Android Application that implements Multi threading

To develop a Android Application that implements Multi threading.

Procedure:

Creating a New project:

• Open Android Studio and then click on File -> New -> New project.

• Then type the Application name as “ex.no.7″ and click Next.

• Then select the Minimum SDK as shown below and click Next.

• It will take some time to build and load the project.
• After completion it will look as given below.

Designing layout for the Android Application:

• Click on app -> res -> layout -> activity_main.xml

• Then delete the code which is there and type the code as given below.

Code for Activity_main.xml:

• Now click on Design and your application will look as given below.

• So now the designing part is completed.

Java Coding for the Android Application:

• Click on app -> java -> com.example.exno7 -> MainActivity.

• Then delete the code which is there and type the code as given below.

Code for MainActivity.java:

package com.example.exno7; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.Button; import android.widget.ImageView; public class MainActivity extends AppCompatActivity < ImageView img; Button bt1,bt2; @Override protected void onCreate(Bundle savedInstanceState) < super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); bt1 = (Button)findViewById(R.id.button); bt2= (Button) findViewById(R.id.button2); img = (ImageView)findViewById(R.id.imageView); bt1.setOnClickListener(new View.OnClickListener() < @Override public void onClick(View v) < new Thread(new Runnable() < @Override public void run() < img.post(new Runnable() < @Override public void run() < img.setImageResource(R.drawable.india1); >>); > >).start(); > >); bt2.setOnClickListener(new View.OnClickListener() < @Override public void onClick(View v) < new Thread(new Runnable() < @Override public void run() < img.post(new Runnable() < @Override public void run() < img.setImageResource(R.drawable.india2); >>); > >).start(); > >); > >

• So now the Coding part is also completed.
• Now run the application to see the output.

Note: Before Running the Application, Copy the Images given below and Paste it in “app -> res -> drawable” by pressing “right click mouse button on drawable” and selecting the “Paste” option.
