Fehler initialisieren google maps android recyclerview

Question

Ich versuche, eine Karte als ein Element für eine RecyclerView hinzuzufügen, die in einem Fragment goinjg aufgeblasen wird. Ich initialisiere die Karte in der ViewHolder-Klasse, in der Konstruktormethode habe ich die mMapView.onCreate(null); und mMapView.getMapAsync(this); Methoden verwendet. Dieser Fehler tritt beim Betrieb der Anwendungen:

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.android.chimera.Fragment" on path: DexPathList[[zip file "/data/data/com.google.android.gms/app_chimera/m/00000006/DynamiteModulesB_GmsCore_prodmnc_xhdpi_release.apk"],nativeLibraryDirectories=[/data/user/0/com.google.android.gms/app_chimera/m/00000006/n/arm64-v8a, /system/lib64, /vendor/lib64]] 

Im using these libraries from the support lib:com.google.android.gms:play-services:10.2.1, 'com.google.android.gms:play-services-maps:10.2.1', 'com.android.support:recyclerview-v7:25.3.0', 'com.android.support:appcompat-v7:25.3.0', 'com.android.support:support-v4:25.3.0', 'com.android.support:design:25.3.0'. 

Irgendwelche Ideen für diese Behandlung?

 
    class ListingsAdapter extends RecyclerView.Adapter { 

    private final EarthquakesResponse itemResponse; 

    ListingsAdapter() { 
     itemResponse = new EarthquakesResponse(); 
    } 

    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     final View view = LayoutInflater.from(parent.getContext()) 
       .inflate(R.layout.item_listings_earthquake, parent, false); 
     return new ViewHolder(parent.getContext(), view); 
    } 

    @Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 
     final Feature itemDetail = itemResponse.getFeatures().get(position); 
     holder.prepareItem(itemDetail); 
    } 

    @Override 
    public int getItemCount() { 
     return itemResponse.getMetadata() != null ? itemResponse.getMetadata().getCount() : 0; 
    } 

    void changeResponseData(@NonNull EarthquakesResponse newResponse) { 
     final EarthquakeDiffCallback callback 
       = new EarthquakeDiffCallback(this.itemResponse, newResponse); 
     final DiffUtil.DiffResult diffResult = DiffUtil.calculateDiff(callback); 

     this.itemResponse.setMetadata(newResponse.getMetadata()); 
     this.itemResponse.setBbox(newResponse.getBbox()); 
     this.itemResponse.setFeatures(newResponse.getFeatures()); 
     this.itemResponse.setType(newResponse.getType()); 

     diffResult.dispatchUpdatesTo(this); 
    } 


    @Override 
    public void onViewRecycled(ViewHolder holder) { 
     super.onViewRecycled(holder); 
     if (holder.mMap != null) { 
      holder.mMap.clear(); 
      holder.mMap.setMapType(GoogleMap.MAP_TYPE_NONE); 
     } 
    } 

    class ViewHolder extends RecyclerView.ViewHolder implements OnMapReadyCallback { 

     private final Context mContext; 
     private final TextView mItemTitle; 
     private MapView mLocation; 
     private GoogleMap mMap; 

     ViewHolder(Context context, View itemView) { 
      super(itemView); 
      this.mContext = context; 
      this.mItemTitle = (TextView) itemView.findViewById(R.id.textview_itemlisting_title); 
      mLocation = (MapView) itemView.findViewById(R.id.mapview_itemlisting_location); 
      if (mLocation != null) { 
       mLocation.onCreate(null); 
       mLocation.getMapAsync(this); 
      } 
     } 

     void prepareItem(@NonNull Feature itemDetail) { 
      mItemTitle.setText(itemDetail.getProperties().getPlace()); 
      setMapLocation(itemDetail); 
     } 

     private void setMapLocation(@NonNull Feature itemDetail) { 
      final List coordinates = itemDetail.getGeometry().getCoordinates(); 
      LatLng location = new LatLng(coordinates.get(1), coordinates.get(0)); 
      mMap.clear(); 
      mMap.addMarker(new MarkerOptions().position(location)); 
      mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(location, 8f)); 
     } 

     @Override 
     public void onMapReady(GoogleMap googleMap) { 
      this.mMap = googleMap; 
      MapsInitializer.initialize(this.mContext); 
      this.mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
      googleMap.getUiSettings().setMapToolbarEnabled(false); 

     } 
    } 
} 

Answer 1

Sie das Hinzufügen einiger Klasse „com.google.android.chimera.Fragment“ in Ihrem xml, die nicht durch Ihre Anwendung zu finden ist. Sie können unter XML-Code in Ihr Fragment für die Karte einfügen.

<fragment 
    android:id="@+id/map" 
    class="com.google.android.gms.maps.SupportMapFragment" 
    android:layout_width="match_parent" 
    android:layout_height="350dp" />
