1 00:00:00,330 --> 00:00:01,170 High or whatever. 2 00:00:01,280 --> 00:00:07,430 So now it's time to go to our main activity class and actually create some valuables in order to actually 3 00:00:07,730 --> 00:00:09,750 access these user interface components. 4 00:00:09,760 --> 00:00:14,920 But you can see that we have not changed that the taste of the Spartan So let's go to the activity under 5 00:00:14,920 --> 00:00:20,650 the light minute example here and as you can see I changed the text of this button but it's not reflecting 6 00:00:20,650 --> 00:00:20,930 here. 7 00:00:20,930 --> 00:00:22,950 So let me actually run the application again. 8 00:00:23,180 --> 00:00:26,620 So now you can see that the text of this button is get that data. 9 00:00:26,780 --> 00:00:28,550 So everything is fine so far. 10 00:00:28,580 --> 00:00:30,810 Let's go to the Android studio and let's go to them. 11 00:00:30,930 --> 00:00:36,890 Put them in the class and at the top of the file here here inside is main activity class. 12 00:00:36,890 --> 00:00:39,190 I'm going to actually create somebody else. 13 00:00:39,230 --> 00:00:44,330 The first valuable that you are going to create is going to be off the edit text so I can say edit text 14 00:00:45,260 --> 00:00:48,090 and the name of this variable is going to be EDT. 15 00:00:48,230 --> 00:00:50,850 Address right semicolon. 16 00:00:51,350 --> 00:00:55,340 The second variable it again is going to be that it takes and the name of this rally is going to be 17 00:00:55,340 --> 00:00:58,240 my EDT mph. 18 00:00:58,310 --> 00:01:09,420 So I can say EDT miles per hour semicolon the first variable is going to be again of think it takes. 19 00:01:09,420 --> 00:01:11,320 And it is going to be meters per mile. 20 00:01:11,370 --> 00:01:22,050 So I can't say it takes the name of this variable is going to be meter's jeremiad semi-colon and we 21 00:01:22,050 --> 00:01:25,960 need to actually create two more valuable for these picks views. 22 00:01:25,960 --> 00:01:37,960 So I can say Take few takes the distance semicolon and another takes a view for these takes for the 23 00:01:37,960 --> 00:01:39,090 time. 24 00:01:39,190 --> 00:01:45,640 So the next value is going to be after it again takes a few takes the time semi-colon. 25 00:01:45,790 --> 00:01:54,690 And finally we have the button button PTEN actually get the data semi-colon. 26 00:01:54,690 --> 00:02:00,270 So now that we have these valuable Let's actually initialize them inside our uncreate method. 27 00:02:00,480 --> 00:02:06,040 So let's go inside these and create Meffert and here after this set the content view method here. 28 00:02:06,330 --> 00:02:10,340 I can actually say it is the address assignment operator. 29 00:02:10,410 --> 00:02:18,480 Actually cast this object to our text editor object actually and it takes fine view by ID or that Id 30 00:02:18,500 --> 00:02:25,750 dot EDT address semicolon EDT mph assignment operator. 31 00:02:25,770 --> 00:02:35,360 It's actually Chrestus object to an edit text object find view by I-T or thoughts ID that EDT mph semicolon 32 00:02:36,090 --> 00:02:37,940 on the next rally. 33 00:02:37,980 --> 00:02:41,120 Is going to be actually this one. 34 00:02:41,150 --> 00:02:42,910 It the meters per mile. 35 00:02:42,910 --> 00:02:47,640 So let's actually change the name of this variable here to EDT meters per hour per mile. 36 00:02:47,660 --> 00:02:53,690 EDT meteor's pair might right. 37 00:02:53,690 --> 00:02:59,990 So there is actually a consistency here so I can say EDT meters per mile assignment operator less cast 38 00:02:59,990 --> 00:03:02,550 this object to an edit text object. 39 00:03:02,690 --> 00:03:12,290 And here I can't say find view about ID are that Id dot EDT meters Pyrmont right semicolon. 40 00:03:12,420 --> 00:03:15,020 Now unless actually initialize Arctic's view. 41 00:03:15,080 --> 00:03:26,840 So the distance assignment operator cast it to an object find via by ID are thought Id gutty X the this 42 00:03:26,850 --> 00:03:31,440 then its value semicolon and the next one is takes the time. 43 00:03:31,450 --> 00:03:37,660 So it takes the time assignment operator lets get this object to a text view object fine view by ID 44 00:03:37,960 --> 00:03:43,530 or that ID that takes the time to waste the time semi-colon. 45 00:03:43,630 --> 00:03:47,740 And we have this PTEN get the data so Pythian get the later. 46 00:03:47,770 --> 00:03:57,100 I mean operator lets cast this object to a button object find view Id artist Id dot PTEN get the data 47 00:03:57,350 --> 00:03:59,000 semicolon. 48 00:03:59,010 --> 00:04:05,820 Now let's actually say that this class main activity actually conforms to a view that unclick listener. 49 00:04:05,990 --> 00:04:09,250 So here I can say PTEN get the data. 50 00:04:09,290 --> 00:04:15,470 So after this line of what I'm going to say that set of listener set on unclick listener and we need 51 00:04:15,470 --> 00:04:18,100 to pass the context main activity that is right. 52 00:04:18,320 --> 00:04:23,610 So here we have an error and that's because the main Akhal-Teke class is not actually implementing the 53 00:04:23,930 --> 00:04:26,750 unclick listener interface Solus scroll to the top. 54 00:04:27,080 --> 00:04:29,110 And here it says employment's. 55 00:04:29,120 --> 00:04:35,110 So here we are already conforming or implementing these two interfaces so let's put a comma here. 56 00:04:35,150 --> 00:04:41,790 Let's also implement the view dot unclick listener interface on click listener. 57 00:04:42,140 --> 00:04:47,770 So now that you are actually implementing these unclick this in an interface we need to actually overwrite 58 00:04:48,260 --> 00:04:49,380 the unclick method. 59 00:04:49,430 --> 00:04:50,620 So let's scroll down here. 60 00:04:50,630 --> 00:04:56,800 After the incredible pace of these uncreate Smurfit inside is main activity class I can't just point 61 00:04:56,940 --> 00:05:05,230 on click on click so just press on until you're on your keyboard in order to select Smurfette and you 62 00:05:05,230 --> 00:05:10,750 can see that if it is actually overlaid it here so we can use our we can actually put our coats here 63 00:05:10,750 --> 00:05:16,900 inside the Smurfette So we are ready to add some implementations inside this unclick method in the next 64 00:05:16,900 --> 00:05:17,780 tutorial. 65 00:05:18,040 --> 00:05:21,140 Thank you very much for watching and I'll see you in the next story.
