00:00:00,210 --> 00:00:02,500

Hello this is Martez or karate.



2

00:00:02,610 --> 00:00:09,450

And in this material we are going to completely implement our constructor here inside is my custom view



3

00:00:09,450 --> 00:00:10,330

class.



4

00:00:10,410 --> 00:00:16,220

First of all we need to create some instance valuables inside our class so let's do that now.



5

00:00:16,230 --> 00:00:23,560

So remember what I told you about instance variables always declare your instance variables as private.



6

00:00:23,730 --> 00:00:25,520

So let's do that private.



7

00:00:25,800 --> 00:00:32,400

And now we need to specify the type the type is going to be of the integer The name is going to be View



8

00:00:32,580 --> 00:00:38,300

color semicolon private in teacher.



9

00:00:38,380 --> 00:00:43,050

And here we need to specify the text color which is a can of type Integer.



10

00:00:43,210 --> 00:00:50,180

And finally private's 3 and it is green and its name is going to be view text semicolon.



11

00:00:50,530 --> 00:00:55,360

So you can see that I declared this instance variables here right but let's switch to the my custom



12

00:00:55,360 --> 00:00:57,430

view attributes that XML file here.



13

00:00:57,460 --> 00:01:05,470

We created these attributes and according to these attributes I created instance variables inside my



14

00:01:05,470 --> 00:01:07,090

custom view that Lafite.



15

00:01:07,120 --> 00:01:15,130

So remember that whenever you create an attribute inside your XML file for your custom view make sure



16

00:01:15,130 --> 00:01:20,500

to create an instance variable that is related to that attribute inside your class.



17

00:01:20,500 --> 00:01:22,780

So here we created this instance variables.



18

00:01:22,780 --> 00:01:25,030

Now we need to go inside our constructor.



19

00:01:25,030 --> 00:01:30,670

So after calling the super constructor we are going to initialize this instance variables.



20

00:01:30,670 --> 00:01:37,570

So how we are going to initialize these instance variables by accessing the attributes that we put inside



21

00:01:37,590 --> 00:01:42,890

are my custom view attributes that identify by accessing these values.



22

00:01:42,950 --> 00:01:45,930

We are going to initialize our instance variables.



23

00:01:45,970 --> 00:01:52,900

So that's why I told you whenever you put an attribute inside your custom view that exemplified make



24

00:01:52,900 --> 00:01:59,530

sure to create an instance variable inside your giallo fine for that specific attribute.



25

00:01:59,530 --> 00:02:03,370

So we need to get inside my custom view that have a file inside the constructor.



26

00:02:03,370 --> 00:02:12,070

After calling this Super constructor we're going to create something called typed Aure typed at 8 so



27

00:02:12,070 --> 00:02:13,820

the name is going to be typed at 8.



28

00:02:13,840 --> 00:02:14,820

Assignment operator.



29

00:02:14,830 --> 00:02:24,390

Now we're going to say context that gets Feme that pain styled attributes.



30

00:02:24,410 --> 00:02:29,870

So now first as you can see if you need to pass the attribute said call this function again you know



31

00:02:29,870 --> 00:02:35,830

that just to show you these attributes these arguments that going to pass to this function.



32

00:02:35,960 --> 00:02:39,320

First if you are going to pass the attributes set and then.



33

00:02:39,360 --> 00:02:43,210

So let's actually pass the attributes here attribute set comma.



34

00:02:43,250 --> 00:02:50,180

Now we need to pass the resource phi or the exemplify that we created for a custom view in order to



35

00:02:50,180 --> 00:02:52,340

specify the attributes.



36

00:02:52,340 --> 00:02:57,170

So we are going to say our DOT style of Eldard.



37

00:02:57,260 --> 00:02:58,940

So here it is really important.



38

00:02:58,940 --> 00:03:05,540

Let's go inside are my custom attributes that is in a file here as you can see we created attach called



39

00:03:05,840 --> 00:03:07,260

declare style.



40

00:03:07,310 --> 00:03:10,030

Its name is my custom view.



41

00:03:10,130 --> 00:03:10,800

Right.



42

00:03:10,940 --> 00:03:13,230

So now we're going to refer to this name.



43

00:03:13,340 --> 00:03:15,800

Let's go inside are my custom be that have a file.



44

00:03:15,800 --> 00:03:25,140

So it is our database that my custom view karma to specify a default value for this type attributes



45

00:03:25,140 --> 00:03:30,220

the let's pass zero comma and again zero as the final argument.



46

00:03:30,260 --> 00:03:31,620

So let me show you these arguments.



47

00:03:31,620 --> 00:03:37,000

Here we have this default style attribute zero undefined style resource.



48

00:03:37,190 --> 00:03:39,870

So let's put a semicolon at the end of our statement.



49

00:03:39,950 --> 00:03:43,440

Let me create a new line so that you can see what's going on here.



50

00:03:44,320 --> 00:03:51,310

So first we passed the attributes set that we get from this a constructor and then we are passing this.



51

00:03:51,310 --> 00:04:00,760

Name the name of our custom view our style that my custom view and the value zero as the default style



52

00:04:00,790 --> 00:04:01,470

attribute.



53

00:04:01,480 --> 00:04:04,990

And about you again 0 4 the default style resource.



54

00:04:05,170 --> 00:04:13,540

Now here after that you actually created this typed Arri we are going to create a try catch statement



55

00:04:13,540 --> 00:04:18,070

here try and catch some exception.



56

00:04:18,460 --> 00:04:21,130

So let's open and close this block by using these collaborations.



57

00:04:21,130 --> 00:04:22,240

Let's go into these tribal.



58

00:04:22,240 --> 00:04:25,860

So you are actually putting all coats here inside this right block.



59

00:04:25,870 --> 00:04:31,340

Maybe actually something goes wrong so that we can actually catch the exception here because you're



60

00:04:31,360 --> 00:04:33,540

dealing with a typed error.



61

00:04:33,550 --> 00:04:36,390

Now we can initialize our instance variables.



62

00:04:36,430 --> 00:04:39,050

So the first instance variable is view color.



63

00:04:39,070 --> 00:04:42,390

So now we can say View color assignment operator.



64

00:04:42,400 --> 00:04:44,740

Now we have this tied at a right.



65

00:04:44,800 --> 00:04:48,550

So let's say types are a data type of our view color is integer.



66

00:04:48,670 --> 00:04:52,160

So now we can see that gets in teacher.



67

00:04:52,210 --> 00:04:57,300

Our dot Styler bill that.



68

00:04:57,530 --> 00:05:04,550

So now we can access the color attributes the view color attributes that we created inside our my custom



69

00:05:04,550 --> 00:05:05,970

view attributes that exemplify.



70

00:05:05,990 --> 00:05:15,500

So we can say my custom view because the name of that style label attribute is my custom view and then



71

00:05:15,560 --> 00:05:17,460

we have this text color.



72

00:05:17,570 --> 00:05:20,600

We have this view color and this we have viewed text.



73

00:05:20,600 --> 00:05:21,810

So we have this view color.



74

00:05:21,860 --> 00:05:23,100

Let's use this one.



75

00:05:23,450 --> 00:05:30,020

And we need to put a comma here and provide a default value for our attribute here semicolon.



76

00:05:30,620 --> 00:05:32,170

Let me create a new line here.



77

00:05:32,180 --> 00:05:36,060

Now the second instance variable that you want to initialize.



78

00:05:36,200 --> 00:05:38,210

Is this a text color.



79

00:05:38,210 --> 00:05:45,770

So let's say text color assignment operator again typed every that gets in teacher.



80

00:05:45,810 --> 00:05:54,660

And here are dot style level dot my custom view and lets access this one text color comma and then this



81

00:05:54,800 --> 00:05:57,470

has the value 0 as the default value semicolon.



82

00:05:57,500 --> 00:06:03,330

Now let's initialize the view actually not the text.



83

00:06:03,500 --> 00:06:10,050

So we have this mutex assignment operator times Ari that jet stream.



84

00:06:10,060 --> 00:06:11,390

This time it is of type string.



85

00:06:11,390 --> 00:06:13,170

So we get this strange.



86

00:06:13,640 --> 00:06:21,540

And we see our That style liberal that my custom view view text semicolon.



87

00:06:21,590 --> 00:06:29,950

Now inside this catch block we can say pipes aere that recycle.



88

00:06:30,010 --> 00:06:33,310

So let me hold a comment on my keyboard.



89

00:06:33,390 --> 00:06:36,910

You can actually do that and then click on is recycle here.



90

00:06:37,860 --> 00:06:42,840

In order to see the documentation of this method if you are using a Windows machine you can hold down



91

00:06:42,840 --> 00:06:46,920

the control key on your keyboard and then click on that second method.



92

00:06:46,940 --> 00:06:48,810

Here take a look at this documentation.



93

00:06:48,810 --> 00:06:56,010

Here take a look at this comment it says a recycles the typed Aure to be reused by a ladle color.



94

00:06:56,010 --> 00:07:03,520

So if anything goes wrong in initialising odd instance variable this recycle is going to actually the



95

00:07:03,550 --> 00:07:06,690

pipes are ready to be reused by a later color.



96

00:07:06,690 --> 00:07:08,510

Let me close this file here.



97

00:07:08,550 --> 00:07:11,660

Now that the initial eyes are instance variables.



98

00:07:11,660 --> 00:07:15,300

Again I think that's enough for this tutorial in the next tutorial.



99

00:07:15,570 --> 00:07:18,520

We're going to implement the underarm effect.



100

00:07:18,570 --> 00:07:20,910

Inside are my custom view class.



101

00:07:20,910 --> 00:07:22,500

Thank you very much for watching.



102

00:07:22,830 --> 00:07:24,590

I'll see you in the next tutorial.
