change background of an ImageView (the old image stays there!)

Question

how can I change the background of an ImageView from java? I have an ImageView and at a certain point I need to change the image that it displays (set in the styles). I tried to do it like this:

placeHolder.setImageDrawable(myDrawb);

but it looks like the old image remains there and it is partially covered but the new one (which in my case has different shape).

hope you guys can help!

cheers

Answer 1

Clear the background image with:

placeHolder.setBackgroundResource( 0 );

Answer 2

Alternatively you should set the Src of the ImageView in xml instead of setting the Background. I think this is the "right" way anyhow.
