<h3 id="DrawableTinting">DrawableTinting</h3>

<p>Sample that shows applying tinting and color filters to Drawables both programmatically

and as Drawable resources in XML.</p>

<p>Tinting is set on a nine-patch drawable through the "tint" and "tintMode" parameters.

A color state list is referenced as the tint color, which defines colors for different

states of a View (for example disabled/enabled, focused, pressed or selected).</p>

<p>Programmatically, tinting is applied to a Drawable through its "setColorFilter" method,

with a reference to a color and a PorterDuff blend mode. The color and blend mode can be

changed from the UI to see the effect of different options.</p>
