I'm trying to find out how to get the invalid region of a view in the onDraw callback. What I've got is a view that derives from ImageView. I want to invalidate just a part of that view defined by coordinates that I pass to the postInvalidate function.
In my onDraw callback how do I get hold of the rectangle that defines the rectangle that was passed to postInvalidate? Every time that my onDraw is called the rectangle that is returned from canvas.getClipBounds is always 0,0,width,height despite the postInvalidate function taking a rectangle that is not the entire width and height of the view. Is the getClipBounds function the correct way to get hold of the invalid region? Are there some special flags that need to be set on a view so that an invalid region actually is respected?
