1 00:00:00,270 --> 00:00:07,320 So now as you can see our application is running on this emulator and here I can actually select this 2 00:00:07,680 --> 00:00:12,630 rating but here for example I want to actually assign the value of three stars and now as you can see 3 00:00:12,630 --> 00:00:19,710 it says the number of stars are 2.4 2.5 get the value of this rating but is 2.5 or can actually make 4 00:00:19,910 --> 00:00:22,190 your stars the number of stars are free. 5 00:00:22,200 --> 00:00:22,980 Point zero. 6 00:00:23,120 --> 00:00:24,730 OK. 7 00:00:24,790 --> 00:00:28,230 As you can see it says the number of stars are 3.5. 8 00:00:28,230 --> 00:00:31,050 The number of stars are four I can actually change. 9 00:00:31,050 --> 00:00:37,040 This takes two other takes for example the value of stars are here I can actually change these numbers 10 00:00:37,080 --> 00:00:38,640 to value. 11 00:00:38,880 --> 00:00:41,890 And now it's actually on our project again. 12 00:00:41,970 --> 00:00:48,180 So now I can actually give value to the rating board for example here the value of stars are free or 13 00:00:48,180 --> 00:00:49,480 here or here. 14 00:00:49,620 --> 00:00:51,960 You can actually see this value here or here. 15 00:00:51,960 --> 00:00:52,550 OK. 16 00:00:52,560 --> 00:00:54,410 So you can see this TOSed object here. 17 00:00:54,450 --> 00:00:55,330 OK. 18 00:00:55,350 --> 00:00:57,160 So hopefully that makes sense. 19 00:00:57,550 --> 00:01:02,250 And now we have these are radio buttons inside our radio group. 20 00:01:02,250 --> 00:01:08,670 So now I want to make these radio buttons that are inside of an order or radio group I want to make 21 00:01:08,670 --> 00:01:11,880 these radio buttons a listener to the police if they use that. 22 00:01:11,880 --> 00:01:12,420 OK. 23 00:01:12,420 --> 00:01:17,340 So because these radio buttons are actually inside of an other radio group. 24 00:01:17,400 --> 00:01:23,690 I need to actually type in here a radio group that sits on checked change. 25 00:01:23,690 --> 00:01:24,510 Listener. 26 00:01:24,720 --> 00:01:25,140 OK. 27 00:01:25,260 --> 00:01:30,880 So many to actually call this method on the object radio group that said unchecked change the listener 28 00:01:31,350 --> 00:01:36,190 and inside the prentices I need to pass in the context main activity that is OK. 29 00:01:36,330 --> 00:01:42,060 And now we need to actually implement their antic change listen at of Radio Group here in our class. 30 00:01:42,240 --> 00:01:45,610 So here I just need to put in a comma here. 31 00:01:45,750 --> 00:01:51,520 Radio Group OK that on check out change listener. 32 00:01:51,740 --> 00:01:52,180 OK. 33 00:01:52,320 --> 00:01:55,590 And now we to actually implement the required methods. 34 00:01:55,590 --> 00:02:00,750 So after the end in curly brace of this uncreate method here are connected to right click on my class 35 00:02:01,190 --> 00:02:06,100 and click on generate and then click on implement methods. 36 00:02:06,360 --> 00:02:10,280 And as you can see here we need to actually implement this Antek change a method here. 37 00:02:10,290 --> 00:02:10,740 OK. 38 00:02:10,770 --> 00:02:14,750 That is inside of this on take it or change the center interface. 39 00:02:14,760 --> 00:02:16,730 So here I just need to click on OK. 40 00:02:16,890 --> 00:02:19,310 I just need to select the Smurfit and then click on OK. 41 00:02:19,410 --> 00:02:23,690 So this is my fifth and here as you can see if it returns void. 42 00:02:23,880 --> 00:02:28,410 And this means that if it is going to return nothing that the name of this man if it is on take the 43 00:02:28,410 --> 00:02:30,950 change and this reflection to accepts two arguments. 44 00:02:30,960 --> 00:02:33,890 Ok Radio Group group and checked ID. 45 00:02:34,080 --> 00:02:34,720 OK. 46 00:02:35,040 --> 00:02:37,950 And a district ID is the ID of. 47 00:02:38,040 --> 00:02:40,960 Actually the radio buttons inside the radio group. 48 00:02:40,980 --> 00:02:45,190 OK so we can actually access these are objects these radio buttons. 49 00:02:45,270 --> 00:02:46,740 But using these checks ID. 50 00:02:46,740 --> 00:02:51,900 OK so now I'm going to actually pasting some lines of code here and then I'm going to explain to you 51 00:02:51,900 --> 00:02:53,120 what's going on here. 52 00:02:53,490 --> 00:02:58,430 So as you can see here I actually pasted this switch statement inside this method. 53 00:02:58,440 --> 00:02:58,920 OK. 54 00:02:59,020 --> 00:03:03,490 So so each Ok so it's going actually to switch between the values of these checked ID. 55 00:03:03,510 --> 00:03:10,050 OK so as I said earlier this check ID is the ID of these radio buttons inside of this. 56 00:03:10,200 --> 00:03:14,530 So we can access these objects these components by using these are checked IDs. 57 00:03:14,550 --> 00:03:15,120 OK. 58 00:03:15,120 --> 00:03:17,940 So so each checked ID case. 59 00:03:17,940 --> 00:03:25,590 So in case that if the value of these fake IDs or radio button or one if the ID of these checked ID 60 00:03:25,830 --> 00:03:30,160 is you are not in one as you can see then it's going to execute this line of code here. 61 00:03:30,180 --> 00:03:31,570 Android is checked. 62 00:03:31,620 --> 00:03:32,100 OK. 63 00:03:32,250 --> 00:03:33,990 So here break. 64 00:03:34,200 --> 00:03:40,420 And if the ID is radio button two as you can see here in this content underlaid minute example the idea 65 00:03:40,440 --> 00:03:46,440 of this radio button here as you can see the idea of this radio button is actually radio button too. 66 00:03:46,470 --> 00:03:50,050 And here we have this radio button free and this radio button one. 67 00:03:50,070 --> 00:03:50,750 OK. 68 00:03:50,820 --> 00:03:55,500 So if the idea is that you get into then it's going to secure is this line of code here. 69 00:03:55,620 --> 00:03:56,250 OK. 70 00:03:56,250 --> 00:03:57,410 Our US is checked. 71 00:03:57,540 --> 00:03:58,240 OK. 72 00:03:58,260 --> 00:04:02,580 And if the idea is that you bought in free then it's going to you to execute this line of code here. 73 00:04:02,580 --> 00:04:03,160 OK. 74 00:04:03,390 --> 00:04:04,900 Windows Phone is checked. 75 00:04:05,100 --> 00:04:06,040 OK. 76 00:04:06,180 --> 00:04:07,950 So hopefully that makes sense. 77 00:04:08,070 --> 00:04:11,230 And now let's actually run our project and see what happens. 78 00:04:11,340 --> 00:04:15,240 So now as you can see our application is running on this emulator. 79 00:04:15,270 --> 00:04:18,030 And here if you scroll down here I can see these values. 80 00:04:18,060 --> 00:04:18,730 OK. 81 00:04:18,730 --> 00:04:19,420 Android or. 82 00:04:19,430 --> 00:04:19,750 Yes. 83 00:04:19,770 --> 00:04:23,830 So if I actually select this one here it says Android is checked OK. 84 00:04:24,000 --> 00:04:27,300 And if I actually select this I'll use you as is check the OK. 85 00:04:27,300 --> 00:04:31,040 And now as you can see we can only take one of these radio buttons here. 86 00:04:31,050 --> 00:04:31,590 OK. 87 00:04:31,770 --> 00:04:33,790 So here Windows Phone is checked. 88 00:04:33,990 --> 00:04:35,200 OK. 89 00:04:35,220 --> 00:04:38,330 So I think this this is enough for this application. 90 00:04:38,760 --> 00:04:43,740 And if you have any questions please post the discussion in the course and then I'll do my best to answer 91 00:04:43,800 --> 00:04:44,920 all of your questions. 92 00:04:45,090 --> 00:04:48,540 Thank you very much for watching and I'll see you in the next tutorial.
