Class OnScrollDispatchHelper

  • 
public class OnScrollDispatchHelper

    Android has a bug where onScrollChanged is called twice per frame with the same params during flings. We hack around that here by trying to detect that duplicate call and not dispatch it. See https://code.google.com/p/android/issues/detail?id=39473
