Android onCameraChange in Fragment никогда не называется

Question

Я пытаюсь установить слушателя, чтобы поймать движения камеры, но он не работает. Метод onCameraChange, реализованный Фрагментом, который размещает SupportMapFragment, никогда не вызывается также, если я настроюсь правильно. This similar question мне не помог.

Вот код фрагмента:

public class MapFragment extends Fragment implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, 
    OnMapReadyCallback, GoogleMap.OnCameraChangeListener { 
private static final String TAG = MapFragment.class.getSimpleName(); 
private static final int MY_LOCATION_REQUEST_PERMISSION = 100; 
private static final int ENABLE_LOCATION_REQUEST_PERMISSION = 200; 

private int mShortAnimationDuration; 
private ImageButton checkin; 
private LinearLayout big_checkin; 

private GoogleMap mMap; 
private GoogleApiClient mGoogleApiClient; 
private double mLatitude, mLongitude; 

private SupportPlaceAutocompleteFragment autocompleteFragment; 

public MapFragment() { 
    // Required empty public constructor 
} 


@Override 
public void onCreate(Bundle savedInstanceState) { 
    if (BuildConfig.DEBUG) { 
     Log.d(TAG, "onCreate"); 
    } 
    super.onCreate(savedInstanceState); 

    buildGoogleApiClient(); 


} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    if (BuildConfig.DEBUG) { 
     Log.d(TAG, "onCreateView"); 
    } 
    // Inflate the layout for this fragment 
    final View view = inflater.inflate(R.layout.fragment_map, container, false); 

    final SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map); 
    mapFragment.getMapAsync(this); 

    final DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout); 

    final Toolbar toolbar = (Toolbar) view.findViewById(R.id.map_toolbar); 
    ((AppCompatActivity) getActivity()).setSupportActionBar(toolbar); 

    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
      getActivity(), drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); 
    drawer.addDrawerListener(toggle); 
    toggle.syncState(); 

    autocompleteFragment = (SupportPlaceAutocompleteFragment) 
      getChildFragmentManager().findFragmentById(R.id.place_autocomplete_fragment); 

    return view; 
}

Answer 1

ПОСТАНОВИЛИ. Я просто заметил, что, поскольку я использовал ClusterManager, я настроил его как onCameraChangeListener, который явно переопределил мой собственный метод.
