How To Create Your First Android Application with Java

Create Your First Android Application with Java in Android Studio Integrated Development Environment (I.D.E).The App that I will be making in this video is the simplest one and perfect for beginners. Watch this video till the end to be able to understand it completely. You need some basic knowledge about Java to make an Android App.

Hey Guys!
Its Teja here!
In this video, I will be teaching you how to create your first Android App in Java.
In this video, I will be teaching you to make a simple clicker application for Android. This App is simple and it just shows us on what Button we clicked. Its perfect for beginners to get started with this simple application.

DESIGN

Coding
Then we need to link all these four elements to our Main Activity class. The MainActivity class is the first thing that is going to be executed when our Android App is executed.
In the MainActivity class, we need to import the widget java package to be able to use the three buttons and one TextView that we used in the xml file(our Application Layout)

To import the button class from the Widget library, use the code :

To import the TextView class from the widget Library, use the code :

After importing these, you have to declare these in your Main Activity class. You can do that by simply saying :
Button buttonA;
Button buttonB;
Button buttonC;
TextView txtView;

The next thing is to set OnClick Listener to the three buttons. You can do so by typing :
buttonA.setOnClickListener(this);
buttonB.setOnClickListener(this);
buttonC.setOnClickListener(this);

Make sure that you implement OnClickListener to your MainActivity class.

Now we can programatically know whenever the user clicks on any of the three buttons since we are listening to the clicks using OnClickListener.
Next thing is, perform some activity whenever the user clicks on a Button in our Applciation.

So, start a OnCreate method. This OnCreate method is going to be executed whenever the user clicks on any of the three buttons.
And then, we are going to change the text of the textView basing on what button the user clicked using the setText() method. You can simply say :

Thats it!

Nice work bruh! I was trying to learn java and i just learn "if else"and many subjects... Its really helpful to see how to use it...

[nandakumar]

Very good working example! The buttons overlapped on run time and I need to configure target device emulator to run. For button overlapping constraints issue in Android Studio on Design tab select controls one by one and on top find 'Infer Constraints' icon and click. It will be resolved. Thanks!
