android ics fading edges don't work

Question

somehow fading edges seems not to work for android ics (android 4+) for own views. If I test this layout on a lower android version it paints the fading edge but not on andr

Answer 1

"Using fading edges may introduce noticeable performance degradations and should be used only when required by the application's visual design. To request fading edges with API level 14 and above, use the android:requiresFadingEdge attribute instead"
