ShapeOfView
Give a custom shape to any android view, Material Design 2 ready
...It supports both predefined shapes (round rects, circles, arcs, bubbles, triangles, stars, polygons, diagonals, cut corners) and fully custom shapes via clipping paths or drawables. Moreover, shapes can be animated (for example, corners gradually changing, or shape morphing), giving developers creative freedom for dynamic UI effects. This library helps in building expressive, modern UI designs aligned with modern design languages (e.g. Material 2 / custom).
