Android Styles and Themes

Here is source code of the Program to Define a Style and Apply to a View in Android using java. The program is successfully compiled and run on a Windows system using Eclipse Ide. The program output is also shown below.

In order to Define a Style and Apply to a View i have defined a style for my text view in /res/drawable folder with name mystyle and applied this as a background to my Edittextview , the following code demonstrates this.

Main Activity

package com.example.text_view_rounded;
 
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
 
public class MainActivity extends Activity {
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
 
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
 
}
