Attributes

Remarks

Updates the Paint object used with the current layer (used only if the current layer type is not set to #LAYER_TYPE_NONE). Changed properties of the Paint provided to #setLayerType(int, android.graphics.Paint) will be used the next time the View is redrawn, but #setLayerPaint(android.graphics.Paint) must be called to ensure that the view gets redrawn immediately.

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 1.0 by calling #setAlpha(float), the alpha value of the layer's paint is superseded by this view's alpha value.
