1

00:00:00,600 --> 00:00:06,570

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



2

00:00:06,570 --> 00:00:07,640

on here.



3

00:00:08,130 --> 00:00:12,590

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



4

00:00:12,660 --> 00:00:16,220

Right now I'm going to explain to you what's going on here.



5

00:00:16,320 --> 00:00:17,290

Exactly.



6

00:00:17,490 --> 00:00:23,280

So now let's actually look at RMF at here as you can see if we have actually a method and the access



7

00:00:23,280 --> 00:00:29,670

modifiers of the Smurfette is public the return type of this method is void and the name of the Smurfette



8

00:00:29,670 --> 00:00:31,770

is modified by different colored.



9

00:00:31,770 --> 00:00:32,360

Right.



10

00:00:32,640 --> 00:00:38,700

And as you can see this method accepts one argument of type shared preferences and the name of this



11

00:00:38,700 --> 00:00:41,030

argument is shared preferences.



12

00:00:41,070 --> 00:00:46,380

So let's actually go inside the curly braces of the Smurfette And let's see what's going on here.



13

00:00:46,770 --> 00:00:53,130

So in line number four hundred and seventy three as you can see if we have actually of the bell and



14

00:00:53,130 --> 00:00:59,460

the name of this variable is actually back in color and the date or type of this variable is string.



15

00:00:59,820 --> 00:01:06,630

And then I put an assignment operator here and then I referred to the name of this argument shared preferences



16

00:01:06,780 --> 00:01:08,820

that gets strange.



17

00:01:08,820 --> 00:01:12,120

So here I'm actually calling this method and this is shared preferences.



18

00:01:12,240 --> 00:01:16,900

Main activity does cuius underline it and underline color.



19

00:01:17,010 --> 00:01:22,530

So here I am actually calling this constant that we have inside the main activity our job.



20

00:01:22,710 --> 00:01:26,560

So now let's actually go inside the main activity that are filed here as you can see here.



21

00:01:26,580 --> 00:01:30,980

Inside this class main activity we have this key here right.



22

00:01:30,990 --> 00:01:35,660

Public static final sprint cuius on the line Bigler underline color.



23

00:01:35,670 --> 00:01:42,120

So this is actually a constant that holds this cheap as you can see here of actually assigned this value



24

00:01:42,120 --> 00:01:44,430

which is of types 3 into this constant.



25

00:01:44,430 --> 00:01:49,380

So this is the key settings underline quis Underland by going on on the line color.



26

00:01:49,380 --> 00:01:53,150

So if I actually go inside the class Underland preferences that is then on file.



27

00:01:53,220 --> 00:01:57,120

Now you can see that we have actually at least preference here.



28

00:01:57,240 --> 00:01:58,110

Right.



29

00:01:58,680 --> 00:02:02,250

And the entries is actually at site a slash colors.



30

00:02:02,370 --> 00:02:05,390

And if I actually hold the command key on my keyboard.



31

00:02:05,430 --> 00:02:09,930

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



32

00:02:10,230 --> 00:02:14,820

value here as you can see we have this stunning area here.



33

00:02:14,850 --> 00:02:16,690

So here we have the colors.



34

00:02:16,710 --> 00:02:21,190

So as you can see here this value is the value that we specify here as the entries.



35

00:02:21,210 --> 00:02:21,800

Right.



36

00:02:21,870 --> 00:02:27,090

So now as you can see we have these values and these are the values that we're going to show to the



37

00:02:27,090 --> 00:02:27,660

user.



38

00:02:27,870 --> 00:02:33,360

And if we actually show you the emulator here and if I actually click on these settings here now if



39

00:02:33,360 --> 00:02:39,180

I click on these two specular color as you can see we are actually showing these values white black



40

00:02:39,240 --> 00:02:43,500

green red blue yellow as the values that you want to show to the user.



41

00:02:43,590 --> 00:02:49,660

And now let's go back inside our quiz on the alleged preferences that exemplified and for the interest



42

00:02:49,730 --> 00:02:55,560

values the also refers to this value as sign is an a slash colors.



43

00:02:55,590 --> 00:03:00,600

So if we actually hold the comment on my keyboard and then click on this value here as you can see again



44

00:03:00,840 --> 00:03:07,710

we are again using these values as the actually exact values that we want to actually work with.



45

00:03:07,740 --> 00:03:08,230

Right.



46

00:03:08,370 --> 00:03:10,780

So we actually have these values.



47

00:03:10,830 --> 00:03:13,830

White black green red blue yellow.



48

00:03:14,190 --> 00:03:17,980

And let's actually go back into our quiz underline preferences that exemplified.



49

00:03:18,240 --> 00:03:24,700

And the key is settings underline quick underline Bagenal underline color and the title is this value



50

00:03:24,740 --> 00:03:25,620

to going on color.



51

00:03:25,620 --> 00:03:30,930

So if I actually hold the comment on my keyboard and if you are using a Windows machine just hold the



52

00:03:30,930 --> 00:03:35,730

control on your keyboard and then click on this value as you can see we have this value here too.



53

00:03:35,760 --> 00:03:37,110

Back at non-color.



54

00:03:37,170 --> 00:03:42,760

So let's go back into our quiz Underland preferences them and find if we have this summary.



55

00:03:42,840 --> 00:03:48,690

We have persistence which is actually true and the default value is a value that is specified inside



56

00:03:48,690 --> 00:03:50,650

this string that XML file.



57

00:03:50,820 --> 00:03:53,990

So now let's actually hold the Comanche on our keyboard.



58

00:03:54,000 --> 00:03:58,080

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



59

00:03:58,080 --> 00:04:00,420

different colored black as you can see.



60

00:04:00,420 --> 00:04:06,170

Now I actually created this string the source inside these strings that exemplified.



61

00:04:06,180 --> 00:04:09,890

And now you can see the value which is actually the black color right.



62

00:04:09,900 --> 00:04:15,300

So now if I go back into the squeeze underline preferences for example file you can see that we have



63

00:04:15,300 --> 00:04:21,810

this list preference here and we can actually interact with this preference by using this key here that



64

00:04:21,870 --> 00:04:23,380

you specify here right.



65

00:04:23,610 --> 00:04:26,910

So let's go back into our main activity fragment that of a file.



66

00:04:27,590 --> 00:04:35,310

And now you can see that we are actually getting these values shared preferences that get strange you



67

00:04:35,340 --> 00:04:40,680

are getting the value by using this key you are getting the value that is actually saved through the



68

00:04:40,680 --> 00:04:42,870

shared preference shares preferences.



69

00:04:42,870 --> 00:04:48,860

For example the value can be for example Blache the value can be white green red blue yellow.



70

00:04:48,990 --> 00:04:54,120

So if you are getting that value by using this key main activity that quiz Underland by an underlined



71

00:04:54,120 --> 00:05:01,440

color and for the default value of the past the value not because we actually actually specified a default



72

00:05:01,440 --> 00:05:05,400

value inside the squeeze preferences that examined file you can see this value here right.



73

00:05:05,520 --> 00:05:08,150

So we don't need to specify that value here.



74

00:05:08,220 --> 00:05:13,500

So we passed the value not for the second argument and here it can actually assign that value to the



75

00:05:13,560 --> 00:05:15,770

background color which is of type string.



76

00:05:16,050 --> 00:05:22,360

And now I actually created a switch statement and I want to actually switch between the values of respect



77

00:05:22,460 --> 00:05:23,750

and color.



78

00:05:23,760 --> 00:05:24,780

So sweet.



79

00:05:24,840 --> 00:05:29,040

And now let's actually go inside the curly braces of the switch statement and let's see what's going



80

00:05:29,040 --> 00:05:29,950

on here.



81

00:05:29,970 --> 00:05:32,340

So if you have subcase statements here.



82

00:05:32,340 --> 00:05:38,840

Here we are saying that case white and this means that if the value of this by green color valuable



83

00:05:38,850 --> 00:05:41,880

which is actually off the upstreams is white right.



84

00:05:41,910 --> 00:05:47,300

If the value of this Speigel uncolored is white then it's going to execute these lines of code here.



85

00:05:47,400 --> 00:05:53,610

First it's going to set a background color of the animalcules linearly out here to white.



86

00:05:53,610 --> 00:05:59,610

So animal Quizon initially out that set back in on color color that white and then here we are actually



87

00:05:59,610 --> 00:06:04,670

iterating over them actually over the bottoms that we have inside our cookies.



88

00:06:04,680 --> 00:06:08,940

So let me actually show you the emulator for example now if you want to change the background color



89

00:06:08,940 --> 00:06:12,540

to white right and now it says the new changes are applied.



90

00:06:12,670 --> 00:06:18,360

And if I click on the spike back button here at the top as you can see now the Paglen color is white



91

00:06:18,440 --> 00:06:19,050

right.



92

00:06:19,080 --> 00:06:24,420

So here we can see the Bagian and color of the buttons as you can see here is blue.



93

00:06:24,690 --> 00:06:29,550

So here and the text of the buttons is actually white.



94

00:06:29,640 --> 00:06:35,630

So now we are actually either over these buttons so linearly of all rows of just spottiness in animal



95

00:06:35,650 --> 00:06:41,100

cuius So it is actually either reading over the values of this trait which which actually holds the



96

00:06:41,100 --> 00:06:43,320

values of linearly out.



97

00:06:43,350 --> 00:06:46,050

And then here we have this for loop here.



98

00:06:46,290 --> 00:06:51,090

And it is actually again it's going to go inside the rows of those buttons and it's going to actually



99

00:06:51,090 --> 00:06:54,950

get the columns which is actually there at the bottom that we have here.



100

00:06:55,200 --> 00:07:01,140

So for columns 0 and this loop here is going to be executed until the value of this column is less than



101

00:07:01,140 --> 00:07:03,840

the value of the child count of that row.



102

00:07:03,900 --> 00:07:09,870

So as you can see here and it's going actually increments the value of this column by 1 each time.



103

00:07:09,950 --> 00:07:12,090

After each execution of this fall.



104

00:07:12,420 --> 00:07:16,130

So here as you can see we are actually getting the bottom inside that specific row.



105

00:07:16,260 --> 00:07:22,770

So Button button here we created our variable of type button and the name is button assignment operator.



106

00:07:23,430 --> 00:07:27,280

And then he realized we are actually testing this object a button object.



107

00:07:27,370 --> 00:07:31,730

And here we are referring to the row that get child at column.



108

00:07:31,890 --> 00:07:32,190

Right.



109

00:07:32,190 --> 00:07:35,850

So in this way we can actually access this button for example.



110

00:07:36,060 --> 00:07:40,980

And then it can actually set the background color of the button to color that blue as you can see.



111

00:07:40,980 --> 00:07:45,780

And here we are setting the text colored off that button to color that white.



112

00:07:45,780 --> 00:07:51,570

And here after this will appear as you can see after the ending curly brace of this world we are setting



113

00:07:51,570 --> 00:07:52,480

some other ideas.



114

00:07:52,570 --> 00:07:55,800

TH The answer that text the text color color that blue.



115

00:07:55,800 --> 00:07:59,430

So here if we actually just the name of this animal for example.



116

00:07:59,430 --> 00:08:03,620

And now as you can see the color is blue the color of the answer is blue right.



117

00:08:03,640 --> 00:08:09,510

To actually answer the text color color that blue she asks the question number the text color color



118

00:08:09,510 --> 00:08:10,920

that black light.



119

00:08:10,920 --> 00:08:14,070

So it can actually set the color actually.



120

00:08:14,070 --> 00:08:21,490

Question number two black and now it's going to have actually a break statement.



121

00:08:21,660 --> 00:08:23,590

And we have also this case black.



122

00:08:23,590 --> 00:08:29,520

So if the value of this valuable baculum color is actually black then it's going to execute this case



123

00:08:29,520 --> 00:08:30,200

statement.



124

00:08:30,190 --> 00:08:32,530

These lines of code inside this case statement.



125

00:08:32,880 --> 00:08:37,970

And now as you can see it's going to actually set the background color of this animal cuius linearly



126

00:08:37,970 --> 00:08:43,920

out to Blache as you can see animal quizz linearly out that set by different color colors that black.



127

00:08:44,160 --> 00:08:49,470

And that here again we actually created a for loop in order to eat right over the values or there actually



128

00:08:49,650 --> 00:08:52,060

values of these laws of spottiness in animal cuius.



129

00:08:52,080 --> 00:08:56,700

So it's going to eat right over them proteins that we have inside our crews as you can see here.



130

00:08:57,060 --> 00:09:01,590

And we actually created a for loop and inner for loop in order to access those buttons.



131

00:09:01,590 --> 00:09:06,090

So again we are actually accessing that button inside that specific row.



132

00:09:06,390 --> 00:09:09,060

And we are actually sitting in the back of the uncolored to yellow.



133

00:09:09,060 --> 00:09:11,740

So let's actually change that I get from color to black.



134

00:09:12,060 --> 00:09:16,450

So by your own color black and now it says new changes are applied.



135

00:09:16,470 --> 00:09:20,120

And if I actually click on the spike button here as you can see the back in uncolored is black.



136

00:09:20,120 --> 00:09:20,650

Right.



137

00:09:20,910 --> 00:09:25,920

So now I can actually set the background color of the buttons to yellow as you can see here.



138

00:09:25,920 --> 00:09:29,130

So a button that said Get on colored colored yellow.



139

00:09:29,490 --> 00:09:34,500

And as you can see if you are sitting there in cut the text color excuse me you are sitting just takes



140

00:09:34,500 --> 00:09:40,070

the color of this button to color that black as you can see here the text color of these buttons is



141

00:09:40,080 --> 00:09:42,070

actually a black right.



142

00:09:42,360 --> 00:09:47,490

And finally we are sitting there thinking the answer to color that white as you can see here.



143

00:09:47,520 --> 00:09:53,340

So if you take just the name of this animal here Dalfin now it says now as you can see here the text



144

00:09:53,340 --> 00:09:54,350

color is white.



145

00:09:54,630 --> 00:10:01,230

And of course that takes the question number and color to test the question number that takes color



146

00:10:01,230 --> 00:10:02,640

to color that white.



147

00:10:02,970 --> 00:10:08,420

And here we have a press statement and we hear we have chased green as you can see here.



148

00:10:08,420 --> 00:10:14,160

So if the value of it is valuable as you can see if the value of this by your own color rowdier is actually



149

00:10:14,160 --> 00:10:14,780

green.



150

00:10:15,090 --> 00:10:17,700

Now is going to execute these lines of code here.



151

00:10:18,030 --> 00:10:19,200

As you can see.



152

00:10:19,200 --> 00:10:23,400

So first it's going to actually set the background and color to green.



153

00:10:23,400 --> 00:10:27,680

So animal cuisine linearly out that set by green color color that's green.



154

00:10:27,680 --> 00:10:29,420

So now let me show you the emulator.



155

00:10:29,480 --> 00:10:31,660

Now let's get you to go inside the city's activity.



156

00:10:32,090 --> 00:10:35,230

And now let's actually go and select this truth.



157

00:10:35,240 --> 00:10:38,360

Back in color and just select green.



158

00:10:38,770 --> 00:10:44,570

Now liturgically can dispatch button here at the top as you can see now the background color is green.



159

00:10:44,610 --> 00:10:50,490

And here we have a full look and here it's going to either read all the values that we have inside these



160

00:10:50,730 --> 00:10:52,300

rows of just buttons in animal keys.



161

00:10:52,310 --> 00:10:55,780

So it's going to iterate over the laws that we have inside the squeeze.



162

00:10:56,040 --> 00:11:00,780

And here we have an inner for loop and this inner for loop is going to iterate over the columns that



163

00:11:00,780 --> 00:11:02,190

we have inside these rows.



164

00:11:02,340 --> 00:11:05,110

So these buttons are actually the columns right.



165

00:11:05,130 --> 00:11:11,970

So for in column and this for a of here is going to be executed until the value of this column is less



166

00:11:11,970 --> 00:11:14,310

than the value of the trial count of the throw.



167

00:11:14,580 --> 00:11:19,500

And it's going to add one value for the value of this color variable after each of each execution of



168

00:11:19,500 --> 00:11:20,380

this for loop.



169

00:11:20,400 --> 00:11:26,020

And here we are actually creating a reference to those buttons that we have here inside these rows.



170

00:11:26,040 --> 00:11:31,350

So bottom part in here we created read a bit of a button and then I put an assignment operator here



171

00:11:31,650 --> 00:11:36,630

and here you are casting this object a button object row that good child column.



172

00:11:36,780 --> 00:11:40,500

And here we are setting the background color to blue as you can see here the background and color of



173

00:11:40,500 --> 00:11:42,350

the buttons as you can see here is blue.



174

00:11:42,390 --> 00:11:48,030

And here we are setting the text color of the buttons to white color that actually white as you can



175

00:11:48,030 --> 00:11:48,380

see here.



176

00:11:48,390 --> 00:11:54,300

But in the text color color that white as you can see here and here finally we are sitting.



177

00:11:54,570 --> 00:11:58,110

Actually take the color of the text the answer to color that white.



178

00:11:58,110 --> 00:12:01,210

So now let me guess the name of this animal as you can see here.



179

00:12:01,290 --> 00:12:04,080

Th the answer colored is actually white right.



180

00:12:04,080 --> 00:12:09,960

Take the takes color of the states and is white and that here is the question number that takes color



181

00:12:09,960 --> 00:12:12,420

is actually color that yellow here is white.



182

00:12:12,420 --> 00:12:19,500

But for our for our own application I chose the value yellow and that I put a brave statement here and



183

00:12:19,500 --> 00:12:21,190

here we have case blue.



184

00:12:21,300 --> 00:12:26,160

So if the value of the background color is actually blue so that it may actually change the background



185

00:12:26,220 --> 00:12:33,060

color to blue here and choose Blue and if I click on this back button here as you can see now that back



186

00:12:33,060 --> 00:12:34,420

in uncolored is blue.



187

00:12:34,680 --> 00:12:40,940

And here we are sitting back in uncolored of this animal Chrisley out to actually blue and Quizon Quizon



188

00:12:41,150 --> 00:12:43,850

out that said back in uncolored color that blue.



189

00:12:44,160 --> 00:12:47,370

And here we created a for loop here as he conceived.



190

00:12:47,430 --> 00:12:52,380

So this fall of here is going to actually eat right over the values of this tree which actually holds



191

00:12:52,440 --> 00:12:55,640

values of probably nearly two rows of spottiness in animalcules.



192

00:12:55,740 --> 00:13:00,590

So it can actually hold the rows of spottiness that we have inside our quiz.



193

00:13:00,750 --> 00:13:05,380

Now it's going to overate even I should iterate over the values that we have in this.



194

00:13:05,640 --> 00:13:08,460

And we have an actually in a for loop.



195

00:13:08,490 --> 00:13:10,290

So again column 0.



196

00:13:10,320 --> 00:13:14,850

So it does fall of here is going to be executed until the value of this column is actually less than



197

00:13:14,850 --> 00:13:17,800

the value of the child count of this row.



198

00:13:18,450 --> 00:13:23,640

And then second I should increment the value of this column by 1 after each execution of this for loop.



199

00:13:23,640 --> 00:13:28,230

And here inside this full as you can see here we are actually creating a reference to the botanist that



200

00:13:28,230 --> 00:13:30,250

we have inside these rows.



201

00:13:30,270 --> 00:13:32,530

So button button assignment operator.



202

00:13:32,520 --> 00:13:37,660

Here we are testing this object a button object so that your child at Klallam.



203

00:13:37,830 --> 00:13:41,970

And here we are sitting back in uncolored of the spot and to read as you can see here the packet and



204

00:13:41,970 --> 00:13:43,710

color of these buttons is right.



205

00:13:43,710 --> 00:13:44,110

Right.



206

00:13:44,190 --> 00:13:44,700

Right.



207

00:13:44,910 --> 00:13:46,940

So button that text color color that white.



208

00:13:47,100 --> 00:13:50,800

And we're also setting the color of these buttons to white.



209

00:13:51,250 --> 00:13:52,340

And here we are sitting.



210

00:13:52,340 --> 00:13:55,440

That takes colored off this is the answer to color that white.



211

00:13:55,440 --> 00:14:00,000

So let me guess the name as you can see Lyon as you can see the back in uncolored.



212

00:14:00,030 --> 00:14:05,220

Actually the text color of the answer is white and if you are sitting at your request question number



213

00:14:05,220 --> 00:14:11,820

of this is to set the text color color that white right and via Here we be put a statement.



214

00:14:12,150 --> 00:14:15,590

And now let me talk about this case red as you can see here.
