1 00:00:00,760 --> 00:00:06,600 So this is the effort that we needed to actually override inside of this main activity class. 2 00:00:06,600 --> 00:00:06,870 OK. 3 00:00:06,890 --> 00:00:11,440 OK because you are actually implementing this on item calculus in an interface. 4 00:00:11,460 --> 00:00:17,550 So inside of the Smurfette of we're going to actually put in our own implementations and decide if it 5 00:00:17,550 --> 00:00:23,400 is going to be called every time the user clicks on one of these items inside of this list. 6 00:00:23,460 --> 00:00:24,470 As you can see here. 7 00:00:24,480 --> 00:00:24,950 OK. 8 00:00:25,050 --> 00:00:31,110 So now inside of this method as you can see here let's actually create a string object a key strength 9 00:00:31,680 --> 00:00:34,580 and the name of this object is item value. 10 00:00:34,590 --> 00:00:39,780 So just type in here item value assignment operator. 11 00:00:39,930 --> 00:00:44,340 So now I want to actually get the values that are inside of the list view. 12 00:00:44,340 --> 00:00:48,960 For example the value that is inside of this item is Android developer of course. 13 00:00:48,960 --> 00:00:49,390 OK. 14 00:00:49,500 --> 00:00:51,000 So in order to get this value. 15 00:00:51,000 --> 00:00:54,290 First of all I need to refer to this list view. 16 00:00:54,300 --> 00:00:54,810 OK. 17 00:00:54,930 --> 00:01:01,350 So this we at least view is actually given to us as an argument as you can see here this patent argument 18 00:01:01,620 --> 00:01:04,590 is actually does list view here as you can see here. 19 00:01:04,680 --> 00:01:06,660 This is of type after view here. 20 00:01:06,660 --> 00:01:07,350 OK. 21 00:01:07,770 --> 00:01:10,110 So this parent argument is this this view. 22 00:01:10,230 --> 00:01:14,580 So I can just first of all refer to then to this list you just parent. 23 00:01:14,750 --> 00:01:15,210 OK. 24 00:01:15,360 --> 00:01:16,980 So this is our argument. 25 00:01:17,040 --> 00:01:17,410 OK. 26 00:01:17,460 --> 00:01:21,360 So now I can actually call a method on this parent here. 27 00:01:21,360 --> 00:01:21,770 OK. 28 00:01:21,810 --> 00:01:27,840 So parent that gets item at the position. 29 00:01:27,840 --> 00:01:34,400 So now we want to actually get the item add up at a specific position inside of this list. 30 00:01:34,410 --> 00:01:34,890 OK. 31 00:01:35,040 --> 00:01:40,670 So for example this item is actually the position 0 this item is at position 1. 32 00:01:40,680 --> 00:01:47,100 This item is a position too and this item is position free and this item is that position for. 33 00:01:47,280 --> 00:01:50,790 So here we want to actually get the item at a specific position. 34 00:01:50,790 --> 00:01:56,900 So we actually also have this position as an argument or to dismiss it as you can see here. 35 00:01:56,940 --> 00:02:03,590 So we have the item that is actually the inside of this specific position inside of this list. 36 00:02:03,660 --> 00:02:04,140 OK. 37 00:02:04,230 --> 00:02:09,710 So if you have that value here as you can see as an argument called position OK. 38 00:02:09,870 --> 00:02:12,750 So I can just put that value here position. 39 00:02:13,280 --> 00:02:14,070 OK. 40 00:02:14,290 --> 00:02:18,970 And now let's actually call them if it is trained on this method. 41 00:02:19,050 --> 00:02:21,750 So it can actually convert that value to a string value. 42 00:02:21,870 --> 00:02:26,440 And then we can actually assign that value to the item value string object. 43 00:02:26,480 --> 00:02:28,350 OK so let me explain again. 44 00:02:28,350 --> 00:02:31,240 First of all with the fed through the patent argument. 45 00:02:31,260 --> 00:02:33,460 So this patent argument is this this view. 46 00:02:33,530 --> 00:02:34,150 OK. 47 00:02:34,320 --> 00:02:34,840 And we are. 48 00:02:34,890 --> 00:02:41,130 You are actually calling MF at on this argument get item at position so it can actually get a specific 49 00:02:41,190 --> 00:02:44,510 item inside of this specific position inside of this list. 50 00:02:44,520 --> 00:02:45,180 This you. 51 00:02:45,210 --> 00:02:50,400 OK so here we need to actually assign an argument to the Smurfette. 52 00:02:50,400 --> 00:02:53,640 So it's going actually asked us which identity you want. 53 00:02:53,640 --> 00:02:59,710 So we want this specific item that is inside of this specific position that is inside of this area. 54 00:02:59,850 --> 00:03:04,420 So we have that position as an argument to this click on item please. 55 00:03:04,520 --> 00:03:04,950 OK. 56 00:03:05,040 --> 00:03:08,580 So position so it get item at position position. 57 00:03:08,740 --> 00:03:09,330 Okay. 58 00:03:09,680 --> 00:03:10,550 Datastream. 59 00:03:10,830 --> 00:03:11,420 OK. 60 00:03:11,700 --> 00:03:17,630 So now let's actually create a tossed object so TOSed that makes text. 61 00:03:17,880 --> 00:03:21,830 And here we need to actually specify our free arguments to this. 62 00:03:21,830 --> 00:03:22,470 Our method here. 63 00:03:22,470 --> 00:03:24,670 First of all we need to specify the context. 64 00:03:24,810 --> 00:03:29,540 So the context is diskless main activity that this comma. 65 00:03:29,970 --> 00:03:36,180 And here we need to actually put in the value the text that we want to show the user whenever the user 66 00:03:36,180 --> 00:03:37,940 clicks on one of these items here. 67 00:03:37,980 --> 00:03:38,630 OK. 68 00:03:38,760 --> 00:03:42,010 So I can just referred to the name of this item value here. 69 00:03:42,200 --> 00:03:45,210 Okay item value karma. 70 00:03:45,960 --> 00:03:54,450 And then we need to actually specify the duration of the time that this message is going to be shown 71 00:03:54,450 --> 00:03:54,960 to the user. 72 00:03:54,990 --> 00:04:03,780 OK so now again just typing are toast that lenth short. 73 00:04:04,200 --> 00:04:07,470 And he had to actually call the show method undismayed. 74 00:04:07,500 --> 00:04:10,530 In order to show this value to the user. 75 00:04:10,580 --> 00:04:15,210 OK so now let's actually run our project and see what happens. 76 00:04:15,210 --> 00:04:20,410 So as you can see here now our application is actually running on the emulator here. 77 00:04:20,490 --> 00:04:25,030 And let's actually click on one of these items inside of this list for you. 78 00:04:25,080 --> 00:04:28,380 So as you can see here it says objective Seitel will appear of course. 79 00:04:28,380 --> 00:04:36,510 So here I can just click on this item here are U.S. developer of course here Android developers of course. 80 00:04:36,580 --> 00:04:44,430 OK so now let's actually increase the size of these values of these items inside of this list view. 81 00:04:44,430 --> 00:04:50,010 So let's actually go back and say this content underline in that example and we can either put this 82 00:04:50,100 --> 00:04:57,960 attribute here text size here for example or can just type in text size and then present Enter key on 83 00:04:57,960 --> 00:05:06,850 your keyboard and here inside of these double quotes I can put in a value for example number 70 of DP. 84 00:05:07,210 --> 00:05:07,760 OK. 85 00:05:07,900 --> 00:05:10,160 Or I can just put in espie OK. 86 00:05:10,210 --> 00:05:12,970 Espies stands for screen pixels. 87 00:05:12,970 --> 00:05:16,050 So for the size of your text it's better to use s.p. 88 00:05:16,050 --> 00:05:16,440 OK. 89 00:05:16,480 --> 00:05:21,340 And then let's actually go back and say it is a design tab here as you can see by clear chance here 90 00:05:21,820 --> 00:05:25,510 and now I can actually select this text view here and I can. 91 00:05:25,630 --> 00:05:31,320 And we can actually as you can see the size of this text size is 70 s.p. 92 00:05:31,440 --> 00:05:32,270 OK. 93 00:05:32,590 --> 00:05:38,230 We can actually change these attributes the values of these attributes here inside of these properties 94 00:05:38,530 --> 00:05:43,270 or we can actually change those values inside of these takes that up and here inside of it. 95 00:05:43,460 --> 00:05:44,610 This takes you here. 96 00:05:44,620 --> 00:05:45,180 OK. 97 00:05:45,370 --> 00:05:48,670 So let's actually run our project and see what happens. 98 00:05:48,670 --> 00:05:56,020 So now as you can see our application is on the simulator and we can see that the size of these of these 99 00:05:56,020 --> 00:06:01,190 items as you can see of these are values that are inside of this list which is actually much larger. 100 00:06:01,240 --> 00:06:01,520 OK. 101 00:06:01,540 --> 00:06:08,080 Android developer of course as you can see here are iOS developers of course and we can see and we can 102 00:06:08,080 --> 00:06:13,410 actually scroll here in order to see the other values inside of this list. 103 00:06:13,420 --> 00:06:14,800 OK. 104 00:06:14,830 --> 00:06:19,660 So let's actually change the color of these text views. 105 00:06:19,680 --> 00:06:19,990 OK. 106 00:06:19,990 --> 00:06:22,540 Change the color of these items. 107 00:06:22,600 --> 00:06:27,580 So let's actually go back and say this content underline means that examine and here inside of this 108 00:06:27,580 --> 00:06:28,410 takes me a tap. 109 00:06:28,410 --> 00:06:34,530 I can't just typing text color and then press Enter key on your keyboard. 110 00:06:34,880 --> 00:06:41,610 And here let's actually we can actually put in an orgy because the inside of these double quotes. 111 00:06:41,610 --> 00:06:46,810 And now I can actually put a hash tag here and then I can paste that value here. 112 00:06:46,810 --> 00:06:47,380 OK. 113 00:06:47,770 --> 00:06:50,770 So now let's actually do on our project and see what happens. 114 00:06:50,770 --> 00:06:55,190 So as you can see here our application is running on this emulator here. 115 00:06:55,390 --> 00:06:59,080 And as you can see we have these values inside of this list OK. 116 00:06:59,140 --> 00:07:00,650 Android developer of course. 117 00:07:00,760 --> 00:07:05,470 And as you can see the color of these values is actually changed. 118 00:07:05,470 --> 00:07:05,890 OK. 119 00:07:05,980 --> 00:07:09,690 And by the way if you want to actually get these are G-B colors. 120 00:07:09,730 --> 00:07:10,200 OK. 121 00:07:10,330 --> 00:07:14,410 There is a Web site that is called ropy tables that come here. 122 00:07:14,470 --> 00:07:20,810 Slash VEP slash color slash R.G. be underlined colors that HVM you can actually put this you are in 123 00:07:20,850 --> 00:07:23,710 your web browser and you will be guided to this page here. 124 00:07:23,710 --> 00:07:24,210 OK. 125 00:07:24,370 --> 00:07:26,820 And here you can actually choose one of these colors. 126 00:07:26,830 --> 00:07:34,030 Ok for example this color or this color as you can see here and you need to actually copy this a hex 127 00:07:34,030 --> 00:07:35,910 value as you can see here. 128 00:07:36,190 --> 00:07:39,550 And then you can you can actually put that value inside of these double quotes. 129 00:07:39,570 --> 00:07:44,670 OK first you need to put a hash tag and then you need to put that hex value here. 130 00:07:44,700 --> 00:07:50,190 OK so now let's actually do an art project and see what happens. 131 00:07:50,200 --> 00:07:55,900 So as you can see here and our application is running on this emulator and you can see that the color 132 00:07:55,900 --> 00:07:58,160 of these values is actually changed. 133 00:07:58,180 --> 00:07:59,290 OK. 134 00:07:59,290 --> 00:08:01,810 So I think that's enough for this story. 135 00:08:02,020 --> 00:08:07,480 And if you have any questions please post the discussion in the course and then I'll do my best to answer 136 00:08:07,510 --> 00:08:08,730 all of your questions. 137 00:08:08,860 --> 00:08:12,600 Thank you very much for watching and I'll see you in the next tutorial.
