title: ListPreference default value not showing up
body: <p>I tried to set the default value for a ListPreference but nothing shows up.</p>
  
  <p>Can you check my code for any errors?</p>
  
  <p>Thanks.</p>
  
  <p>Truly,
  Emad</p>
  
  <p>This is in the settings.xml file:</p>
  
  <pre><code>&lt;PreferenceCategory android:title="Media:"&gt;
      &lt;CheckBoxPreference android:key="ChimeWhenMusicIsPlaying"
          android:title="@string/ChimeWhenMusicIsPlayingTitle" android:summary="@string/ChimeWhenMusicIsPlayingSummary"
          android:defaultValue="false" /&gt;
  
      &lt;ListPreference android:title="Chime Volume"
          android:key="ChimeVolume" android:summary="Select volume for the chiming sound."
          android:entries="@array/chimeVolumeLabels" android:entryValues="@array/chimeVolumeValues"
          android:defaultValue="1" /&gt;
  
  &lt;/PreferenceCategory&gt;
  </code></pre>
  
  <p>This is in the arrays file:</p>
  
  <pre><code>&lt;resources&gt;
  
      &lt;string-array name="chimeVolumeLabels"&gt;
      &lt;item&gt;Default&lt;/item&gt;
      &lt;item&gt;Soft&lt;/item&gt;
      &lt;item&gt;Medium&lt;/item&gt;
      &lt;item&gt;Loud&lt;/item&gt;
      &lt;/string-array&gt;
  
      &lt;string-array name="chimeVolumeValues"&gt;
      &lt;item&gt;1&lt;/item&gt;
      &lt;item&gt;2&lt;/item&gt;
      &lt;item&gt;3&lt;/item&gt;
      &lt;item&gt;4&lt;/item&gt;
      &lt;/string-array&gt;
  &lt;/resources&gt;
  </code></pre>
