title: Referencing a string in a string array resource with xml
body: <p>I have preferences where you can enable/disable what items will show up on the menu.  There are 17 items.  I made a string array in values/arrays.xml with titles for each of these 17 items.</p>
  
  <p>I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.</p>
  
  <p>How can I do this?</p>
  
  <p>In the Android developer reference, I see how I can reference a single string with XML, but not how I can reference a string from an array resource in XML.</p>
