How to clear ImageView correctly?

For example, in my Activity I have such code (I skip the initialization of variables):

ImageView iview; //some ImageView
Bitmap b; //some Bitmap
iview.setImageBitmap(b);

Question is - how to clear iview resources correctly (with or without destroying view) ? Would ImageView free it's resources (used in native code) after b.recycle()?

I suppose, that ImageView doesn't just free it resources after Activity onStop (or onDestroy).

if nothing is working for you try setting the background color of view to layout color.if my layout color is white u can do like this:

 edit_countflag.setBackgroundColor(Color.parseColor("#ffffff"));
//then set the image
 edit_countflag.setImageResource(R.drawable.flag_id);

You can use frequently it works:

imageView.setImageResource(0);

viewToUse.setImageResource(android.R.color.transparent);
  • I think using setImageResource with a color identifier will give you crashing issues on Android 2.2.1, make sure to test it.

no you need to unbindDrawables, you can do it by setting iview.setImageDrawable(null);
