ShaderFactory


abstract class ShaderFactory
kotlin.Any
   ↳ 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 android.graphics.Shader, such as a android.graphics.LinearGradient.
