[Splash Screen]How to show an image in full screen?

Question

I want to make a splash screen in my application, for that i need to know how to show an image in full screen. This could me made by XML or Java code ? And how? For now i just made this:

public class SplashScreen extends Activity {

    private static final int STOPSPLASH = 0;

    private static final long SPLASHTIME = 5000;



    private Handler splashHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
    switch (msg.what) {
    case STOPSPLASH:
    //remove SplashScreen from view
    Intent intent = new Intent(SplashScreen.this, jetpack.class);
    startActivity(intent);
    break;
    }
    super.handleMessage(msg);
    }
    };



    @Override

    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash_screen);
    Message msg = new Message();
    msg.what = STOPSPLASH;
    splashHandler.sendMessageDelayed(msg, SPLASHTIME);
    }
    }

How can be this splash_screen.xml ? Thank you for your help.
