1

00:00:00,180 --> 00:00:05,600

Hire everyone in this theater you are always going to go ahead and create another Android application.



2

00:00:05,610 --> 00:00:06,540

So just click on this.



3

00:00:06,540 --> 00:00:14,340

Start in your Android studio project and for the application name just type in your app 46 and here



4

00:00:14,550 --> 00:00:24,140

for the minimum SDK choose API 16 Android 4.1 Jelly Bean and then click on next and here choose MT activity.



5

00:00:24,320 --> 00:00:24,770

OK.



6

00:00:24,840 --> 00:00:25,680

Next.



7

00:00:26,010 --> 00:00:28,170

And then here click on finish.



8

00:00:28,710 --> 00:00:31,970

So now as you can see our application is created.



9

00:00:32,160 --> 00:00:34,730

Let's actually double click on this folder here.



10

00:00:34,860 --> 00:00:40,060

Double click on this layout folder and then double click on this activity underline that example.



11

00:00:40,350 --> 00:00:46,940

So here as you can see this is our activity underline made that example and here we have some errors.



12

00:00:46,980 --> 00:00:54,120

So in order to fix the error there is a bug in Android studio and my actually my project couldn't identify



13

00:00:54,120 --> 00:00:55,690

the proper Feme.



14

00:00:55,800 --> 00:01:02,160

So in order to solve that error you need to actually click on this field here at the top and then here



15

00:01:02,160 --> 00:01:06,370

you can actually click on material that light or material dark.



16

00:01:06,510 --> 00:01:14,160

So I prefer this material light and here choose material that light that dot dot action.



17

00:01:14,170 --> 00:01:16,820

But OK I prefer I prefer this film.



18

00:01:16,950 --> 00:01:20,930

You can actually choose other films but I think this film is better.



19

00:01:20,970 --> 00:01:22,280

And then click on OK.



20

00:01:22,560 --> 00:01:27,570

So now here is our application and we have actually a dart action bar here.



21

00:01:27,600 --> 00:01:30,510

So now it's actually the selectees hello world takes you.



22

00:01:30,530 --> 00:01:33,350

And then press on delete key on your keyboard.



23

00:01:33,660 --> 00:01:38,560

And here now I want to actually use tab host in my application.



24

00:01:38,590 --> 00:01:43,550

So inside the containers folder we have this tab host here.



25

00:01:43,560 --> 00:01:44,140

OK.



26

00:01:44,220 --> 00:01:47,410

So just select it and then put it inside.



27

00:01:47,410 --> 00:01:50,120

These are truly inside these relatively out.



28

00:01:50,130 --> 00:01:52,860

So just put it at the center of this relatively out.



29

00:01:52,860 --> 00:01:53,420

OK.



30

00:01:53,640 --> 00:01:55,700

So here is our tab host.



31

00:01:55,860 --> 00:02:02,710

And as you can see let's actually go back go to our text tab here and here is the code.



32

00:02:02,730 --> 00:02:08,890

The lines of code that are related to the user interface and here as you can see we have this tab host.



33

00:02:08,910 --> 00:02:09,560

OK.



34

00:02:09,870 --> 00:02:16,710

And if you have a linear layout vertical inside that table top host we have this tab widget as you can



35

00:02:16,710 --> 00:02:17,370

see.



36

00:02:17,550 --> 00:02:21,540

And we have this frame layout inside that tab widget as you can see here.



37

00:02:21,630 --> 00:02:25,700

And we have this frame layout inside this linearly out here.



38

00:02:26,010 --> 00:02:31,520

And we have also some linearly outs inside these linearly out vertical.



39

00:02:31,530 --> 00:02:34,640

So let's actually delete this linearly else here.



40

00:02:34,680 --> 00:02:38,220

I'll talk more about this later for now just delete them.



41

00:02:38,280 --> 00:02:45,990

So now I have only a tab host and inside that tab host we have this vertical linearly out and inside



42

00:02:45,990 --> 00:02:50,660

that vertical linearly out we have this tab widget and frameless out.



43

00:02:50,720 --> 00:02:54,660

OK so now let's actually to go back to our design.



44

00:02:54,690 --> 00:02:57,000

So here is our user interface.



45

00:02:57,000 --> 00:03:01,700

And as you can see here we have these user interface components in our screen.



46

00:03:01,800 --> 00:03:07,300

So let's actually to select this tab host here and now I want to actually give an idea to the top post.



47

00:03:07,320 --> 00:03:13,530

So as you can see here this is the id attribute of this tab host and the default is tab host.



48

00:03:13,590 --> 00:03:14,830

And I think that's OK.



49

00:03:14,910 --> 00:03:15,480

OK.



50

00:03:15,750 --> 00:03:19,640

So let's actually go back to our main activity the java file here.



51

00:03:19,680 --> 00:03:22,310

So here we're going to actually put in some lines of code here.



52

00:03:22,410 --> 00:03:26,610

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



53

00:03:26,610 --> 00:03:27,210

here.



54

00:03:27,210 --> 00:03:34,590

So inside our main activity class first of all we need to actually extend from the activity group class.



55

00:03:34,590 --> 00:03:37,930

Ok not an accomplished activity activity group.



56

00:03:37,950 --> 00:03:38,850

So let's actually did it.



57

00:03:38,860 --> 00:03:40,400

These are computer activity.



58

00:03:40,680 --> 00:03:44,140

And change it to Activity Group.



59

00:03:44,880 --> 00:03:45,180

OK.



60

00:03:45,180 --> 00:03:47,240

And that person entered here on your keyboard.



61

00:03:47,310 --> 00:03:50,210

So as you can see here it is deprecated.



62

00:03:50,400 --> 00:03:56,550

And so as a developer you need to know how to actually work with this activity group.



63

00:03:56,700 --> 00:03:58,890

But for now we use this activity.



64

00:03:59,010 --> 00:04:06,780

And then later in this tutorial I'll talk more about using other ways in order to use taphouse in our



65

00:04:06,780 --> 00:04:07,800

application.



66

00:04:07,830 --> 00:04:10,270

But for now we want to use activity group.



67

00:04:10,380 --> 00:04:15,540

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



68

00:04:15,540 --> 00:04:16,320

on here.



69

00:04:16,650 --> 00:04:20,620

So as you can see here these are the two lines of code that I actually paste that here.



70

00:04:20,640 --> 00:04:23,990

First of all I created an object of type Paphos.



71

00:04:24,030 --> 00:04:24,730

OK.



72

00:04:24,900 --> 00:04:26,210

Assignment operator.



73

00:04:26,250 --> 00:04:33,630

So I actually cast this object to a tab host object find view by ID or that ID that have host.



74

00:04:33,630 --> 00:04:38,860

So here I am actually referring to this tab host that I have inside are exemplified.



75

00:04:38,910 --> 00:04:39,420

OK.



76

00:04:39,550 --> 00:04:41,540

Inside these are relatively out.



77

00:04:41,880 --> 00:04:44,520

So here I have this taphouse object.



78

00:04:44,670 --> 00:04:49,530

And here in line 16 I am referring to this object tab host that's set up.



79

00:04:49,560 --> 00:04:53,380

So here I want to set up the tab host for my application.



80

00:04:53,610 --> 00:04:59,030

And here I call this if it gets activity local get local activity manager.



81

00:04:59,250 --> 00:05:02,240

So this before comes from this activity group class.



82

00:05:02,270 --> 00:05:05,520

So if you to the poll to come and keep on my keyboard.



83

00:05:05,540 --> 00:05:09,800

So if you are using a Windows machine you need to hold the controls on your keyboard.



84

00:05:09,910 --> 00:05:14,630

Here I just need to hold the command key and then present this method here.



85

00:05:14,630 --> 00:05:17,770

And as you can see here I have this activity group that over here.



86

00:05:17,990 --> 00:05:20,680

And as you can see this lever is inside this file.



87

00:05:20,720 --> 00:05:22,450

Get local activity manager.



88

00:05:22,760 --> 00:05:30,080

So here I need to actually get this Mefford get local activity manager in order to actually manage my



89

00:05:30,080 --> 00:05:30,770

activity.



90

00:05:30,860 --> 00:05:31,470

OK.



91

00:05:31,640 --> 00:05:36,290

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



92

00:05:36,290 --> 00:05:37,150

going on here.



93

00:05:37,280 --> 00:05:43,070

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



94

00:05:43,370 --> 00:05:46,480

So here as you can see in line to anyone.



95

00:05:46,580 --> 00:05:49,330

I created an object of type papped spec.



96

00:05:49,340 --> 00:05:52,290

OK tab host tab spek.



97

00:05:52,520 --> 00:05:57,600

And the name of this object is spech assignment operator tab host.



98

00:05:57,620 --> 00:06:01,940

So here you referred to this tab host that Neal tab spit.



99

00:06:02,000 --> 00:06:05,990

OK so I want to actually create some tabs in my application or.



100

00:06:06,140 --> 00:06:10,250

Like a tab application so tab host that new tab spec.



101

00:06:10,280 --> 00:06:14,620

So here as you can see if you have this argument and this argument is attack.



102

00:06:14,660 --> 00:06:15,110

OK.



103

00:06:15,200 --> 00:06:20,170

And instead of double quotes as you can see I specified the tag of this type one.



104

00:06:20,390 --> 00:06:21,000

OK.



105

00:06:21,440 --> 00:06:29,480

And here I in line 22 I am specifying the indicator of the spec spec that set indicator type 1.



106

00:06:29,750 --> 00:06:34,040

So now I'm going to run our project and then I'm going to show you what is going to be this indicator



107

00:06:34,250 --> 00:06:41,400

and 11:23 I have this intense object so intense intent one new intent.



108

00:06:41,540 --> 00:06:44,840

So here I want to actually move from this activity to this activity.



109

00:06:44,840 --> 00:06:50,420

OK first that activity so main activity that this this is going to be our first activity and here I



110

00:06:50,420 --> 00:06:52,410

want to move to this activity.



111

00:06:52,490 --> 00:06:54,380

First that activity that class.



112

00:06:54,440 --> 00:06:59,050

So as you can see here we don't have this activity in our project so we need to create this activity



113

00:06:59,310 --> 00:07:06,210

and inline 24 I actually referred to this spec object that said content intent.



114

00:07:06,220 --> 00:07:06,870

1.



115

00:07:07,280 --> 00:07:07,800

OK.



116

00:07:07,910 --> 00:07:15,350

So I want to actually put this into one inside this spec OK for the content.



117

00:07:15,350 --> 00:07:23,810

And here I actually add this tab to this top host tab host that add tab spec as you can see here.



118

00:07:23,810 --> 00:07:28,120

So now let's actually create this first that activity in our project.



119

00:07:28,130 --> 00:07:35,390

So here in our project structure as you can see here I just click on this package here and right click



120

00:07:35,390 --> 00:07:35,910

on it.



121

00:07:36,190 --> 00:07:36,890

OK.



122

00:07:37,310 --> 00:07:38,870

And then here new.



123

00:07:39,180 --> 00:07:39,490

OK.



124

00:07:39,500 --> 00:07:45,770

And then click on it and as you can see we have this activity here and here I can just select is empty



125

00:07:45,770 --> 00:07:46,360

activity.



126

00:07:46,370 --> 00:07:47,270

OK.



127

00:07:47,870 --> 00:07:51,880

And for the name of our activity I am going to use this name here.



128

00:07:51,880 --> 00:08:01,160

First that activity as you can see here first tap activity and as you can see here it's going to actually



129

00:08:01,250 --> 00:08:09,320

automatically create another layout with this name activity underlined first underline tap and the package



130

00:08:09,320 --> 00:08:10,630

is going to be this package.



131

00:08:10,640 --> 00:08:11,230

OK.



132

00:08:11,630 --> 00:08:17,450

So now it says interactivity so I don't want this activity to be the lantern activity.



133

00:08:17,480 --> 00:08:20,490

I want the main activity to be that interactive with you OK.



134

00:08:20,540 --> 00:08:24,610

So don't check this checkbox here and then click on finish.



135

00:08:25,220 --> 00:08:29,380

So here as you can see we have this first that activity in our project.



136

00:08:29,480 --> 00:08:36,020

And as you can see here inside this manifest file we have this activity here inside this application



137

00:08:36,020 --> 00:08:36,500

tag.



138

00:08:36,620 --> 00:08:37,080

OK.



139

00:08:37,190 --> 00:08:39,830

And the name that first the that first that activity.



140

00:08:39,840 --> 00:08:40,680

OK.



141

00:08:41,210 --> 00:08:47,590

So as you can see here at the top of this manifest file if you have these ASML namespace.



142

00:08:47,830 --> 00:08:53,810

And here as you can see it specified the default package package and the name of this package is this



143

00:08:53,810 --> 00:08:54,560

package.



144

00:08:54,560 --> 00:08:59,200

So here it just put this dot here and then referred to this class.



145

00:08:59,210 --> 00:09:06,230

Inside this package OK if you would have this class in another package we would need to actually specify



146

00:09:06,500 --> 00:09:10,210

the entire name of the package that this class is inside.



147

00:09:10,400 --> 00:09:10,840

OK.



148

00:09:10,910 --> 00:09:17,480

But because this class is inside this package which we were just typing that first that activity as



149

00:09:17,480 --> 00:09:23,210

you can see here this first activity is inside this package that is that that its name is the same as



150

00:09:23,400 --> 00:09:24,690

that that this name here.



151

00:09:24,740 --> 00:09:25,160

OK.



152

00:09:25,190 --> 00:09:27,500

So hopefully that makes sense.



153

00:09:27,500 --> 00:09:28,910

And inside this may actually be the class.



154

00:09:28,910 --> 00:09:30,870

Now as you can see the error is gone.



155

00:09:30,980 --> 00:09:36,090

So now let's actually open this activity underlined first underline tappet example.



156

00:09:36,500 --> 00:09:38,850

And here as you can see this is our activity.



157

00:09:39,260 --> 00:09:45,800

And here now I'm going to actually drag a linearly out vertical So as you can see here inside this activity



158

00:09:45,800 --> 00:09:51,560

I have this linearly arithmetical here and here and when I put it at the center of this relatively out



159

00:09:51,560 --> 00:09:58,060

here but as you can see here I don't like the theme of this activity of this exemplify.



160

00:09:58,250 --> 00:10:05,000

So I just need to click on this app from here and then here I can just select this material light.



161

00:10:05,200 --> 00:10:05,860

OK.



162

00:10:06,120 --> 00:10:12,480

And here I can't just choose this material that light the dark action and then click on OK.



163

00:10:12,900 --> 00:10:22,230

OK so here this is our activity and we changed the theme of this XML file and now I want to actually



164

00:10:22,230 --> 00:10:27,380

drag our text view a large takes you into this XML file.



165

00:10:27,390 --> 00:10:32,310

So I just need to put it at the center of this linearly Attaway article that I need.



166

00:10:32,940 --> 00:10:42,790

And for the text just type in here this is first tap OK and in person enter key on your keyboard.



167

00:10:43,150 --> 00:10:46,670

So now let's actually go back to our main activity the Java file here.



168

00:10:46,750 --> 00:10:50,770

So first of all let's actually run our project and see what happens.



169

00:10:50,770 --> 00:10:55,020

So as you can see here now our application is running on this emulator.



170

00:10:55,060 --> 00:10:56,850

And here is our tab 1.



171

00:10:56,920 --> 00:11:02,170

So here as you can see be assigned this value for this indicator Tab 1.



172

00:11:02,170 --> 00:11:04,090

And here this is our first tab.



173

00:11:04,090 --> 00:11:04,620

OK.



174

00:11:04,630 --> 00:11:08,170

So this is the value that we actually put inside this activity.



175

00:11:08,170 --> 00:11:10,960

Underline first underline tab that SML.



176

00:11:10,980 --> 00:11:14,430

OK but here as you can see we have this action bar here.



177

00:11:14,440 --> 00:11:14,870

OK.



178

00:11:14,980 --> 00:11:17,440

But I don't like this to be here.



179

00:11:17,470 --> 00:11:20,920

So let's actually go back to our and manifested XML file here.



180

00:11:21,040 --> 00:11:28,430

So here we have this activity that main activity here and here I have to specify a field for this activity.



181

00:11:28,690 --> 00:11:35,390

So here I can just typing Feme and I can just type in no action bar.



182

00:11:35,680 --> 00:11:40,440

So as you can see here it says find that Afkham pads that light that no action.



183

00:11:40,600 --> 00:11:45,030

So just select this and put press Enter key on your keyboard.



184

00:11:45,070 --> 00:11:48,180

So now let's actually go on our project and see what happens.



185

00:11:48,250 --> 00:11:54,130

So here as you can see our application is running on the simulator and we can see this tab one here.



186

00:11:54,130 --> 00:12:01,240

And this is our text inside these tab one here or key activity underlined first that underline tab that



187

00:12:01,260 --> 00:12:01,700

SML.



188

00:12:01,720 --> 00:12:07,480

OK so now let's actually go back to our main activity that our fight here because I want to add some



189

00:12:07,480 --> 00:12:09,770

more caps to my application.



190

00:12:09,940 --> 00:12:11,990

So this is our first stop OK.



191

00:12:12,010 --> 00:12:14,760

So here I want to create the second tab.



192

00:12:14,920 --> 00:12:19,600

So now I'm going to actually paste in some more lines of code here and then I'm going to explain to



193

00:12:19,600 --> 00:12:21,120

you what's going on here.



194

00:12:21,520 --> 00:12:26,950

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



195

00:12:26,950 --> 00:12:32,760

Again I referred to the name of this space object that I actually created in line 21.



196

00:12:32,860 --> 00:12:40,330

As you can see here top post the top spec and here I have this spec top post that new top spec one.



197

00:12:40,510 --> 00:12:42,580

OK so this is the tag for this top.



198

00:12:42,580 --> 00:12:43,280

OK.



199

00:12:43,630 --> 00:12:52,030

And here I actually again referred to this spec object assignment operator tab host that new tab spek



200

00:12:52,180 --> 00:12:52,860

to.



201

00:12:53,200 --> 00:12:53,470

OK.



202

00:12:53,470 --> 00:12:59,750

As you can see here we have this value too as the tag of these are Meffert new top spec.



203

00:12:59,980 --> 00:13:05,380

And here as you can see in line for it to again I referred to the name of this space object that set



204

00:13:05,420 --> 00:13:07,210

indicator tap to.



205

00:13:07,420 --> 00:13:08,120

OK.



206

00:13:08,500 --> 00:13:09,920

And in line for free.



207

00:13:09,940 --> 00:13:16,420

I actually created another intense object and the name of this intense object is intense to assignment



208

00:13:16,450 --> 00:13:18,200

operator new intent.



209

00:13:18,220 --> 00:13:24,040

So this is going to be the activity the first activity that you want to actually transfer transfer from



210

00:13:24,470 --> 00:13:26,020

so main activity that this.



211

00:13:26,260 --> 00:13:31,470

And here it is going to be the second activity that you want to actually transfer to.



212

00:13:31,570 --> 00:13:32,100

OK.



213

00:13:32,320 --> 00:13:36,250

So I want to move from this activity main activity to the second activity.



214

00:13:36,250 --> 00:13:37,780

So as you can see here we have an error.



215

00:13:37,810 --> 00:13:44,620

So we need to actually create this second type activity here in our project and in line 34.



216

00:13:44,650 --> 00:13:50,440

I again referred to the name of this spec object that said content intent to.



217

00:13:50,650 --> 00:13:51,480

OK.



218

00:13:51,820 --> 00:13:53,400

And again inline 35.



219

00:13:53,440 --> 00:13:58,290

I added this tab to this tab host tab host that tab speech.



220

00:13:58,720 --> 00:13:59,550

OK.



221

00:13:59,740 --> 00:14:01,060

So hopefully that makes sense.



222

00:14:01,060 --> 00:14:06,310

And now let's actually create this second tab activity in our project.



223

00:14:06,310 --> 00:14:16,090

So just click on this package here conduct example here and then click on File new here click on activity



224

00:14:16,570 --> 00:14:21,670

and then choose empty activity and the for the name of your activity name.



225

00:14:21,670 --> 00:14:22,710

Just type in here.



226

00:14:22,720 --> 00:14:24,330

Second tap activity.



227

00:14:24,460 --> 00:14:25,310

OK.



228

00:14:25,810 --> 00:14:32,320

And here as you can see we have our lay out name activity underlined second underline tab and here it



229

00:14:32,320 --> 00:14:33,770

says generate outfight.



230

00:14:33,780 --> 00:14:36,820

OK it's really important that you actually check this checkbox.



231

00:14:36,880 --> 00:14:40,610

Otherwise it's not going to generate a out file for us.



232

00:14:40,630 --> 00:14:47,150

So now click on finish and as you can see here we have this second type activity and we have also the



233

00:14:47,150 --> 00:14:54,080

Smurfette set content view are that lay out that activity underline say can't underline tap and in say



234

00:14:54,080 --> 00:14:55,280

does mean activity class.



235

00:14:55,280 --> 00:14:57,620

Now as you can see the error is gone.



236

00:14:57,890 --> 00:15:01,650

So now let's actually open our Android manifest.



237

00:15:01,660 --> 00:15:06,400

Here again as you can see we have this line of code automatically here.



238

00:15:06,410 --> 00:15:11,930

This line of code is actually automatically generated for us by the ID activity Android name.



239

00:15:12,040 --> 00:15:13,250

That's second type activity.



240

00:15:13,250 --> 00:15:13,710

OK.
