android - geolocalizacion - Cambio de fragmentos-Fragmento de mapa de Google V2-Se destruyó la actividad Error

map fragment android studio

Question

Tengo una actividad de Maps (SherlockFragmentActivity) que se carga en un fragmento de Maps que tiene 2 botones e interruptores entre mostrar 2 fragmentos diferentes (GoogleMapFragment & ScaleImageViewFragment)

Cuando hago clic en el botón del mapa del expositor, este reemplaza el fragmento, sin embargo, cuando hago clic atrás, aparece el error "java.lang.IllegalStateException: Activity has has destroyed".

Aquí está mi archivo MapsFragment.java:

public class MapsFragment extends SherlockFragment {
Button mHotelMapButton;
Button mExhibitorButton;
GoogleMapFragment mGoogleMapFragment;
ScaleImageViewFragment mScaleImageViewFragment;
static boolean mShowingGoogleMap = true;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {
mShowingGoogleMap = savedInstanceState.getBoolean("showingGoogleMap");
}
mGoogleMapFragment = new GoogleMapFragment();
mScaleImageViewFragment = new ScaleImageViewFragment();
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putBoolean("showingGoogleMap", mShowingGoogleMap);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.maps_fragment, null);
mHotelMapButton = (Button) view.findViewById(R.id.hotel_button);
mExhibitorButton = (Button) view.findViewById(R.id.exhititor_map_button);
mExhibitorButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mShowingGoogleMap = false;
showExhibitorFragment();
}
});
mHotelMapButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mShowingGoogleMap = true;
showGoogleMapFragment();
}
});
return view;
}
@Override
public void onPause() {
super.onPause();
getChildFragmentManager().beginTransaction()
.remove(mGoogleMapFragment)
.remove(mScaleImageViewFragment).commit();
}
@Override
public void onResume() {
super.onResume();
if(mShowingGoogleMap){
showGoogleMapFragment();
}else{
showExhibitorFragment();
}
}
private void showExhibitorFragment(){
getChildFragmentManager().beginTransaction()
.remove(mGoogleMapFragment)
.remove(mScaleImageViewFragment)
.replace(R.id.fragment_placeholder, mScaleImageViewFragment, "scaleImage")
.commit();
}
private void showGoogleMapFragment(){
getChildFragmentManager().beginTransaction()
.remove(mGoogleMapFragment)
.remove(mScaleImageViewFragment)
.replace(R.id.fragment_placeholder, mGoogleMapFragment, "mapFragment")
.commit();
}
}

y mi archivo GoogleMapFragment.java:

public class GoogleMapFragment extends Fragment {
private SupportMapFragment mMapFragment;
private GoogleMap mMap;
private final LatLng PLANET_HOLLYWOOD = new LatLng(36.1100, -115.1710);
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GoogleMapOptions mapOptions = new GoogleMapOptions();
mapOptions.compassEnabled(true).camera(new CameraPosition(PLANET_HOLLYWOOD, 13, 0f, 0f));
mMapFragment = SupportMapFragment.newInstance(mapOptions);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View view = inflater.inflate(R.layout.google_map, container, false);
getChildFragmentManager()
.beginTransaction()
.add(R.id.map_holder, mMapFragment)
.commit();
return view;
}
@Override
public void onPause() {
super.onPause();
getChildFragmentManager().beginTransaction()
.remove(mMapFragment)
.commit();
}
@Override
public void onResume() {
super.onResume();
mMap = mMapFragment.getMap();
if(mMap != null){
mMap.addMarker(new MarkerOptions().position(PLANET_HOLLYWOOD).title("Planet Hollywood"));
}
}
}

He estado golpeando mi cabeza contra la pared durante bastante tiempo tratando de descubrir este error y cómo evitarlo / corregirlo.

Actualizar:

por cierto si cambio a:

getActivity().getSupportFragmentManager()
.beginTransaction()
.add(R.id.map_holder, mMapFragment)
.commit();

en GoogleMapFragment, entonces no obtengo el error, pero no puedo obtener el mapa para establecer el creador ... parece una condición de carrera

Answer 1

Puede solucionar esto, si elimina todos los fragmentos anidados en onDestroyView() :

public void onDestroyView()
{
super.onDestroyView();
Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));
FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
ft.remove(fragment);
ft.commit();
}

E onCreateView() como de costumbre en onCreateView() :

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.map, container, false);
}
