1 00:00:00,200 --> 00:00:07,450 Hire everyone in this theater you are really going to go ahead and create our 17th Android application. 2 00:00:07,470 --> 00:00:13,670 So just click on this start in your Android studio project and here for the application name just type 3 00:00:13,670 --> 00:00:21,510 in here app 17 and you can you can actually specify the company domain package name and project location 4 00:00:21,510 --> 00:00:30,610 here and then click on next and here choose API 16 Android 4.1 Jelly Bean for minimum STK. 5 00:00:30,750 --> 00:00:34,750 Ok phone and tablet and then click on next. 6 00:00:35,280 --> 00:00:38,930 And then here choose Blanche activity next. 7 00:00:39,150 --> 00:00:39,750 OK. 8 00:00:39,990 --> 00:00:46,560 And here we can actually specify a name for the activity name lay out the name title and menu resource 9 00:00:46,560 --> 00:00:47,330 name OK. 10 00:00:47,670 --> 00:00:48,920 So click on. 11 00:00:48,930 --> 00:00:50,050 Finish. 12 00:00:50,700 --> 00:00:56,940 OK so now let's actually select this over text view here and then press on delete key on your keyboard 13 00:00:57,390 --> 00:01:02,640 and it lets you to go inside this race folder lay out an activity on the line. 14 00:01:02,650 --> 00:01:08,580 In that example and here choose these floating action button here and then press and delete key on your 15 00:01:08,580 --> 00:01:08,990 keyboard. 16 00:01:09,010 --> 00:01:13,930 OK so now let's actually go back and say this content underline man made that example. 17 00:01:14,190 --> 00:01:18,720 And here we can actually design our user interface for this application. 18 00:01:18,720 --> 00:01:19,520 OK. 19 00:01:19,650 --> 00:01:26,250 So first of all we need to actually write a linearly or 20 call into this relatively old Hiroki. 20 00:01:26,340 --> 00:01:31,510 So just put this linearly vertical at the center of this relatively out. 21 00:01:31,860 --> 00:01:32,360 OK. 22 00:01:32,490 --> 00:01:32,990 OK. 23 00:01:33,090 --> 00:01:39,100 So now let's actually track linearly out horizontally into these linearly or 20 call. 24 00:01:39,270 --> 00:01:39,980 OK. 25 00:01:40,470 --> 00:01:42,650 So now again right. 26 00:01:42,720 --> 00:01:47,770 And are there really any lay out horizontal into this linearly or horizontal here. 27 00:01:47,940 --> 00:01:48,910 OK. 28 00:01:49,100 --> 00:01:56,100 Again select this linearly horizontally here and put it inside these linearly horizontally here. 29 00:01:56,100 --> 00:01:57,000 OK. 30 00:01:57,630 --> 00:02:04,170 So as you can see here I actually made a mistake and I didn't actually put these are linearly or horizontal 31 00:02:04,190 --> 00:02:06,790 inside these linearly at horizontal here. 32 00:02:06,900 --> 00:02:13,900 And mistakenly I did put this a linear horizontal in so it is linearly earthwork the quality. 33 00:02:13,920 --> 00:02:20,800 So we just need to address this linearly horizontal and put it inside these linearly or horizontal here. 34 00:02:20,910 --> 00:02:21,600 OK. 35 00:02:22,020 --> 00:02:29,270 So as you can see here I have two linearly outs here as you can see inside these linearly or horizontal. 36 00:02:29,280 --> 00:02:29,870 OK. 37 00:02:30,240 --> 00:02:35,410 So let's actually select both of these linearly else here. 38 00:02:35,670 --> 00:02:45,360 And for the layout with assigned values 0 and for the lay out weight assign the values zero point five. 39 00:02:45,980 --> 00:02:46,510 OK. 40 00:02:46,800 --> 00:02:53,310 So here I am actually assuming that the weight of these are linearly held horizontal is for example 41 00:02:53,310 --> 00:02:54,300 number one. 42 00:02:54,570 --> 00:02:55,320 OK. 43 00:02:55,620 --> 00:03:03,530 And I am actually giving to each of these linearly else here the values zero point five for the lay 44 00:03:03,590 --> 00:03:04,250 rate. 45 00:03:04,260 --> 00:03:10,720 So each of these linearly out here are actually taking a half of the Veith of these linearly or horizontal 46 00:03:10,720 --> 00:03:11,600 loci. 47 00:03:11,640 --> 00:03:19,160 So I did actually assign the value 0 to lay out of each of these are linearly or else. 48 00:03:19,350 --> 00:03:26,640 And I actually assign the value 0.5 to the lay out rate of this linear linearly else so that these are 49 00:03:26,640 --> 00:03:27,360 linearly. 50 00:03:27,440 --> 00:03:32,680 And actually taking a half of the width of these linearly out horizontal. 51 00:03:32,700 --> 00:03:33,210 OK. 52 00:03:33,300 --> 00:03:35,340 So hopefully that makes sense. 53 00:03:35,730 --> 00:03:42,330 And now let's actually track a text view into this linearly or horizontally here. 54 00:03:42,540 --> 00:03:48,870 So just select these large takes you here and put it inside these linearly and horizontal here. 55 00:03:48,870 --> 00:03:49,740 OK. 56 00:03:50,250 --> 00:03:52,270 And double click on this text view. 57 00:03:52,290 --> 00:03:59,160 So for the text for the text just type in here rates and I don't want to give an I.D. to the States 58 00:03:59,180 --> 00:04:05,670 view because I don't want to actually interact with these component from my java code. 59 00:04:05,700 --> 00:04:06,360 OK. 60 00:04:06,630 --> 00:04:16,270 So I'll just leave the ID as default and let's actually drag and other takes you inside this search 61 00:04:16,280 --> 00:04:18,890 and linearly and hold onto it as you can see here. 62 00:04:19,080 --> 00:04:26,680 So just select these large takes here and then put it inside these linearly out horizontal here. 63 00:04:26,700 --> 00:04:27,340 OK. 64 00:04:27,630 --> 00:04:29,740 And double click on this text view. 65 00:04:30,240 --> 00:04:36,110 And for the text just typing here a number of stars. 66 00:04:36,830 --> 00:04:44,140 Ok so now let's actually do an ordinal linearly at horizontal into this linearly out vertical. 67 00:04:44,370 --> 00:04:45,110 OK. 68 00:04:45,120 --> 00:04:50,200 So as you can see here we have another linearly or horizontal inside linearly out. 69 00:04:50,310 --> 00:04:58,200 Well OK so now let's actually do a linearly or two vertical this time Enceladus this linearly of horizontal 70 00:04:59,180 --> 00:05:00,630 and again right. 71 00:05:00,640 --> 00:05:06,270 I know there are linearly out vertical in so it is linearly out horizontal OK. 72 00:05:06,360 --> 00:05:12,320 So as you can see here we have two linearly outs inside this linearly or horizontal. 73 00:05:12,390 --> 00:05:19,400 So analysis actually our select both of these are linearly outs here and for the lay out to feed the 74 00:05:19,410 --> 00:05:25,660 values 0 and for the lay out weight assigned values 0.5. 75 00:05:26,070 --> 00:05:31,260 Again I am actually assuming that the delta V of these are linearly horizontally. 76 00:05:31,260 --> 00:05:39,450 Here is actually one OK the value of the left which is linearly and horizontal is one and I am actually 77 00:05:39,620 --> 00:05:47,010 giving in and these two linearly held here are actually taking a half of the Veith of these linearly 78 00:05:47,010 --> 00:05:47,990 out horizontally. 79 00:05:48,210 --> 00:05:56,670 So I actually assign the value 0 to the outfit and I actually assigned the values 0.5 to delay of weight 80 00:05:56,730 --> 00:05:58,550 of these linearly else here. 81 00:05:58,620 --> 00:06:06,280 OK so now let's actually select a text view here large text view and put it inside these linearly or 82 00:06:06,300 --> 00:06:07,670 two vertical here. 83 00:06:07,880 --> 00:06:08,550 OK. 84 00:06:09,150 --> 00:06:12,850 So now double click on this takes you here for the text. 85 00:06:12,900 --> 00:06:19,880 Just delete the text of this text view and for the ID just type in here TXI the rates. 86 00:06:20,470 --> 00:06:21,500 OK. 87 00:06:22,140 --> 00:06:24,340 And again that's actually right. 88 00:06:24,380 --> 00:06:31,820 And other large takes you into this nearly 30 call and double click on the takes you. 89 00:06:32,430 --> 00:06:35,050 And here for the text again. 90 00:06:35,080 --> 00:06:45,330 Delete the text of this text view and for the OED just type in here Teague's the number of starts. 91 00:06:45,480 --> 00:06:46,680 OK. 92 00:06:47,250 --> 00:06:50,960 So now the design of our user interface is actually finished. 93 00:06:51,390 --> 00:06:56,620 And now we can actually go inside this main activity that you will find here and here. 94 00:06:56,790 --> 00:07:02,150 Delete these lines of code that are actually related to the options menu and here. 95 00:07:02,170 --> 00:07:06,200 Delete this block of code that is related to the floating action button. 96 00:07:06,230 --> 00:07:10,750 Ok so now we can actually put our own codes here. 97 00:07:10,800 --> 00:07:14,530 Now let's actually create two takes few objects. 98 00:07:14,550 --> 00:07:21,610 So here I just need to refer to the name of the text view class and the name of my object is DXi rates 99 00:07:22,450 --> 00:07:23,200 OK. 100 00:07:23,250 --> 00:07:29,250 Assignment operator and that I need to cast this object to a text view object find view by ID or that 101 00:07:29,280 --> 00:07:32,150 Id Dot T X the rates. 102 00:07:32,280 --> 00:07:44,160 OK semi-colon again takes you to the number of stars number of stars or the assignment operator. 103 00:07:44,250 --> 00:07:52,290 And then I need to adjust this object to take the view object find view ID on that ID Dot T x the number 104 00:07:52,290 --> 00:07:58,420 of stars OK let's actually declare two string objects. 105 00:07:58,490 --> 00:07:59,620 So strange. 106 00:07:59,960 --> 00:08:00,580 OK. 107 00:08:00,800 --> 00:08:14,340 And the name of our string object is all it takes the radius value a semicolon here I don't want to 108 00:08:14,340 --> 00:08:16,720 actually instantiate this object. 109 00:08:16,820 --> 00:08:19,770 I just declared this strange object here. 110 00:08:19,780 --> 00:08:20,590 OK. 111 00:08:21,060 --> 00:08:30,260 Again strange old tricks the number of stars. 112 00:08:31,080 --> 00:08:33,920 Well you OK. 113 00:08:34,490 --> 00:08:40,010 So now let's actually create an array of integer numbers. 114 00:08:40,040 --> 00:08:44,040 So here I want to actually create an alley of integer numbers. 115 00:08:44,090 --> 00:08:48,990 So first of all I need to specify the type of my array and. 116 00:08:49,250 --> 00:08:49,830 OK. 117 00:08:50,150 --> 00:08:53,800 And then I need to actually specify that I am going to create an array. 118 00:08:53,990 --> 00:08:58,150 So I just need to put in a pair of brackets after my type name. 119 00:08:58,250 --> 00:09:01,860 And then here I need to actually keep a name to my array. 120 00:09:01,970 --> 00:09:09,610 So the name of my AT EASE people creates OK assignments. 121 00:09:09,680 --> 00:09:17,450 Operator And then here I want to instantiate this a by giving us some values to this array. 122 00:09:17,640 --> 00:09:19,230 So here. 123 00:09:19,290 --> 00:09:23,560 So here I need to actually give a value between number 1 and the number of 5. 124 00:09:23,580 --> 00:09:24,080 OK. 125 00:09:24,360 --> 00:09:25,930 For example number one. 126 00:09:26,120 --> 00:09:26,620 OK. 127 00:09:26,700 --> 00:09:28,820 Number one for the index 0. 128 00:09:28,860 --> 00:09:35,230 Number four for the index one number free for the index to. 129 00:09:35,700 --> 00:09:51,370 And for example number five for the index free 2 5 1 3 4 5 2 4 5 8. 130 00:09:51,750 --> 00:09:55,080 And then I need to put in a semi-colon at the end of my statement.
