00:00:00,240 --> 00:00:02,050

Hello this is Martez of course.



2

00:00:02,100 --> 00:00:07,530

And in this story all let's change the Paglen color of our relatively Also inside this componentry section



3

00:00:07,530 --> 00:00:15,210

description relatively out and inside these attributes here you can see that we have this icon view



4

00:00:15,270 --> 00:00:17,360

all attributes and view.



5

00:00:17,460 --> 00:00:23,180

Again if I click on it you can see this list attributes of view all attributes and search for the background



6

00:00:23,250 --> 00:00:24,460

attributes.



7

00:00:24,660 --> 00:00:25,830

So here for this.



8

00:00:25,830 --> 00:00:30,170

Back in an attribute you can see this spot and you can see this from that spot.



9

00:00:30,210 --> 00:00:35,790

If I hover over these attributes or just click on it and here this window is going to be orphant you



10

00:00:35,790 --> 00:00:39,260

can see we have some Papiss click on color top.



11

00:00:39,480 --> 00:00:40,640

And here we can change.



12

00:00:40,680 --> 00:00:41,990

We can select a color.



13

00:00:42,000 --> 00:00:45,900

So for example we can change click on color axent right.



14

00:00:46,230 --> 00:00:51,390

If you want to you can change the color here or here it says add new resource right.



15

00:00:51,390 --> 00:00:58,840

Just click on it and here just click on new color value and for example we can select a new color.



16

00:00:58,840 --> 00:01:01,390

Here we have we have red color.



17

00:01:01,410 --> 00:01:03,240

We have Hallward red light.



18

00:01:03,300 --> 00:01:05,710

We can just choose this color and then click on OK.



19

00:01:05,940 --> 00:01:08,310

So now the background color is changed.



20

00:01:08,460 --> 00:01:15,660

So now let's add our linearly out horizontal into our little lives inside this palette section.



21

00:01:15,660 --> 00:01:22,860

Click on layouts and just click on linearly or horizontal and just drag it here into our relatively



22

00:01:22,860 --> 00:01:25,100

out OK.



23

00:01:25,320 --> 00:01:30,340

So let's put it here and now are to select this linearly as horizontal.



24

00:01:30,360 --> 00:01:34,220

Let's close this search and for the lay out of it.



25

00:01:34,290 --> 00:01:41,310

Let's assign the value of content to this for the height assigned the value of content for this linearly



26

00:01:41,310 --> 00:01:42,090

and horizontal.



27

00:01:42,180 --> 00:01:42,960

OK.



28

00:01:43,080 --> 00:01:45,520

Now literally out of with as much apparent.



29

00:01:45,870 --> 00:01:51,580

So now let's add some buttons to our linearly as horizontal inside this palette section and all.



30

00:01:51,580 --> 00:01:55,140

And at the bottom two are linearly at all isn't.



31

00:01:55,160 --> 00:02:00,740

So here we have the spot and let's change the takes of this button to button one.



32

00:02:01,010 --> 00:02:03,040

And the president of your keyboard.



33

00:02:03,590 --> 00:02:07,520

And here you can see that the layout of our button is wrapped content.



34

00:02:07,550 --> 00:02:08,210

Right.



35

00:02:08,660 --> 00:02:11,550

But the layout weight is number one.



36

00:02:11,570 --> 00:02:14,980

Just delete this number one and then present it to the key on your keyboard.



37

00:02:15,260 --> 00:02:16,580

So I thought what about this.



38

00:02:16,580 --> 00:02:22,280

Lay out great leader for now let's just click on this view all attributes in order to see list attributes



39

00:02:22,280 --> 00:02:23,030

here.



40

00:02:23,090 --> 00:02:28,760

Let's add another part into our linearly or horizontal and below this pattern here inside this componentry



41

00:02:28,760 --> 00:02:29,690

section.



42

00:02:29,690 --> 00:02:37,460

So just select a spot in change that takes up the spot into Potin to and delete the value of this play



43

00:02:37,470 --> 00:02:39,810

out we lay out a wait actually.



44

00:02:40,390 --> 00:02:43,950

And here you can see that the last bit which is rap content.



45

00:02:44,080 --> 00:02:48,790

Let's add another button to this linearly horizontal inside this linearly horizontally so you can see



46

00:02:48,790 --> 00:02:56,230

that these blue lines are actually guiding us that very we don't exactly put our patents or just put



47

00:02:56,230 --> 00:03:05,560

it here and here at Selecta spotted for the text choose a button of free and then precedented on your



48

00:03:05,560 --> 00:03:09,110

keyboard and the lay out weight should be nothing.



49

00:03:10,140 --> 00:03:17,330

So here you can see that we have these buttons but it is these buttons are this organized.



50

00:03:17,370 --> 00:03:20,660

I don't like how these buttons are actually organized.



51

00:03:20,970 --> 00:03:25,500

So in order to solve this problem we need to assume just assume.



52

00:03:25,500 --> 00:03:34,740

Imagine imagine that this linearly at horizontal is actually divided into three parts because we have



53

00:03:34,740 --> 00:03:37,080

only five buttons free buttons right.



54

00:03:37,110 --> 00:03:44,280

So if you imagine that only nearly horizontal is divided into three parts each button should take one



55

00:03:44,280 --> 00:03:45,100

part.



56

00:03:45,400 --> 00:03:51,910

OK the beat of each button should take one part of this linearly or horizontal.



57

00:03:52,320 --> 00:03:57,960

We don't want to do anything with the height because the height is rock content but you want to solve



58

00:03:58,020 --> 00:04:01,080

the problem of the beat.



59

00:04:01,090 --> 00:04:03,510

So now here we are going to do.



60

00:04:03,790 --> 00:04:05,650

So just select for example.



61

00:04:05,650 --> 00:04:09,920

These buttons hold down inside this componentry section if you find two cities.



62

00:04:09,940 --> 00:04:15,040

All of these patterns you can either hold down the Shift key and select all of them or you can't just



63

00:04:15,190 --> 00:04:16,540

if you're using a Mac.



64

00:04:16,660 --> 00:04:19,970

Just hold down the command key on your keyboard and select each of these buttons.



65

00:04:20,140 --> 00:04:24,890

And if you're using Windows hold down the construction on your keyboard and track each of these buttons.



66

00:04:25,450 --> 00:04:30,500

And here for the layout V we just assign the value zero here.



67

00:04:31,390 --> 00:04:38,410

Because we assumed that our linearly as horizontal is divided into three free parts of our linearly



68

00:04:38,410 --> 00:04:46,320

authority until it's divided into three parts and each part in it should take one part each part in



69

00:04:46,340 --> 00:04:50,310

which should take one part of our linearly or horizontally.



70

00:04:50,530 --> 00:04:54,640

So now we assign the value zero for the layout with our patterns.



71

00:04:54,640 --> 00:04:57,450

Now we have this lay out weight attributes.



72

00:04:57,580 --> 00:05:03,390

So I told you that we have three parts so each button should take one part and we assign the value.



73

00:05:03,390 --> 00:05:09,540

Number one for the button for the Leanna's varied of each button in that holding area horizontally so



74

00:05:09,550 --> 00:05:13,610

just as I did another one here and then press on on your keyboard.



75

00:05:14,050 --> 00:05:21,370

So now you can see that our buttons are now completely organized inside Onelia horizontal.



76

00:05:21,550 --> 00:05:28,420

So this is how you solve the problem of linearly outs in and right whether you want to specify the lay



77

00:05:28,420 --> 00:05:32,980

out Viets or the outside this lay of weight is very usable.



78

00:05:33,060 --> 00:05:40,090

OK so for example I imagine that might lay out linearly at present or is divided into three parts.



79

00:05:40,300 --> 00:05:46,170

And I wanted that each button should take one part of that linearly out horizontal.



80

00:05:46,240 --> 00:05:53,450

So I assign the values 0 to the layout of each bartend and is I assigned to lay out vate value.



81

00:05:53,500 --> 00:05:55,700

Number one for that we have to wait up each button.



82

00:05:55,720 --> 00:06:03,070

So now you can see that our linearly horizontal is actually divided into three parts and each part is



83

00:06:03,070 --> 00:06:05,990

taken by each button here.



84

00:06:06,250 --> 00:06:06,630

Right.



85

00:06:06,640 --> 00:06:08,160

So you learn more about this later.



86

00:06:08,170 --> 00:06:14,680

But here I just wanted to tell you that before we use the persons so we just said for example I said



87

00:06:14,680 --> 00:06:22,810

that assume that this linearly or horizontal or this in the area vertical is for example Davidovits



88

00:06:22,930 --> 00:06:26,420

or the height is for example 100 percent.



89

00:06:26,420 --> 00:06:33,960

And for example we want our button all we want are text views to take for example a 20 percent or that



90

00:06:33,960 --> 00:06:40,990

pattern to take 25 percent dispersants is not used anymore in Android studio and it can actually show



91

00:06:40,990 --> 00:06:48,130

you a compiler error if you use percent for the base attributes of your for example but in all your



92

00:06:48,130 --> 00:06:48,930

layouts.



93

00:06:49,150 --> 00:06:52,050

So for example here we cannot say 50 percent is going to.



94

00:06:52,300 --> 00:06:57,850

If you want to run your app can actually show you a compiler error for that here.



95

00:06:57,950 --> 00:06:59,440

Here is the formula.



96

00:06:59,710 --> 00:07:06,400

If you are using a linearly out for example a horizontal linearly or a vertical linearly out just as



97

00:07:06,400 --> 00:07:12,880

soon or imagined that that's linearly out is actually divided into a number of parts.



98

00:07:12,940 --> 00:07:14,200

It doesn't really matter.



99

00:07:14,200 --> 00:07:20,500

It depends on your application and how you how many items you want to add into that specific linearly



100

00:07:20,500 --> 00:07:21,240

out.



101

00:07:21,340 --> 00:07:22,570

Just assume that it is.



102

00:07:22,570 --> 00:07:33,490

Imagine it is divided into a number of parts and 40 lay out Viets or lay out height of your for example



103

00:07:33,490 --> 00:07:35,400

of specific items.



104

00:07:35,470 --> 00:07:37,350

Just assign the values here.



105

00:07:37,390 --> 00:07:39,910

I just want to solve the problem of lay out.



106

00:07:40,060 --> 00:07:48,010

So I assign the value 0 to the layout width of each button and here for example here I wanted to for



107

00:07:48,010 --> 00:07:52,730

example my button each button to take each part to take one part.



108

00:07:52,750 --> 00:07:56,450

So I assigned the value number one for the lay out weight of each button.



109

00:07:56,740 --> 00:08:04,780

So here for example you may say that I want to assume or imagine that my linearly or horizontal is divided



110

00:08:04,780 --> 00:08:06,510

into 10 parts.



111

00:08:06,510 --> 00:08:06,820

Right.



112

00:08:06,820 --> 00:08:09,800

You can imagine that you can imagine anything.



113

00:08:10,090 --> 00:08:16,870

So now I am going to imagine that my linearly authorities aren't all is divided into 10 parts and one



114

00:08:16,870 --> 00:08:23,800

of my Bettina's So for example Potten number three I want this patent to take eight parts.



115

00:08:24,190 --> 00:08:26,080

So how you're going to solve this problem.



116

00:08:26,260 --> 00:08:31,200

So in order to solve this problem so use it that we have put in number one but in two we have both in



117

00:08:31,260 --> 00:08:37,660

the bottom three should take eight parts of the vse of the linearly out horizontally.



118

00:08:37,660 --> 00:08:41,070

So in order to solve this problem you just need to select a pattern free.



119

00:08:41,270 --> 00:08:47,930

So the left of should be zero because here we want at the bottom free to take eight parts of the bit



120

00:08:48,220 --> 00:08:49,600

of the linearly and horizontal.



121

00:08:49,720 --> 00:08:53,020

OK so that's why we assign the number 0 to the lay out.



122

00:08:53,470 --> 00:08:59,740

And for the lay out rate instead of number one we just assign the value number 8 and then present until



123

00:08:59,740 --> 00:09:00,910

January.



124

00:09:01,270 --> 00:09:08,940

So now we can see that this part in free is taking eight parts of the linearly out horizontally.



125

00:09:09,310 --> 00:09:10,800

Right.



126

00:09:10,930 --> 00:09:18,490

So now somebody else says OK now I want to imagine that my linearly out to the width of my linear layout



127

00:09:18,520 --> 00:09:27,530

is actually divided into 20 parts and I want my number one to take for example a 10 parts.



128

00:09:27,730 --> 00:09:33,290

So here you can see that bottom number three is eight parts of the 20 parts.



129

00:09:33,320 --> 00:09:39,020

Right and bottom number two is actually taking one part.



130

00:09:39,380 --> 00:09:42,900

So now there are actually 11 parts left.



131

00:09:42,980 --> 00:09:50,880

So we can now say that button number one can take 11 parts and then press on until you on your table.



132

00:09:51,260 --> 00:09:53,870

So you can see that how these layouts change.



133

00:09:53,870 --> 00:09:54,140

Right.



134

00:09:54,140 --> 00:09:56,070

We have number one button free.



135

00:09:56,210 --> 00:09:58,030

So you learn all about it later.



136

00:09:58,040 --> 00:10:04,430

But here I just wanted to actually let you know about the lay out weight and how you are going to design



137

00:10:04,430 --> 00:10:10,590

your layouts later in this course because we're going to create about 90 applications in the scores.



138

00:10:10,790 --> 00:10:17,300

So it is necessary that you learn all about these attributes and how you're going to design your layouts



139

00:10:17,300 --> 00:10:18,100

in this course.



140

00:10:18,440 --> 00:10:21,610

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



141

00:10:21,620 --> 00:10:26,300

I'm going to show you how you can run your application on the Android emulator.



142

00:10:26,300 --> 00:10:27,750

Thank you very much for watching.



143

00:10:27,800 --> 00:10:33,950

If you have any questions about these concepts that I've taught you so far please what's the discussion



144

00:10:33,950 --> 00:10:34,590

in the course.



145

00:10:34,760 --> 00:10:36,870

And then I do my best to answer all of your questions.



146

00:10:37,280 --> 00:10:40,000

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