How to change button colors on Android?
<p>I'm a designer and about to do some light redesign of the standard components on Android. Right now I'm trying to figure out how button states works. According to Material Design guidelines the standard buttons, Floating action button, Raised and Flat buttons, have four states: Normal, Focus, Pressed and Disabled. </p>

<ul>
<li>If I only specify a color for the Normal state – will the system choose colors based on that value for the other states? Is this true for other interactive elements as well such as drop downs?   </li>
<li>Can I (easily) apply customized colors for the other states?  </li>
</ul>
