Thanks, Adam. It seems that onSizeChanged is the way to go. I can cache the last width passed in onSizeChanged and only trigger new work if the width changes. I'm glad you pointed out that onSizeChanged can be called with 0 width; I wouldn't want to do any work in response to that!
Just to be clear, though, when I mentioned doing something in onDraw, it was the following: retrieve the current width; check that the height calculations were valid for that width; if so, proceed with normal rendering; if not, then fire up a background thread to update the height and skip rendering. I was never thinking about doing the height calculation in onDraw itself. (I gather that both you and Blake had that impression.) Your point about the frequency with which onDraw may be called suggests, however, that if I can keep this test out of onDraw it might be better. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
