Android: How do I circumvent invalidation / redraw of not effected layers?
<p>I have a relative layout with several ImageViews (with transparent areas) above each other. The problem is: if I invalidate one of those, all other's onDraw() methods are called too. Is this normal?
I don't want all Layers (Views) to redraw since this is a big performance issue- I only want the invalidated view to redraw..</p>

<p>Any ideas?</p>
