Set Screen orientation programmatically

By calling setRequestedOrientation() method, we can set screen orientation programmatically.

Set Screen in Portrait programmatically
Set Screen in Landscape programmatically

package com.exercise.AndroidOrientation;

import android.app.Activity;
import android.content.pm.ActivityInfo;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class AndroidOrientationActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

Button buttonSetPortrait = (Button)findViewById(R.id.setPortrait);
Button buttonSetLandscape = (Button)findViewById(R.id.setLandscape);

buttonSetPortrait.setOnClickListener(new Button.OnClickListener(){

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}});

buttonSetLandscape.setOnClickListener(new Button.OnClickListener(){

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}});
}
}
