1 00:00:00,720 --> 00:00:06,990 So here I just need to double click on this text view and here for the text. 2 00:00:06,990 --> 00:00:12,140 Again I can just type in indices and other text. 3 00:00:12,690 --> 00:00:19,030 And for the idea I just I can't just type into the value OK and then press on into the key on your keyboard. 4 00:00:19,050 --> 00:00:22,350 So now it's actually two buttons here. 5 00:00:22,350 --> 00:00:23,960 So just select this button inside. 6 00:00:23,990 --> 00:00:29,770 We just fold it and put it at the center of this linearly Ellsworthy call. 7 00:00:30,000 --> 00:00:37,250 And for the for the lay out we assign the value match parent and double click on it. 8 00:00:37,560 --> 00:00:47,930 And for the text just typing here font one and for the ideas that I've been here between four and one 9 00:00:48,680 --> 00:00:54,560 and then press Enter key on your keyboard and now it's actually right and other button into this linearly 10 00:00:54,560 --> 00:00:58,650 alphabetical so just put it at the center of this linearly or vertical. 11 00:00:58,880 --> 00:01:05,320 And for the lay out which is the value match apparent double click on it and for the text just type 12 00:01:05,320 --> 00:01:13,250 in here for it to and for the ID just type in here between and two and then present Enter key on your 13 00:01:13,250 --> 00:01:14,080 keyboard. 14 00:01:14,420 --> 00:01:20,810 So now let's actually go back to our main activity that job right here and now let's actually instantiate 15 00:01:21,170 --> 00:01:25,270 these buttons that actually create these buttons and then instantiate them. 16 00:01:25,280 --> 00:01:34,340 So after creating these text view object here I can just type in in between font 1 assignment operator 17 00:01:34,770 --> 00:01:41,420 and in say The Apprentice's I need to cast this object to a button object find view by I. 18 00:01:41,600 --> 00:01:49,120 Excuse me find view by ID are that ID that PTEN one. 19 00:01:49,250 --> 00:01:52,310 And then I need to put a semicolon at the end of my statement. 20 00:01:52,700 --> 00:02:00,100 Again I need to create another button object PTEN font to assignment operator and that I need to cestus 21 00:02:00,170 --> 00:02:08,260 object to a button object find view by ID are that already that PTEN fun too. 22 00:02:08,480 --> 00:02:12,690 And then I need to put a semicolon at the end of my statement. 23 00:02:12,740 --> 00:02:17,270 So now let's actually make these buttons are listening to the police of the user. 24 00:02:17,360 --> 00:02:19,830 So here I can just type in between phones. 25 00:02:19,850 --> 00:02:21,340 One data set. 26 00:02:21,390 --> 00:02:23,090 Unclick listener. 27 00:02:23,930 --> 00:02:30,230 And for the argument here we need to actually pass the context so the context is this class. 28 00:02:30,230 --> 00:02:35,990 I can just type in here main activity that this and again I can't just type in between form two that 29 00:02:35,990 --> 00:02:39,980 said Uncle Clisson our main activity that this. 30 00:02:40,280 --> 00:02:45,530 And now we need to actually implement the the view that actually listen or interface. 31 00:02:45,710 --> 00:02:53,210 So here I can just click on this error here and then hold the option key hold the option and then person 32 00:02:53,630 --> 00:02:55,190 Enter key on your keyboard. 33 00:02:55,220 --> 00:03:00,290 So if you are using a Windows machine you need to hold the old key and then press on the Enter key on 34 00:03:00,290 --> 00:03:01,390 your keyboard. 35 00:03:01,730 --> 00:03:07,120 So as you can see here here it is actually recommending us some solutions. 36 00:03:07,190 --> 00:03:13,730 So here just choose this one major main activity implement Android that view that view that unclick 37 00:03:13,730 --> 00:03:14,350 listener. 38 00:03:14,480 --> 00:03:20,180 So just select this option here and here it says of any to implement this Meffert and click to just 39 00:03:20,180 --> 00:03:21,320 click OK. 40 00:03:21,800 --> 00:03:27,560 And now as you can see I have this Smurfette here inside my main activity class and here it is actually 41 00:03:27,560 --> 00:03:30,250 implementing this and click this in an interface. 42 00:03:30,470 --> 00:03:35,330 Ok so now let's actually change the name of this argument. 43 00:03:35,360 --> 00:03:37,560 That is of typed view to view. 44 00:03:38,000 --> 00:03:42,970 And now I want to actually differentiate between clicking of these buttons. 45 00:03:42,980 --> 00:03:43,250 OK. 46 00:03:43,260 --> 00:03:45,720 BT and 12:56 and BT and front too. 47 00:03:46,100 --> 00:03:53,630 So here I can just create a switch statement and here I can just type in your view that gets ID and 48 00:03:53,630 --> 00:03:56,110 then I need to open and close the switch statement. 49 00:03:56,120 --> 00:03:58,090 And he had a They've statement here case. 50 00:03:58,100 --> 00:04:05,280 So if the user clicks on this BT and found one now I can't just type in our thought Id that's PTEN font 51 00:04:05,300 --> 00:04:07,650 one colon break. 52 00:04:08,210 --> 00:04:15,460 And if the user clicks and is PTEN phone to here I can just type in art that ID that PTEN phone to call 53 00:04:15,650 --> 00:04:17,540 Colin bridge. 54 00:04:17,900 --> 00:04:23,670 So if the user clicks on this button Pythian 12:56 I want to actually use this phone here for phone 55 00:04:23,770 --> 00:04:24,640 to name one. 56 00:04:24,710 --> 00:04:29,600 And if they use that Corisande city and phone to I want to use these phone to name two. 57 00:04:29,660 --> 00:04:32,910 So here I can just typing. 58 00:04:33,030 --> 00:04:37,580 So me actually did it start this line of code here that actually that is actually setting the typeface 59 00:04:37,580 --> 00:04:39,310 of this text the value. 60 00:04:39,320 --> 00:04:46,580 So now when the user clicks on the city and one you want to actually use the default one here as you 61 00:04:46,580 --> 00:04:52,060 can see here I have this form to name one so I can just type in here takes the value. 62 00:04:52,190 --> 00:04:58,880 So as you can see here I cannot be fair to the name of this ATX the value because this takes the value 63 00:04:58,880 --> 00:05:02,950 takes view is actually created inside this uncreate method. 64 00:05:03,170 --> 00:05:07,880 And I cannot refer to the name of this the value object in sight. 65 00:05:07,880 --> 00:05:11,720 My uncle each method that is outside of this uncreate method. 66 00:05:11,720 --> 00:05:14,470 So how do I fix this problem. 67 00:05:14,570 --> 00:05:21,530 The solution for this problem is that we need to actually declare this object outside of this uncreate 68 00:05:21,680 --> 00:05:24,620 method and inside of this main activity class. 69 00:05:24,650 --> 00:05:27,930 So here I can't just delete this text view here. 70 00:05:28,310 --> 00:05:34,850 And as you can see here we have this error because it cannot understand where this takes the value is 71 00:05:34,850 --> 00:05:35,870 actually declared. 72 00:05:36,140 --> 00:05:41,260 And inside our main activity class here I can just create a text view. 73 00:05:41,890 --> 00:05:49,160 The value and I just need to put in a semicolon here so here I'm just declaring this object. 74 00:05:49,160 --> 00:05:55,510 And now inside our uncreate Mefford we are just instantiating DCX the value and insight are unclear 75 00:05:55,520 --> 00:06:02,880 uncooked Metford I can't actually refer to the name of this object takes the value that sets type face. 76 00:06:03,440 --> 00:06:06,290 And now you want to refer to the name of this form to name one. 77 00:06:06,310 --> 00:06:13,610 So because these two objects that are of type typeface for name one and Phonte to name two are actually 78 00:06:13,610 --> 00:06:15,920 declared inside this main activity class. 79 00:06:15,950 --> 00:06:16,600 OK. 80 00:06:16,640 --> 00:06:21,150 And these are actually instantiated in it is uncreate never the case here. 81 00:06:21,300 --> 00:06:23,120 Inside is unclear Smurfette. 82 00:06:23,140 --> 00:06:27,360 I can actually fair to the name of these typeface objects. 83 00:06:27,380 --> 00:06:34,800 So here I can just type in the value that set typeface for example font name one. 84 00:06:35,000 --> 00:06:43,760 And when that user clicks and this PTEN form to here I can just typing TXI the value that said typeface 85 00:06:44,840 --> 00:06:52,740 font name to and here as you can see I have this error and I forgot to put the case here Case statement. 86 00:06:52,850 --> 00:06:54,800 And now as you can see the error is gone. 87 00:06:54,800 --> 00:07:00,770 Case r that I'd eat that between two DXi value that said typeface Fontenay to break. 88 00:07:01,100 --> 00:07:06,350 And here I have this case are that ID that bitti and one takes the value that said typeface font. 89 00:07:06,350 --> 00:07:07,420 Name one page. 90 00:07:07,580 --> 00:07:12,640 So when the user clicks on this bit here and one here is going to actually use this Fontenay 1:46 the 91 00:07:12,640 --> 00:07:13,330 value. 92 00:07:13,610 --> 00:07:18,580 And when the user clicks and expedient form to button here it's going to actually use this phone. 93 00:07:18,590 --> 00:07:21,050 Named to 40 sticks the value. 94 00:07:21,170 --> 00:07:24,340 So let's let's actually run our project and see what happens. 95 00:07:24,440 --> 00:07:28,910 So now as you can see our application is running on this emulator. 96 00:07:28,910 --> 00:07:32,510 So here I just need to click on this the front one. 97 00:07:32,720 --> 00:07:35,990 And now as you can see the front of this takes is actually changed. 98 00:07:35,990 --> 00:07:37,930 So let's actually click on this one too. 99 00:07:38,270 --> 00:07:41,590 And now as you can see the font of this text is changed. 100 00:07:41,600 --> 00:07:44,790 OK font 1 and 4 2. 101 00:07:44,870 --> 00:07:46,920 So hopefully that makes sense. 102 00:07:47,480 --> 00:07:53,870 And I think that's enough for this tutorial so if you have any questions please post the discussion 103 00:07:53,870 --> 00:07:59,330 in the course and then I'll do my best to answer all of your questions. 104 00:07:59,330 --> 00:08:01,000 Thank you very much for watching. 105 00:08:01,280 --> 00:08:07,310 And another important point that I want actually mention is that a lot is that when I actually click 106 00:08:07,310 --> 00:08:08,420 on this phone to name one. 107 00:08:08,420 --> 00:08:14,180 Now as you can see the height of this text is actually changed according to the text that is inside 108 00:08:14,180 --> 00:08:15,320 of this text view. 109 00:08:15,320 --> 00:08:16,980 And if I click on his phone too. 110 00:08:17,090 --> 00:08:19,810 Now again the height of this text is changed. 111 00:08:19,910 --> 00:08:25,410 And that's because of this rap content attribute that we set for this takes. 112 00:08:25,430 --> 00:08:33,880 So if I actually select this text view here as you can see the height of this text is rap content. 113 00:08:33,920 --> 00:08:39,520 And if we actually change the slab content to for example of value for example 100. 114 00:08:39,590 --> 00:08:42,770 Now if I press an interviewee on my keyboard. 115 00:08:43,040 --> 00:08:46,260 Now let's actually on our project and see what happens. 116 00:08:46,550 --> 00:08:50,340 So now as you can see our application is running on this emulator. 117 00:08:50,510 --> 00:08:54,410 So here you can see that the height of this text view is 100. 118 00:08:54,770 --> 00:08:59,430 And we cannot see the entire text that is inside of the stakes view. 119 00:08:59,480 --> 00:09:04,630 So if you click on this one here now you can see disvalue is here. 120 00:09:04,640 --> 00:09:10,250 And if I click on this phone to here now which we can only see this this is here and another takes is 121 00:09:10,250 --> 00:09:12,970 actually hidden from us. 122 00:09:13,070 --> 00:09:15,460 So it is you can it is your option. 123 00:09:15,470 --> 00:09:21,050 It is you can actually choose what would be the value of the height of your text. 124 00:09:21,050 --> 00:09:25,950 So for example I chose one high that he had I could choose for example 500. 125 00:09:26,300 --> 00:09:28,920 So let's actually run our project again. 126 00:09:29,000 --> 00:09:36,290 So now as you can see the height of my takes view is 500 and now I can see the text of these takes few 127 00:09:36,320 --> 00:09:39,820 but I cannot see the buttons here in my layout. 128 00:09:39,980 --> 00:09:42,390 So I think the 500 is too much. 129 00:09:42,410 --> 00:09:47,690 So let's actually to change 500 to another value for example 200. 130 00:09:48,380 --> 00:09:51,410 And now let's run our project again and see what happens. 131 00:09:51,410 --> 00:09:55,130 So here you can see that our application is running on the simulator. 132 00:09:55,160 --> 00:09:58,820 So if I click on this front one here now you can see this value. 133 00:09:58,970 --> 00:10:00,890 And if I click on this I want to hear. 134 00:10:01,010 --> 00:10:02,270 Now you can see this value. 135 00:10:02,330 --> 00:10:07,060 But part of this vort here text is actually hidden from us. 136 00:10:07,070 --> 00:10:14,060 This is another text but you can actually specify the height of your text view or you can actually use 137 00:10:14,660 --> 00:10:21,050 a vertical scroll view and then put your user interface components inside that scroll view and you can 138 00:10:21,050 --> 00:10:23,740 actually customize your layouts. 139 00:10:24,240 --> 00:10:25,550 And I think that it. 140 00:10:25,580 --> 00:10:29,560 So thank you very much for watching and I'll see you in the next tutorial.
