1

00:00:00,200 --> 00:00:06,680

Hire everyone in this theater you are going to go ahead and create our 14th Android application.



2

00:00:06,870 --> 00:00:07,860

So just click on this.



3

00:00:07,860 --> 00:00:10,000

Start in your Android studio project.



4

00:00:10,110 --> 00:00:17,340

And here we need to actually specify our name for our application app 14 and you can actually specify



5

00:00:17,340 --> 00:00:21,230

the company domain package name and project location.



6

00:00:21,270 --> 00:00:26,710

Click next and here choose API 16 Android 4.1 jellybean.



7

00:00:26,990 --> 00:00:30,310

OK click clicking next blank activity.



8

00:00:30,660 --> 00:00:33,490

Next And here don't change anything.



9

00:00:33,510 --> 00:00:35,000

And then we can finish here.



10

00:00:35,010 --> 00:00:37,390

Delete this hello or text view.



11

00:00:37,800 --> 00:00:43,500

And then double click on the rest folder and lay out and then double click on the activity on the line



12

00:00:43,500 --> 00:00:49,110

main and then select this fluting action button and then press delete key on your keyboard.



13

00:00:49,110 --> 00:00:50,020

OK.



14

00:00:50,310 --> 00:00:54,280

So let's go back inside this content on the line of the example.



15

00:00:54,420 --> 00:00:57,530

And here we can actually design our user interface.



16

00:00:57,540 --> 00:00:57,970

Ok.



17

00:00:58,020 --> 00:00:58,870

Ok everyone.



18

00:00:58,980 --> 00:01:04,200

Now let's actually track our linear layout vertical into this relatively alloca.



19

00:01:04,200 --> 00:01:08,840

So let's just drag it at the center of the are relatively OK.



20

00:01:08,940 --> 00:01:14,180

At the center of the screen and as you can see here these are linearly at vertical.



21

00:01:14,340 --> 00:01:20,590

So now it's actually dreich are linearly out horizontal into this linear layout vertical OK.



22

00:01:20,940 --> 00:01:23,720

So these are linearly out horizontal.



23

00:01:23,880 --> 00:01:31,080

And now let's actually track two large takes views into this linearly or horizontal that is inside of



24

00:01:31,080 --> 00:01:32,860

this linear left vertical.



25

00:01:33,110 --> 00:01:33,600

OK.



26

00:01:33,690 --> 00:01:36,070

So double click and these are large text view.



27

00:01:36,450 --> 00:01:39,100

And for the text just type in here.



28

00:01:39,210 --> 00:01:44,680

Total value of the array.



29

00:01:46,560 --> 00:01:47,210

OK.



30

00:01:47,460 --> 00:01:50,090

And as you can see here this is our value here.



31

00:01:50,400 --> 00:01:56,460

And now let's actually track and others takes you into this linear layout horizontal select this large



32

00:01:57,150 --> 00:02:04,860

text and then I put it inside these linearly and horizontal and double click on it and delete the text



33

00:02:04,860 --> 00:02:06,680

of this text view.



34

00:02:07,260 --> 00:02:11,030

And for the idea Id just type in here takes the total.



35

00:02:11,230 --> 00:02:12,140

OK.



36

00:02:12,810 --> 00:02:19,640

And as you can see here these are our two text views that are actually inside of these linearly and



37

00:02:19,650 --> 00:02:20,330

horizontal.



38

00:02:20,330 --> 00:02:28,020

OK so now let's assume that the weight of this linearly and horizontal is 100.



39

00:02:28,090 --> 00:02:35,750

OK so now I want to actually allocate 80 percent of the width of these linearly at horizontal to this



40

00:02:35,870 --> 00:02:40,100

it takes you here OK total by the total value of the array.



41

00:02:40,110 --> 00:02:47,250

So here for the width of this takes you just assign the value 0 and for the weight of this text view



42

00:02:47,670 --> 00:02:50,690

for the length of 8 assigned the value 80.



43

00:02:51,030 --> 00:02:53,030

So let me explain again.



44

00:02:53,040 --> 00:02:58,500

I assumed that the weight of these are linearly held horizontally is 100.



45

00:02:58,500 --> 00:02:58,780

OK.



46

00:02:58,800 --> 00:03:06,570

And I want to actually allocate 80 percent of the weight of this linearly or horizontal to the weight



47

00:03:06,660 --> 00:03:10,200

of this a total value of the Great Lakes view OK.



48

00:03:10,260 --> 00:03:15,380

So I actually assigned the value 0 to the of which of these takes you.



49

00:03:15,480 --> 00:03:19,460

And then I assign the value 80 to the left rate of the sticks.



50

00:03:19,470 --> 00:03:20,120

OK.



51

00:03:20,490 --> 00:03:23,930

So here now we have 20 percent left.



52

00:03:23,970 --> 00:03:24,390

OK.



53

00:03:24,420 --> 00:03:30,440

20 percent of the lay out of the way of these are linearly or isn't what is left.



54

00:03:30,600 --> 00:03:37,200

OK so now let's actually get the value 0 to the lay out which of these takes the total takes view.



55

00:03:37,390 --> 00:03:38,220

OK.



56

00:03:38,810 --> 00:03:45,270

And assign the value 20 to deliberate rate of this takes you.



57

00:03:45,460 --> 00:03:52,570

So as you can see here now this takes you is actually taking 20 percent of the vote of this linearly



58

00:03:52,620 --> 00:03:54,040

and horizontal Okay.



59

00:03:54,630 --> 00:04:02,040

So this is our linearly or horizontal and we assumed that the weight of these artists is 100.



60

00:04:02,140 --> 00:04:02,800

OK.



61

00:04:03,010 --> 00:04:04,510

One hundred percent.



62

00:04:04,800 --> 00:04:11,100

And we gave 80 percent of the base of this linearly or horizontal to this text view here total value



63

00:04:11,100 --> 00:04:16,750

of the array and I assign the value 0 to the level to which of the state's view.



64

00:04:16,860 --> 00:04:21,020

And then I assign the value 80 to the weight of the sticks.



65

00:04:21,450 --> 00:04:25,700

And here I actually assigned the value 0 to the left.



66

00:04:25,710 --> 00:04:31,770

Which of these takes you and I assign the value 20 to the left rate of this takes you OK.



67

00:04:31,830 --> 00:04:33,850

So hopefully that makes sense.



68

00:04:34,080 --> 00:04:39,370

And let's actually track another linearly or horizontal into this linearly alphabetical.



69

00:04:39,490 --> 00:04:40,530

Okay.



70

00:04:40,720 --> 00:04:48,310

So let's actually select this linearly and horizontal and then put it inside this linearly and vertical



71

00:04:48,940 --> 00:04:49,530

OK.



72

00:04:49,620 --> 00:04:54,480

And let's actually do a large text view into this linearly and horizontal OK.



73

00:04:54,690 --> 00:05:01,100

You can either put it here or get inside this layout or you can actually inside this component restriction.



74

00:05:01,210 --> 00:05:05,340

Again just put it here inside this linearly out horizontal OK.



75

00:05:06,030 --> 00:05:08,760

And now that's actually double click.



76

00:05:08,790 --> 00:05:11,750

And these are text view for the text.



77

00:05:11,880 --> 00:05:13,920

Just delete the text of this text view.



78

00:05:14,220 --> 00:05:18,570

And for the ID just type in here DXi triangulations.



79

00:05:18,680 --> 00:05:25,840

OK I want are these tactics the calculation takes you to be at the center of this linearly or horizontal.



80

00:05:25,980 --> 00:05:31,950

So I just need to clear this linearly at horizontal and then I can just find the gravity attribute here.



81

00:05:31,950 --> 00:05:32,720

As you can see.



82

00:05:32,910 --> 00:05:39,010

So I just need to check this check box here that says Center underline horizontal OK.



83

00:05:39,240 --> 00:05:44,530

So if I select this takes you now as you can see this text view is at the center of this linearly out



84

00:05:44,620 --> 00:05:45,790

horizontal OK.



85

00:05:45,930 --> 00:05:49,820

It is actually positioned at the center of this linearly and horizontal.



86

00:05:49,910 --> 00:05:55,710

So now let's actually go back and say this main activity that I will find here again delete these lines



87

00:05:55,710 --> 00:05:59,230

of code that are actually related to the options menu here.



88

00:05:59,580 --> 00:06:03,760

This block of code that is actually related to the to the floating action button.



89

00:06:04,050 --> 00:06:07,310

And now we can actually put our own code here.



90

00:06:07,320 --> 00:06:07,890

OK.



91

00:06:07,920 --> 00:06:10,440

Now inside these are uncreate Smurfette.



92

00:06:10,530 --> 00:06:12,990

Actually create two text view objects.



93

00:06:12,990 --> 00:06:18,720

So I just need to refer to the name of the text your class DX the total



94

00:06:21,590 --> 00:06:27,900

OK assignment operator and then I need to actually cast this object to take textbook object find view



95

00:06:27,940 --> 00:06:38,760

by id artist or E.T. that takes the total OK and this actually create another text object to the calculations



96

00:06:40,640 --> 00:06:41,280

OK.



97

00:06:41,290 --> 00:06:42,500

Assignment operator.



98

00:06:42,730 --> 00:06:51,120

And then here I need to cast this object to test your object find view by ID or thought Id dot the calculation.



99

00:06:51,140 --> 00:06:52,140

Okay.



100

00:06:53,050 --> 00:07:02,950

And here let's actually create a string object all text and I don't want to actually insensate this



101

00:07:02,950 --> 00:07:03,810

object here.



102

00:07:03,910 --> 00:07:07,690

So now this actually creates an array of integer numbers.



103

00:07:07,780 --> 00:07:11,660

So I just need to refer to the name of the integer primitive data type.



104

00:07:11,800 --> 00:07:12,390

OK.



105

00:07:12,550 --> 00:07:16,960

And then I want to actually specify that I am going to actually and then I need to actually specify



106

00:07:16,960 --> 00:07:24,130

that I am going to actually create an integer Ali by putting a pair of brackets after my type and then



107

00:07:24,370 --> 00:07:26,710

I need to actually give a name to this array.



108

00:07:26,710 --> 00:07:35,170

So I just need to type in here integer array and then I put an assignment operator here and now I want



109

00:07:35,170 --> 00:07:37,300

to actually instantiate this array.



110

00:07:37,330 --> 00:07:45,070

So I just put in a pair of curly braces here and then I will actually specify my values that I want



111

00:07:45,070 --> 00:07:46,490

to actually assign to this address.



112

00:07:46,510 --> 00:07:47,110

OK.



113

00:07:47,440 --> 00:08:03,440

So here for example Number 2 54 54 76 23 and 4 7 8 6 4 and 65.



114

00:08:03,720 --> 00:08:04,430

OK.



115

00:08:05,080 --> 00:08:11,330

And now I can actually put a semicolon at the end of my statement here.



116

00:08:11,800 --> 00:08:22,180

And let's actually create an integer variable in total value assigning number 0 to this variable and



117

00:08:22,240 --> 00:08:24,120

essentially create a for loop here.



118

00:08:24,130 --> 00:08:29,110

OK for each index.



119

00:08:29,750 --> 00:08:30,180

OK.



120

00:08:30,250 --> 00:08:33,110

And then I assign number 0 to this variable.



121

00:08:33,250 --> 00:08:38,950

And then here I need to actually specify a condition in which this loop is going to be executed until



122

00:08:38,950 --> 00:08:42,360

index is less than integer array.



123

00:08:43,000 --> 00:08:45,270

OK that length.



124

00:08:45,670 --> 00:08:48,450

And now I need to actually specify that.



125

00:08:48,580 --> 00:08:55,050

And here I need to actually specify that after each execution of this for a loop the value of this index



126

00:08:55,060 --> 00:08:59,230

variable is going to be incremented by 1 index plus plus.



127

00:08:59,560 --> 00:09:03,910

And then I need to actually open and closed this for loop by using these curly braces.



128

00:09:03,910 --> 00:09:10,270

And here I want to actually add the values of the integer array together and then I want to assign that



129

00:09:10,270 --> 00:09:11,600

value to the total value.
