Android ArrayList <MyObject> przekazuje jako działkę

Kod teraz zmodyfikowany, aby odzwierciedlić przyjęte rozwiązanie.

Służy teraz jako roboczy przykład przekazania niestandardowej listy ArrayList do DialogFragment.

Przekazuję ArrayList obiektów niestandardowych do DialogFragment za pomocą pakietu na newInstance. Arraylist jest poprawnie odbierany w newInstance. Wywołanie putParcelable wykonuje się poprawnie (bez błędów), ale umieszczenie punktów przerwania w kodzie paczki w obiekcie ArrayList pokazuje, że metody paczki nie są wywoływane podczas ustawiania lub pobierania danych.

Czy poprawię tworzenie klasy LocalityList dla ArrayList i tworzenie tej paczki lub czy sama klasa Locality może być parcelowalna?

DialogFragment

/**
 * Create a new instance of ValidateUserEnteredLocationLocalitySelectorFragment, providing "localityList"
 * as an argument.
 */
public static ValidateUserEnteredLocationLocalitySelectorFragment newInstance(LocalityList localityList) {

    ValidateUserEnteredLocationLocalitySelectorFragment fragmentInstance = new ValidateUserEnteredLocationLocalitySelectorFragment();

    // Supply location input as an argument.
    Bundle bundle = new Bundle();
    bundle.putParcelable(KEY_LOCALITY_LIST, localityList);
    fragmentInstance.setArguments(bundle);

    return fragmentInstance;
}


/**
 * Retrieve the locality list from the bundle
 */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mLocalityList = getArguments().getParcelable(KEY_LOCALITY_LIST);
}


 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.validate_user_entered_location, container, false);

    mLocalityListView = (ListView) view.findViewById(R.id.dialogLocalityListView);
    mAdapter = new SearchLocationLocalitiesListAdapter(getActivity(), mLocalityList);
    mLocalityListView.setAdapter(mAdapter);

    return view;
}
