title: How to disable PreferenceFragment transparency?
body: <p>I guess it's ok to set background color in some average fragment with average layout, but here I've got <code>PreferenceFragment</code>, which layout (<code>PreferenceScreen</code>) doesn't support <code>android:background</code> field. What's a neat way to handle it?</p>
