Image slide show in Android

I am making an application in android for picture slide show. I have tried the following code:

class MainActivity extends Activity {      
    @Override     
    protected void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState);   
        setContentView(R.layout.activity_main); 
        Drawable backgrounds[] = new Drawable[2];   
        Resources res = getResources();        
        backgrounds[0] = res.getDrawable(android.R.drawable.btn_star_big_on); 
        backgrounds[1] = res.getDrawable(android.R.drawable.btn_star_big_off);         
        TransitionDrawable crossfader = new TransitionDrawable(backgrounds);
        ImageView image = (ImageView)findViewById(R.id.image);
        image.setImageDrawable(crossfader);   
        crossfader.startTransition(3000);      
    }   
}

This code successfully bring the new image on top but previous image is not faded out. Can anyone help me on it?

You need to enable the cross fade on your transition to have both of your images fade. Use the method setCrossFadeEnabled to enable it by setting it tu true.

See documentation here http://developer.android.com/reference/android/graphics/drawable/TransitionDrawable.html#setCrossFadeEnabled(boolean)
