Really? *immediately*? I thought that invalidate() must be called on the UI thread. But invalidate() does not draw your view *immediately*, does it? I thought it will schedule a draw 'action' as soon as the UI-message thread gets a chance. If you call multiple invalidate()-s in a row, your view is redrawn only once (all the invalidate-rects are gathered and the redraw is using the union of all these rects).
The postInvalidate() can be called from a non UI-thread. It just posts an invalidate() on the UI-thread.
