1

00:00:00,360 --> 00:00:07,800

So now as you can see here we have an actually of Ordnung here and it says many items should specify



2

00:00:07,800 --> 00:00:14,880

a title and this means that if our application is not actually able to load this vector image it is



3

00:00:14,880 --> 00:00:20,540

going to actually load this title for our menu option for our menu button.



4

00:00:20,550 --> 00:00:26,140

So let's actually specify at hightails So here I can just type in title and then I can choose this attribute.



5

00:00:26,250 --> 00:00:32,190

And here I can just say that the title is going to be settings or who is sitting.



6

00:00:33,240 --> 00:00:37,180

OK so now as you can see here the warning is gone.



7

00:00:37,350 --> 00:00:40,590

And now let's actually create our preferences file.



8

00:00:40,590 --> 00:00:42,090

Inside our project.



9

00:00:42,090 --> 00:00:46,280

So now just a selectees rest folder here.



10

00:00:46,380 --> 00:00:52,450

Right click on it new and then just selectees and roit resource directory and read the source file.



11

00:00:52,470 --> 00:00:54,690

Excuse me just excuse me.



12

00:00:54,690 --> 00:00:57,560

Let's actually move through this process again.



13

00:00:57,600 --> 00:01:02,160

Right click on these arrests for the new and then choose Android resource wide.



14

00:01:02,320 --> 00:01:02,890

OK.



15

00:01:03,000 --> 00:01:11,240

And for the name just type in here cuius underline preferences.



16

00:01:11,650 --> 00:01:12,120

OK.



17

00:01:12,220 --> 00:01:14,230

Is underlined preferences.



18

00:01:14,610 --> 00:01:21,550

And now for to actually for the resource type choose ASML as you can see here.



19

00:01:21,630 --> 00:01:24,440

And as you can see here the root element is preference.



20

00:01:24,450 --> 00:01:29,170

Screen the source said is main and the directory name is exit right.



21

00:01:29,330 --> 00:01:29,910

And actually.



22

00:01:29,940 --> 00:01:30,620

OK.



23

00:01:31,140 --> 00:01:37,560

As you can see here now we have a new directory called ASML and we have this quiz underline preferences



24

00:01:37,560 --> 00:01:38,420

that example.



25

00:01:38,610 --> 00:01:42,250

So this image here is actually it like an activity.



26

00:01:42,420 --> 00:01:44,600

And now let me show you what this does here.



27

00:01:44,820 --> 00:01:48,500

So now let me open the emulator here.



28

00:01:48,500 --> 00:01:49,490

Disqus application.



29

00:01:49,500 --> 00:01:55,170

And now if we click on this a setting button here as you can see now this activity is open.



30

00:01:55,170 --> 00:02:01,080

Right here you can see these options and this activity is this one right this is the preferences.



31

00:02:01,110 --> 00:02:07,320

We can actually use these options in order to specify and in order to specify the actually the settings



32

00:02:07,320 --> 00:02:08,530

of our application.



33

00:02:08,610 --> 00:02:14,610

For example the types of animal that you want to be used inside Yamla inside the keys for example the



34

00:02:14,610 --> 00:02:20,070

number of cases that you choose by given color for example I can specify the background color for example



35

00:02:20,100 --> 00:02:20,910

black.



36

00:02:21,330 --> 00:02:27,540

And then I can specify the quarries the front of our Barkleys application as you can see here the text



37

00:02:27,870 --> 00:02:33,330

of our buttons as you can see here are all going to be if their phones are going to be changed according



38

00:02:33,330 --> 00:02:35,090

to these phones.



39

00:02:35,430 --> 00:02:40,860

Now if I actually click on dispatch button here as you can see here the background color is black.



40

00:02:41,040 --> 00:02:41,960

Right.



41

00:02:42,000 --> 00:02:44,310

So hopefully that makes sense.



42

00:02:44,330 --> 00:02:46,730

And now let's actually go inside this quiz.



43

00:02:46,890 --> 00:02:49,480

Go inside these quis briefness is that exemplified.



44

00:02:49,830 --> 00:02:55,710

And then click on a text here at the bottom as you can see we have this design tab and we have this



45

00:02:55,980 --> 00:02:58,510

text tab here at the bottom right.



46

00:02:58,530 --> 00:03:05,400

So just select it takes tab and now let's actually double click on the squeeze on the line preferences



47

00:03:05,400 --> 00:03:12,150

that XML file as you can see here just double click on these tab in order to make this area wider and



48

00:03:12,180 --> 00:03:18,090

inside his preference screen as you can see we can put our own logic here for the settings activity.



49

00:03:18,240 --> 00:03:23,610

So now I'm going to paste them some lines of code here and then I'm going to explain to you what's going



50

00:03:23,610 --> 00:03:24,430

on here.



51

00:03:24,750 --> 00:03:28,900

So as you can see here these are the lines of code that I pasted here.



52

00:03:28,920 --> 00:03:29,440

Right.



53

00:03:29,440 --> 00:03:36,210

If you have a list preference and as you can see here the entries are number of guesses list and the



54

00:03:36,260 --> 00:03:41,990

entry values are again a number of cases least we had which we haven't provided the values yet and that



55

00:03:42,000 --> 00:03:45,350

he is setting's underline number of guesses.



56

00:03:45,570 --> 00:03:48,810

And as you can see here the title is number of guesses title.



57

00:03:48,810 --> 00:03:51,120

So we have our strange resource.



58

00:03:51,120 --> 00:03:54,830

So let's actually open our emulator in order to show you this here.



59

00:03:54,840 --> 00:03:55,860

So just click on this.



60

00:03:55,860 --> 00:04:01,620

If I actually click on the settings here as you can see now I am actually creating this list here I



61

00:04:01,620 --> 00:04:07,590

am creating this option here number of guesses as you can see the title is number of guesses and we



62

00:04:07,590 --> 00:04:08,620

have this description.



63

00:04:08,620 --> 00:04:11,680

Show two four or six guess options.



64

00:04:11,730 --> 00:04:17,010

As you can see here this is the description and if I click on it as you can see we have these entries



65

00:04:17,280 --> 00:04:22,400

so the entries as you can see here are the values that we are going to show to the user.



66

00:04:22,530 --> 00:04:28,250

OK those entries are actually only useful for showing them to the user.



67

00:04:28,380 --> 00:04:31,060

So for example we have 2 4 6.



68

00:04:31,110 --> 00:04:37,680

So we're going to show those values to 4 6 through the user and we have also entry values which is very



69

00:04:37,680 --> 00:04:38,450

important.



70

00:04:38,490 --> 00:04:42,270

This is going to be these values are going to be the actual values.



71

00:04:42,270 --> 00:04:49,030

So again because we are just specifying the number of desires we can use the entries or into the values



72

00:04:49,060 --> 00:04:50,220

into these values the same.



73

00:04:50,220 --> 00:04:55,810

So 2 4 6 and the key is actually setting underline number of cases.



74

00:04:55,810 --> 00:05:03,180

So it is very important that we specify a key for our least preference here because of it when we are



75

00:05:03,180 --> 00:05:10,470

actually coding our application inside our main activity that Java or other dhaba files we must actually



76

00:05:10,620 --> 00:05:14,100

use this key in order to reverse this list preference.



77

00:05:14,520 --> 00:05:18,770

So this is really important that you actually provide Actually this is like an ID.



78

00:05:18,950 --> 00:05:19,610

OK.



79

00:05:19,890 --> 00:05:21,210

And if you have a title.



80

00:05:21,210 --> 00:05:25,310

So I already talked about this title so if I clicked on this cancel here.



81

00:05:25,350 --> 00:05:31,350

Now you can see this is the total number of guesses and show two four or six just options.



82

00:05:31,350 --> 00:05:33,140

This is actually the description.



83

00:05:33,300 --> 00:05:39,890

So as you can see this is the sum of the attributes and we have this persistent attribute So what is



84

00:05:39,890 --> 00:05:44,510

this persistent attribute this persistent attribute is going to determine for example if I actually



85

00:05:44,900 --> 00:05:45,290

said it.



86

00:05:45,290 --> 00:05:48,060

Number four here number of cases is 4.



87

00:05:48,350 --> 00:05:53,450

As you can see this if you click on dispatch button here now as you can see the number of cases are



88

00:05:53,450 --> 00:05:54,400

four right.



89

00:05:54,440 --> 00:06:01,190

And this persistent attribute is going to help to save these settings to the shared preferences.



90

00:06:01,190 --> 00:06:04,240

So for example if they actually delete.



91

00:06:04,310 --> 00:06:10,340

For example if I close this application and now if I want to for example open this application here



92

00:06:10,400 --> 00:06:15,490

again as you can see here but this is that application right.



93

00:06:15,740 --> 00:06:19,280

And now as you can see the settings are actually saved.



94

00:06:19,610 --> 00:06:26,390

And that's the job of this persistent attribute this persistent attribute is going to actually save



95

00:06:26,390 --> 00:06:32,570

those settings to the shared preferences so that whenever an application is actually run or running



96

00:06:32,870 --> 00:06:40,800

for the for the next time you can actually read those values to settings from the shared preferences.



97

00:06:40,800 --> 00:06:49,610

So this is very important that you specify a persistent attribute for your Actually for your list programs



98

00:06:49,640 --> 00:06:52,580

or other components inside this preference screen.



99

00:06:52,840 --> 00:06:53,390

OK.



100

00:06:53,440 --> 00:06:58,880

Because it's going to actually save these settings to the shared preferences.



101

00:06:59,120 --> 00:07:01,000

So true persistent true.



102

00:07:01,280 --> 00:07:07,820

And we have our default values so if we don't actually provide our value for our For example number



103

00:07:07,820 --> 00:07:11,060

of cases the default value is going to be number four right.



104

00:07:11,210 --> 00:07:12,630

So the default value is four.



105

00:07:12,880 --> 00:07:18,670

And now we need to actually provide some values for the entries and the values title and summary inside



106

00:07:18,670 --> 00:07:22,390

there for example at a resources or for example is resources.



107

00:07:22,670 --> 00:07:25,390

So now let's actually open our project structure.



108

00:07:25,610 --> 00:07:33,930

So now just click on View tool windows and then click on project and then here inside these values folder.



109

00:07:34,010 --> 00:07:38,240

Just double click on these strings that they send here as you can see.



110

00:07:38,270 --> 00:07:43,970

And now let's actually pro-white some string resources here that actually provide some string values



111

00:07:44,240 --> 00:07:46,110

here and here.



112

00:07:46,190 --> 00:07:50,930

Let's actually go inside the squeeze underline preferences that is him here.



113

00:07:50,960 --> 00:07:52,980

Again as you can see here.



114

00:07:53,120 --> 00:07:56,450

The first one is the total number of guesses total right.



115

00:07:56,450 --> 00:08:00,770

So let's actually copy this value a number of guesses title.



116

00:08:01,190 --> 00:08:08,040

And now let's actually go again inside the streams that exemplified and actually create a string the



117

00:08:08,180 --> 00:08:08,670

here.



118

00:08:08,750 --> 00:08:11,700

And the name is going to be number of cases title.



119

00:08:11,930 --> 00:08:18,860

And now let's actually close this tag and here for this string resource I can actually provide the value



120

00:08:19,810 --> 00:08:20,420

here.



121

00:08:20,420 --> 00:08:23,440

Let's actually open our emulator as you can see here.



122

00:08:23,540 --> 00:08:25,640

The title is number of guesses right.



123

00:08:25,640 --> 00:08:35,170

So here again to say PIN number number of guesses number of guesses.



124

00:08:35,300 --> 00:08:35,930

Right.



125

00:08:36,030 --> 00:08:41,920

So now let's actually go again inside this quiz quiz underlying preferences are the example.



126

00:08:42,120 --> 00:08:46,020

And here we have another string value number of guesses description.



127

00:08:46,020 --> 00:08:52,860

So let's copy this value here and now let's actually go inside the string that is modified.



128

00:08:52,950 --> 00:08:56,530

And here let's actually create another string rissoles.



129

00:08:56,640 --> 00:08:57,850

So strange.



130

00:08:58,170 --> 00:09:03,900

And for the name just paste that value here a number of cases description and then close the stack here.



131

00:09:04,190 --> 00:09:08,500

So now I actually double click on the tab here in order to make his area wider.



132

00:09:08,880 --> 00:09:12,130

So far the value is actually open or emulator again here.



133

00:09:12,150 --> 00:09:19,250

So the value so for the description as you can see here is just typing show two four or six just options.



134

00:09:19,260 --> 00:09:31,210

So here I can just type in schul to 4 or six gifts options right.



135

00:09:31,210 --> 00:09:37,660

This is going to be the description the Samadi as you can see here and now let's actually go again inside



136

00:09:37,660 --> 00:09:40,490

the squeeze underline preferences that is the.



137

00:09:40,510 --> 00:09:41,480

As you can see here.



138

00:09:41,710 --> 00:09:46,400

Now the arrow is gone and we also need to provide some values here.



139

00:09:46,750 --> 00:09:50,650

As you can see at sign at a slash number of guesses at least.



140

00:09:50,710 --> 00:09:54,640

And as you can see here Vidi to actually provide another example right here.



141

00:09:54,640 --> 00:09:56,830

So let's open our project structure.



142

00:09:56,830 --> 00:09:59,920

So just click on this view tool windows project.
