[android-beginners] How do I implement the onClick method for a DialogPreference?

[Nick]

I have implemented onSharedPreferenceChanged in my Preference
Activity, which works for other preference settings but it won't get
triggered when I click on the DialogPreference.  I have also tried to
add set the OnPreferenceClickListener to the DialogPreference, which
also works, but this gets triggered as soon as I click on the
preference screen and not on one of the buttons in the actual dialog
window.

I would like to somehow implement the onClick method but don't know
where to do this.

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);

            // Load the preferences from an XML resource
            addPreferencesFromResource(R.xml.preferences);

            mfactory = (DialogPreference)findPreference
("pref_factory");
            mfactory.setOnPreferenceClickListener(new
DialogPreference.OnPreferenceClickListener() {

                        @Override
                        public boolean onPreferenceClick(Preference preference) 
{
                                Log.i(LOG, "onPreferenceClick1 entered");

                                // TODO Auto-generated method stub
                                return false;
                        }});
        }

        @Override
        protected void onResume() {
                super.onResume();
                Log.i(LOG, "onResume entered");

                // Add a Listener
                getPreferenceScreen().getSharedPreferences
().registerOnSharedPreferenceChangeListener(this);
        }

        @Override
        protected void onPause() {
                super.onPause();
                Log.i(LOG, "onPause entered");

                // Remove the Listener
                getPreferenceScreen().getSharedPreferences
().unregisterOnSharedPreferenceChangeListener(this);
        }

        public void onSharedPreferenceChanged(SharedPreferences
sharedPreferences, String key) {
                Log.i(LOG, "onSharedPreferenceChanged entered");

                }
        }
}
