1 00:00:00,460 --> 00:00:06,500 And now as you can see we have this case are that to take box through as you can see here. 2 00:00:06,600 --> 00:00:11,790 So if you are referring to the idea of this checkbox kickboxing as you can see here in say this content 3 00:00:11,850 --> 00:00:17,820 underline minute example if I select this checkbox Wuxi an object as you can see the idea is text box 4 00:00:17,820 --> 00:00:18,230 too. 5 00:00:18,250 --> 00:00:22,590 OK so here it refers to this checkbox here. 6 00:00:22,620 --> 00:00:22,910 OK. 7 00:00:22,950 --> 00:00:29,610 If the ID is checkbox to and if this works is actually checked then it's going to actually execute this 8 00:00:29,610 --> 00:00:34,360 line of code inside of these instead of these curly braces of this statement and break. 9 00:00:34,560 --> 00:00:40,430 And as you can see here we have the other cases here are that ID the checkbox free. 10 00:00:40,500 --> 00:00:45,230 So it's going to actually execute these lines of code here if the idea is six bucks four is going actually 11 00:00:45,270 --> 00:00:46,510 secure these lines of code. 12 00:00:46,680 --> 00:00:51,570 And if the idea is Box 5 checkbox 6 checkbox 7 and tick box. 13 00:00:51,620 --> 00:00:58,320 OK so it's going to actually execute these lines of code inside of these instead of this switch statement. 14 00:00:58,320 --> 00:00:59,180 OK. 15 00:00:59,820 --> 00:01:05,920 So hopefully that makes sense and I think it's actually our project. 16 00:01:06,070 --> 00:01:06,310 OK. 17 00:01:06,330 --> 00:01:07,710 And see what happens. 18 00:01:07,710 --> 00:01:13,610 So now as you can see our application is running on this emulator and if we actually check this checkbox 19 00:01:13,680 --> 00:01:17,760 here that says boxing as you can see it says boxing is checked. 20 00:01:17,760 --> 00:01:18,220 OK. 21 00:01:18,420 --> 00:01:21,680 And if it actually a check of this check box let's see what happens. 22 00:01:21,750 --> 00:01:23,110 As you can see nothing happened. 23 00:01:23,130 --> 00:01:23,770 OK. 24 00:01:24,090 --> 00:01:31,560 So let's actually take this kickboxing checkbooks Kickboxing is checked judo Judo is checked. 25 00:01:31,950 --> 00:01:33,550 I have two. 26 00:01:33,700 --> 00:01:36,920 And here we have a problem for the aikido it actually tossed. 27 00:01:37,220 --> 00:01:39,030 Showed us this football is checked. 28 00:01:39,030 --> 00:01:44,770 So let's actually see what is this value as you can see for the checkbox number four as you can see 29 00:01:44,870 --> 00:01:46,160 one two three four. 30 00:01:46,160 --> 00:01:47,230 So this is our check box. 31 00:01:47,230 --> 00:01:49,870 Number four if you have this football and this is wrong. 32 00:01:49,910 --> 00:01:51,270 We need to actually to change these two. 33 00:01:51,370 --> 00:01:52,360 You do. 34 00:01:53,030 --> 00:01:53,730 OK. 35 00:01:54,280 --> 00:01:58,670 And here as you can see for the checkbox number five we have football. 36 00:01:58,670 --> 00:02:06,080 So this is running community change these two football and for the check box number six we have our 37 00:02:06,080 --> 00:02:07,080 take Wando. 38 00:02:07,370 --> 00:02:10,550 So here we need to change this to take one to 39 00:02:14,090 --> 00:02:18,540 OK and here for the checkbox number seven we have wrestling 40 00:02:22,250 --> 00:02:26,490 and for this checkbox number eight if you have swimming and this is right. 41 00:02:26,510 --> 00:02:27,230 OK. 42 00:02:27,230 --> 00:02:32,090 So let's actually run our project again and see what happens. 43 00:02:32,090 --> 00:02:35,140 So as you can see here now again our application is running. 44 00:02:35,180 --> 00:02:38,580 And if we actually click on this site here that is checked. 45 00:02:38,690 --> 00:02:41,040 Football football is checked. 46 00:02:41,090 --> 00:02:41,850 Take Wando. 47 00:02:41,870 --> 00:02:44,090 Take one that is checked wrestling. 48 00:02:44,090 --> 00:02:47,600 Wrestling is checked and swimming as you can see swimming is Cheikh. 49 00:02:47,630 --> 00:02:48,270 OK. 50 00:02:48,650 --> 00:02:50,590 So hopefully that makes sense. 51 00:02:50,720 --> 00:02:51,300 OK. 52 00:02:51,560 --> 00:02:55,530 And now we want to actually work on this part here. 53 00:02:55,580 --> 00:02:56,140 OK. 54 00:02:56,390 --> 00:03:00,810 So now let's ask you to go inside this uncreate method here. 55 00:03:00,890 --> 00:03:08,540 So now I want to actually make these out as you can see here we have the secret here and I want to actually 56 00:03:08,540 --> 00:03:10,300 make this sequel a listener. 57 00:03:10,490 --> 00:03:11,350 OK. 58 00:03:11,530 --> 00:03:15,300 They're actually seeking to they're actually actively seeking of the user. 59 00:03:15,380 --> 00:03:15,640 OK. 60 00:03:15,650 --> 00:03:17,930 So when they use that actually six These are six. 61 00:03:17,930 --> 00:03:19,830 But here it's going I should respond. 62 00:03:19,880 --> 00:03:25,670 OK so in order to do that you need to actually call it a listen at a specific listener on this see what 63 00:03:25,730 --> 00:03:26,180 object. 64 00:03:26,180 --> 00:03:30,270 So first of all I need to actually be fair to the name of this sick object OK. 65 00:03:30,350 --> 00:03:33,180 That we actually declared in our class as you can see here. 66 00:03:33,200 --> 00:03:37,020 And then we actually instantiate that object here. 67 00:03:37,220 --> 00:03:45,470 As you can see in line 54 and now I just need to refer to the name of the seat but object that sits 68 00:03:45,860 --> 00:03:49,460 on six bar change listener. 69 00:03:49,490 --> 00:03:54,310 And now inside Apprentice's I need to actually specify the context. 70 00:03:54,330 --> 00:03:56,430 OK main activity that this. 71 00:03:56,500 --> 00:03:57,210 OK. 72 00:03:57,290 --> 00:04:02,750 And as you can see it's showing us and it and we need to actually implement another kind of interface. 73 00:04:02,750 --> 00:04:08,500 So here in order to implement an order in interface in our class. 74 00:04:08,510 --> 00:04:09,070 OK. 75 00:04:09,140 --> 00:04:11,220 So we need to actually put in a comma here. 76 00:04:11,300 --> 00:04:11,970 OK. 77 00:04:12,050 --> 00:04:15,010 And then we need to actually implement that interface here. 78 00:04:15,020 --> 00:04:20,560 So here I just need to typing in on switchboard change listener. 79 00:04:20,820 --> 00:04:21,410 OK. 80 00:04:21,530 --> 00:04:28,760 So when I use it I try to interact with the listener as you can see here in our app if you need to actually 81 00:04:29,210 --> 00:04:33,060 implement this interface part that unsichtbare change listener. 82 00:04:33,110 --> 00:04:33,810 OK. 83 00:04:34,070 --> 00:04:39,290 As you can see here and we need to actually implement it actually the abstract methods that we actually 84 00:04:39,290 --> 00:04:44,980 inherit from this implement is interface. 85 00:04:45,170 --> 00:04:50,520 OK we need to actually implement those abstract methods in our class. 86 00:04:50,570 --> 00:04:56,630 So here are in our class as you can see of we need to actually implement that method. 87 00:04:56,630 --> 00:05:01,580 So here I can actually after the end in curly brace of this uncreate Smurfette I can get you to right 88 00:05:01,580 --> 00:05:07,090 click here click on this generate and then click on employment benefits. 89 00:05:07,250 --> 00:05:12,860 And as you can see here these are the freely acquired the Misfit's that we need to implement in our 90 00:05:12,860 --> 00:05:18,540 class as you can see it says Android that we did that switchboard data on six but changelessness. 91 00:05:18,590 --> 00:05:23,840 So as you can see this is actually an interface and these are the Misfit's that diskless need to actually 92 00:05:23,840 --> 00:05:24,440 implement. 93 00:05:24,440 --> 00:05:25,030 OK. 94 00:05:25,250 --> 00:05:27,620 So here again just click on OK. 95 00:05:27,680 --> 00:05:33,040 So as you can see here now we have free methods that we need to actually overwrite in our class. 96 00:05:33,050 --> 00:05:33,800 OK. 97 00:05:34,090 --> 00:05:41,600 You can actually not to overwrite these misfits but what the most important one is this Meffert on progress 98 00:05:41,600 --> 00:05:42,240 changed. 99 00:05:42,320 --> 00:05:47,370 So this lift is going is going to be called Venditte been used use and actually change this. 100 00:05:47,460 --> 00:05:50,730 So people here and they use that is actually seeking on the search bar. 101 00:05:50,750 --> 00:05:51,370 OK. 102 00:05:51,560 --> 00:05:56,400 So now as you can see the Smurfit actually are routine enough. 103 00:05:56,540 --> 00:05:59,110 And this actually accepts free arguments. 104 00:05:59,150 --> 00:06:02,440 The first one is the but itself this but object. 105 00:06:02,480 --> 00:06:04,750 The second one is the progress of the sick bar. 106 00:06:05,000 --> 00:06:05,510 OK. 107 00:06:05,720 --> 00:06:08,810 So then they use that actually change this. 108 00:06:08,900 --> 00:06:11,490 When they use it is actually seeking on this sick part. 109 00:06:11,510 --> 00:06:14,250 As you can see it's going to generate an integer value. 110 00:06:14,250 --> 00:06:14,720 OK. 111 00:06:14,900 --> 00:06:19,620 So we can I truly get that integer value by just referring to this argument to progress. 112 00:06:19,640 --> 00:06:26,250 OK so we can actually access this value by using this progress argument here. 113 00:06:26,510 --> 00:06:31,150 And we have another argument that is of type Boolean and this is from user. 114 00:06:31,270 --> 00:06:31,740 OK. 115 00:06:31,820 --> 00:06:35,620 So insight is our Meffert we can actually put in our own implementations. 116 00:06:35,630 --> 00:06:36,040 OK. 117 00:06:36,200 --> 00:06:41,210 So here I'm going to actually explain that pasting some lines of code here and then I'm going to explain 118 00:06:41,210 --> 00:06:42,600 to you what's going on here. 119 00:06:42,890 --> 00:06:47,550 So as you can see here I actually created a host object and then I called the shawm if it stopped. 120 00:06:47,560 --> 00:06:52,420 So on this toast object in order to actually show this object to the user. 121 00:06:52,580 --> 00:06:57,700 So TOSed that make text on the first argument is the context main activity that this. 122 00:06:57,860 --> 00:06:59,190 And he had of double quotes. 123 00:06:59,240 --> 00:07:07,580 I just typed in that the current value of the C Barby's colon space and he had actually used up plus 124 00:07:07,580 --> 00:07:11,210 operator in order to concatenate this value with the value of the program. 125 00:07:11,210 --> 00:07:16,820 OK so when the user is actually seeking undischarged we can see that specific value. 126 00:07:16,820 --> 00:07:21,460 And here this is the actually the duration of the text that is going shown to the user. 127 00:07:21,590 --> 00:07:23,800 And here we are calling this show. 128 00:07:23,860 --> 00:07:28,240 And this object in order to show it is up to us object to the use that. 129 00:07:28,240 --> 00:07:28,620 OK. 130 00:07:28,660 --> 00:07:30,990 So as you can see here this is the tallest object. 131 00:07:31,210 --> 00:07:36,210 And now we have this on started tracking touch. 132 00:07:36,240 --> 00:07:39,530 OK this is another method from the search bar interface. 133 00:07:39,610 --> 00:07:40,210 OK. 134 00:07:40,210 --> 00:07:44,930 And this is going to be called when the user actually starts to actually see. 135 00:07:45,190 --> 00:07:48,700 OK Vinnie use starts to seek this in if it is going to be called. 136 00:07:48,820 --> 00:07:49,280 OK. 137 00:07:49,390 --> 00:07:55,000 And we can actually create a tossed object here and it'll And we can actually show that object to the 138 00:07:55,000 --> 00:07:55,590 user. 139 00:07:55,750 --> 00:07:59,770 So here I'm going to actually paste in a toast object and then I'm going to explain to you what's going 140 00:07:59,770 --> 00:08:00,270 on here. 141 00:08:00,310 --> 00:08:04,480 So as you can see here this is the line of code that actually pasted here. 142 00:08:04,780 --> 00:08:06,400 These tools that make text. 143 00:08:06,400 --> 00:08:12,000 So first of all I specified the context main activity that this and he had instead of double quotes 144 00:08:12,070 --> 00:08:13,200 I just typed in. 145 00:08:13,210 --> 00:08:15,520 Now that bar is started. 146 00:08:15,670 --> 00:08:21,300 And here you are specifying the activity the duration of the text that is going to be shown to the user. 147 00:08:21,310 --> 00:08:24,060 And we are calling this method show my foot on this object. 148 00:08:24,100 --> 00:08:24,660 OK. 149 00:08:24,880 --> 00:08:28,110 And we have this effect on a stop a tracking touch. 150 00:08:28,120 --> 00:08:33,110 So the Smurfette as you can see here this on start liking touchier is going to be called when the user 151 00:08:33,130 --> 00:08:35,950 is Tharp's actually seeking under siege. 152 00:08:35,980 --> 00:08:42,550 OK so as you can see here I am actually sitting on the bar and when I actually stop then decide if it 153 00:08:42,550 --> 00:08:43,770 is going to be called. 154 00:08:44,000 --> 00:08:48,660 Ok so now we can actually create another object here. 155 00:08:48,730 --> 00:08:51,360 So as you can see here this is my toast object. 156 00:08:51,370 --> 00:08:51,890 OK. 157 00:08:51,910 --> 00:08:56,550 First of all I specified the context and then this is the text that I want to show to the user. 158 00:08:56,560 --> 00:08:58,420 Now the bar is stopped. 159 00:08:58,510 --> 00:08:59,110 OK. 160 00:08:59,230 --> 00:09:02,510 And we have these tostada length short and tacho. 161 00:09:02,620 --> 00:09:07,210 OK so now let's actually run our project and see what happens. 162 00:09:07,210 --> 00:09:12,050 So now as you can see our application is actually running on DS emulator. 163 00:09:12,120 --> 00:09:12,670 OK. 164 00:09:12,790 --> 00:09:17,560 And now if we actually want to change the value of the search bar let's see what happens. 165 00:09:17,560 --> 00:09:19,960 OK so I'm just going to start it here. 166 00:09:19,960 --> 00:09:22,510 I'm just going to start here and now. 167 00:09:22,540 --> 00:09:28,210 Now the bar is started and now as you can see the current value of the bar is number free. 168 00:09:28,210 --> 00:09:29,990 Now the pot is stopped. 169 00:09:30,070 --> 00:09:31,010 OK. 170 00:09:31,180 --> 00:09:36,060 So as you can see here these are three kinds of methods actually called here. 171 00:09:36,070 --> 00:09:37,040 OK. 172 00:09:37,120 --> 00:09:40,360 So hopefully that makes sense. 173 00:09:40,360 --> 00:09:41,040 OK. 174 00:09:41,170 --> 00:09:47,770 And now we have these orating bar here and we have these are radio buttons that are actually the inside 175 00:09:47,830 --> 00:09:49,830 of another radio group. 176 00:09:49,840 --> 00:09:50,410 OK. 177 00:09:50,620 --> 00:09:51,680 So let's actually work on this. 178 00:09:51,680 --> 00:09:52,660 Orating bar here. 179 00:09:52,810 --> 00:09:53,390 OK. 180 00:09:53,460 --> 00:09:54,430 And let's actually go inside. 181 00:09:54,430 --> 00:09:56,120 These are uncreate Mefford. 182 00:09:56,170 --> 00:09:56,690 OK. 183 00:09:56,860 --> 00:10:01,370 So first of all now I want to actually make this a rating for our listener. 184 00:10:01,450 --> 00:10:01,980 OK. 185 00:10:02,110 --> 00:10:03,120 Or two the clicks of the user. 186 00:10:03,130 --> 00:10:08,210 OK so for example when the user wants to actually change the value of this routine. 187 00:10:08,260 --> 00:10:12,580 You hear this rating but you can actually do something with those values. 188 00:10:12,580 --> 00:10:13,070 OK. 189 00:10:13,360 --> 00:10:16,950 So here I just need to refer to the name of this object rating bar. 190 00:10:17,260 --> 00:10:17,750 OK. 191 00:10:17,860 --> 00:10:22,840 As you can see if you declare this object in class and then be instantiated this object here in this 192 00:10:23,140 --> 00:10:23,850 uncreate Meffert. 193 00:10:23,860 --> 00:10:24,350 OK. 194 00:10:24,430 --> 00:10:30,430 So letting bar dots sets on rating board change listener. 195 00:10:30,430 --> 00:10:30,980 OK. 196 00:10:31,120 --> 00:10:37,510 So in this way we are actually making this retty but a listener today actually the clips up the user 197 00:10:37,690 --> 00:10:40,430 so that the user can actually change the value of the rating. 198 00:10:40,450 --> 00:10:43,090 And then we can actually do something with those values. 199 00:10:43,090 --> 00:10:43,550 OK. 200 00:10:43,780 --> 00:10:50,910 So here lately but that said sit on rating will change the center and that he had Vinita actually specify. 201 00:10:51,130 --> 00:10:54,640 Actually the class that this listener actually belongs to. 202 00:10:54,700 --> 00:11:02,200 So he had just that main activity thought this and now we need to actually implement the under-18 bar 203 00:11:02,350 --> 00:11:03,230 change the center. 204 00:11:03,280 --> 00:11:03,830 OK. 205 00:11:03,970 --> 00:11:10,840 So here in our class as you can see if you need to actually put another comma here and here I can just 206 00:11:10,840 --> 00:11:12,120 type in rating board. 207 00:11:12,340 --> 00:11:12,760 OK. 208 00:11:12,800 --> 00:11:17,220 Dot under-rating bar change listener. 209 00:11:17,420 --> 00:11:21,650 So as you can see here Rating Board darts under-18 bar change listener. 210 00:11:21,650 --> 00:11:22,160 OK. 211 00:11:22,340 --> 00:11:25,480 And now we can actually scroll down here. 212 00:11:25,490 --> 00:11:30,890 And after the end in brace of this uncreate Meffert I can actually right click here. 213 00:11:31,130 --> 00:11:33,450 And then I can actually click on generate. 214 00:11:33,800 --> 00:11:37,090 And here I can actually kind of implement Moffats. 215 00:11:37,130 --> 00:11:42,240 So this is the method that we need to implement locate and do that which is that rating board that aren't 216 00:11:42,250 --> 00:11:43,810 rating board change to the center. 217 00:11:43,830 --> 00:11:48,740 And this is actually inside these interface OK under-18 changed. 218 00:11:48,800 --> 00:11:52,000 So here I can actually click on OK. 219 00:11:52,280 --> 00:11:54,390 And now as you can see the error is gone. 220 00:11:54,390 --> 00:11:58,460 And now we can actually overwrite this R-rating changed the Senate here. 221 00:11:58,460 --> 00:11:59,020 OK. 222 00:11:59,300 --> 00:12:03,920 So in so far as you can see if you have this buffer it actually returns nothing. 223 00:12:03,980 --> 00:12:09,080 And this if it actually exits free arguments the first one is the rating rating but object so the slaking 224 00:12:09,080 --> 00:12:12,540 bar here and the next one is the value of the rating. 225 00:12:12,540 --> 00:12:17,210 So here for example are four stars of four point one five stars. 226 00:12:17,210 --> 00:12:28,790 As you can see here for example three point one four stars 4.1 five stars or even one star two star 227 00:12:28,850 --> 00:12:29,840 or other values. 228 00:12:29,870 --> 00:12:36,500 So this is that value rating which is of type float and we have this Boullion argument from use it. 229 00:12:36,530 --> 00:12:37,040 OK. 230 00:12:37,160 --> 00:12:42,080 So now inside this under-rating changed I want you to paste in a line of code and then I'm going explain 231 00:12:42,080 --> 00:12:43,320 to you what's going on here. 232 00:12:43,460 --> 00:12:47,930 So this is the line of code that they actually pasted here TOSed that make text. 233 00:12:47,930 --> 00:12:51,680 First of all I actually specified the context of our application. 234 00:12:51,680 --> 00:12:56,120 The second argument is actually the text that I want to show to the use that the number of stars are 235 00:12:56,540 --> 00:12:57,170 rating. 236 00:12:57,290 --> 00:13:04,730 OK so that can we can actually understand we can actually get the value of these rating but here for 237 00:13:04,730 --> 00:13:07,630 example four stars three point one or five stars. 238 00:13:07,760 --> 00:13:12,260 OK so with this rating the number of stars are in space rating. 239 00:13:12,470 --> 00:13:16,880 And here it says it was started in short so this is that the ration of the text that we want to show 240 00:13:16,880 --> 00:13:18,620 to the user that's sure. 241 00:13:18,860 --> 00:13:23,740 OK so now let's actually run our project and see what happens.
