public static abstract class 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.

Summary

Public constructors

ShaderFactory()

Public methods

abstract Shader resize(int width, int height)

Returns the Shader to be drawn when a Drawable is drawn.

Inherited methods

From class java.lang.Object

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

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
Shader the Shader to be drawn
