Pre-creating a Path that depends on View width and height

Question

I have a custom View that draws a complex Path. The dimensions of path elements are calculated using the view width and height. I need a way to pre-create this path before onDraw is called to "Avoid object allocations during draw/layout...", in a moment when the view width and height are already known. What is the proper moment in the View lifecycle to do such pre-creation?

Answer 1

just override View.onSizeChanged and do your initialization there
