[SOLVED] Set Screen Orientation Programmatically

There are times where you need to ensure that your application is displayed only in a certain orientation. For example, suppose you are writing a game that should only be viewed in landscape mode. In this case, you can programmatically force a change in orientation using the setRequestOrientation() method of the Activity class:

package net.learn2develop.OrientationAware;
import android.app.Activity;
import android.content.pm.ActivityInfo;
import android.os.Bundle;

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

        //---change to landscape mode---
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    }
}

To change to portrait mode, use the ActivityInfo.SCREEN_ORIENTATION_PORTRAIT constant:

        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
