What I mean is that if you have so many views that it's negatively impacting your application, you should try to reduce the number of views. > Dare I disagree?

Instead of trying to optimize further you should figure out exactly why they are drawn so often. There is definitely nothing in the UI toolkit that will redraw all visible views when "there is not enough time to redraw some view." That's just not how the UI toolkit works. > The code of drawChild() is complicated and does a lot of things that I do > not need. That was the reason of my question. It is complicated but in the common case most of that code is skipped. It's only triggered when you use animations. Have you profiled your app to see how much you would save? I really get the feeling that you are trying to optimize things that are just not worth it when you should try to re-architecture the UI to be simpler. Or that you should at least try to understand what exactly is causing your numerous redraws. -- Romain Guy Android framework engineer romain...@android.com Note: please don't send private questions to me, as I don't have time to provide private support.
