title: Android: Bottom Button Bar in PrefernceActivity?
body: <p>I'd like to create a PreferenceActivity with a button bar at the bottom, should look like the picture on the right. Anyone know how to do this? I came across this: <a href="https://stackoverflow.com/questions/3795923/bottom-button-bar-in-android">Bottom button bar in android</a>, but it doesn't work in a Preference screen</p>
