I have a tab based app that basically has several tabs that are nothing more than scrollviews containing imageviews in them. The scrollviews can scroll, and zoom and all that fun stuff.

The problem I am running into, is that if you are in one tab, and shrink or scroll around in such a way that the image for that view does not fill the screen, the remainder of the screen gets filled up with parts of other images.

SO, how do I tell the ScrollView to make sure that any part of it that is visible beyond the imageview itself that it appear as whitescreen, and not memory clearly from another image.

Any ideas? Examples?
