title: Add a seekbar in preferences
body: <p>I've made a preference-list. I get it from the code</p>
  
  <pre><code> addPreferencesFromResource(R.xml.preferencelayout);
  </code></pre>
  
  <p>This gets me to my <code>preferencelayout.xml</code> file as contains the following:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;PreferenceScreen
    xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  
  &lt;PreferenceCategory android:title="Settings"&gt;
  &lt;ListPreference
     android:key="listPref"
     android:title="Shake sensitivity"
     android:summary=""
     android:entries="@array/listArray"
     android:entryValues="@array/listValues"
     android:defaultValue="165" /&gt;
  
  
     &lt;SeekBarPreference
     android:defaultValue="22"
     android:title="Set the default time"
     android:key="seekBar"&gt;
     &lt;/SeekBarPreference&gt;
  
   &lt;CheckBoxPreference
     android:key="checkboxPref"
     android:title="Autodecrease music"
     android:summary=""
     android:defaultValue="true"/&gt;
   &lt;/PreferenceCategory&gt;
   &lt;/PreferenceScreen&gt;
  </code></pre>
  
  <p>When I press the SeekBarPreference button, a dialog comes up with the Seekbar and with 2 buttons, save and cancel!</p>
  
  <p>Here comes my question: </p>
  
  <p>Can I add a textview or something to be shown beside the seekbar to view which value that the seekbar is currently pointing at?</p>
  
  <p>How can I get the value the user has entered?</p>
  
  <p>Thanks!</p>
