There is no need to do those extra coding, i have faced this problem and solved it by a single line.

After many hours looking on all the answers in this and other similar questions, i found out very easiest way to do this without extending ListPreference, you can do it in common extends PreferenceActivity, see the code bellow.

public class UserSettingsActivity extends PreferenceActivity 
{
    ListPreference listpref;

    @Override
    public void onCreate(Bundle savedInstenceState)
    {
        super.onCreate(savedInstenceState);
        addPreferencesFromResource(R.xml.settings);
        listpref = (ListPreference)findPreference("prefDefaultCurrency");

        listpref.setOnPreferenceChangeListener(new OnPreferenceChangeListener() 
        {           
            @Override
            public boolean onPreferenceChange(Preference preference, Object value) {
            // TODO Auto-generated method stub

            listpref.setSummary(listpref.getEntries()[Integer.parseInt(value.toString())]);
            return true;
        }
    });

Thats it, with a single line, all you have to do is get value passed from the onPreferenceChange(Preference preference, Object value) parse it to integer and pass it to listpref.setSummary(listpref.getEntries()[Integer.parseInt(value.toString())]);
