If I understand you correctly, you want to add a preference to pick a contact from the phone contact list. There is no direct support for it, i.e. there is no ContactPreference. You could create your own preference by extending DialogPreference. Calling the standard PICK_CONTACT action may help.

hmm yes,

this is from the sample api docs,

 public class List3 extends ListActivity {

         @Override
         protected void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);

             // Get a cursor with all phones
             Cursor c = getContentResolver().query(Phones.CONTENT_URI,
     null, null, null, null);
             startManagingCursor(c);

             // Map Cursor columns to views defined in
     simple_list_item_2.xml
             ListAdapter adapter = new SimpleCursorAdapter(this,
                     android.R.layout.simple_list_item_2, c, 
                             new String[] { Phones.NAME, Phones.NUMBER }, 
                             new int[] { android.R.id.text1,
     android.R.id.text2 });
             setListAdapter(adapter);
         }   
 }
