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.
