Create a custom style
<p>I'm looking at how to give an app that I develop and deploy it's own look and feel. So I read about the Style and Themes on developer.android.com. After some initial success with text color, text size, background color... I seem to get stuck at changing buttons, toggle buttons... It appears to me that to change the color of a button a .9.png file must be created (possibly for the different dpi's).  Looking at the artwork in the default style, I see a large number of these .9.png files. To have a consistent style they should all be updated.</p>

<p>Is it correct to say that defining a new style involves modifying/recreating the .9.png files?
If no, how should one go about modifying the style of these .9.png based elements?
If so, are there any tools that assist with creating a custom style? And are there any style packages that can be downloaded/purchased?</p>
