Create a Compound Widget for Android Lollipop: Part 1

This is the first in a four part article detailing the implementation of a compound widget for Android Lollipop. A compound widget is a widget that is made up of other preexisting widgets. Typically a compound widget will hide the properties those sub widgets usually expose and expose its own custom properties instead.

The example I am going to use is to recreate the classic color picker control. The first version of this I remember seeing was on the Commodore Amiga 30 years ago.

I am going to create a simplified version of this that will set one color.
