1 00:00:00,510 --> 00:00:04,490 So now it's actually going inside this uncreate method as you can see here. 2 00:00:04,590 --> 00:00:05,140 OK. 3 00:00:05,140 --> 00:00:09,600 And when I actually are pasting some lines of code here and then I'm going to explain to you what's 4 00:00:09,600 --> 00:00:10,980 going on here. 5 00:00:11,010 --> 00:00:14,500 So as you can see here these are the lines of code that they actually paste that here. 6 00:00:14,520 --> 00:00:15,180 OK. 7 00:00:15,180 --> 00:00:20,890 So here as you can see in line 60 I said that used the animation for Takes suture. 8 00:00:21,030 --> 00:00:24,780 So here I am actually calling these Smurfette that I actually created here. 9 00:00:24,810 --> 00:00:25,340 OK. 10 00:00:25,350 --> 00:00:27,070 Use the animation for texture. 11 00:00:27,120 --> 00:00:32,270 So this if it is going to actually put those animation effects on these or take suture objects. 12 00:00:32,370 --> 00:00:37,410 So as you can see here inside this emulator if I click on this next button or this previous button we 13 00:00:37,410 --> 00:00:39,350 can see those are animation effects. 14 00:00:39,360 --> 00:00:39,740 OK. 15 00:00:39,840 --> 00:00:43,440 So I am passing this take these take which objects to these methods. 16 00:00:43,440 --> 00:00:43,930 OK. 17 00:00:43,980 --> 00:00:46,380 For example this one is for this a sweeter one. 18 00:00:46,620 --> 00:00:52,030 And this one is for this I take sweet two and this one is for these tapes which are free object. 19 00:00:52,050 --> 00:00:52,530 OK. 20 00:00:52,710 --> 00:00:55,700 As you can see if you have free the fence takes three years. 21 00:00:56,040 --> 00:01:01,770 And now I actually paste in some lines of code here and then I'm going to explain to you what's going 22 00:01:01,770 --> 00:01:02,470 on. 23 00:01:02,490 --> 00:01:06,130 So as you can see here these are the lines of code that they actually paste that here. 24 00:01:06,300 --> 00:01:06,860 OK. 25 00:01:06,900 --> 00:01:12,270 And here in line 65 as you can see I actually called this May 5th create takes you by either reading 26 00:01:12,330 --> 00:01:14,720 or the values of the three four takes through each year. 27 00:01:14,730 --> 00:01:18,000 So as you can see here I created this method here as you can see. 28 00:01:18,240 --> 00:01:22,960 And these are for actually accepts two arguments string values and text to each other. 29 00:01:22,980 --> 00:01:28,580 So here are for the first argument I actually assigned this string values Von Schrader. 30 00:01:28,620 --> 00:01:32,610 They actually created inside this class here in line 28 as you can see here. 31 00:01:33,000 --> 00:01:36,650 And for the second argument I actually assigned this text which had object 1. 32 00:01:36,750 --> 00:01:40,310 As you can see and here again I called that method again here. 33 00:01:40,530 --> 00:01:46,440 And for the first argument scientists are string values to and for the second argument I assigned the 34 00:01:46,440 --> 00:01:47,010 value. 35 00:01:47,010 --> 00:01:48,870 This takes three to two. 36 00:01:49,140 --> 00:01:54,750 And here I actually again called this method creates takes you by either reading over the values of 37 00:01:54,750 --> 00:01:56,290 the add a fourth text sweeter. 38 00:01:56,460 --> 00:02:02,130 And here again for the first argument I actually assign string values free and for the second argument 39 00:02:02,190 --> 00:02:04,020 I assigned takes three free. 40 00:02:04,140 --> 00:02:04,880 OK. 41 00:02:05,010 --> 00:02:06,950 So hopefully that makes sense. 42 00:02:07,020 --> 00:02:14,100 And now I'm going to actually pasting some lines of code here and then I'm going to explain to you what's 43 00:02:14,100 --> 00:02:14,950 going on here. 44 00:02:14,970 --> 00:02:15,670 OK. 45 00:02:16,050 --> 00:02:20,430 So as you can see here these are the lines of code that they actually pasted here and here as you can 46 00:02:20,430 --> 00:02:23,920 see first of all I referred to the name of this button here. 47 00:02:23,970 --> 00:02:30,420 Next one object as you can see inside the emulator and here this is our next button and this is our 48 00:02:30,420 --> 00:02:31,330 previous button. 49 00:02:31,350 --> 00:02:31,950 OK. 50 00:02:32,220 --> 00:02:37,300 And here I am actually making this button a listener as you can see listening to the clicks of the use. 51 00:02:37,320 --> 00:02:40,160 So if I click on this button something is going to happen. 52 00:02:40,230 --> 00:02:40,660 OK. 53 00:02:40,740 --> 00:02:43,140 So bit here next one that Stankovic listener. 54 00:02:43,260 --> 00:02:46,590 And here inside Apprentice's we need to specify the context. 55 00:02:46,590 --> 00:02:51,580 OK we need to specify the class that is going to be the listener of the clicks of the user. 56 00:02:51,630 --> 00:02:52,120 OK. 57 00:02:52,130 --> 00:02:55,610 You need to specify the class that this listener belongs to. 58 00:02:55,710 --> 00:02:56,430 OK. 59 00:02:56,430 --> 00:03:01,620 So here again in line 71 I with the name of the city and a private object. 60 00:03:01,620 --> 00:03:06,970 So this is BT and prevent object as you can see that Stokley class and in main activity that this. 61 00:03:07,140 --> 00:03:07,640 OK. 62 00:03:07,860 --> 00:03:14,360 BT are next to that Satanical class and our main activity that this Pythian preach to a listener. 63 00:03:14,480 --> 00:03:21,630 My main activity at this as you can see here and here Pythian our next free set unclick listener main 64 00:03:21,630 --> 00:03:25,870 activity at this and here as you can see PTEN are pretty free. 65 00:03:25,890 --> 00:03:28,420 That's what our calculus and our main activity that is. 66 00:03:28,440 --> 00:03:33,400 OK so now I want to I need to actually as you can see it's not an error. 67 00:03:33,440 --> 00:03:38,220 OK so we cannot actually run our project now because the compiler is actually complaining and we need 68 00:03:38,220 --> 00:03:43,560 to fix something here and here because we are actually making these buttons. 69 00:03:43,650 --> 00:03:49,260 I listen to the clicks of the user we need to actually implement the unclick listener interface in our 70 00:03:49,260 --> 00:03:49,870 class. 71 00:03:49,980 --> 00:03:54,310 Ok so here at the top you need to just type it here implements. 72 00:03:54,500 --> 00:03:59,490 So main activity implements unclick listener interface unclick listener. 73 00:03:59,570 --> 00:04:01,200 OK view that unclick listener. 74 00:04:01,200 --> 00:04:01,640 OK. 75 00:04:01,860 --> 00:04:07,570 So now because this unclick listener interface is actually abstract. 76 00:04:07,790 --> 00:04:13,260 We need to actually implement the abstract methods that are inside of this class and or interface. 77 00:04:13,260 --> 00:04:21,030 So here after the end in calibrates of each of these uncreate Smurfette you know here we need to actually 78 00:04:21,300 --> 00:04:26,820 implement that Anklage my faith here on click Meffert and that he had need to press on until key on 79 00:04:26,820 --> 00:04:28,360 my keyboard. 80 00:04:28,380 --> 00:04:31,890 So now as you can see we can actually overwrite this ugly MF. 81 00:04:31,920 --> 00:04:32,470 OK. 82 00:04:32,670 --> 00:04:36,660 So inside of this Meffert I'm going to actually paste in some lines of code and then I'm going to explain 83 00:04:36,660 --> 00:04:38,320 to you what's going on here. 84 00:04:38,340 --> 00:04:43,080 So as you can see here I actually pasted this switch statement here as you can see. 85 00:04:43,080 --> 00:04:43,580 OK. 86 00:04:43,770 --> 00:04:47,890 So this is the statement that actually pasted here inside of this Uncle Fred. 87 00:04:47,940 --> 00:04:48,550 OK. 88 00:04:48,850 --> 00:04:52,380 And now when I explain to you what's going on here. 89 00:04:52,380 --> 00:04:55,120 First of all I actually created a switch statement. 90 00:04:55,180 --> 00:05:00,890 So each and inside the apprentice's I actually fed to the name of this object that we actually to receive 91 00:05:00,920 --> 00:05:04,030 as an argument view OK this object is of type view. 92 00:05:04,040 --> 00:05:10,060 So remember view the view class is actually the superclass of all of these components in actually and 93 00:05:10,090 --> 00:05:10,760 right stick. 94 00:05:10,830 --> 00:05:11,260 OK. 95 00:05:11,450 --> 00:05:16,790 So if you want to actually differentiate between the buttons OK between these different buttons I can 96 00:05:16,790 --> 00:05:20,510 actually use this view object in order to differentiate between those buttons. 97 00:05:20,600 --> 00:05:23,600 When the user clicks on one of those buttons. 98 00:05:23,600 --> 00:05:24,040 OK. 99 00:05:24,170 --> 00:05:26,920 So here I can just type in each that gets ID. 100 00:05:26,960 --> 00:05:34,340 OK so here and just switching between the ideas that are related to our objects so get to the bottom. 101 00:05:34,360 --> 00:05:36,580 OK so we don't get ID. 102 00:05:36,860 --> 00:05:38,930 And here inside is a switch statement. 103 00:05:38,960 --> 00:05:48,470 I am saying that if the ID of our view as we can see it if the idea of our V object is PTEN next one 104 00:05:48,740 --> 00:05:50,890 then execute this line of code here. 105 00:05:50,960 --> 00:05:54,820 It takes Screecher want that show next here as you can see break. 106 00:05:55,160 --> 00:06:01,550 And here we have case art that idea that and Livan takes through each one that show previous. 107 00:06:01,550 --> 00:06:05,760 So as you can see here in the emulator we have these values here. 108 00:06:05,780 --> 00:06:10,160 And if I click Next you can see the next value. 109 00:06:10,160 --> 00:06:14,190 And if I click on previous As you can see we can see the previous value OK. 110 00:06:14,630 --> 00:06:21,860 And here again if the value of this ID is a bit here next to then execute this line of code here takes 111 00:06:21,870 --> 00:06:22,520 three to two. 112 00:06:22,510 --> 00:06:24,370 That's your next break. 113 00:06:24,530 --> 00:06:29,710 And if the value of this idea is PTEN P2 takes each to the previous bridge. 114 00:06:29,950 --> 00:06:30,280 OK. 115 00:06:30,280 --> 00:06:33,350 And as you can see here we have another text we show here. 116 00:06:33,470 --> 00:06:39,620 And if I click on next and see the next value and if I click on previous You can see the previous value. 117 00:06:39,680 --> 00:06:45,800 And here again we have another case statement case are that ID that's BTA next three take Sutor free. 118 00:06:45,800 --> 00:06:54,180 That's your next break case or that Id that BT and briefly take take to read your previous break. 119 00:06:54,200 --> 00:06:59,360 So here as you can see if you scroll down you can see that you have another take switcher and if we 120 00:06:59,360 --> 00:07:04,740 click Next we can see this value the next value completely ASBI level up of course. 121 00:07:04,790 --> 00:07:09,770 And if I click on a previous We can see the previous value complete objective see that of course. 122 00:07:09,770 --> 00:07:10,680 OK. 123 00:07:10,820 --> 00:07:12,860 So hopefully that makes sense. 124 00:07:13,040 --> 00:07:13,640 OK. 125 00:07:13,880 --> 00:07:20,290 And I think that's enough for this application and it's actually not our project and see what happens. 126 00:07:20,590 --> 00:07:26,900 OK so now as you can see our application is actually running on this emulator. 127 00:07:26,960 --> 00:07:27,540 OK. 128 00:07:27,740 --> 00:07:29,110 And here you can see these values. 129 00:07:29,120 --> 00:07:34,070 And if I actually click on the spot in here you can see these values actually are changing your cake. 130 00:07:34,400 --> 00:07:39,300 And here here and actually if you scroll down here I can see these values change. 131 00:07:39,440 --> 00:07:44,090 But as you can see here these buttons are not at the center of this screen. 132 00:07:44,090 --> 00:07:44,520 OK. 133 00:07:44,690 --> 00:07:47,810 So here are they're not actually horizontally centered. 134 00:07:47,900 --> 00:07:50,220 They are actually horizontally centered. 135 00:07:50,240 --> 00:07:56,930 But because if actually signed this we actually when we actually selected these linear layouts that 136 00:07:56,930 --> 00:08:05,190 actually hold these image buttons of actually assigned the value wrapped content for these up linearly. 137 00:08:05,240 --> 00:08:12,500 OK so if we actually change these values for the new outfits and for that they are for the layout and 138 00:08:12,500 --> 00:08:15,340 for the layout height as you can see the assigned lap content. 139 00:08:15,350 --> 00:08:15,940 OK. 140 00:08:16,340 --> 00:08:21,420 And if we actually change this value it will match parent. 141 00:08:21,440 --> 00:08:22,560 Let's see what happens. 142 00:08:24,090 --> 00:08:25,740 As you can see match parent. 143 00:08:25,740 --> 00:08:29,700 And now let's actually do our project again and see what happens. 144 00:08:31,670 --> 00:08:35,410 And now as you can see these two buttons are actually at the center. 145 00:08:35,420 --> 00:08:38,870 Actually there are they are horizontally centered on the screen. 146 00:08:38,870 --> 00:08:39,310 OK. 147 00:08:39,500 --> 00:08:45,320 And that's because this linearly out now is actually that lay outfits and the height of this linearly 148 00:08:45,330 --> 00:08:49,930 out is match parent OK and match parent means the parent of this linearly. 149 00:08:49,940 --> 00:08:54,180 So that part of this linearly out is this linearly outwards. 150 00:08:54,200 --> 00:08:54,650 OK. 151 00:08:54,920 --> 00:09:01,800 So here because we actually is trying to devalue match parents for these outfits and for the length 152 00:09:01,880 --> 00:09:09,320 height of these linearly owls now because these two actually assigned the values centered horizontal 153 00:09:09,320 --> 00:09:16,820 for the gravity of this linearly and vertical the components that are inside of this linearly are going 154 00:09:16,820 --> 00:09:23,070 to be actually horizontally centered inside this linearly and actually horizontal OK. 155 00:09:23,150 --> 00:09:30,830 But when you actually assigned the value wrapped content to the left and to the height of this linearly 156 00:09:30,830 --> 00:09:34,090 or horizontal or the values are going to be centered. 157 00:09:34,160 --> 00:09:34,760 OK. 158 00:09:34,850 --> 00:09:38,780 Inside that specific linearly or horizontal okay but we cannot. 159 00:09:38,810 --> 00:09:44,220 But when we actually got our application like this as you can see you cannot actually see that that 160 00:09:44,220 --> 00:09:50,070 they are centered inside the linearly or horizontal but they are not centered in sight our screen. 161 00:09:50,220 --> 00:09:56,050 OK but if we actually change that value that they have to feed and the height too much apparent. 162 00:09:56,150 --> 00:09:58,980 Now they are actually centered horizontally in the screen. 163 00:09:59,170 --> 00:09:59,740 OK. 164 00:10:00,050 --> 00:10:03,840 So if I actually decide actually select the other linearly out. 165 00:10:03,890 --> 00:10:04,470 OK. 166 00:10:04,730 --> 00:10:05,200 OK. 167 00:10:05,300 --> 00:10:11,990 And now I can actually change this outfit to to actually match a parent. 168 00:10:12,230 --> 00:10:14,830 And then they have height to match parent. 169 00:10:14,840 --> 00:10:15,540 OK. 170 00:10:15,650 --> 00:10:20,790 I actually assigned the value of match parent for outfits and de-value Mattapan and for that they have 171 00:10:20,800 --> 00:10:23,670 height for these two linear layouts here. 172 00:10:23,690 --> 00:10:24,230 OK. 173 00:10:24,470 --> 00:10:29,460 And now if I actually select all of these linearly out horizontally as you can see here the left with 174 00:10:29,480 --> 00:10:34,940 as much apparent and the height is much apparent And as you can see here we cannot see Aldo's image 175 00:10:34,940 --> 00:10:36,660 buttons any more here on this layer. 176 00:10:36,680 --> 00:10:37,060 OK. 177 00:10:37,160 --> 00:10:40,790 But if we actually did not our project here let's see what happens. 178 00:10:42,230 --> 00:10:47,900 And now as you can see our application is running on the simulator and we can see that these image buttons 179 00:10:47,900 --> 00:10:52,820 are actually centered horizontally correctly OK on our inside the screen. 180 00:10:52,820 --> 00:10:53,300 OK. 181 00:10:53,390 --> 00:10:58,370 And here we can see these values and here you can actually click on these image buttons in order to 182 00:10:58,370 --> 00:10:59,880 change these values. 183 00:10:59,900 --> 00:11:00,370 OK.
