Android Invalidate() only single view

Question

I have 2 views on RelativeLayout

I need to invoke(call) onDraw only single view

when I try view1.invalidate(); it also invoke(call) on

Answer 1

I met the same question.

Finally, I found that drawing cache is disabled in android 2.3. Because of no cache, each time the view will redraw itself even the other invalidated.

To make cache enable, use:

setDrawingCacheEnabled(true)

The question is too old, but google put it first when I searched. I think it is useful for others who get into here.
