ShapeDrawable.ShaderFactory
extends Object
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.

resize
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 |
