00:00:00,360 --> 00:00:02,280

Hello this is Mortaza Cordy.



2

00:00:02,430 --> 00:00:09,750

And in this story all your way to learn how to drag or move our floating budget or our floating view



3

00:00:10,050 --> 00:00:13,510

on the screen by using the user's touch.



4

00:00:13,530 --> 00:00:19,620

So in order to do that first of all we need to access the root container or the root view.



5

00:00:19,680 --> 00:00:22,190

So by root view I am actually referring.



6

00:00:22,290 --> 00:00:27,500

Let's go into this flawed underlying view Underland lay out that XML file here.



7

00:00:28,680 --> 00:00:31,310

And now you can see this route view here.



8

00:00:31,320 --> 00:00:37,740

This relatively out which is playing the role of a root container that contains the collapsed state



9

00:00:37,770 --> 00:00:45,810

or the collapsed view and the expanded view is that the idea of this relatively out is this one root



10

00:00:45,900 --> 00:00:47,320

Underland view.



11

00:00:47,400 --> 00:00:50,170

So let's go back into this Flutey and view.



12

00:00:50,160 --> 00:00:58,170

So we start justified and here inside this class you can see that we have some instances valuables.



13

00:00:58,200 --> 00:01:00,630

Let's create another instance variable.



14

00:01:00,750 --> 00:01:08,990

It is going to be of type view and its name is going to be root view semicolon.



15

00:01:09,470 --> 00:01:15,860

So let's actually declare all of our instance variables as private so put the private keyword before



16

00:01:15,860 --> 00:01:20,160

these instance variables because it's a good programming practice to do that.



17

00:01:23,600 --> 00:01:27,780

Now we need to go inside the uncreate benefit.



18

00:01:28,040 --> 00:01:34,010

And if you're going to initialize our route to view Silis scroll down here and before adding curly brace



19

00:01:34,400 --> 00:01:35,950

of this on Christmas.



20

00:01:36,120 --> 00:01:44,070

And we to refer to this Roots view assignment operator and I can say find excuse me Vinita repetoire



21

00:01:44,070 --> 00:01:54,060

which is first floating bitted that find view by ID because here we are actually accessing a view and



22

00:01:54,060 --> 00:01:58,390

we want to assign this view to this read the view which is actually of type view.



23

00:01:58,470 --> 00:02:04,450

We don't have to cast this to any other types because we are directly accessing of you.



24

00:02:04,470 --> 00:02:12,670

So if you can say find by ID inside a Apprentice's I'm going to say are that Id dot root underline if



25

00:02:12,770 --> 00:02:22,110

you semicolon Now that be initialized this root view I can create an on Poche listener for the this



26

00:02:22,150 --> 00:02:22,390

view.



27

00:02:22,400 --> 00:02:31,730

So I went to say root view that sits on touch listener now only to pass the context because we do not



28

00:02:31,730 --> 00:02:36,920

want to actually create an anonymous inner class since insight is unclear if it is going to be too much



29

00:02:36,920 --> 00:02:43,940

crowded and it's not a good programming practice eboy that everything should be encapsulated any and



30

00:02:44,030 --> 00:02:50,210

everything should be done in its own methods or functions so set on patches and or inside Apprentice's.



31

00:02:50,210 --> 00:02:55,020

I am going to say the context that we need to pass the context the context is disserve is floating view



32

00:02:55,020 --> 00:02:58,300

so Service that this.



33

00:02:58,420 --> 00:02:59,410

Now we have an error.



34

00:02:59,410 --> 00:03:04,110

It says that we have to now that we passed this context to the set and to each listener.



35

00:03:04,510 --> 00:03:10,650

And we are saying that this floating View service is going to be the listener for the touch of the user.



36

00:03:10,810 --> 00:03:20,200

This fluty view service that java file this class now must implement the unattach listener interface



37

00:03:20,290 --> 00:03:23,650

and override the untouched method.



38

00:03:23,680 --> 00:03:26,070

So let's scroll to the top here.



39

00:03:26,470 --> 00:03:33,380

It says publish class fluting View service extends service class implements view that unclick listener



40

00:03:33,400 --> 00:03:34,190

interface.



41

00:03:34,240 --> 00:03:40,120

So we now need to implement another interface so people are coming here and now we're going to see view



42

00:03:40,480 --> 00:03:42,580

that on capital or.



43

00:03:42,660 --> 00:03:47,140

Okay touch on that listener.



44

00:03:47,340 --> 00:03:48,120

That's it.



45

00:03:48,160 --> 00:03:53,210

Now we need to override the on touch method inside our class.



46

00:03:53,350 --> 00:03:54,620

So let's scroll down here.



47

00:03:54,640 --> 00:03:56,990

And after this and click on it.



48

00:03:57,130 --> 00:04:01,810

So make sure that you are actually still inside this class.



49

00:04:02,260 --> 00:04:10,660

And after the end in curly brace of our unclick listener uncle Mefford here and before the anti-cruelty



50

00:04:10,790 --> 00:04:17,980

place of the class the fluting you said with class if you're going to see on Poche now the autocomplete



51

00:04:18,000 --> 00:04:20,820

feature helped me to override this method.



52

00:04:20,910 --> 00:04:22,330

So here it is on my phone.



53

00:04:22,470 --> 00:04:23,560

So it is written false.



54

00:04:23,560 --> 00:04:25,420

Let's delete this return false.



55

00:04:25,430 --> 00:04:27,840

Here let's go inside this method.



56

00:04:27,840 --> 00:04:32,160

Notice that the Smurfette needs to return a value of a boolean.



57

00:04:32,310 --> 00:04:36,440

So I think that's enough for this story or indirect tutorial.



58

00:04:36,540 --> 00:04:39,240

We're going to implement this on touch Meffert.



59

00:04:39,630 --> 00:04:41,790

So thank you very much for watching.



60

00:04:42,120 --> 00:04:44,960

And I look forward to seeing you in the next story.
