1

00:00:00,210 --> 00:00:06,840

So as you can see here I am saying that if the value of this false and true valuable is not true.



2

00:00:06,930 --> 00:00:08,010

So it is false.



3

00:00:08,040 --> 00:00:10,830

Ok then execute this line of quote here.



4

00:00:10,880 --> 00:00:14,490

See Ex-Files and to know that said checked.



5

00:00:14,490 --> 00:00:14,950

True.



6

00:00:15,000 --> 00:00:19,490

So as you can see here this object is actually related to this component here.



7

00:00:19,490 --> 00:00:20,640

This checkbox.



8

00:00:20,670 --> 00:00:23,700

So as you can see here this text box is actually on.



9

00:00:24,000 --> 00:00:27,000

So this line of code here is actually executed.



10

00:00:27,000 --> 00:00:31,500

So the value of this is false and true value label is actually false.



11

00:00:31,500 --> 00:00:36,460

The value of this expression is false false and true results in a false value.



12

00:00:36,480 --> 00:00:37,310

OK.



13

00:00:37,650 --> 00:00:41,980

So let's actually comment out of this if else statement here



14

00:00:45,900 --> 00:00:50,880

and then let's actually typing these statements in another way.



15

00:00:50,940 --> 00:00:54,550

So each c x false and true.



16

00:00:54,720 --> 00:01:03,660

Yes that said checked and then it's actually putting a paragraph brackets false and true questionmark



17

00:01:04,080 --> 00:01:06,980

true otherwise false.



18

00:01:07,670 --> 00:01:08,560

OK.



19

00:01:09,250 --> 00:01:13,260

See X false and true.



20

00:01:13,380 --> 00:01:18,210

No Dot said check it.



21

00:01:18,210 --> 00:01:25,680

Let's actually put in our program brackets here not false and true and this means if the value of this



22

00:01:25,790 --> 00:01:32,910

for false central value is false then assigned a value of true to this said check the method that is



23

00:01:32,910 --> 00:01:34,570

related to this object.



24

00:01:34,590 --> 00:01:37,000

See it's x false and true no.



25

00:01:37,170 --> 00:01:40,950

Otherwise assign the value false to this object.



26

00:01:40,950 --> 00:01:48,210

So as you can see here in the emulator the value of these false and true value is actually false.



27

00:01:48,210 --> 00:01:54,120

So as you can see we specify that if the value of this false central value but is false then assign



28

00:01:54,120 --> 00:01:55,890

the value true to this checkbox.



29

00:01:55,890 --> 00:01:58,420

So as you can see this tick box is actually on.



30

00:01:58,550 --> 00:02:02,280

So let's actually run our project again and see what happens.



31

00:02:02,280 --> 00:02:08,180

So as you can see here it's now showing the same results again the value of this false and true variable



32

00:02:08,250 --> 00:02:09,430

is actually false.



33

00:02:09,450 --> 00:02:11,510

So this checkbox is actually checked.



34

00:02:11,640 --> 00:02:12,440

OK.



35

00:02:12,510 --> 00:02:14,550

So hopefully that makes sense.



36

00:02:14,550 --> 00:02:20,580

So let let me explain again here we actually specify that if the value of this false and true value



37

00:02:20,600 --> 00:02:27,480

bet is true then assign the value true to this said Chicot method that is related to this see x false



38

00:02:27,510 --> 00:02:29,280

and true yes object.



39

00:02:29,280 --> 00:02:38,000

So this object is actually related to this component and otherwise if the value of this false central



40

00:02:38,000 --> 00:02:43,210

value but is actually false then assign the value false to this object.



41

00:02:43,250 --> 00:02:43,900

OK.



42

00:02:44,120 --> 00:02:47,580

So as you can see here this checkbox is actually is actually checked up.



43

00:02:47,890 --> 00:02:50,120

OK so this sequence is not on.



44

00:02:50,420 --> 00:02:56,630

And here we actually specify that if the value of this false and true value is actually false then assign



45

00:02:56,630 --> 00:02:58,460

the value true to this object.



46

00:02:58,520 --> 00:03:01,190

As you can see otherwise assign the value false.



47

00:03:01,310 --> 00:03:03,850

So this value is actually false.



48

00:03:03,890 --> 00:03:07,520

So it is actually assigning the value true to this check box here.



49

00:03:07,550 --> 00:03:09,750

As you can see the search box is actually on.



50

00:03:10,100 --> 00:03:11,840

So hopefully that makes sense.



51

00:03:11,870 --> 00:03:12,860

Ok everyone.



52

00:03:12,860 --> 00:03:18,950

Now let's actually go back inside this content underline that example and then let's actually put in



53

00:03:19,280 --> 00:03:26,470

a linear layout horizontal into these linearly Ellsworthy call and then let's actually put in a larger



54

00:03:26,480 --> 00:03:29,340

takes you into these linear layouts.



55

00:03:29,670 --> 00:03:30,010

OK.



56

00:03:30,020 --> 00:03:34,210

As you can see the color of this linearly out as you can see is orange.



57

00:03:34,220 --> 00:03:40,670

OK when I actually hover over these linearly out when I want to put this large takes you into These



58

00:03:40,940 --> 00:03:41,770

are linearly.



59

00:03:41,790 --> 00:03:42,460

OK.



60

00:03:42,860 --> 00:03:48,680

So as you can see now this text is actually inside these linear horizontal.



61

00:03:48,830 --> 00:03:51,960

So let's actually double click on this large takes.



62

00:03:52,520 --> 00:03:59,070

And then for the text just type in here false and false.



63

00:04:00,100 --> 00:04:00,640

OK.



64

00:04:00,680 --> 00:04:02,460

Press Enter key on your keyboard.



65

00:04:02,720 --> 00:04:10,370

So as you can see now our text view is ready and then actually try again on two checkboxes into this



66

00:04:10,370 --> 00:04:11,930

linear layout.



67

00:04:11,960 --> 00:04:14,230

So let's actually double click on this checkbox.



68

00:04:14,300 --> 00:04:15,930

So for the text or in here.



69

00:04:16,040 --> 00:04:16,700

Yes.



70

00:04:16,940 --> 00:04:23,740

And for the idea just type in here see x false and false.



71

00:04:24,230 --> 00:04:24,870

Yes.



72

00:04:26,590 --> 00:04:32,310

OK let's actually do like in another checkbox into this linearly out.



73

00:04:32,590 --> 00:04:40,090

So checkbox put it here beside this checkbox here and then double click on this checkbox.



74

00:04:40,270 --> 00:04:43,100

And for the text just type in here no.



75

00:04:43,210 --> 00:04:51,650

And for the ID just type in here see x false and fonts.



76

00:04:52,330 --> 00:04:53,350

No.



77

00:04:53,970 --> 00:04:54,780

OK.



78

00:04:55,240 --> 00:05:01,810

And then click on this linearly or horizontal and then as you can see actually find the gravity attributes



79

00:05:02,350 --> 00:05:06,410

and then check these our center underline horizontal checkbox here.



80

00:05:06,430 --> 00:05:07,020

OK.



81

00:05:07,030 --> 00:05:10,830

And let's actually go back and say this main activity the java file here.



82

00:05:11,050 --> 00:05:14,960

So now let's actually create a comment here.



83

00:05:15,310 --> 00:05:20,470

So false and false.



84

00:05:21,690 --> 00:05:28,840

Ok so here are the top of the screen as you can see when you are actually creating objects from those



85

00:05:29,100 --> 00:05:31,110

Blondie's checkbox classes here.



86

00:05:31,120 --> 00:05:36,970

I actually created a comment and now I want to actually create two other checkbox objects.



87

00:05:36,970 --> 00:05:42,430

So checkbox see X fonts and fonts.



88

00:05:42,940 --> 00:05:43,940

Yes.



89

00:05:44,710 --> 00:05:48,190

And then I actually put in an assignment operator here.



90

00:05:48,430 --> 00:06:00,280

So here I need to cast this object to a checkbox object find view by id r that Id dot c h x false and



91

00:06:00,760 --> 00:06:01,590

false.



92

00:06:01,870 --> 00:06:02,720

Yes.



93

00:06:03,190 --> 00:06:04,210

OK.



94

00:06:04,240 --> 00:06:15,140

Again let's actually create another checkbox see as X Files and follows no assignment operator here.



95

00:06:15,160 --> 00:06:26,850

I need to cast this object to a checkbox object find you by I-T or that Id dot C-h X Faunce and false.



96

00:06:26,980 --> 00:06:27,810

No.



97

00:06:28,310 --> 00:06:33,780

OK so now let's actually interact with these checkboxes here.



98

00:06:34,240 --> 00:06:36,460

So let's actually scroll down the screen here.



99

00:06:36,460 --> 00:06:40,370

Now let's actually create a comment OK.



100

00:06:40,420 --> 00:06:45,010

False and false.



101

00:06:45,040 --> 00:06:51,300

So let's actually create a boolean variable named false and false.



102

00:06:52,390 --> 00:06:57,930

And then I put an assignment operator here and then I want to actually assign a value to this variable



103

00:06:57,940 --> 00:07:02,190

fonts and fonts.



104

00:07:03,070 --> 00:07:03,300

OK.



105

00:07:03,310 --> 00:07:09,520

As you can see I created a boolean expression here and then I want to assign the result of this expression



106

00:07:09,520 --> 00:07:12,770

to this value a false and false.



107

00:07:12,790 --> 00:07:19,090

So if the result of this expression is actually true that true value is going to be assigned to this



108

00:07:19,210 --> 00:07:25,990

variable and if that is the result of this expression is actually false that font's value is going to



109

00:07:25,990 --> 00:07:28,260

be assigned to this variable OK.



110

00:07:28,660 --> 00:07:31,550

So let's actually create an if statement here.



111

00:07:31,660 --> 00:07:36,630

If false and false actually has the value.



112

00:07:36,630 --> 00:07:37,000

True.



113

00:07:37,070 --> 00:07:42,120

So now it can actually execute this line of code inside of these if statement.



114

00:07:42,130 --> 00:07:47,670

So C-h x files and files yes.



115

00:07:47,730 --> 00:07:50,170

That said check it.



116

00:07:50,320 --> 00:07:51,860

True.



117

00:07:52,500 --> 00:07:53,400

OK.



118

00:07:53,620 --> 00:07:58,740

Else if not false and false.



119

00:07:59,320 --> 00:08:04,320

And this means if the value of this false and false variable is not true.



120

00:08:04,420 --> 00:08:05,780

So it is false.



121

00:08:05,950 --> 00:08:09,530

Then execute this line of code inside of this curly braces.



122

00:08:09,570 --> 00:08:10,460

C x.



123

00:08:10,470 --> 00:08:13,790

False and false.



124

00:08:13,810 --> 00:08:17,350

No that said check it.



125

00:08:17,710 --> 00:08:19,820

True OK.



126

00:08:19,930 --> 00:08:22,670

So now let me explain again what's going on here.



127

00:08:23,050 --> 00:08:29,390

So first of all I actually created a boolean variable and then I assigned a value to this ability a



128

00:08:29,470 --> 00:08:30,690

false and false.



129

00:08:30,760 --> 00:08:34,080

The result of this expression is going to be assigned to this valuable.



130

00:08:34,270 --> 00:08:40,930

And then I actually create it and if else statement here first of all I specify that if false and false



131

00:08:40,930 --> 00:08:44,860

variable has the value of true then execute this line of code here.



132

00:08:44,920 --> 00:08:51,610

If the value of this false and false variable is true execute this line of code here and else.



133

00:08:51,700 --> 00:08:58,180

If the value of these are false and false value bet is false then execute this line of code here.



134

00:08:58,180 --> 00:08:58,970

OK.



135

00:08:59,200 --> 00:09:01,040

So hopefully that makes sense.



136

00:09:01,090 --> 00:09:03,960

And let's actually run our project and see what happens.



137

00:09:04,030 --> 00:09:04,520

OK.



138

00:09:04,600 --> 00:09:09,260

As you can see now our application is actually running on this emulator here.



139

00:09:09,430 --> 00:09:14,190

And as you can see the value of this false and false variable is actually false.



140

00:09:14,200 --> 00:09:14,720

OK.



141

00:09:14,790 --> 00:09:17,060

Because this checkbox is actually checked.



142

00:09:17,080 --> 00:09:23,830

So because this checkbox is actually checked then we can actually conclude that the value of these are



143

00:09:23,860 --> 00:09:26,640

false and false value but is actually false.



144

00:09:26,680 --> 00:09:29,940

So the value so the result of this expression is false.



145

00:09:29,970 --> 00:09:33,640

Ok false and false results in a false value.



146

00:09:33,640 --> 00:09:40,390

So let's actually comment out again these are this if else statement here because I want to show you



147

00:09:40,390 --> 00:09:45,940

another way in order to write this code so see x files and files.



148

00:09:45,940 --> 00:09:54,380

Yes that's checked and I put in a part of brackets here false and false.



149

00:09:54,520 --> 00:09:55,600

Question mark.



150

00:09:55,710 --> 00:10:00,010

True otherwise false.



151

00:10:00,040 --> 00:10:07,030

So here I am saying that if the value of this false and false value but is true then assign the value



152

00:10:07,030 --> 00:10:08,790

of this the value of truth to this.



153

00:10:08,830 --> 00:10:10,110

I said checked my faith.



154

00:10:10,210 --> 00:10:13,640

Otherwise assign the value false to the six that checked method.



155

00:10:13,670 --> 00:10:13,980

OK.
