HexDrawable

Optional background Drawable for children of a HexGridView that gives them the same shape as the View's grid hexagon.

For normal usage, you don't need to deal with this class at all, directly. The app:layout_hexBackground* attributes are available to apply this feature from layout XML, and the HexGridView.applyHexBackground function offers the same options in code. If you extend this class, you'll need to instantiate and set the drawable manually, but you still must use applyHexBackground to modify the inset or color.

The current implementation simply fills its area with a solid color, and sets its Outline to the grid View's hexagon shape, so that it can cast material shadows. The inset is accounted for during child layout, so this class is expected to draw right up to its bounds.

It is open to allow further customizations, like possibly using a Shader with the Paint instead of a solid color.
