title: PreferenceFragmentCompat requires preferenceTheme to be set
body: <p>With the new PreferenceFragmentCompat from the v7 Preference Support Library: <a href="http://developer.android.com/tools/support-library/features.html#v7-preference">http://developer.android.com/tools/support-library/features.html#v7-preference</a>, I get this error</p>
  
  <pre><code>E  java.lang.IllegalStateException: Must specify preferenceTheme in theme
  E      at android.support.v7.preference.PreferenceFragmentCompat.onCreate(PreferenceFragmentCompat.java:202)
  </code></pre>
  
  <p>What theme should be set?</p>
  
  <p><strong>Update:</strong> I have tried using</p>
  
  <p><code>&lt;item name="preferenceTheme"&gt;@style/PreferenceThemeOverlay&lt;/item&gt;</code></p>
  
  <p>as suggested by @Bogato but it doesn't look right and looks very Holo even on Lollipop.</p>
