1 00:00:00,210 --> 00:00:06,070 Hire everyone in this theater we're going to go ahead and create another Android application. 2 00:00:06,090 --> 00:00:07,230 So just click on this. 3 00:00:07,270 --> 00:00:14,580 Start in your Android studio project and for the application name just type in your app 26 and then 4 00:00:14,580 --> 00:00:22,770 click on next and here choose API 16 Android 4 point point 1 Jelly Bean for a minimum SDK and then click 5 00:00:22,770 --> 00:00:24,110 on next here. 6 00:00:24,110 --> 00:00:26,520 Choose blench activity next. 7 00:00:26,670 --> 00:00:28,120 And then we can finish. 8 00:00:28,150 --> 00:00:29,410 OK OK. 9 00:00:29,520 --> 00:00:33,170 Now let's actually select this hello world takes you here. 10 00:00:33,450 --> 00:00:38,870 And then press on delete key on your keyboard and then double click on this race for here. 11 00:00:39,030 --> 00:00:45,140 Lay out activity underline that example and then here selectees floating action butter. 12 00:00:45,270 --> 00:00:49,750 And then click on delete and then actually person delete key on your keyboard. 13 00:00:49,790 --> 00:00:55,590 OK so now let's actually go back inside this content line made that example. 14 00:00:55,620 --> 00:00:59,690 And here we are actually designed to use an interface of our application. 15 00:00:59,700 --> 00:01:07,620 So now let's actually select these linearly out vertical here and put it at the center of this relatively 16 00:01:07,620 --> 00:01:08,270 out here. 17 00:01:08,340 --> 00:01:09,010 OK. 18 00:01:09,330 --> 00:01:15,180 And then let's actually select this large takes of you here and put it at the center of this linearly 19 00:01:15,180 --> 00:01:16,790 outwards call here. 20 00:01:17,070 --> 00:01:24,210 Double click on it and for the text just type in here the initial capacity of aerialist is and then 21 00:01:24,210 --> 00:01:30,150 put a colon OK at the end of your text and then press Enter key on your keyboard. 22 00:01:30,180 --> 00:01:30,720 OK. 23 00:01:31,080 --> 00:01:38,230 So now it's actually the rack and other large text view into this linearly and vertical here and double 24 00:01:38,230 --> 00:01:45,350 click on it delete the text of this text view and for the ID just type in here takes the initial capacity 25 00:01:45,350 --> 00:01:46,220 OK. 26 00:01:47,310 --> 00:01:52,670 Initial capacity and then present Enter key on your keyboard. 27 00:01:52,980 --> 00:01:57,420 So now it's actually actually a scroll. 28 00:01:57,420 --> 00:02:00,650 You are a horizontal scroll you into this linearly alphabetical. 29 00:02:00,690 --> 00:02:05,680 Just put it at the center of this linearly out vertical. 30 00:02:06,100 --> 00:02:06,760 OK. 31 00:02:07,050 --> 00:02:14,230 And then for the layout we just assign the value wrap content here. 32 00:02:14,490 --> 00:02:16,810 And for the of height assign the value 50. 33 00:02:16,940 --> 00:02:17,810 OK. 34 00:02:18,240 --> 00:02:24,900 And then let's actually select this large takes view and put it inside this horizontal scroll view here 35 00:02:25,380 --> 00:02:28,540 and then double click on it deletes the text of the stakes. 36 00:02:28,620 --> 00:02:33,080 And for the ID just type in here takes the released values. 37 00:02:33,090 --> 00:02:33,490 OK. 38 00:02:33,540 --> 00:02:36,130 And then person enter here on your keyboard. 39 00:02:36,540 --> 00:02:44,180 So now let's actually select another large text view here and put it inside this up linearly with vertical 40 00:02:44,660 --> 00:02:46,670 A-J and double click on it. 41 00:02:46,800 --> 00:02:54,510 And for the text just type in here the capacity of at least after adding values is and put a colon at 42 00:02:54,510 --> 00:02:55,080 the end here. 43 00:02:55,080 --> 00:03:00,460 Or keep the capacity of at least after adding values is colon. 44 00:03:00,540 --> 00:03:03,040 And then press enter key on your keyboard. 45 00:03:03,330 --> 00:03:08,480 So now let's actually select another large text view and put it up below this text view here. 46 00:03:08,490 --> 00:03:11,940 And inside these are linearly out vertical at the center. 47 00:03:11,940 --> 00:03:12,790 OK. 48 00:03:12,990 --> 00:03:16,100 Double click on it deletes the text of this text view. 49 00:03:16,530 --> 00:03:28,030 And then for the IDE it takes the at least capacity after adding values. 50 00:03:28,840 --> 00:03:29,530 OK. 51 00:03:29,670 --> 00:03:32,020 And then press Enter key on your keyboard. 52 00:03:32,100 --> 00:03:41,100 OK so now let's actually go back inside this main activity that double file here and now let's actually 53 00:03:41,310 --> 00:03:45,210 delete these lines of code that are related to the menu of options button here. 54 00:03:45,270 --> 00:03:50,610 And then it is a block of code that is related to the floating action button. 55 00:03:50,610 --> 00:03:53,320 And now we can actually put our own code here. 56 00:03:53,480 --> 00:03:57,740 OK so now let's actually create some takes objects here. 57 00:03:57,900 --> 00:04:03,450 So as you can see here these are the lines of code that actually pasted here and here as you can see 58 00:04:03,450 --> 00:04:04,730 in line 19. 59 00:04:04,920 --> 00:04:11,070 I created an object from this text view class called TXI the initial capacity. 60 00:04:11,070 --> 00:04:18,090 And here I referred to this identity X the initial capacity and here as you can CTX the A-list values 61 00:04:18,450 --> 00:04:27,810 are that are the list values anti-X the array list capacity after adding values TXI the Arab List capacity 62 00:04:27,810 --> 00:04:29,290 after adding values here. 63 00:04:29,370 --> 00:04:33,270 OK so now let's actually add somewhat some lines of code here. 64 00:04:33,380 --> 00:04:34,290 OK OK. 65 00:04:34,350 --> 00:04:37,960 Now we want to actually create an array of string values. 66 00:04:37,980 --> 00:04:38,720 OK. 67 00:04:39,000 --> 00:04:45,620 So here as you can see in line 26 I created an array of string values called animals. 68 00:04:45,750 --> 00:04:49,320 But this time I actually created an array list. 69 00:04:49,380 --> 00:04:50,020 OK. 70 00:04:50,400 --> 00:04:55,980 So here I can actually tell you that this type of array is proficient. 71 00:04:56,250 --> 00:05:02,440 For the users for the programmers who actually don't know the length of their alley. 72 00:05:02,450 --> 00:05:03,090 OK. 73 00:05:03,470 --> 00:05:11,480 So here as you can see we have our A-list here and inside of these attacks I actually specified the 74 00:05:11,480 --> 00:05:13,410 type of my Arey Stream. 75 00:05:13,460 --> 00:05:16,560 And then the name of my Auret is animals. 76 00:05:16,760 --> 00:05:23,480 And then I actually instantiated this Ari while using this new keyboard Aurelia's strange Prentice's 77 00:05:23,590 --> 00:05:24,290 semi-close. 78 00:05:24,380 --> 00:05:28,440 OK this is how you create and actually really object. 79 00:05:28,450 --> 00:05:31,410 Now I'm going to actually add some values to this. 80 00:05:31,560 --> 00:05:31,960 OK. 81 00:05:32,000 --> 00:05:38,190 So first of all let me actually tell you what would be the size of this at least here. 82 00:05:38,210 --> 00:05:42,920 So now I'm going to actually output the size of this at least to the screen. 83 00:05:43,280 --> 00:05:50,330 So here I just referred to the name of this object TXI the initial capacity that said text anemones. 84 00:05:50,510 --> 00:05:54,210 So now I referred to the name of this Aurelia's object here. 85 00:05:54,320 --> 00:05:56,200 Animals that size. 86 00:05:56,390 --> 00:06:02,730 So the Smurfette this size actually turns up the size of these are here to me. 87 00:06:02,750 --> 00:06:09,030 So here I actually converted this value to a string value so that we can see this rally on the screen. 88 00:06:09,050 --> 00:06:09,660 OK. 89 00:06:09,950 --> 00:06:12,890 So let's actually on our project and see what happens. 90 00:06:12,890 --> 00:06:19,580 So here as you can see our application is running on this emulator and the initial capacity of at least 91 00:06:19,670 --> 00:06:20,790 is zero. 92 00:06:21,100 --> 00:06:21,700 OK. 93 00:06:22,010 --> 00:06:28,460 So let's go back and say this main activity the java file here and now let's actually add some values 94 00:06:28,790 --> 00:06:29,990 to these animals. 95 00:06:30,370 --> 00:06:30,950 OK. 96 00:06:31,220 --> 00:06:39,410 So here as you can see I actually added some values to these animals Auret animals that live in animals 97 00:06:39,620 --> 00:06:50,880 that had Tiger animals and chat animals that punter animals that bear animals that bird animals at FOX. 98 00:06:50,930 --> 00:06:51,490 OK. 99 00:06:51,680 --> 00:06:56,310 And this feature is adding feature is not actually available for a normal race. 100 00:06:56,330 --> 00:06:56,970 OK. 101 00:06:57,170 --> 00:07:01,290 So if you do know what would be the length of your of a. 102 00:07:01,550 --> 00:07:05,870 Use the normal rate that they actually touch you in the previous tutorials. 103 00:07:06,110 --> 00:07:12,610 But if you do not know what would be the length of your array are used this kind of art at least here. 104 00:07:12,680 --> 00:07:13,750 OK. 105 00:07:14,140 --> 00:07:20,590 And now let me actually output these values to the screen by using a for loop here. 106 00:07:20,600 --> 00:07:25,970 So now I'm going actually paste in some lines of code here and then I'll explain to you what's going 107 00:07:25,970 --> 00:07:26,330 on here. 108 00:07:26,330 --> 00:07:26,900 OK. 109 00:07:27,110 --> 00:07:32,290 So here as you can see these are the lines of code that they actually pasted here and in line first 110 00:07:32,330 --> 00:07:33,600 is forty eight. 111 00:07:33,620 --> 00:07:37,520 As you can see I actually declare a string variable here. 112 00:07:37,550 --> 00:07:41,950 And as you can see I didn't instantiate this variable yet. 113 00:07:41,990 --> 00:07:42,520 OK. 114 00:07:42,740 --> 00:07:44,680 And here I created a for loop. 115 00:07:44,720 --> 00:07:45,240 OK. 116 00:07:45,410 --> 00:07:51,110 And inside the apprentice's of this for a loop as you can see I created of our table of type integer 117 00:07:51,380 --> 00:07:55,400 index and then I assign the value 0 to this variable. 118 00:07:55,550 --> 00:08:01,790 And then here I specify the condition which determines how many times this group is going to be executed. 119 00:08:01,790 --> 00:08:08,850 So until the value of this index variable is less than the value of the size of these animals array 120 00:08:09,020 --> 00:08:11,600 as you can see this loop is going to be executed. 121 00:08:11,840 --> 00:08:18,350 And here I specify that after each execution of this for loop the value of this index value bet is going 122 00:08:18,350 --> 00:08:19,840 to be incremented by 1. 123 00:08:19,880 --> 00:08:20,560 OK. 124 00:08:20,780 --> 00:08:27,890 And here inside the curly braces of this for loop as you can see these lines of code here are in line 125 00:08:27,940 --> 00:08:30,200 40 Vonte actually instantiated. 126 00:08:30,200 --> 00:08:37,020 This all takes the at least values here and here I refer it to the name of this object to 60 at least 127 00:08:37,100 --> 00:08:39,610 values that get takes that was three. 128 00:08:39,680 --> 00:08:39,980 OK. 129 00:08:39,980 --> 00:08:43,020 And then I assign this value to this variable here. 130 00:08:43,040 --> 00:08:44,000 OK. 131 00:08:44,030 --> 00:08:50,590 And then in line of 42 as you can see I referred to the name of this object t x the at least values 132 00:08:50,600 --> 00:08:57,550 that said text all TXI the list values plus animals that get here as you can see. 133 00:08:57,560 --> 00:09:02,780 You want to actually get the value that is inside that specific index of this. 134 00:09:02,840 --> 00:09:03,370 OK. 135 00:09:03,380 --> 00:09:10,010 So for example for the first time that this loop is going to be executed the value of this index variable 136 00:09:10,010 --> 00:09:10,520 is zero. 137 00:09:10,520 --> 00:09:11,080 OK. 138 00:09:11,270 --> 00:09:15,010 So here now we have animals that get index. 139 00:09:15,050 --> 00:09:18,480 OK so now it's going actually to go inside of these animals already. 140 00:09:18,530 --> 00:09:24,650 And as you can see here this lion value here is actually at the index 0 of this tree. 141 00:09:24,860 --> 00:09:25,320 OK. 142 00:09:25,430 --> 00:09:28,040 So it's going to return this value to me. 143 00:09:28,040 --> 00:09:32,650 Animals that get our index is going to give me this value to me. 144 00:09:32,660 --> 00:09:33,180 OK. 145 00:09:33,380 --> 00:09:40,020 And here I actually putting a space here and now let's actually run our project and see what happens. 146 00:09:40,070 --> 00:09:40,550 OK. 147 00:09:40,610 --> 00:09:45,100 So here as you can see our application is running on this emulator here. 148 00:09:45,380 --> 00:09:47,380 And here we can actually see these values. 149 00:09:47,390 --> 00:09:49,680 And if they actually scroll to the left. 150 00:09:49,700 --> 00:09:54,730 So here scroll to the left as you can see we can see the other values. 151 00:09:54,740 --> 00:09:55,700 OK. 152 00:09:56,150 --> 00:10:00,800 The other values that are actually inside of these animals a ok.
