Karten in Android CardView im Recycler Anzeigen

Question

Ich versuche, eine Kartenansicht in einer Recycler-Adapter-Ansicht aufzublasen, und ich bekomme einen Fehler, wie sie ist keine solche Instanz wie kasualjob, die ich bin. Hier ist mein Adapter

public class KasualJobAdapter extends RecyclerView.Adapter<KasualJobAdapter.MyViewHolder> { 
    private GoogleMap mMap; 
    protected LatLng mMapLocation; 
    private List<KasualJob> kasualjobList; 
    private FragmentManager fragmentmanager; 

    public KasualJobAdapter(List<KasualJob> kasualjobList, FragmentManager fragmentmanager) { 
     this.kasualjobList = kasualjobList; 
     this.fragmentmanager = fragmentmanager; 
    } 
    public class MyViewHolder extends RecyclerView.ViewHolder { 
     public TextView kasualjobtitle, kasualjobdescription, kasualjoblocation, kasualjobdateposted, kasualjobuser; 
     public SupportMapFragment kasualjobmap; 

     public MyViewHolder(final View view) { 
      super(view); 

      kasualjobtitle = (TextView) view.findViewById(R.id.textview_kasual_job_name); 
      kasualjobdescription = (TextView) view.findViewById(R.id.textview_kasual_job_description); 
      kasualjoblocation = (TextView) view.findViewById(R.id.textview_kasual_job_location); 
      kasualjobdateposted = (TextView) view.findViewById(R.id.textview_kasual_job_date_time_posted); 
      kasualjobuser = (TextView) view.findViewById(R.id.textview_kasual_job_user); 

      kasualjobmap = (SupportMapFragment)fragmentmanager.findFragmentById(R.id.kasual_job_mapview); 

      kasualjobmap.getMapAsync(new OnMapReadyCallback() { 
       @Override 
       public void onMapReady(GoogleMap googleMap) { 
        mMap = googleMap; 

        // Add a marker in Sydney and move the camera 
        LatLng sydney = new LatLng(-34, 151); 
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney")); 
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney)); 
       } 
      }); 
     } 

     public void setMapLocation(double lat, double lon) { 
      mMapLocation = new LatLng(lat, lon); 

      if (mMap != null) { 
       updateMapContents(); 
      } 
     } 

     protected void updateMapContents() { 
      mMap.clear(); 
      // Update the mapView feature data and camera position. 
      mMap.addMarker(new MarkerOptions().position(mMapLocation)); 
      CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(mMapLocation, 10f); 
      mMap.moveCamera(cameraUpdate); 
     } 

    } 

    @Override 
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View itemView = LayoutInflater.from(parent.getContext()) 
       .inflate(R.layout.kasual_job_card_view, parent, false); 

     return new MyViewHolder(itemView); 
    } 

    @Override 
    public void onBindViewHolder(MyViewHolder holder, int position) { 
     KasualJob kasualJob=kasualjobList.get(position); 
     holder.kasualjobtitle.setText(kasualJob.getKasualjobtypename()); 
     holder.kasualjobdescription.setText(kasualJob.getKasualjobdescription()); 
     holder.kasualjoblocation.setText("For Know its Utalii,Nairobi,Kenya"); 
     holder.setMapLocation(kasualJob.getKasualjoblatitude(), kasualJob.getJoblongitude()); 
     holder.kasualjobdateposted.setText("On " + kasualJob.getKasualjobdatetimeposted()); 
     holder.kasualjobuser.setText("By " + kasualJob.getUserfirstname()+ " "+ kasualJob.getUserlastname()); 
    } 

    @Override 
    public int getItemCount() { 
     return kasualjobList.size(); 
    } 
} 

Kann mir bitte jemand helfen, so dass ich die Karten machen kann, und wenn möglich, mir zu erklären, was ich falsch mache

Answer 1

try

holder.kasualjobmap.getMapAsync(new OnMapReadyCallback() { 
     @Override 
     public void onMapReady(GoogleMap googleMap) { 
      mMap = googleMap; 

      // Add a marker in Sydney and move the camera 
      LatLng sydney = new LatLng(-34, 151); 
      mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney")); 
      mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney)); 
     } 
    }); 

zu bewegen

In die Methode onBindViewHolder.
