Remarks
Specifies the type of layer backing this view. The layer can be #LAYER_TYPE_NONE, #LAYER_TYPE_SOFTWARE or #LAYER_TYPE_HARDWARE.
A layer is associated with an optional android.graphics.Paint instance that controls how the layer is composed on screen. The following properties of the paint are taken into account when composing the layer:
<ul> <li>android.graphics.Paint#getAlpha() Translucency (alpha)</li> <li>android.graphics.Paint#getXfermode() Blending mode</li> <li>android.graphics.Paint#getColorFilter() Color filter</li> </ul>
If this view has an alpha value set to < 1.0 by calling #setAlpha(float), the alpha value of the layer's paint is superseded by this view's alpha value.
Refer to the documentation of #LAYER_TYPE_NONE, #LAYER_TYPE_SOFTWARE and #LAYER_TYPE_HARDWARE for more information on when and how to use layers.
