Class PositionableGradientDrawable

  • public class PositionableGradientDrawable
extends android.graphics.drawable.Drawable
    A Drawable with a color gradient for buttons, backgrounds, etc.

    Tweaked for Batch: No XML support, added support for setting the color positions Tinting is also broken, due to private APIs
