1

00:00:00,480 --> 00:00:03,850

So now let's actually look at this piece of code here.



2

00:00:04,020 --> 00:00:08,710

As you can see I am actually dividing the number of options by two.



3

00:00:09,030 --> 00:00:16,200

So now let me show you the emulator here and now let me show you the of the final version of the application



4

00:00:16,230 --> 00:00:18,080

of our Quiz application.



5

00:00:18,210 --> 00:00:21,020

As you can see here now we have two rows here right.



6

00:00:21,030 --> 00:00:23,390

So now this actually click on these settings here.



7

00:00:23,400 --> 00:00:25,300

Let's go inside the settings activity.



8

00:00:25,710 --> 00:00:31,530

And now let's just click on this number of guesses here as you can see now for example I want to have



9

00:00:31,710 --> 00:00:33,810

sex I guess options right.



10

00:00:33,810 --> 00:00:36,790

I want to have sex just options inside my quiz.



11

00:00:37,050 --> 00:00:41,620

So now let's actually click on it and now it says new changes are applied.



12

00:00:41,640 --> 00:00:45,690

And if I click on dispatch button here at the top as you can see here.



13

00:00:45,750 --> 00:00:48,320

Now we have six guest options here.



14

00:00:48,360 --> 00:00:49,220

Right.



15

00:00:49,380 --> 00:00:58,550

So now as you can see we have free throws we have six guest options and we have free throws.



16

00:00:58,650 --> 00:01:01,260

So in each row we have two buttons.



17

00:01:01,260 --> 00:01:03,110

The first row has two buttons.



18

00:01:03,120 --> 00:01:07,290

The second rule has two buttons and the first row has also two buttons.



19

00:01:07,290 --> 00:01:12,490

So that's why here we are actually dividing this number of just options by two.



20

00:01:12,630 --> 00:01:20,160

So for example if the user wants to have for example only two options then for example two.



21

00:01:20,340 --> 00:01:25,950

Now the number of options here is two right here the value that we get from the share preferences from



22

00:01:25,950 --> 00:01:28,360

these key guesses is going to be two.



23

00:01:28,470 --> 00:01:30,870

So here we are actually dividing two by two.



24

00:01:30,870 --> 00:01:33,570

So two divided by two results in the Value.



25

00:01:33,570 --> 00:01:36,880

Number one right two divided by two is one.



26

00:01:37,020 --> 00:01:42,690

So this means that we are going to actually assign that number one to this number of animals get through.



27

00:01:42,780 --> 00:01:46,180

So the number of animals gets a rose is going to be only one.



28

00:01:46,350 --> 00:01:50,970

And that means that we are going to have only one just throw as you can see here.



29

00:01:51,140 --> 00:01:51,590

Right.



30

00:01:51,630 --> 00:01:54,270

One gets through that has two buttons.



31

00:01:54,300 --> 00:01:56,400

So that's why we actually divided.



32

00:01:56,400 --> 00:01:59,180

Number of options divided by two as he has here.



33

00:01:59,250 --> 00:02:05,280

We actually divide that number of options by two and we assigned the result to this number of animals.



34

00:02:05,290 --> 00:02:06,880

Jethro's.



35

00:02:07,080 --> 00:02:08,740

So hopefully that makes sense.



36

00:02:08,980 --> 00:02:12,370

And now as you can see here we have actually a for loop.



37

00:02:12,540 --> 00:02:18,310

And let's look at this for loop here for linearly out horizontal linear layout.



38

00:02:18,330 --> 00:02:18,890

Right.



39

00:02:18,890 --> 00:02:25,320

So now let me tell you that this Meffert here modified animal guestrooms is going to be executed every



40

00:02:25,320 --> 00:02:28,850

time we actually change the number of guesses here.



41

00:02:29,070 --> 00:02:34,300

Every time we change for example the number of options that we want to have inside our quiz.



42

00:02:34,320 --> 00:02:38,170

So for example we want to have only Fortius options as you can see here.



43

00:02:38,310 --> 00:02:43,180

So in that specific time these are here the Smurfette is going to be executed.



44

00:02:43,200 --> 00:02:47,890

So now as you can see did you see what they did here.



45

00:02:48,100 --> 00:02:50,270

I actually created a break point.



46

00:02:50,300 --> 00:02:56,000

So these are great points and these are actually used when we want to actually debugged the application



47

00:02:56,660 --> 00:02:58,250

in a more advanced way.



48

00:02:58,490 --> 00:03:03,470

But I'll touch on talking more about these breakpoints later but for now if you accidentally create



49

00:03:03,470 --> 00:03:06,770

a break point just a click on it and then it will disappear.



50

00:03:06,770 --> 00:03:07,700

As you can see here.



51

00:03:07,940 --> 00:03:12,180

So now as you can see here we have this method modify animal throws.



52

00:03:12,530 --> 00:03:17,920

And this method is going to be called when everybody use it actually changes the number of U.S. options.



53

00:03:17,960 --> 00:03:22,730

And here as you can see for example when I went over here we have to get options right.



54

00:03:22,730 --> 00:03:26,530

We have actually four I guess options and we have to guess Stroh's as you can see.



55

00:03:26,540 --> 00:03:31,580

So now we want to have sex I guess options and I want to have yes rules.



56

00:03:31,700 --> 00:03:37,120

So I just clicked on the sex here and when I click on dispatch button here as you can see the news is



57

00:03:37,130 --> 00:03:37,950

reset.



58

00:03:38,180 --> 00:03:41,290

And now as you can see we have six options.



59

00:03:41,450 --> 00:03:45,110

So we're able to for example change the number of just options.



60

00:03:45,110 --> 00:03:49,160

First I need to actually delete the previous guest options.



61

00:03:49,160 --> 00:03:54,000

So as again as you can see here now you have six gives options and I want to have for example to get



62

00:03:54,020 --> 00:03:55,770

options right now.



63

00:03:55,790 --> 00:03:59,950

First of all I need to actually delete the previous guest options.



64

00:04:00,020 --> 00:04:06,410

So that's what this for loop here is doing for linear out horizontally nearly out as you can see here.



65

00:04:06,410 --> 00:04:13,040

Now you want to actually to either iterate or the values of this are 8 rows of just spottiness in animalcules.



66

00:04:13,040 --> 00:04:18,680

So this it actually holds those linear layouts that we have inside the Cousteau's horizontal linearly



67

00:04:18,680 --> 00:04:20,970

outs that actually contain buttons.



68

00:04:21,200 --> 00:04:26,780

So horizontal linearly out inside the rows of just buttons in Animal cookies.



69

00:04:27,080 --> 00:04:33,470

And now as you can see here this fall here is going to be executed for each linearly out that we have



70

00:04:33,470 --> 00:04:36,610

inside these eight rows of spottiness in animalcules.



71

00:04:36,620 --> 00:04:42,770

So if you actually scroll to the top here as you can see we actually initialized these rows of just



72

00:04:42,770 --> 00:04:45,350

buttons in animalcules inside the uncreate view.



73

00:04:45,530 --> 00:04:46,190

Right.



74

00:04:46,190 --> 00:04:50,430

So now we are sure that this was like a spottiness is actually initialized.



75

00:04:50,450 --> 00:04:56,600

And when I referred to these rows I guess what as in animal quiz we can actually be sure 100 percent



76

00:04:56,900 --> 00:04:59,200

that this idea is actually initialized.



77

00:04:59,360 --> 00:05:02,550

And then I want to eat right over the values of this grape.



78

00:05:02,570 --> 00:05:09,770

Now I can actually say that horizontal linearly out that set with a visibility view that's gone.



79

00:05:10,040 --> 00:05:17,960

So when I say view that God is going to actually eliminate all those linearly outs that we had in the



80

00:05:17,960 --> 00:05:24,460

previous actually in the previous version in the previous settings right.



81

00:05:24,500 --> 00:05:30,500

So now this is actually updated the number of options now is updated.



82

00:05:30,720 --> 00:05:37,560

But when I actually want to change the number of guest options I need to eliminate all those linear



83

00:05:37,570 --> 00:05:40,890

layouts that had buttons just buttons inside them.



84

00:05:40,890 --> 00:05:46,060

I need to eliminate all of all of those linearly outs and then I can add the new.



85

00:05:46,100 --> 00:05:47,310

I took the options.



86

00:05:47,310 --> 00:05:49,260

Then you asked linearly out.



87

00:05:49,440 --> 00:05:55,430

So first I need to eliminate all those previous layouts so linearly or horizontal linearly out either



88

00:05:55,430 --> 00:05:59,570

right over to the values of these rows of spottiness in any McAleese.



89

00:05:59,730 --> 00:06:03,790

So these are other linearly out of the search visibility view that's gone right.



90

00:06:05,070 --> 00:06:10,890

And then as you can see we have another for loop so this for loop is going to actually put the newest



91

00:06:11,490 --> 00:06:15,530

horizontal linearly out then US guest options into our quiz.



92

00:06:15,570 --> 00:06:17,380

So four in a row.



93

00:06:17,400 --> 00:06:19,240

So as you can see here the row is zero.



94

00:06:19,470 --> 00:06:24,570

And here we created a condition that specifies that how many times this for loop here is going to be



95

00:06:24,570 --> 00:06:25,350

executed.



96

00:06:25,470 --> 00:06:30,800

So until the value of this row is less than the value of this a number of animals guess throws.



97

00:06:30,820 --> 00:06:34,850

So this variable is going to hold the number of throws that we have inside the.



98

00:06:34,860 --> 00:06:35,330

Right.



99

00:06:35,460 --> 00:06:41,130

As you can see we assign a value to this right here but here so low plus plus So here we are saying



100

00:06:41,130 --> 00:06:46,200

that after each execution of this for loop it's going to actually it's going to increment that the value



101

00:06:46,200 --> 00:06:47,920

of this sort of valuable by 1.



102

00:06:48,150 --> 00:06:53,170

So let's actually go inside the curly braces of this for a loop here and let's see what's going on here.



103

00:06:53,340 --> 00:06:56,940

So rows of guess spottiness in animal quiz.



104

00:06:56,970 --> 00:07:03,930

So I am referring to these three rows of buttons in animalcules sup row as you can see here rows of



105

00:07:04,040 --> 00:07:09,270

spot and in animal Sabratha for the first time that this group is going to be executed the value of



106

00:07:09,270 --> 00:07:10,160

this rule is zero.



107

00:07:10,170 --> 00:07:10,760

Right.



108

00:07:10,770 --> 00:07:15,220

So when I say rolls I've just put in as in animalcules Sobero is going actually it's going to go inside



109

00:07:15,240 --> 00:07:21,800

the inside this area and it's going to go inside the first index of this Aure inside index zero of this



110

00:07:21,850 --> 00:07:27,610

array and it's going to call this method and that's a value that is inside of the index 0 of this at



111

00:07:27,610 --> 00:07:32,140

a set visibility view that's visible as you can see here.



112

00:07:32,160 --> 00:07:35,600

Now as you can see this linearly out here is actually visible.



113

00:07:36,940 --> 00:07:40,590

So now hopefully you can understand what that what's going on here.



114

00:07:40,670 --> 00:07:46,720

First we're actually getting the number of guest options that we have inside our activity as you can



115

00:07:46,720 --> 00:07:47,080

see here.



116

00:07:47,080 --> 00:07:51,360

For example two four or six foot now I want to actually for example choose fourth.



117

00:07:51,610 --> 00:07:56,480

And then as you can see here we are actually dividing that value by two.



118

00:07:56,590 --> 00:07:59,550

First I am actually converting that value to an integer value.



119

00:07:59,560 --> 00:08:06,030

And then I am dividing that value by two in order to specify the number of actually gets throws.



120

00:08:06,070 --> 00:08:10,060

So and then we can actually assign that value to this number of animals just throws.



121

00:08:10,090 --> 00:08:18,160

So this variable now holds the number of animals gets ROSS Right and then so four divided by two is



122

00:08:18,190 --> 00:08:20,010

actually two right.



123

00:08:20,100 --> 00:08:24,130

And now this means that the value of this number of animals gastos is two.



124

00:08:24,130 --> 00:08:27,410

So this means that we are going to have to guess rules as you can see here.



125

00:08:27,790 --> 00:08:28,560

Right.



126

00:08:28,630 --> 00:08:33,710

And then first I need to actually eliminate the previous guest options.



127

00:08:33,820 --> 00:08:39,300

So for linearly out horizontal linearly out it's going to iterate over the values of this Aure rows



128

00:08:39,310 --> 00:08:41,700

of good spottiness in Animal cookies.



129

00:08:41,800 --> 00:08:47,380

And then it's going to actually set the visibility of those linear layouts to view that gun.



130

00:08:47,470 --> 00:08:50,240

Right so it's going to actually eliminate all of those.



131

00:08:50,300 --> 00:08:53,230

So just notice that we have viewed that invisible.



132

00:08:53,680 --> 00:08:55,520

And we have view that gun.



133

00:08:55,660 --> 00:09:00,270

When I say view that gun is going I should eliminate all those components inside to use an interface.



134

00:09:00,430 --> 00:09:06,220

And when I say that invisible those components are going to be dead inside that use an interface.



135

00:09:06,220 --> 00:09:08,410

But the user cannot see them.



136

00:09:08,410 --> 00:09:16,030

And when I say view that gun is going to eliminate all those user interfaces all those actually components



137

00:09:16,030 --> 00:09:17,390

inside the user interface.



138

00:09:17,530 --> 00:09:18,120

Right.



139

00:09:18,130 --> 00:09:19,580

So horizontally nearly out.



140

00:09:19,710 --> 00:09:26,600

That said visibility review that's gone and then it's going to actually put the newest linearly out



141

00:09:26,600 --> 00:09:28,880

to the USGS options into the screen.



142

00:09:28,930 --> 00:09:34,870

So for in throw until the value of this throw is less than the number of animals gets close and then



143

00:09:34,870 --> 00:09:39,090

it's going to actually add one value to the value of this row after each execution of this fall.



144

00:09:39,220 --> 00:09:43,700

And then we call this Arev rules of guess spottiness in animalcules Sobero.



145

00:09:43,900 --> 00:09:45,890

That a visibility view that visible.



146

00:09:46,120 --> 00:09:47,240

Right.



147

00:09:47,260 --> 00:09:49,630

So hopefully that makes sense.



148

00:09:49,630 --> 00:09:56,080

And now as you can see this is our Actually method for modifying the guests rose.



149

00:09:56,130 --> 00:10:00,370

We need to actually call other methods for example as you can see if I go inside the settings activity



150

00:10:00,630 --> 00:10:04,380

we need to actually provide a logic for this option for this item.



151

00:10:04,420 --> 00:10:07,500

Animals the type of the animals that we want to have inside the crease.



152

00:10:07,690 --> 00:10:12,590

So now let's actually create a method for that here inside this class.
