ShapeDrawable.ShaderFactory


public static abstract class ShapeDrawable.ShaderFactory
extends Object

java.lang.Object
   ↳ android.graphics.drawable.ShapeDrawable.ShaderFactory


Base class defines a factory object that is called each time the drawable is resized (has a new width or height). Its resize() method returns a corresponding shader, or null. Implement this class if you'd like your ShapeDrawable to use a special Shader, such as a LinearGradient.

Added in API level 1
public abstract Shader resize (int width, 
                int height)

Returns the Shader to be drawn when a Drawable is drawn. The dimensions of the Drawable are passed because they may be needed to adjust how the Shader is configured for drawing. This is called by ShapeDrawable.setShape().

Parameters
width int: the width of the Drawable being drawn

height int: the heigh of the Drawable being drawn

Returns
Shader the Shader to be drawn
