1 00:00:00,290 --> 00:00:06,190 Hi everyone in this theater are really really going to go ahead and create another Android application. 2 00:00:06,210 --> 00:00:07,300 So just click on this. 3 00:00:07,350 --> 00:00:13,740 Start in your Android studio project here and here for the name of our application just type in here 4 00:00:13,770 --> 00:00:20,630 app 51 and here are click on next and here for the minimum STK choose. 5 00:00:20,670 --> 00:00:24,040 AP is 16 Android 4.1 jelly bean. 6 00:00:24,150 --> 00:00:31,370 And then click on next and here choose empty activity next and here click on finish. 7 00:00:31,530 --> 00:00:35,340 So as you can see here now our project is actually created. 8 00:00:35,340 --> 00:00:37,200 So now let's actually double click on this. 9 00:00:37,200 --> 00:00:43,440 This folder here and then double click on the layout folder and then double click on this activity underline 10 00:00:43,480 --> 00:00:45,330 minute example here. 11 00:00:45,360 --> 00:00:48,930 So now I want to design the user interface of our application. 12 00:00:49,110 --> 00:00:54,510 So just select the hello world takes you here and then Fri-Sun delete key on your keyboard. 13 00:00:54,720 --> 00:00:59,610 So that is actually double click on this activity Underland minute example in order to make this design 14 00:00:59,640 --> 00:01:00,670 area wider. 15 00:01:01,020 --> 00:01:08,680 And now let's actually try to linearly out vertical at the center of this relatively out here and then 16 00:01:08,730 --> 00:01:11,850 let's actually find this a vertical scroll. 17 00:01:11,850 --> 00:01:13,990 Your insight is container's for that. 18 00:01:14,010 --> 00:01:21,580 So just select it and put it at the center of this linearly out vertical and then let's actually again 19 00:01:21,680 --> 00:01:26,660 right and linearly out vertical as you can see here inside this layouts folder. 20 00:01:26,780 --> 00:01:31,990 Select is linearly at Westcott and put it inside this scroll you here. 21 00:01:32,040 --> 00:01:32,590 OK. 22 00:01:32,700 --> 00:01:34,960 So just put it at the center here. 23 00:01:34,980 --> 00:01:35,730 OK. 24 00:01:36,130 --> 00:01:41,970 And now as you can see this linearly vertical is actually inside the scroll you here. 25 00:01:42,150 --> 00:01:42,850 OK. 26 00:01:43,230 --> 00:01:50,340 And now let's actually tried some text views inside this linearly out vertical. 27 00:01:50,370 --> 00:01:55,890 So Enceladus if it is for that as you can see here I have these takes two views here. 28 00:01:55,920 --> 00:02:03,180 So just select these large takes here and put it inside this linearly out vertical and here and here 29 00:02:03,210 --> 00:02:08,940 as you can see I have these properties that are related to this large text view. 30 00:02:09,030 --> 00:02:17,340 And here for the lay of gravity just select center horizontal and now as you can see our text view is 31 00:02:17,340 --> 00:02:24,960 actually centered horizontally inside this linearly or TerraCycle and for play out which is kind of 32 00:02:24,960 --> 00:02:28,980 at the end the value match pallete and here. 33 00:02:28,990 --> 00:02:35,950 Let's actually find the grip the gravity attribute that is related to the stakes because I want to center. 34 00:02:35,970 --> 00:02:38,830 This takes Enceladus takes you here. 35 00:02:38,950 --> 00:02:41,550 So I can't just find the gravity attribute here. 36 00:02:41,560 --> 00:02:47,320 So as you can see this is the this is the gravity attribute to open this great gravity attribute here. 37 00:02:47,320 --> 00:02:50,510 And just check this sent her a checkbox here. 38 00:02:50,680 --> 00:02:57,310 So now as you can see it is the taste of this takes is actually centered inside this takes you OK by 39 00:02:57,310 --> 00:03:00,210 actually manipulating this gravity attribute. 40 00:03:00,210 --> 00:03:00,910 OK. 41 00:03:01,300 --> 00:03:02,960 So hopefully that makes sense. 42 00:03:03,190 --> 00:03:07,930 And now let's actually double click and this takes here and it takes just typing here. 43 00:03:07,930 --> 00:03:13,230 This is text number one. 44 00:03:13,330 --> 00:03:17,140 And for the idea just type in here it takes the number one 45 00:03:20,130 --> 00:03:23,780 or the text number one. 46 00:03:24,550 --> 00:03:25,140 OK. 47 00:03:26,930 --> 00:03:34,040 And then person Enter key on your keyboard and then let's actually try and order a text view into this 48 00:03:34,370 --> 00:03:35,860 linearly Ellsworthy call. 49 00:03:35,870 --> 00:03:42,940 So just select this large text view here and put it inside this linearly or vertical again for the lay 50 00:03:42,940 --> 00:03:47,380 out gravity assign the values center horizontal as you can see here. 51 00:03:47,690 --> 00:03:54,760 And for the lay out which is the value match Pallant and now the second we find the gravity attribute 52 00:03:55,010 --> 00:03:57,220 as you can see here this is the gravity attribute. 53 00:03:57,410 --> 00:04:03,680 And here check the center checkbox here and now as you can see this the text of this text view is actually 54 00:04:03,680 --> 00:04:04,820 centered inside. 55 00:04:04,820 --> 00:04:08,400 This takes you and double clicking on these takes here. 56 00:04:08,510 --> 00:04:18,580 So for the text just typing here this is text number 2 and for the ID just type in here it takes the 57 00:04:19,000 --> 00:04:21,730 text number two. 58 00:04:22,510 --> 00:04:22,960 OK. 59 00:04:23,080 --> 00:04:25,760 And then press on Enter key on your keyboard. 60 00:04:26,020 --> 00:04:31,450 And again let's actually drag another takes you into this linearly outway article so just select is 61 00:04:31,450 --> 00:04:38,020 large takes you inside these widgets folder and put it inside this linearly at vertical as you can see 62 00:04:38,020 --> 00:04:38,310 here. 63 00:04:38,320 --> 00:04:44,610 Inside this componentry section here and here again let's actually assign the values center horizontal 64 00:04:44,620 --> 00:04:47,030 for the lay of gravity of this text view. 65 00:04:47,080 --> 00:04:49,740 So here this is the center hole is on top. 66 00:04:49,750 --> 00:04:57,970 I just need to select it and faultily out we assign the value match Pallant and here are for the gravity 67 00:04:58,060 --> 00:04:59,010 attribute. 68 00:04:59,110 --> 00:05:03,900 Check this center check checkbox here and then double click and this takes you here. 69 00:05:04,180 --> 00:05:06,250 And for that takes just a minute here. 70 00:05:06,250 --> 00:05:22,020 This is this is text number free and for the ideas they've been here use the text number three OK and 71 00:05:22,020 --> 00:05:24,320 then press Enter key on your keyboard. 72 00:05:24,660 --> 00:05:30,150 So now let's ask you to go inside our main activity the java file here and now I want to actually declare 73 00:05:30,480 --> 00:05:33,310 my user interface components here. 74 00:05:33,570 --> 00:05:36,720 Some objects of type using interface components. 75 00:05:36,720 --> 00:05:41,490 So as you can see here in this design area I have these takes views. 76 00:05:41,490 --> 00:05:43,340 So these are the user interface components. 77 00:05:43,350 --> 00:05:49,140 So inside our main activity that of a file you want to actually create objects of type text view in 78 00:05:49,140 --> 00:05:53,180 order to interact with these user interface components. 79 00:05:53,190 --> 00:06:03,840 So here I can't just declare a text view object takes to view the text number one semicolon text view 80 00:06:04,360 --> 00:06:08,720 takes the text number two. 81 00:06:08,730 --> 00:06:09,550 OK. 82 00:06:09,960 --> 00:06:19,770 And of the first object is going to be again after it takes you to fix the text number free and then 83 00:06:19,770 --> 00:06:22,370 put a semicolon at the end of your statement. 84 00:06:22,380 --> 00:06:29,460 So now inside our uncreate method I need to actually instantiate these objects that I actually declared 85 00:06:29,520 --> 00:06:31,540 inside our main activity class. 86 00:06:31,560 --> 00:06:36,540 So as you can see here here we are just declaring these objects we're not creating these objects. 87 00:06:36,720 --> 00:06:41,950 And here and if we actually refer to these objects anywhere in my code my eyes my eyes. 88 00:06:42,060 --> 00:06:47,880 My application is going to crash because these objects are not instantiated yet. 89 00:06:47,990 --> 00:06:53,700 OK so here I can just type anti-X the text number one assignment operator. 90 00:06:53,850 --> 00:07:00,140 And here I need to actually cast this object where it takes you object fly into view by id r that ID 91 00:07:00,210 --> 00:07:09,650 that takes the x number one semi-colon the X the takes number two assignment operator takes view find 92 00:07:09,660 --> 00:07:19,350 view by the artist Id that takes the text number two semi-colon takes the takes number of the assignment 93 00:07:19,350 --> 00:07:27,630 operator and here I need to cast this object we takes few object find view ID are that ID that takes 94 00:07:27,630 --> 00:07:32,750 the takes number feet and then put a semi-colon at the end of your statement. 95 00:07:32,760 --> 00:07:38,490 So now I want to actually create an assets folder in my project structure. 96 00:07:38,550 --> 00:07:43,830 So just click on this view here at the top tool windows and then click on project here. 97 00:07:44,310 --> 00:07:47,550 And as you can see here for this section at the top here choose Android. 98 00:07:47,550 --> 00:07:50,500 OK this is important and then select this app. 99 00:07:50,500 --> 00:07:53,330 Here this app folder right click on it. 100 00:07:53,610 --> 00:08:00,840 And then here you choose new and then choose folder and then click on these assets folder. 101 00:08:00,840 --> 00:08:01,620 OK. 102 00:08:02,010 --> 00:08:03,960 And here just don't change anything. 103 00:08:03,990 --> 00:08:05,670 And then click on finish. 104 00:08:05,790 --> 00:08:11,700 So as you can see here I have these assets folder inside my app here and right clicked on these assets 105 00:08:11,760 --> 00:08:13,120 folder new. 106 00:08:13,290 --> 00:08:17,370 And then click on Android resource directory for the name of my directory. 107 00:08:17,370 --> 00:08:20,960 I can't just type in menu underline mean. 108 00:08:21,350 --> 00:08:21,850 OK. 109 00:08:22,020 --> 00:08:29,910 And for the resource type just to just choose this menu here as you can see here and again change this 110 00:08:29,950 --> 00:08:33,560 name to just a directory name too many are made. 111 00:08:34,590 --> 00:08:36,140 And then click on OK. 112 00:08:36,360 --> 00:08:44,100 And right click on these assets folder here and then Neo and then click on directory and then for the 113 00:08:44,100 --> 00:08:48,600 name of our directives just type in here fonts and then click on OK. 114 00:08:48,810 --> 00:08:53,200 So as you can see here I have this Faunce directory inside these assets folder. 115 00:08:53,250 --> 00:08:57,850 So I have to actually put some fonts inside this Faunce fold fonts directory. 116 00:08:57,860 --> 00:09:05,040 OK so now on my desktop I have some fonts and by the way if you want to actually download some fonts 117 00:09:05,070 --> 00:09:09,010 from the Internet on your web browser you can actually use these. 118 00:09:09,010 --> 00:09:10,760 Are you Arel in your search bar. 119 00:09:10,770 --> 00:09:18,930 W w w that one thousand and one free fonts that come here you can actually choose one format and then 120 00:09:18,930 --> 00:09:23,750 download it and then you get and then you can actually use that font in your projects. 121 00:09:23,830 --> 00:09:32,400 But now on my desktop as you can see here on my desk that I have these phones here I don't know I downloaded 122 00:09:32,400 --> 00:09:34,300 these phones from the Internet. 123 00:09:34,320 --> 00:09:38,030 The first one is actually the format of the first one is that ETF. 124 00:09:38,160 --> 00:09:42,960 The second one is that what you have and the first one is also that T.F.. 125 00:09:43,080 --> 00:09:50,010 So I just need to select all of them and then right click on them and then click on copy free items 126 00:09:50,460 --> 00:09:55,200 and in my android studio I just need to select is Fornes directed here. 127 00:09:55,290 --> 00:09:59,590 Right click on it and then click on paste and then click on OK. 128 00:09:59,910 --> 00:10:05,540 So now as you can see here in my inside my phone straighted I have these phones here. 129 00:10:05,670 --> 00:10:09,920 So now let's actually run our project and see what happens.
