Не могу понять почему не работает слушатель на SharedPreferences. Пожалуйста подскажите что сделал не так?

Answer 1

Вы создали лисенер, но ни к чему его не применили, вот он и не работает. Попробуйте сначала инициализировать, потом проставлять

Answer 2

Реализация слушателя изменений в преференсах в фрагменте:

public class MyFragment extends Fragment implements SharedPreferences.OnSharedPreferenceChangeListener {
    SharedPreferences todayWeatherSharedPreferences;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        todayWeatherSharedPreferences = getActivity().getSharedPreferences(SharedPrefHelper.DATA_WEATHER_NOW, 0);
        todayWeatherSharedPreferences.registerOnSharedPreferenceChangeListener(this);
    }
    @Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
    }
}
