1 00:00:00,290 --> 00:00:06,490 Hire everyone in this theater are really really going to go ahead and create AR15 Android application. 2 00:00:06,600 --> 00:00:12,090 So just click on this art start a new Android studio project and then for the name of our application 3 00:00:12,090 --> 00:00:19,170 name just type in here app 15 and you can actually specify the company domain package name and project 4 00:00:19,170 --> 00:00:26,300 location and then click on next and then choose if you are 16 Android 4.1 Jelly Bean for your minimums. 5 00:00:26,340 --> 00:00:26,800 OK. 6 00:00:26,910 --> 00:00:30,640 And then click on next Blache activity next. 7 00:00:30,990 --> 00:00:35,100 And then here you can actually specify a name for your activity name. 8 00:00:35,100 --> 00:00:42,210 Lay out the name and the title main activity and for the minute your resource name don't change any 9 00:00:42,210 --> 00:00:45,020 of these values and then click on finish. 10 00:00:45,170 --> 00:00:45,730 OK. 11 00:00:45,780 --> 00:00:51,420 Now let's actually delete this hello world text view and then double click on the rest folder. 12 00:00:51,420 --> 00:00:57,150 Lay out activity main and here select this floating action button and then press and delete key on your 13 00:00:57,150 --> 00:00:57,520 keyboard. 14 00:00:57,540 --> 00:00:58,330 OK. 15 00:00:58,350 --> 00:01:03,390 So let's actually go back and say this content underlined minute example and then now we want to actually 16 00:01:03,390 --> 00:01:05,650 design our user interface here. 17 00:01:05,970 --> 00:01:06,930 OK everyone. 18 00:01:06,930 --> 00:01:12,080 Now let's actually drag a linearly out vertical into this linearly out horizontal. 19 00:01:12,180 --> 00:01:18,410 So just put this linearly outward to ticket at the center of this relatively out of as you can see here. 20 00:01:18,540 --> 00:01:24,600 Now are linearly alphabetical is actually here at the center of this relatively out and the then is 21 00:01:24,600 --> 00:01:30,360 actually right or linearly and horizontal into these linear left vertical OK. 22 00:01:30,390 --> 00:01:35,300 And first of all it's actually a drag or takes you into this linearly or horizontal. 23 00:01:35,490 --> 00:01:42,710 So just select this large text view and then put it inside of these linearly and horizontal double click 24 00:01:42,710 --> 00:01:43,970 on this low stakes view. 25 00:01:44,180 --> 00:01:45,900 Is the text of this text view. 26 00:01:46,170 --> 00:01:50,400 And for the ID just type in here takes the five stars. 27 00:01:50,400 --> 00:01:51,580 Student Okay. 28 00:01:52,360 --> 00:01:54,990 And then a person and the key on your keyboard. 29 00:01:55,630 --> 00:02:00,600 And it's actually the right rating board into these linearly or horizontal. 30 00:02:00,750 --> 00:02:05,660 OK so just put it here and then double click on this rating bar here. 31 00:02:05,780 --> 00:02:11,850 And for the ID just type in here are Tibe five stars. 32 00:02:11,860 --> 00:02:13,720 Student Okay. 33 00:02:13,960 --> 00:02:18,670 And then it's actually a select these linearly or horizontal. 34 00:02:18,790 --> 00:02:25,390 And now let's actually select select this linearly horizontal and then actually find the lay of gravity 35 00:02:25,390 --> 00:02:30,760 as you can see if we have an area of gravity here and we have a gravity attribute here. 36 00:02:30,760 --> 00:02:31,150 OK. 37 00:02:31,300 --> 00:02:33,780 So let's actually find the gravity attribute. 38 00:02:33,880 --> 00:02:39,610 As you can see here and for the center horizontal that's actually select this tick box here that says 39 00:02:39,850 --> 00:02:41,470 Center horizontal OK. 40 00:02:41,710 --> 00:02:47,740 And then architecturally select these are large takes you here and essentially find the layout Margene 41 00:02:47,800 --> 00:02:52,030 as you can see this is the layout Margene that is actually related to this fixed view. 42 00:02:52,070 --> 00:02:56,170 So it opened on margin by clicking on this little triangle here. 43 00:02:56,350 --> 00:03:03,790 And for the right Margene a sign of value for example Number 10 for example Number 10 or number 20. 44 00:03:04,230 --> 00:03:05,070 OK. 45 00:03:05,560 --> 00:03:12,900 So again it's actually drag a linearly out horizontal into this linearly alphabetical and actually drag 46 00:03:12,960 --> 00:03:15,890 a rating board into this linearly and horizontal. 47 00:03:15,970 --> 00:03:20,330 Let's actually drag and other large takes you into this linearly out horizontal. 48 00:03:20,590 --> 00:03:26,390 So just select this large text and then put it inside this linearly and horizontal here. 49 00:03:26,530 --> 00:03:30,990 And as you can see here are this large takes you position on the right hand side of this. 50 00:03:31,240 --> 00:03:31,930 Right. 51 00:03:32,140 --> 00:03:39,660 But once this takes you to be at the at the left hand side of this rating but so just drag this takes 52 00:03:39,660 --> 00:03:43,390 you and put it in before this rating bar here. 53 00:03:43,750 --> 00:03:44,160 OK. 54 00:03:44,290 --> 00:03:49,140 So now as you can see this text is actually at the left hand side of this writing bar. 55 00:03:49,480 --> 00:03:53,950 So just double click on this large text view for the text just delete the text. 56 00:03:53,950 --> 00:03:54,770 This takes you. 57 00:03:54,970 --> 00:03:56,610 And the idea just typing here. 58 00:03:56,610 --> 00:03:59,350 T XTi for starters 59 00:04:01,960 --> 00:04:10,630 student OK and then person Enter key on your keyboard and let's actually select this linearly and horizontal 60 00:04:10,990 --> 00:04:18,370 and for the gravity as you can see here let's actually find the gravity attributes and selects this 61 00:04:18,490 --> 00:04:21,540 checkbox here that says Center underline horizontal OK. 62 00:04:21,640 --> 00:04:27,340 And then secondly to select this text view and find the left margin as you can see this is the left 63 00:04:27,340 --> 00:04:29,790 margin and the margin right. 64 00:04:29,830 --> 00:04:31,280 Enter the rad U-20. 65 00:04:31,300 --> 00:04:32,060 OK. 66 00:04:32,080 --> 00:04:38,560 So as you can see here we didn't assign an ID to this rating but so double click on this rating. 67 00:04:38,800 --> 00:04:42,670 And for the ID just type in here r t be four stars. 68 00:04:42,670 --> 00:04:46,010 STUDENT 4 stars. 69 00:04:46,120 --> 00:04:49,300 Student and then press Enter key on your keyboard. 70 00:04:49,410 --> 00:04:50,010 OK. 71 00:04:50,080 --> 00:04:54,570 Now let's actually drag a linearly add horizontal into this linearly I-30 call. 72 00:04:54,640 --> 00:05:00,010 And then let's actually write a large takes you into these linear left horizontal and double click on 73 00:05:00,010 --> 00:05:01,470 dislodge this view. 74 00:05:02,320 --> 00:05:04,940 And for the text just delete the text of the stakes. 75 00:05:04,990 --> 00:05:09,980 And for the idea to step in here it's the freestylers student. 76 00:05:10,160 --> 00:05:10,710 OK. 77 00:05:10,810 --> 00:05:16,630 And then let's actually drag our 18 bar into this linearly and horizontal so just select this raking 78 00:05:16,630 --> 00:05:21,110 bar here and then put it inside this linearly out horizontal OK. 79 00:05:21,130 --> 00:05:27,980 Double click on this rating bar here and are for the idea just type in here are be Freestar student. 80 00:05:28,180 --> 00:05:28,710 OK. 81 00:05:28,870 --> 00:05:34,800 And then as you can see here are let's actually select this linearly horizontal and here. 82 00:05:34,870 --> 00:05:38,770 Let's actually find the gravity attribute as it can see this is the gravity attribute. 83 00:05:38,770 --> 00:05:44,580 And here it is take place here that says Center underline horizontal and select the text view. 84 00:05:44,680 --> 00:05:49,920 And let's actually find the layout Margene and for and for the right margin just assigned the value 85 00:05:49,940 --> 00:05:50,420 20. 86 00:05:50,440 --> 00:05:52,540 So now our listeners try to select this. 87 00:05:52,540 --> 00:06:00,430 Our first rating we're here as you can see double click on it and for the rating just assigned a value 88 00:06:00,460 --> 00:06:07,120 5 select this second rating bar here for the state for the rating just assigned a value for this a fair 89 00:06:07,180 --> 00:06:11,670 rating bar here for the rating assigned to value free. 90 00:06:12,310 --> 00:06:13,230 OK. 91 00:06:13,720 --> 00:06:18,460 And this actually drag and other linearly or horizontal into this linearly Outhwaite cycle. 92 00:06:18,880 --> 00:06:25,660 And this actually select this large takes view and put it inside this linearly horizontal double click 93 00:06:25,660 --> 00:06:30,730 and this large stacks view and I deleted the text of this text you and for the ID just type in here 94 00:06:30,750 --> 00:06:33,040 takes the two stars. 95 00:06:33,040 --> 00:06:34,270 Student Okay. 96 00:06:34,450 --> 00:06:38,830 And let's actually like orating bought into this linearly or horizontally. 97 00:06:38,860 --> 00:06:46,180 So just select this right in bar here and then put it inside this linearly out horizontal OK. 98 00:06:46,240 --> 00:06:48,550 And that will Heliconius aren't rating. 99 00:06:48,940 --> 00:06:51,400 And for the top ratings just type in here too. 100 00:06:51,580 --> 00:06:55,390 And for the ID just assign r t b to stars. 101 00:06:55,390 --> 00:06:56,870 Student Okay okay. 102 00:06:57,040 --> 00:06:58,970 And then press on until key on your keyboard. 103 00:06:59,110 --> 00:07:04,360 So just let's actually select this linearly of horizontal and for the gravity. 104 00:07:04,360 --> 00:07:09,420 Check this checkbox here that says Center underline horizontal and selected this takes view. 105 00:07:09,580 --> 00:07:16,300 And for the layout Margene and here as you can see the left margin attributes assigned a value 20 for 106 00:07:16,300 --> 00:07:22,540 the right margin OK let's actually try another linearly out horizontal into this linear left vertical 107 00:07:23,470 --> 00:07:31,480 and right or large takes you into this linearly and horizontal double click on it delete the text then 108 00:07:31,550 --> 00:07:33,160 delete the text of this text view. 109 00:07:33,400 --> 00:07:40,590 And for the idea just typing here takes the one thought student okay and present it on your keyboard. 110 00:07:40,810 --> 00:07:47,930 And let's actually write R-rating but into this linearly horizontal double click on it for the regime. 111 00:07:47,950 --> 00:07:54,310 Just assign the value 1 and for the ID just type in here Arti be one star student. 112 00:07:54,550 --> 00:07:55,080 OK. 113 00:07:55,240 --> 00:07:57,420 And then press enter on your keyboard. 114 00:07:57,460 --> 00:08:03,800 So just select this linear horizontal and then actually find the gravity attribute as you can see here. 115 00:08:03,850 --> 00:08:10,030 This is the gravity attribute and then check this check box here that says Center underlined horizontal 116 00:08:11,350 --> 00:08:15,430 and then select this 61 star student text view. 117 00:08:15,550 --> 00:08:20,090 And then for the layout Margene assigned the value 24 the right margin. 118 00:08:20,230 --> 00:08:20,740 Okay. 119 00:08:20,890 --> 00:08:24,730 And let's actually drag a bottom into this linearly or two articles. 120 00:08:24,880 --> 00:08:26,810 So as you can see here this is a pattern. 121 00:08:26,890 --> 00:08:33,030 So just put it put it here and double click on it and for the text just type in here show me the results. 122 00:08:33,190 --> 00:08:37,160 And for the ID just type in here between results. 123 00:08:37,480 --> 00:08:38,250 OK. 124 00:08:38,590 --> 00:08:43,710 And let's actually find out marching for this button for the margin top. 125 00:08:43,720 --> 00:08:45,440 Assign the value 20. 126 00:08:45,920 --> 00:08:48,200 OK so now as you can see here. 127 00:08:48,550 --> 00:08:54,670 We actually designed our user interface and now let's actually go back inside this mine activity double 128 00:08:54,670 --> 00:09:02,210 file here and delete these lines of code that are actually related to the Options menu and delete this 129 00:09:02,210 --> 00:09:04,610 block of code. 130 00:09:04,610 --> 00:09:07,040 And now we can actually start coding here. 131 00:09:07,070 --> 00:09:07,550 OK. 132 00:09:07,690 --> 00:09:08,200 OK. 133 00:09:08,240 --> 00:09:15,770 Now let's actually create some takes you objects to just type in here takes view sixty five stars. 134 00:09:15,770 --> 00:09:19,330 Student Okay. 135 00:09:20,000 --> 00:09:26,000 And then put an assignment operator here that's actually cast this object to a text view object find 136 00:09:26,240 --> 00:09:30,480 view by ID or that Id taught the five stars. 137 00:09:30,500 --> 00:09:31,990 Student Okay. 138 00:09:32,690 --> 00:09:37,670 And again the statement here takes you Felix the Forsters student 139 00:09:40,370 --> 00:09:46,620 OK and then put an assignment operator here that's actually a this object to a text view object find 140 00:09:46,670 --> 00:09:51,990 view by ID or that Id dot sixty four stars. 141 00:09:51,990 --> 00:09:53,750 Student Okay. 142 00:09:53,910 --> 00:10:00,030 Essentially create another text object takes the Freestar student OK. 143 00:10:00,150 --> 00:10:07,920 Test this object or text object find view ID or that ID that the Freestar. 144 00:10:07,950 --> 00:10:09,220 Student Okay. 145 00:10:09,720 --> 00:10:15,030 And by the way if you want to you can actually copy and paste these lines of code if you want to save 146 00:10:15,030 --> 00:10:15,600 time. 147 00:10:15,750 --> 00:10:22,070 But I prefer to actually write every line of code myself so that you can see what's going on here. 148 00:10:22,080 --> 00:10:22,530 OK.
