how to change the alpha value of imageview [duplicate]

Question

In my app I want to change the ImageView like the following. I want only to change the image on the body.

I have followed the following link to change the alpha values by using the code like that

imageView.setAlpha(255);

But it is not working.

How to Set Opacity (Alpha) for View in Android. Please anybody suggest me how to do that.

Answer 1

Or, without using animation you can just use setAlpha(float alpha) on your ImageView.

Answer 2

It might be because setAlpha(float Alpha) has been deprecated as of API level 16 by setImageAlpha(float Alpha)
