 601 00:44:31,780 --> 00:44:33,040 Right. 602 00:44:33,040 --> 00:44:36,770 So now this is our For Look this is our for in loop. 603 00:44:36,820 --> 00:44:45,390 After the ended curly brace of this for in loop here I want to add discretely out to our scroll view. 604 00:44:45,680 --> 00:44:49,290 OK I want to add this Greenly out to our scroll view. 605 00:44:49,450 --> 00:44:55,240 So here after the ending curly brace of this for loop and before the ending curly brace of this modified 606 00:44:55,480 --> 00:45:05,380 user interface Smurfette here I'm going to say scroll view thought I view Great out and I can actually 607 00:45:05,380 --> 00:45:11,260 say set content view scroll view right. 608 00:45:11,330 --> 00:45:14,950 We are calling the set content view here this Mefford here. 609 00:45:14,950 --> 00:45:22,020 So that is going to actually specify that these components are going to be on the screen and we want 610 00:45:22,020 --> 00:45:30,070 the user interface to be actually created programmatically OK not by just referring to us as XML file 611 00:45:30,160 --> 00:45:32,530 we are creating the user interface programmatically. 612 00:45:32,530 --> 00:45:37,570 So we must call sets content to view scroll view the content view is going to be the scroll view. 613 00:45:37,600 --> 00:45:44,410 And finally we need to specify that what is going to happen when the user actually clicks or touches 614 00:45:44,680 --> 00:45:46,380 that modify button. 615 00:45:46,420 --> 00:45:51,860 So that's why we created these Uncle Meffert inside this update Marcheline activity class. 616 00:45:51,880 --> 00:45:54,420 So let's go inside the curly braces of this method here.
