Force full screen and rotate landscape Android

The following example is to force Android screen to become full screen programmatically. And to rotate into lanscape mode.

public class HijrahRasul_mula extends Activity {

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //no big screen title + icon
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        //full screen without notification bar
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        //this is to force layout to landscape - for potrait chage to SCREEN_ORIENTATION_POTRAIT
        this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        setContentView(R.layout.activity_hijrah_rasul_mula);
    }
}

 

There’s another alternative method by setting the Activity theme.

<application 
    android:icon="@drawable/icon" 
    android:label="@string/app_name" 
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
