1 00:00:00,150 --> 00:00:05,850 Hire everyone in this theater all we're gonna go ahead and create another Android application. 2 00:00:05,850 --> 00:00:06,750 So just click on this. 3 00:00:06,750 --> 00:00:12,930 Start in your Android studio project here and then for the name of your application just step in here 4 00:00:12,960 --> 00:00:21,960 app 54 and then click on next and here choose AP A16 Android 4.1 Jelly Bean for a minimum SDK and then 5 00:00:21,960 --> 00:00:29,260 click on next and here choose empty activity here and then click on next and here click on finish. 6 00:00:29,460 --> 00:00:33,140 So now as you can see here our project is actually created. 7 00:00:33,210 --> 00:00:35,890 So it's actually double and it's a race folder here. 8 00:00:36,030 --> 00:00:41,270 And then double double click on the layout for there and then return this activity underline minute 9 00:00:41,280 --> 00:00:41,980 example. 10 00:00:42,090 --> 00:00:46,380 So here first of all we want to actually design the user interface of our application. 11 00:00:46,530 --> 00:00:51,920 So just select is hellova over the text view here and then press on delete key on your keyboard. 12 00:00:52,110 --> 00:00:57,950 So first of all we need to actually write a linearly or two vertical into this relatively out here. 13 00:00:58,050 --> 00:01:03,550 So just put this linearly out vertical at the center of this relatively here. 14 00:01:03,900 --> 00:01:07,270 And then let's actually drag our textfield. 15 00:01:07,500 --> 00:01:13,170 Let's actually select is a plain text here inside this text fields a folder just select it and put it 16 00:01:13,230 --> 00:01:16,250 at the center of this linearly at vertical. 17 00:01:16,260 --> 00:01:16,900 OK. 18 00:01:17,190 --> 00:01:19,740 So WDTN this eddy takes here. 19 00:01:19,740 --> 00:01:23,620 And for the ID just type in here it is the content. 20 00:01:23,700 --> 00:01:29,640 It is the content title and and press on entelechy on your keyboard. 21 00:01:29,880 --> 00:01:35,820 And then let's actually find the hint attribute that is actually related to this text field inside this 22 00:01:35,820 --> 00:01:39,030 property section here as you can see this is the hint attribute. 23 00:01:39,030 --> 00:01:39,550 OK. 24 00:01:39,600 --> 00:01:49,180 So for the hand just type in here please enter the title of notification. 25 00:01:49,470 --> 00:01:49,790 OK. 26 00:01:49,800 --> 00:01:52,470 And that person entelechy on your keyboard. 27 00:01:52,470 --> 00:01:55,310 So as you can see here this is the heat of this stakes field. 28 00:01:55,560 --> 00:01:59,880 So let's actually and other textfield into this linearly at vertical. 29 00:01:59,880 --> 00:02:01,810 So inside this it takes field folder. 30 00:02:01,920 --> 00:02:08,490 Just select the plain text here and put it at the center of this linearly alphabetical double click 31 00:02:08,490 --> 00:02:09,150 on it. 32 00:02:09,150 --> 00:02:17,970 And for the ID just type in here EDT a content editing content text and in person Enter key on your 33 00:02:17,970 --> 00:02:23,270 keyboard and let's actually assign a value to the hint of this edit takes. 34 00:02:23,280 --> 00:02:34,980 So for the hand to step in here please enter the text of please enter the text of notification 35 00:02:38,410 --> 00:02:40,680 and then person entelechy on your keyboard. 36 00:02:40,990 --> 00:02:42,850 So let's actually select this one here. 37 00:02:42,920 --> 00:02:50,290 This first textfield and for the Heyns just put this capital-T let me actually change this t to capital-T 38 00:02:50,470 --> 00:02:53,550 title and then press on interview on your keyboard. 39 00:02:53,560 --> 00:02:58,130 So now it's actually the right button here into this linearly aesthetical. 40 00:02:58,150 --> 00:03:01,990 So as you can see here I have this button inside widgets folder. 41 00:03:01,990 --> 00:03:07,970 Just select it and put it at the center of this linearly vertical and double click on it. 42 00:03:08,010 --> 00:03:10,590 And for the text it's just typing here. 43 00:03:10,660 --> 00:03:13,650 Notify notify me. 44 00:03:14,200 --> 00:03:21,570 And for the ideas they've been here between notify and then present Enter key on your keyboard. 45 00:03:21,580 --> 00:03:26,680 So let's actually go inside this main activity file here and now this actually declares some objects 46 00:03:26,740 --> 00:03:28,900 inside this main activity class. 47 00:03:28,900 --> 00:03:35,590 So first of all I need to actually declare an edit text object so EDT a content 48 00:03:38,080 --> 00:03:49,600 title and then put a semi-colon at the end of your statement and again Eddie takes EDT content text. 49 00:03:49,940 --> 00:03:52,910 And again I need to put a semi-colon at the end of my statement. 50 00:03:52,910 --> 00:03:56,610 And here again I want to actually declare about a button. 51 00:03:56,720 --> 00:03:59,060 So PTEN notify. 52 00:03:59,900 --> 00:04:02,750 And then I need to put a semicolon at the end of my statement. 53 00:04:02,750 --> 00:04:09,320 So again inside the uncreate Meffert we need to actually instantiate these objects that we declared 54 00:04:09,380 --> 00:04:11,150 inside this in a computer class. 55 00:04:11,180 --> 00:04:16,850 So first what you want to instantiate is then create this EDT content's titel assignment operator. 56 00:04:16,850 --> 00:04:25,830 So here I need to cestus object to a it takes object find you by ID or that ID that EDT content title 57 00:04:26,050 --> 00:04:32,690 and that I need to put a semicolon at the end of my statement and ADT cont'd text assignment operator. 58 00:04:32,840 --> 00:04:42,760 And then here I need to cast this object to a detailed object find view by ID or ID that it is EDT content. 59 00:04:44,370 --> 00:04:50,290 TEXT So a French dad of it didn't assign an ID to this second. 60 00:04:50,770 --> 00:04:56,620 So I made a mistake inside this activity Underland minute exam and I assigned is city. 61 00:04:56,690 --> 00:04:58,770 So I need to change the C to D. 62 00:04:58,950 --> 00:04:59,200 OK. 63 00:04:59,210 --> 00:05:01,490 And then I need to press on into the key on my keyboard. 64 00:05:01,770 --> 00:05:04,060 So let's go back to our main activity that java file. 65 00:05:04,080 --> 00:05:07,950 So is it the content or text. 66 00:05:08,270 --> 00:05:08,900 Okay. 67 00:05:08,970 --> 00:05:11,630 And then I need to put a semicolon at the end of my statement. 68 00:05:11,880 --> 00:05:18,740 And here I need to again instantiate this PTEN notify object so notify assignment operator and that 69 00:05:18,740 --> 00:05:26,540 he or I need to chastise object to a button object find view ID or that Id towards Pythian notify and 70 00:05:26,540 --> 00:05:29,080 that I need to put a semicolon at the end of my statement. 71 00:05:29,370 --> 00:05:34,880 And here I need to actually make the Spartan BT and notify our listener to the clicks of the user. 72 00:05:34,980 --> 00:05:41,850 So here I can't just type in between not notify that sets unclick listener and that I need to pass the 73 00:05:41,850 --> 00:05:47,760 context so the context is going to be my inactivity that this and here at the top I need to actually 74 00:05:47,760 --> 00:05:55,770 implement this view that Uncle listener interface so views that unclick listener. 75 00:05:56,040 --> 00:06:00,650 And then we need to actually override the ankle Comerford inside our main activity class. 76 00:06:00,720 --> 00:06:06,740 So he had I had just been unclick and he and as you can see we are all in this uncle Mefford inside. 77 00:06:06,750 --> 00:06:11,760 Our main activity class and as you can see here the errors are gone and our application is actually 78 00:06:12,060 --> 00:06:14,570 compiling our codes are compiling now. 79 00:06:14,760 --> 00:06:21,210 So now inside our main activity class I'm going to actually paste in a method here and then I'm going 80 00:06:21,210 --> 00:06:24,240 to explain to you what's going on here. 81 00:06:24,840 --> 00:06:29,450 So as you can see here these are the lines of code that actually pasted here. 82 00:06:29,460 --> 00:06:32,050 So as you can see I have my foot here. 83 00:06:32,280 --> 00:06:38,730 And the access modifier of this method is private's and the return type of this method is void. 84 00:06:38,850 --> 00:06:41,360 And this means that this if it returns nothing. 85 00:06:41,430 --> 00:06:42,010 OK. 86 00:06:42,240 --> 00:06:45,460 And the name of this method is shown notification. 87 00:06:45,480 --> 00:06:47,930 So you want to show a notification to the user. 88 00:06:48,000 --> 00:06:48,610 OK. 89 00:06:48,900 --> 00:06:55,650 So in line 44 in order to actually create on notification and in order to show notification to the user 90 00:06:56,010 --> 00:07:01,760 first that what we need to actually create a notification compact that build that object. 91 00:07:01,770 --> 00:07:08,630 So here as you can see I created this object Builder which is of type notification combat compact that 92 00:07:08,700 --> 00:07:09,090 builder. 93 00:07:09,090 --> 00:07:09,730 OK. 94 00:07:10,080 --> 00:07:13,190 And here as you can see I am instantiating this object. 95 00:07:13,230 --> 00:07:15,560 New notification compact that builder. 96 00:07:15,750 --> 00:07:23,330 And here as an argument we need to pass the context so the context is main activity that is an inline 97 00:07:23,370 --> 00:07:25,320 45 as you can see here. 98 00:07:25,410 --> 00:07:30,720 I am actually specifying the icon of the notification that I am to show to the user. 99 00:07:30,900 --> 00:07:37,420 So I refer to this builder here builder that set small icon as you can see here. 100 00:07:37,440 --> 00:07:40,920 I want to set a small icon for this notification. 101 00:07:41,080 --> 00:07:42,680 Arthur triable that image. 102 00:07:42,840 --> 00:07:49,380 So on my desktop I have an image for this notification that I actually downloaded from the Internet. 103 00:07:49,410 --> 00:07:50,510 So this is the image. 104 00:07:50,700 --> 00:07:51,230 OK. 105 00:07:51,390 --> 00:07:57,930 I just need to actually copy this image so I just need to right click on this image here and then click 106 00:07:57,930 --> 00:08:05,940 on copy copy image that PMG and let's actually go to an android studio and here inside our project structure 107 00:08:06,270 --> 00:08:12,240 inside this press folder just select this triable for rebel directory here as you can see right click 108 00:08:12,240 --> 00:08:15,230 on it and then click on paste. 109 00:08:15,240 --> 00:08:17,460 So now click on OK here. 110 00:08:17,550 --> 00:08:21,190 So as you can see here now I have this image inside my drivable folder. 111 00:08:21,390 --> 00:08:25,610 So let's go back to our main activity class and as you can see I am actually setting this image are 112 00:08:25,640 --> 00:08:32,390 that triable that image for this small icon of thus far this small icon of this notification. 113 00:08:32,420 --> 00:08:34,230 OK Bill that's a smile icon. 114 00:08:34,230 --> 00:08:41,220 So as you can see here I am actually specifying the text of the of the notification that I want to show 115 00:08:41,220 --> 00:08:41,880 to the user. 116 00:08:41,970 --> 00:08:44,990 So Bill there that sit content text. 117 00:08:45,120 --> 00:08:45,650 OK. 118 00:08:45,870 --> 00:08:52,260 So the content taste is going to be the value of these are textfield of this I to go back to our activity 119 00:08:52,260 --> 00:08:53,550 mainit example. 120 00:08:53,550 --> 00:08:55,910 So here I just need to click on this clear cache. 121 00:08:56,520 --> 00:09:02,620 So as you can see here for the notification content takes as you can see I just need to get this value 122 00:09:02,620 --> 00:09:05,240 with the value of this text field here. 123 00:09:05,260 --> 00:09:10,360 As you can see so sort of naturally DoubleClick and distasteful as you can see the idea is content takes. 124 00:09:10,380 --> 00:09:11,070 Right. 125 00:09:11,130 --> 00:09:16,780 So you want to get this value and put that as the value of the text of this notification. 126 00:09:16,800 --> 00:09:17,250 OK. 127 00:09:17,300 --> 00:09:18,710 So that content text. 128 00:09:18,760 --> 00:09:22,280 So editing content text that text that was thrown. 129 00:09:22,560 --> 00:09:26,980 As you can see here I want to actually get this value and convert it to a string value. 130 00:09:27,180 --> 00:09:32,790 And then I can actually pass that value as the argument as the argument of this content text here. 131 00:09:32,820 --> 00:09:39,600 As you can see and hear in line 47 I am specifying the title of the content sort of the title of the 132 00:09:39,600 --> 00:09:41,670 notification that you want to show to the user. 133 00:09:41,760 --> 00:09:48,250 So there that content to title edit content text that get text that 2st. 134 00:09:48,360 --> 00:09:55,340 So here as you can see I need to change the EDT content text to EDT content title. 135 00:09:55,440 --> 00:09:59,940 So you want to actually get the content to hightail it Itay content title. 136 00:10:00,000 --> 00:10:03,270 So insight or activity under alignment affects them in here. 137 00:10:03,660 --> 00:10:06,200 As you can see I have the added text here right. 138 00:10:06,210 --> 00:10:08,440 Please enter the title of the notification. 139 00:10:08,490 --> 00:10:13,560 So if Y.W.C.A. edit takes here as you can see the title is it its contents title. 140 00:10:13,560 --> 00:10:19,200 So you want to get the text of this editor of this text field and when all you want to actually use 141 00:10:19,200 --> 00:10:22,620 that as the title of the notification that you want to show to the user. 142 00:10:22,860 --> 00:10:28,760 So as you can see here this is going to be the title EDT contents title that get text that was strange 143 00:10:29,100 --> 00:10:34,430 and then I can actually pass that value as the argument of the Smurfette so content title of this bill 144 00:10:34,430 --> 00:10:35,070 that object. 145 00:10:35,070 --> 00:10:35,900 OK. 146 00:10:36,570 --> 00:10:39,420 So here as you can see I have a comment. 147 00:10:39,420 --> 00:10:40,680 I created a comment here. 148 00:10:40,800 --> 00:10:46,370 So use it on click on notification so when the user clicks on the notification what it is going to happen.
