The view drawing cache was mainly produced obsolete Along with the introduction of components-accelerated rendering in API 11. With hardware-acceleration, intermediate cache levels are mainly unnecessary and can easily cause a Web decline in overall performance on account of the expense of creating and updating the layer. Within the uncommon cases where by caching layers are beneficial, like for alpha animations, setLayerType(int, android.graphics.Paint) handles this with hardware rendering.

There exists a kind of the constructor that are referred to as once the view is made from code and a sort that is called when the view is inflated from a layout file. The next kind should parse and utilize any characteristics defined inside the format file. onFinishInflate()

Returns the remaining padding of the view. If there are actually inset and enabled scrollbars, this price may well incorporate the Room necessary to Show the scrollbars also.
