1

00:00:00,330 --> 00:00:05,460

So now I'm going to paste in a line of code here and then I'm going to explain to you what's going on



2

00:00:05,460 --> 00:00:06,140

here.



3

00:00:06,420 --> 00:00:10,180

So as you can see here this is the line of code that I pasted here.



4

00:00:10,200 --> 00:00:11,730

He asks the question number.



5

00:00:11,760 --> 00:00:18,570

So as you can see here I actually declare that DCX the question number here in line number 43 which



6

00:00:18,570 --> 00:00:19,460

is after it takes.



7

00:00:19,470 --> 00:00:22,990

And then I actually initialized that takes the question number.



8

00:00:22,990 --> 00:00:27,060

Here in line number seventy insight is uncreate view as you can see here.



9

00:00:27,060 --> 00:00:32,530

He asks the question question number and here you referred to the name of that variable.



10

00:00:32,530 --> 00:00:33,840

He asks the question number.



11

00:00:33,930 --> 00:00:35,000

That said text.



12

00:00:35,010 --> 00:00:41,340

So I want to set a text to this DXi question number and as you can see here we need to provide a string



13

00:00:41,340 --> 00:00:44,330

value for these set text Meffert.



14

00:00:44,340 --> 00:00:47,380

So I actually called jet stream method.



15

00:00:47,460 --> 00:00:48,730

As you can see here.



16

00:00:48,750 --> 00:00:54,660

So now if we actually hold the common key on my keyboard and then click on this string in effect here



17

00:00:54,960 --> 00:01:00,380

as you can see now as you can see it gets three Meffert is actually coming from these fragment that



18

00:01:00,420 --> 00:01:02,870

job a file here as you can see here.



19

00:01:02,880 --> 00:01:08,230

So we have this gets through the method and the return value of this method is actually osting value



20

00:01:08,340 --> 00:01:08,880

right.



21

00:01:09,060 --> 00:01:13,930

The return value is going to be of type string and it's going to give us a string value.



22

00:01:13,950 --> 00:01:17,150

Right that's the only job of this string method.



23

00:01:17,160 --> 00:01:23,340

So now if I if you want to you can actually look at the descriptions here and you will get.



24

00:01:23,340 --> 00:01:26,600

You will get an idea about this method.



25

00:01:26,790 --> 00:01:30,990

So let's actually close this file here and we have this thing.



26

00:01:31,030 --> 00:01:33,790

And this is if it actually accepts free arguments.



27

00:01:33,900 --> 00:01:37,410

So let's actually again hold the comment key on a keyboard.



28

00:01:37,410 --> 00:01:42,030

So if you are using a Windows machine hold the control on your keyboard and then click on it's getting



29

00:01:42,180 --> 00:01:42,700

it.



30

00:01:42,930 --> 00:01:46,330

And as you can see here this live it actually accepts some arguments.



31

00:01:46,410 --> 00:01:51,780

The first one is going to be to raise ID which is going to have be an integer.



32

00:01:51,780 --> 00:01:56,750

The second volley is going to be an array of values of type Object.



33

00:01:56,760 --> 00:01:59,760

So you already know about this at here.



34

00:02:00,360 --> 00:02:02,180

And as you can see here.



35

00:02:02,190 --> 00:02:08,120

So let's actually go back inside our main activity fragment that of a file and here as you can see I



36

00:02:08,110 --> 00:02:16,330

actually it's assigned this value as the first argument are thought to think that question on the length



37

00:02:16,350 --> 00:02:17,280

text.



38

00:02:17,280 --> 00:02:21,580

So now let's actually go inside our strings that exemplify.



39

00:02:21,600 --> 00:02:25,440

So now let me show you the structure are the structure of our project.



40

00:02:25,440 --> 00:02:33,150

So that's really kind of view to Lindows and we can project and here DoubleClick and this app folder



41

00:02:33,150 --> 00:02:36,280

here and then DoubleClick and this arrest folder.



42

00:02:36,510 --> 00:02:38,820

And he has definitely shown these values for there.



43

00:02:38,850 --> 00:02:45,230

And then this strength that exemplified so inside these strings that them fight as you can see here



44

00:02:45,240 --> 00:02:48,370

we have this question underlying text string resource.



45

00:02:48,390 --> 00:02:56,980

As you can see here and it says this is animal pearlescent one dollar sign d of person two dollar sign.



46

00:02:57,120 --> 00:03:01,150

So I already told you about these these formats.



47

00:03:01,270 --> 00:03:06,390

This one is going to be the first argument and this one is going to be the second argument.



48

00:03:06,540 --> 00:03:07,260

Right.



49

00:03:07,260 --> 00:03:10,940

So now if I go back and say this me an active man activity fragment here.



50

00:03:10,980 --> 00:03:17,550

So for the first argument as you can see here of this string Merfeld for the first argument of of this



51

00:03:17,550 --> 00:03:20,320

gets string Meffert we need to provide this Thring resource.



52

00:03:20,400 --> 00:03:25,320

So this resource is going to be that stringless source that we have inside studies things that exemplify



53

00:03:25,530 --> 00:03:26,990

question underlying text.



54

00:03:27,030 --> 00:03:31,050

So our thought streams that question underlying text.



55

00:03:31,050 --> 00:03:31,800

Right.



56

00:03:31,830 --> 00:03:38,230

So for the second argument of this gets Thring Mefford as you can see here we have number one.



57

00:03:38,370 --> 00:03:41,360

So what does this number one refer to.



58

00:03:41,580 --> 00:03:47,370

So if we go back inside these strings that exemplified as you can see here I told you that this format



59

00:03:47,370 --> 00:03:54,060

here this dollars these are percent one dollar Sainty is going to be the first argument of these text



60

00:03:54,060 --> 00:03:54,780

value.



61

00:03:55,200 --> 00:03:59,190

And this per cent two dollar sign is going to be the second argument.



62

00:03:59,400 --> 00:04:04,140

So insanity's gets three Meffert inside this main activity affreightment out of a file.



63

00:04:04,230 --> 00:04:09,570

When I assigned the value number one here for the second argument of this string method I said that



64

00:04:09,570 --> 00:04:15,730

this number one is going to be in place of this person to $1 Sainty.



65

00:04:16,040 --> 00:04:16,650

Right.



66

00:04:16,710 --> 00:04:18,130

That is going to be number one here.



67

00:04:18,180 --> 00:04:21,120

Football is about my number one of.



68

00:04:21,450 --> 00:04:23,060

And then it is actually to go back inside.



69

00:04:23,070 --> 00:04:28,320

Our main activity fragment out of a fight here number of animals included increase.



70

00:04:28,380 --> 00:04:36,330

So here inside our Java file as you can see at the top inside Isman activity placement class I actually



71

00:04:36,330 --> 00:04:42,570

created a constant here and I said that that number of animals included included in the quiz which is



72

00:04:42,570 --> 00:04:43,230

number 10.



73

00:04:43,350 --> 00:04:49,570

So we're going to have 10 animals inside Ahlquist So why did I actually put number one here.



74

00:04:49,620 --> 00:04:56,220

As you can see because as you can see here inside this uncreate view for the first time that our application



75

00:04:56,220 --> 00:04:59,550

is actually started disvalue is going to be number one here.



76

00:04:59,550 --> 00:05:04,050

So for example let me show you the emulator as you can see it says this is my number one of 10.



77

00:05:04,050 --> 00:05:12,620

So let me close this application let me close these applications here and now if I actually open this



78

00:05:12,620 --> 00:05:19,040

application here again as you can see again just for the first time that for the first time that this



79

00:05:19,040 --> 00:05:22,470

application is actually started as you can see it says this is LMI number one.



80

00:05:22,490 --> 00:05:26,170

So this rally you always should be one.



81

00:05:26,210 --> 00:05:32,730

So that's why I actually put number one here and this number one is going to be in place of that first



82

00:05:32,790 --> 00:05:39,850

argument that we have here first at this present one dollar sign.



83

00:05:40,290 --> 00:05:45,240

So number one and for the sake of argument we have this number of animals included in inquiries.



84

00:05:45,270 --> 00:05:49,870

So here we have 10 animals as you can see here at the top I specified that we have.



85

00:05:50,010 --> 00:05:53,790

We are going to have ten animals inside our quiz right.



86

00:05:53,940 --> 00:05:56,060

So hopefully that makes sense.



87

00:05:56,220 --> 00:05:59,460

And now you get the idea of that of that formatting.



88

00:05:59,490 --> 00:05:59,940

Right.



89

00:05:59,940 --> 00:06:03,230

First I actually called this object.



90

00:06:03,490 --> 00:06:05,430

The question number that said text.



91

00:06:05,520 --> 00:06:09,840

And then I called this method that we get from the fragment class get strange.



92

00:06:10,020 --> 00:06:14,760

And and as you can see here for the first argument we need to refer to that string the source for the



93

00:06:14,760 --> 00:06:15,510

second argument.



94

00:06:15,540 --> 00:06:19,370

But we are going to specify the first argument of that single source.



95

00:06:19,380 --> 00:06:22,760

As you can see here is a person one dollar sign D.



96

00:06:23,070 --> 00:06:27,510

And for the second argument as against the number of animals including increase this value is going



97

00:06:27,510 --> 00:06:33,180

to be in place of actually this value per cent two dollar sign.



98

00:06:33,510 --> 00:06:38,560

So now you get the idea and hopefully that makes sense.



99

00:06:38,880 --> 00:06:47,150

And now I can just type in here return if you as you can see here.



100

00:06:47,200 --> 00:06:51,270

This uncreate view Meffert needs to return a value of type view.



101

00:06:51,310 --> 00:06:51,990

Right.



102

00:06:52,060 --> 00:06:54,100

So here we created this view here.



103

00:06:54,130 --> 00:06:55,980

And B has done actually.



104

00:06:56,380 --> 00:07:01,350

And we actually worked on that view and we used this if you object here.



105

00:07:01,540 --> 00:07:04,620

And then finally we need to retain this view from the Smurfette.



106

00:07:04,630 --> 00:07:05,910

This is very important.



107

00:07:06,310 --> 00:07:12,130

And now what we are going to do if we're going to ask you to create a listener APTN guest listener here



108

00:07:12,160 --> 00:07:14,780

inside our our class.



109

00:07:14,890 --> 00:07:21,190

So before the end in curly brace of this class here as you can see before the end in calibers of this



110

00:07:21,190 --> 00:07:26,350

main activity frypan class I am going to pasting some more lines of code here and then I'm going to



111

00:07:26,350 --> 00:07:28,850

explain to you what's going on here.
