The custom view onDraw is constantly called

Question

I have a custom view that I override with the onDraw method to draw bitmaps using canvas.

I cannot post any code because it is quite long and complicated.

I put the log in the onDraw method, and I see that it never ceased to be called.

My question is: what can the onDraw method call, except for calling invalidate on the view or its ancestors?

Answer 1

found a problem. I called getWidth() and getHeight() in the onDraw() method
