I'm developing an App with lot's of custom views and ran into performance issues with a quite complex one of them. The time they take for measuring and drawing is to high (>= 30ms typical). To give some more details: It's a custom ViewGroup (extending RelativeLayout) with custom Views (extending RelativeLayout although) as it's children.
So I'm it came across my mind what might be the better/quicker approach for getting rid of this performance problems: Optimize the children and layouts or switch to a completely custom drawn view (lines, rectangles and stuff like these)?
Do any of you have experience in one or another? Or even some done some benchmarks and is willing to share them?
