1

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

So now I'm going to paste in some lines of code here inside this class.



2

00:00:05,040 --> 00:00:09,420

So before the end in calibers of this class I'm going to paste in some lines of code and then I'm going



3

00:00:09,420 --> 00:00:12,590

to explain to you what's going on here.



4

00:00:12,630 --> 00:00:18,660

So as you can see here these are the lines of code that I pasted here and now as you can see this is



5

00:00:18,660 --> 00:00:19,590

actually a method.



6

00:00:19,800 --> 00:00:27,030

So public voit as you can see the access modify it is Popbitch the return type of the Smurfette is void



7

00:00:27,390 --> 00:00:31,740

and the name of this method is modify each type of inquiries.



8

00:00:31,980 --> 00:00:37,920

So as you can see this bifurcation accepts an argument of type shared preferences and the name of this



9

00:00:38,010 --> 00:00:40,010

argument is shared preferences.



10

00:00:40,500 --> 00:00:42,990

And as you can see are actually opened and closed.



11

00:00:42,990 --> 00:00:45,080

This effort by using these curly braces.



12

00:00:45,090 --> 00:00:49,800

So now let's actually go inside the curly braces of this method and let's see what's going on here.



13

00:00:49,800 --> 00:00:56,810

So first of all let me tell you that the purpose of this method is to actually modify the type of animals



14

00:00:56,820 --> 00:00:58,810

that you want to have inside our quiz.



15

00:00:58,890 --> 00:01:03,430

So now let me show you the emulator as you can see it this is our emulator.



16

00:01:03,430 --> 00:01:07,780

And for example now we can actually play with Disqus here.



17

00:01:07,890 --> 00:01:10,840

But now let's let's actually go inside the settings activity.



18

00:01:11,040 --> 00:01:14,080

And now here as you can see we have this item animals right.



19

00:01:14,130 --> 00:01:16,980

So just click on it and here.



20

00:01:17,010 --> 00:01:24,210

Let's actually assume that I want to only have wild animals inside my quiz so I just need to check these



21

00:01:24,300 --> 00:01:26,710

wild animals here as you can see.



22

00:01:26,920 --> 00:01:31,860

And now I just need to click on OK and then actually click on back here.



23

00:01:32,910 --> 00:01:38,820

As you can see here now the quiz is going to have only actually wild animals.



24

00:01:38,820 --> 00:01:41,240

So for example this is actually a leopard.



25

00:01:41,700 --> 00:01:44,480

And now the next image is going to be again a wild animal.



26

00:01:44,480 --> 00:01:47,230

For example this is a dog right.



27

00:01:47,250 --> 00:01:54,150

So now as you can see by actually changing the settings and actually changing the type of animals that



28

00:01:54,240 --> 00:02:00,520

you want to have in say the quiz we can actually determine the type of animals that we can have inside



29

00:02:00,520 --> 00:02:01,340

the squeeze.



30

00:02:01,380 --> 00:02:03,630

So that's the purpose of this method here.



31

00:02:03,750 --> 00:02:09,380

When I actually change the type of the animals here as you can see this Mfat here is going to be called.



32

00:02:09,510 --> 00:02:13,920

So now as you can see let's actually go inside the curly braces of the Smurfette.



33

00:02:14,040 --> 00:02:22,240

So first as you can see I actually fed to this this valuable animal types inquiries so analysis should



34

00:02:22,270 --> 00:02:23,690

go inside our class.



35

00:02:23,690 --> 00:02:25,760

Let's scroll to the top of the file here.



36

00:02:26,030 --> 00:02:33,110

As you can see we actually created this set here as you can see this is actually a set of string values



37

00:02:33,620 --> 00:02:37,040

and the name of our set is animal types in quiz.



38

00:02:37,250 --> 00:02:39,910

So not essentially just add up.



39

00:02:40,310 --> 00:02:42,550

Let's actually look at this line of code here.



40

00:02:42,560 --> 00:02:44,040

He had actually said right.



41

00:02:44,060 --> 00:02:50,150

I told you about it before that sets cannot have duplicated values right.



42

00:02:50,180 --> 00:02:56,240

So now as you can see let's scroll down here and let's actually go back into our method here.



43

00:02:56,270 --> 00:02:57,070

As you can see here.



44

00:02:57,080 --> 00:03:00,950

So animal types inquiries assignment operator.



45

00:03:00,950 --> 00:03:03,830

So here I am actually initializing this set.



46

00:03:03,830 --> 00:03:04,330

Right.



47

00:03:04,490 --> 00:03:11,960

So here I am referring to this share's preferences argument that I get from Smurfette does get strength



48

00:03:11,960 --> 00:03:12,300

set.



49

00:03:12,320 --> 00:03:16,490

So as you can see here I am calling this method get string set.



50

00:03:16,520 --> 00:03:21,260

So by calling the smith and I can actually get a set of string values.



51

00:03:21,260 --> 00:03:28,670

So now let's scroll to the top of the file here as you can see we actually have actually a set of string



52

00:03:28,670 --> 00:03:33,440

values as you can see here a set of string values and the name is animal types in quotes.



53

00:03:33,590 --> 00:03:35,820

So now let's scroll down here.



54

00:03:36,620 --> 00:03:39,980

As you can see I am actually calling this method get string set.



55

00:03:39,980 --> 00:03:44,060

So this Smurfette is going to give us a set of values.



56

00:03:44,210 --> 00:03:47,930

So for the arguments as you can see here we need to specify the key.



57

00:03:47,930 --> 00:03:52,820

So the key is main activity that animals underline type.



58

00:03:52,970 --> 00:03:58,010

And now it's actually legal in say the main activity file here as you can see inside this main activity



59

00:03:58,010 --> 00:04:00,210

class in line number 17.



60

00:04:00,230 --> 00:04:02,550

I actually created this constant here.



61

00:04:02,720 --> 00:04:03,430

Right.



62

00:04:03,470 --> 00:04:07,140

And as you can see the data type is strengthen Aimee's.



63

00:04:07,280 --> 00:04:09,520

Underline type assignment operator.



64

00:04:09,620 --> 00:04:14,870

And inside the double quotes you can see that we put these values settings underline animal type.



65

00:04:14,900 --> 00:04:20,570

So this is the key that is specified inside the squeeze on the left preferences that example as you



66

00:04:20,570 --> 00:04:21,470

can see here.



67

00:04:21,470 --> 00:04:26,630

So here we have actually a multi-select a multi-select list preference as you can see.



68

00:04:26,780 --> 00:04:32,630

So now you can see that the entries are type of animals the interest values as you can see here type



69

00:04:32,630 --> 00:04:33,990

of animals values.



70

00:04:34,010 --> 00:04:39,910

So let's actually hold the Comanche on a keyboard and then click on these entries here as you can see



71

00:04:39,920 --> 00:04:41,570

this is actually the entries.



72

00:04:41,630 --> 00:04:46,310

So these values are the values that we are going to show to the user right.



73

00:04:46,340 --> 00:04:48,860

Wild animals or tame animals.



74

00:04:49,070 --> 00:04:52,700

And if I show you the emulator as you can see these are the two values.



75

00:04:52,790 --> 00:04:54,710

Wild animals or tame animals.



76

00:04:54,830 --> 00:05:00,380

And let's actually go back into our quiz Underland preferences that exemplified and we have also into



77

00:05:00,380 --> 00:05:01,190

values.



78

00:05:01,190 --> 00:05:06,220

So these three values are the actual values that we are going to work with here.



79

00:05:06,230 --> 00:05:12,440

As you can see so I actually hold the comments on my keyboard and then I clicked on that and three values.



80

00:05:12,440 --> 00:05:14,530

And here is here is the radius right.



81

00:05:14,600 --> 00:05:17,900

You can see that a type of animals values.



82

00:05:18,080 --> 00:05:22,140

And as you can see white underline any mouse or paint on the animals.



83

00:05:22,280 --> 00:05:26,340

So these are the values that we are going to work with from our job coats.



84

00:05:26,510 --> 00:05:27,700

So let's go back into our quiz.



85

00:05:27,720 --> 00:05:34,480

Underland preferences that exemplified and here you can see that the key is settings underline and impulse



86

00:05:34,490 --> 00:05:35,250

type.



87

00:05:35,270 --> 00:05:40,910

So I created this key here so that I can actually interact with this multi-select this preference from



88

00:05:40,910 --> 00:05:41,430

my job.



89

00:05:41,450 --> 00:05:45,670

Cote's so inciters main activity here main activity of a fight.



90

00:05:45,710 --> 00:05:51,890

I actually created this key here and then I assigned this key to this constant so that when ever I want



91

00:05:51,890 --> 00:05:55,580

to use this key I can actually refer just to this name here.



92

00:05:55,580 --> 00:05:59,730

Animals on the type Smain activity that animals underling type.



93

00:05:59,780 --> 00:06:05,600

So if I go back into our Actually main activity fragment of the Java file as you can see inside this



94

00:06:05,600 --> 00:06:11,480

class I actually passed this key so that I can actually get this string set here as you can see main



95

00:06:11,480 --> 00:06:13,890

activity that animals type.



96

00:06:14,270 --> 00:06:17,040

And for the default value I passed the value null.



97

00:06:17,090 --> 00:06:17,590

Why.



98

00:06:17,660 --> 00:06:24,110

Because inside the underlying preferences that exemplified I actually specified a default value for



99

00:06:24,110 --> 00:06:26,920

this multi select list preference as you can see here.



100

00:06:26,990 --> 00:06:28,630

Right.



101

00:06:28,830 --> 00:06:32,450

Value is an assignment operator and instead of quotes at St..



102

00:06:32,450 --> 00:06:37,650

Address what this refers to the arrays that exemplified slash type of animals by the use.



103

00:06:37,790 --> 00:06:41,210

And if I hold that control if I hold the comment on my keyboard.



104

00:06:41,210 --> 00:06:45,710

So if you are using a Windows machine just hold the control key on your keyboard and then click on this



105

00:06:45,720 --> 00:06:46,580

value here.



106

00:06:46,820 --> 00:06:51,670

As you can see this is actually the default value type of animals values.



107

00:06:51,710 --> 00:06:53,900

So he's going to use these values here.



108

00:06:53,900 --> 00:06:54,410

Right.



109

00:06:54,470 --> 00:06:59,030

Wild Underland animals or tame Underland and tame underline animals.



110

00:06:59,060 --> 00:07:04,000

So by default both of these types are going to be included in say the keys.



111

00:07:04,100 --> 00:07:04,880

Right.



112

00:07:04,910 --> 00:07:10,500

So for the first time that they use that is actually has installed this application on his or her device.



113

00:07:10,610 --> 00:07:16,480

They can actually see both vile animals and tame animals inside a quiz as you can see here.



114

00:07:16,820 --> 00:07:17,520

Right.



115

00:07:18,040 --> 00:07:21,320

So hopefully that makes sense.



116

00:07:21,490 --> 00:07:26,420

Now let's actually go back into our Actually main activity fragment that of a file.



117

00:07:26,800 --> 00:07:32,530

And here you can see that we are actually getting this thing set here from this key main activity that



118

00:07:32,590 --> 00:07:33,550

animals type.



119

00:07:33,610 --> 00:07:39,330

And for the default value I-PASS the value null and of assigning that string set to these animal types



120

00:07:39,340 --> 00:07:40,850

inquiries valuable.



121

00:07:40,930 --> 00:07:41,470

Right.



122

00:07:41,710 --> 00:07:44,750

So now that's enough for the Smurfette.



123

00:07:44,950 --> 00:07:45,540

OK.



124

00:07:45,610 --> 00:07:49,600

So let's actually I'm going to add some more lines of code here for other functions.



125

00:07:49,600 --> 00:07:54,490

So as you can see if I show you the emulator and if I go to the settings activity as you can see here



126

00:07:54,760 --> 00:07:58,260

we need to provide some logic for this to get on color.



127

00:07:58,270 --> 00:08:03,730

So for example when the user selects the bike it uncolored B to B.



128

00:08:03,730 --> 00:08:05,390

For example white.



129

00:08:05,830 --> 00:08:10,280

And when they click on dispatch button here as you can see now that baculum color is white.



130

00:08:10,360 --> 00:08:11,180

Right.



131

00:08:11,220 --> 00:08:14,740

And they can actually just the animal here.



132

00:08:14,740 --> 00:08:19,480

So let's actually go back into our Android studio and let's actually go inside this class.



133

00:08:19,680 --> 00:08:21,100

Main activity fragment class.



134

00:08:21,100 --> 00:08:26,230

So before the end in curly brace of this class you're going to pay some lines of code and then I'm going



135

00:08:26,230 --> 00:08:28,330

to explain to you what's going on here.
