PreferenceActivity has missing icon on Honeycomb

I've created a simple PreferenceActivity containing a ListActivity. (code added at the end for completeness) but it shows up differently on a 2.3 device and on a Galaxy Tab 10.1" (Android 3.2) (see images below).

My questions are:

• Can I also get the icon with the right arrow in Honeycomb?
  


• Can I avoid the empty black line between the title of the activity and the ListPreference
  

public class TestPreference extends PreferenceActivity

{

@Override

protected void onCreate(Bundle savedInstanceState)

{

    super.onCreate(savedInstanceState);

    setPreferenceScreen(createPreferenceHierarchy());  

}



private PreferenceScreen createPreferenceHierarchy() 

{

    // Root

    PreferenceScreen root = getPreferenceManager().createPreferenceScreen(this);

    /*

     * select language

     */

    ListPreference listPref = new ListPreference(this);     

    listPref.setKey("Language");

    listPref.setEntries(new String[]{"eng", "fra"});

    listPref.setEntryValues(new String[]{"eng", "fra"});

    listPref.setValue("eng");//TODO: assumes English is a supported language!?

    listPref.setSummary("You can select your language here");

    listPref.setTitle("Select Language");

    root.addPreference(listPref);





    return root;

}

}
