The view drawing cache was mainly designed obsolete Using the introduction of components-accelerated rendering in API 11. With components-acceleration, intermediate cache levels are mainly pointless and can certainly end in a net loss in overall performance due to the cost of developing and updating the layer. Within the unusual situations where by caching layers are valuable, including for alpha animations, setLayerType(int, android.graphics.Paint) handles this with hardware rendering.
If a nested parent does take in the fling, this view should not scroll at all, even to settle back again to a sound idle place.
