Maybe you can try like this, I had troubles doing it normal way but with "animation" it was ok.

AlphaAnimation alpha = new AlphaAnimation(0.5F, 0.5F); // change values as you want
alpha.setDuration(0); // Make animation instant
alpha.setFillAfter(true); // Tell it to persist after the animation ends
// And then on your imageview
