title: finding the correct style in R.attr
body: <p>using:</p>
  
  <pre><code>android:textAppearance="?android:attr/...."
  </code></pre>
  
  <p>I would like to style a <code>TextView</code> to look like the default style of the "summary" attribute within a <code>PreferenceScreen</code>.</p>
  
  <p>using the styles from <a href="http://developer.android.com/reference/android/R.attr.html" rel="nofollow">this official list</a>, I have tried <code>"summary"</code> and <code>"summaryOn"</code>, but neither of them looks like the default style for summaries. Can anyone explain why, or suggest which one I should be using?</p>
