1 00:00:00,420 --> 00:00:05,470 So as you can see here these are the lines of code that I pasted here. 2 00:00:05,580 --> 00:00:12,570 So again we have two buttons in the preview you can see these two buttons inside these linearly or horizontal. 3 00:00:12,630 --> 00:00:18,360 And again we have these buttons with the same attributes that we have here for this first linearly or 4 00:00:18,360 --> 00:00:19,220 horizontal. 5 00:00:19,410 --> 00:00:27,110 So again the lay out which is a 0 DP The layout height is the up content delay outwait is zero point 6 00:00:27,110 --> 00:00:30,330 five and lines is number two as you can see here. 7 00:00:30,330 --> 00:00:37,590 So this means that this button can accept two lines of text and the layout margin for each of the directions 8 00:00:38,280 --> 00:00:41,670 left top right and bottom is five deep. 9 00:00:41,730 --> 00:00:44,000 And again we have another button here. 10 00:00:44,190 --> 00:00:46,520 Again the lead out is zero. 11 00:00:46,600 --> 00:00:54,710 DP and the layout height is that content the layout weight is zero point five and lines is number 2. 12 00:00:54,990 --> 00:00:57,720 And the left margin is five right. 13 00:00:57,720 --> 00:01:00,450 So we need another linearly or horizontal here. 14 00:01:00,450 --> 00:01:06,440 So after the end the stack of these linearly Olthuis until now we need to create another linearly or 15 00:01:06,480 --> 00:01:07,460 horizontal here. 16 00:01:07,560 --> 00:01:14,760 So just typing in here linearly out and for the layout we assign the value match parent and for the 17 00:01:14,840 --> 00:01:18,480 layout height assign the value of that content. 18 00:01:19,000 --> 00:01:22,670 And now let's actually specify the orientation. 19 00:01:22,890 --> 00:01:32,640 So the orientation is horizontal and let's specify the ID and the ID is going to be first row filled 20 00:01:32,870 --> 00:01:37,670 a row linear layout. 21 00:01:37,950 --> 00:01:38,500 Right. 22 00:01:38,710 --> 00:01:46,610 But again we didn't specify here that we want to create an ID soap at sign Plus Id slash. 23 00:01:46,810 --> 00:01:52,450 And this is going to be the ID first row linearly out and now inside Enceladus linearly out here we 24 00:01:52,450 --> 00:01:58,320 just need to put two more buttons here so we can actually copy these buttons here as you can see. 25 00:01:58,570 --> 00:02:00,940 I can copy these buttons here and put them here. 26 00:02:00,950 --> 00:02:03,150 Inside is linearly out here. 27 00:02:03,430 --> 00:02:09,280 So as you can see here these are the lines of code that I put in say these ferde rolling out as you 28 00:02:09,280 --> 00:02:10,060 can see here. 29 00:02:10,180 --> 00:02:16,360 So again we have the same attributes play out with is zero the layout height is the content lay out 30 00:02:16,360 --> 00:02:21,360 of it is 0.5 lines and number two and lay out margin is 5 DP. 31 00:02:21,370 --> 00:02:27,730 And again we have another another button here which is that the layout is zero DP The layout height 32 00:02:27,730 --> 00:02:31,920 is Rabbe content the layout of it is 0.5 lines. 33 00:02:31,930 --> 00:02:35,400 Number two and the layout margin is five DP Right. 34 00:02:35,440 --> 00:02:37,500 So hopefully that makes sense. 35 00:02:37,510 --> 00:02:42,160 So now after the end in touch of this linearly out horizontal here. 36 00:02:42,260 --> 00:02:45,040 Now I want to add some lines of code here. 37 00:02:45,040 --> 00:02:50,480 I'm going to paste in some lines of code here and then I'm going to explain to you what's going on here. 38 00:02:50,500 --> 00:02:55,250 So as you can see here these are the lines of code that I pasted here. 39 00:02:55,270 --> 00:03:02,350 So if we have a text view right and lay out which is that content the layout height is that content. 40 00:03:02,440 --> 00:03:06,250 And here we have a new attribute text appearance. 41 00:03:06,250 --> 00:03:06,850 OK. 42 00:03:07,300 --> 00:03:11,170 So now I have to specify the appearance of my text view. 43 00:03:11,320 --> 00:03:13,140 So I put a question mark here. 44 00:03:13,180 --> 00:03:13,690 OK. 45 00:03:13,900 --> 00:03:16,280 Question mark and throw it colon. 46 00:03:16,400 --> 00:03:19,080 83 R which stands for attributes. 47 00:03:19,120 --> 00:03:19,780 OK. 48 00:03:19,870 --> 00:03:23,450 Slash and now I can specify the appearance of my tastes. 49 00:03:23,590 --> 00:03:24,520 So we have taste. 50 00:03:24,520 --> 00:03:25,750 Appearance Large. 51 00:03:26,050 --> 00:03:27,130 We have taste. 52 00:03:27,130 --> 00:03:28,910 Appearance small. 53 00:03:29,560 --> 00:03:32,050 And we have also taste appearance. 54 00:03:32,050 --> 00:03:32,770 Medium. 55 00:03:33,000 --> 00:03:33,670 OK. 56 00:03:34,090 --> 00:03:37,300 So for our application we choose text. 57 00:03:37,300 --> 00:03:39,230 Appearance Large. 58 00:03:40,120 --> 00:03:45,070 And as you can see here this means that it's going to actually make our taste feel a little bit larger 59 00:03:45,970 --> 00:03:48,470 and we have this taste attribute. 60 00:03:48,700 --> 00:03:54,350 And now as you can see here we are referring to our strange resource inside this inside this thing that 61 00:03:54,350 --> 00:03:55,000 they smell. 62 00:03:55,150 --> 00:03:58,470 So now let's actually open our project structure. 63 00:03:58,600 --> 00:04:04,780 So just click on the view here at the top tool windows and we can project and now double click on this 64 00:04:04,840 --> 00:04:10,870 app here and then double click on this race folder and here double click on these values here and now 65 00:04:11,110 --> 00:04:12,820 inside this as you can see here. 66 00:04:12,830 --> 00:04:15,090 So these values folders we have this file here. 67 00:04:15,100 --> 00:04:17,930 This is a modified strings that ASML right. 68 00:04:18,070 --> 00:04:22,400 So just double click this file here and now as you can see we have this file here. 69 00:04:22,570 --> 00:04:26,170 So now inside this file you have substring resources. 70 00:04:26,200 --> 00:04:31,730 The first one is the name of our application string named app underlined name which is this name animal 71 00:04:31,760 --> 00:04:38,000 quis and we have this name which is actions the settings for the Settings button. 72 00:04:38,450 --> 00:04:41,380 And now I want to add other resources here. 73 00:04:41,500 --> 00:04:45,030 So let's go back to our fragment underline minute example here. 74 00:04:45,160 --> 00:04:50,770 As you can see I refer to this string resource here at science 3 inch slash question text and as you 75 00:04:50,770 --> 00:04:54,870 can see here our project does not recognize this value here right. 76 00:04:54,880 --> 00:04:56,470 Question underlying text. 77 00:04:56,470 --> 00:05:00,700 So now let's actually create our string source with this name here. 78 00:05:00,700 --> 00:05:05,630 So let's go inside the strings that gets them in here and then open attack streams. 79 00:05:06,070 --> 00:05:11,520 And the name is going to be question underlined text and then and the tag as you can see here. 80 00:05:11,650 --> 00:05:20,120 Close the tile here by by putting this piece of code here and now inside this string here inside the 81 00:05:20,130 --> 00:05:21,130 string tag. 82 00:05:21,310 --> 00:05:23,120 I can add my value here. 83 00:05:23,170 --> 00:05:33,610 So now I can't just type indices animal per cent one dollar sign. 84 00:05:33,630 --> 00:05:40,230 D of percent to dollar sign the. 85 00:05:40,290 --> 00:05:42,150 So now what does this mean. 86 00:05:42,180 --> 00:05:50,840 As you can see it says this is animal per cent one dollar Sainty of per cent to Dollar Signs. 87 00:05:51,000 --> 00:05:57,720 So this one as you can see here per cent one dollar sign D is actually an integer value is going to 88 00:05:57,720 --> 00:05:57,950 be. 89 00:05:57,990 --> 00:06:05,170 This is going to be an integer argument actually we have an integer argument as you can see here D right. 90 00:06:05,250 --> 00:06:12,630 So here as you can see because we need to actually provide this format here per cent one dollar sign. 91 00:06:12,630 --> 00:06:14,220 So what is this one here. 92 00:06:14,220 --> 00:06:18,130 This one is actually means that this is actually the first argument. 93 00:06:18,270 --> 00:06:18,830 Right. 94 00:06:18,870 --> 00:06:23,250 And this number two here means this is going to be the second argument. 95 00:06:23,250 --> 00:06:23,720 Right. 96 00:06:23,820 --> 00:06:30,900 So we need to put this format here in order to specify that that this is going to be our first argument 97 00:06:30,950 --> 00:06:33,000 which is going to be of type integer. 98 00:06:33,000 --> 00:06:33,450 Right. 99 00:06:33,480 --> 00:06:36,750 So now let me show you are the emulator here. 100 00:06:36,750 --> 00:06:39,280 Our application is running on this emulator here right. 101 00:06:39,330 --> 00:06:42,460 So now you can see that it says this is animal 1. 102 00:06:42,510 --> 00:06:45,050 So as you can see here our crew is just started. 103 00:06:45,330 --> 00:06:47,530 And this is animal one of 10. 104 00:06:47,550 --> 00:06:54,350 So we have 10 animals 10 questions as you can see here and now this is going to be the first one. 105 00:06:54,600 --> 00:06:55,170 Right. 106 00:06:55,170 --> 00:06:57,600 So as you can see the first one is number one here right. 107 00:06:57,630 --> 00:06:59,080 And the second one is number 10. 108 00:06:59,220 --> 00:07:06,780 So here we are actually code in our application when we are actually providing the logic our application 109 00:07:06,810 --> 00:07:12,140 of for our application in inside the main activity of a file or other dhaba files. 110 00:07:12,150 --> 00:07:15,870 I'll teach you that what is going to be the use of this format here. 111 00:07:15,870 --> 00:07:16,130 OK. 112 00:07:16,140 --> 00:07:19,240 Later you will understand how this format here works. 113 00:07:19,350 --> 00:07:25,020 OK for now just put this here and for now just understand that here this present one dollar sign means 114 00:07:25,290 --> 00:07:28,950 that this is going to be our first argument which is going to be off the integer. 115 00:07:29,310 --> 00:07:35,100 And here this person's two dollar sign D means that the this is going to be our second argument which 116 00:07:35,100 --> 00:07:36,570 is going to be of type integer. 117 00:07:36,720 --> 00:07:37,410 Right. 118 00:07:37,740 --> 00:07:39,900 So hopefully that makes sense. 119 00:07:39,900 --> 00:07:44,290 So now let's actually go inside a fragment underlying minute that example here. 120 00:07:44,490 --> 00:07:45,660 And as you can see here. 121 00:07:45,680 --> 00:07:47,910 So as you can see the error is gone here. 122 00:07:47,910 --> 00:07:53,450 So question underlying text and here I provided an I.D. for this text view. 123 00:07:53,640 --> 00:08:01,110 So the IDs question number takes you right as you can see here we can actually change this ID for example 124 00:08:01,110 --> 00:08:08,700 to TXI the question number right. 125 00:08:09,110 --> 00:08:10,090 This is very good. 126 00:08:10,200 --> 00:08:17,270 The question number and they lay out gravity as you can see here it says Center horizontal. 127 00:08:17,270 --> 00:08:18,010 Right. 128 00:08:18,020 --> 00:08:24,920 So this lay out gravity is going to specify what it's going to be the position of this takes you according 129 00:08:24,920 --> 00:08:26,120 to its parent. 130 00:08:26,180 --> 00:08:26,610 Right. 131 00:08:26,630 --> 00:08:29,020 So the parent of this textbook is this linearly. 132 00:08:29,060 --> 00:08:29,800 Right. 133 00:08:29,810 --> 00:08:32,610 So here it says Center horizontal. 134 00:08:32,630 --> 00:08:38,930 So here this can actually put this takes you Center horizontally inside this linear layout as you can 135 00:08:38,930 --> 00:08:39,800 see here. 136 00:08:40,310 --> 00:08:44,340 So you already know about Lyell's gravity's anti-gravity attribute. 137 00:08:44,480 --> 00:08:50,180 And as you can see we have this lay out marching but him as you can see here you provided a margin bottom 138 00:08:50,180 --> 00:08:58,960 here and now again we need to provide a resource here so let's actually open our project structure so 139 00:08:59,290 --> 00:09:06,420 click on this view here at the top tool windows and then project and then as you can see Enceladus values 140 00:09:06,420 --> 00:09:07,000 fall there. 141 00:09:07,160 --> 00:09:13,100 We have these demons that examined here to just double click on it here and now inside these resources 142 00:09:13,100 --> 00:09:13,760 tagged. 143 00:09:13,820 --> 00:09:20,540 Now we need to provide another dimension here so just to just open attach here and type in deman and 144 00:09:20,540 --> 00:09:24,220 the name is going to be Margene underlined value 145 00:09:27,460 --> 00:09:32,120 and then just close this tag and just provide a value in nine. 146 00:09:32,140 --> 00:09:34,800 DP OK. 147 00:09:34,870 --> 00:09:39,880 Now let's actually go back into our fragment underlayment and examine here and now you can see here 148 00:09:39,880 --> 00:09:41,050 the error is gone. 149 00:09:41,050 --> 00:09:45,880 So now let me double click on this fragment underline militarism and tab here in order to make this 150 00:09:45,880 --> 00:09:47,610 area wider. 151 00:09:47,740 --> 00:09:50,890 And now just a click on this preview here at the right hand side. 152 00:09:51,000 --> 00:09:57,000 And now you can see that you've got free rows with actually buttons inside them. 153 00:09:57,040 --> 00:09:59,710 And as you can see we have also this takes you here right. 154 00:09:59,950 --> 00:10:06,880 So now as you can see here the margin button is much in value which we provided here in say the statements 155 00:10:06,880 --> 00:10:07,650 that they examined here. 156 00:10:07,660 --> 00:10:09,030 As you can see 90. 157 00:10:09,550 --> 00:10:14,460 And now we have also the text color attribute which is actually the value. 158 00:10:14,520 --> 00:10:19,400 White right hash that f f f means white as you can see here. 159 00:10:19,420 --> 00:10:25,390 So now we can actually change this value for example to another value but let's actually change the 160 00:10:25,390 --> 00:10:27,630 background color of this linear layout. 161 00:10:27,640 --> 00:10:30,190 So let's just scroll to the top here. 162 00:10:30,250 --> 00:10:32,300 And as you can see here these are linearly out. 163 00:10:32,350 --> 00:10:35,580 So now I want to add another attribute to this linearly or. 164 00:10:35,600 --> 00:10:37,810 So just type in here Paglen don't. 165 00:10:38,110 --> 00:10:42,810 And as you can see here I just select Ispahan on attributes and now I can't just type in hash tag. 166 00:10:42,920 --> 00:10:44,280 Zero zero zero. 167 00:10:44,620 --> 00:10:49,170 And now as you can see here the background color of my linearly out is now black. 168 00:10:49,300 --> 00:10:51,070 And now I can see this text here. 169 00:10:51,070 --> 00:10:56,330 This is animal per cent one dollar Sainty of person two dollar sign. 170 00:10:56,440 --> 00:10:57,250 Right. 171 00:10:57,310 --> 00:10:59,840 So now scroll down here. 172 00:11:00,220 --> 00:11:02,510 And as you can see here these are tasteful here. 173 00:11:02,530 --> 00:11:03,370 Right. 174 00:11:03,370 --> 00:11:09,370 So now we're going to actually paste in some more lines of code here and then I'm going to explain to 175 00:11:09,370 --> 00:11:10,870 you what's going on here.
