You can implement

 public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,
        String key) {
}

if you first register an OnSharedPreferenceChangeListener.

 public class Prefs extends PreferenceActivity implements
    OnSharedPreferenceChangeListener

@Override
protected void onPause() {
    super.onPause();
    getPreferenceScreen().getSharedPreferences()
            .unregisterOnSharedPreferenceChangeListener(this);
}

@Override
protected void onResume() {
    super.onResume();
    getPreferenceScreen().getSharedPreferences()
            .registerOnSharedPreferenceChangeListener(this);
}
