body: <p>I have a preferncescreen page for showing of data only and not saving it for setting</p>
  
  <p>the code is as below</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="Member Subscription Status"&gt;
  
  
          &lt;PreferenceScreen
      android:title="Subscription Status"
      android:summary="Active"&gt;
  &lt;/PreferenceScreen&gt; 
  
          &lt;PreferenceScreen
      android:title="Next Payment Date"
      android:summary="2012-06-21 18:00:00s"&gt;
  &lt;/PreferenceScreen&gt; 
          &lt;PreferenceScreen
      android:title="Plan Type"
      android:summary="Family"&gt;
  &lt;/PreferenceScreen&gt; 
      &lt;/PreferenceCategory&gt;
  
  
  &lt;/PreferenceScreen&gt;
