Android :: Implement OnClick For DialogPreference?

I have a DialogPreference in my Preference Activity and would like to know which button was pressed. I have implemented the OnSharedPreferenceChangeListener which does not seem to get triggered when the DialogPreference is selected. I have also tried OnPreferenceClickListener but this gets triggered as soon as the DialogPreference is clicked from the main screen and not when one of the actual dialog buttons was pressed.

I have looked at the API Demo code and it shows how to create the dialog but not how to determine which button was pressed.

public class Preferences extends PreferenceActivity implements OnSharedPreferenceChangeListener {

private static final String LOG = "test"; private DialogPreference mfactory;

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