사용자 정보

Question

나는이 내가 시도 할 것입니다 MarkerCluster

를 사용하여 각 마커에 대해 서로 다른 값으로 사용자 정보창을 렌더링하기 위해 노력하고 있어요 :

private final GoogleMap.InfoWindowAdapter mInfoWindowAdapter = new GoogleMap.InfoWindowAdapter() { 
     @Override 
     public View getInfoWindow(Marker marker) { 
      View window = null; 
      if(getActivity()!=null&&isAdded()){ 
       window = getActivity().getLayoutInflater().inflate(R.layout.map_objective_overlay, null); 
       final CustomFontTextView nameTV = (CustomFontTextView) window.findViewById(R.id.nameTV); 

       if(clickedClusterItem!=null){ 
        System.out.println("You clicked this: "+clickedClusterItem.getName()); 
       }else{ 
        System.out.println("The clicked cluster item was nulllll"); 
       } 
       if (clickedCluster != null) { 
        for (Objective item : clickedCluster.getItems()) { 
         // Extract data from each item in the cluster as needed 
         if(item.getRemoteId().equals(clickedClusterItem.getRemoteId())){ 
          nameTV.setText(clickedClusterItem.getName()); 
         } 
        } 
       } 
      } 
      return window; 
     } 

     @Override 
     public View getInfoContents(Marker marker) { 
      return null; 
     } 
    }; 
    private Objective clickedClusterItem; 
    private Cluster<Objective> clickedCluster; 

@Override 
    public void onResume() { 
     super.onResume(); 
     preferences = getActivity().getSharedPreferences(Constants.PREFS_NAME, Context.MODE_PRIVATE); 
     if (map == null) { 
      map = fragment.getMap(); 
      mClusterManager = new ClusterManager<Objective>(getActivity(), map); 
      map.setOnCameraChangeListener(mClusterManager); 
      map.setOnMarkerClickListener(mClusterManager); 
      latitude = Double.parseDouble(preferences.getString(Constants.LATITUDE, "0")); 
      longitude = Double.parseDouble(preferences.getString(Constants.LONGITUDE, "0")); 
      map.addMarker(new MarkerOptions() 
        .position(new LatLng(latitude, longitude)) 
        .title("Hello " + preferences.getString(Constants.TOURIST_NAME, "tourist")) 
        .snippet("You are here") 
        .icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_check_in))); 
      map.setInfoWindowAdapter(mClusterManager.getMarkerManager()); 
      //mClusterManager.setRenderer(new ObjectiveClusterRenderer(getActivity(), map, mClusterManager)); 
      mClusterManager.getClusterMarkerCollection().setOnInfoWindowAdapter(mInfoWindowAdapter); 
      mClusterManager.getMarkerCollection().setOnInfoWindowAdapter(mInfoWindowAdapter); 
      map.setOnMarkerClickListener(mClusterManager); 

      mClusterManager.setOnClusterClickListener(new ClusterManager.OnClusterClickListener<Objective>() { 
       @Override 
       public boolean onClusterClick(Cluster<Objective> cluster) { 
        clickedCluster = cluster; // remember for use later in the Adapter 
        return false; 
       } 
      }); 
      mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<Objective>() { 
       @Override 
       public boolean onClusterItemClick(Objective item) { 
        clickedClusterItem = item; 
        return false; 
       } 
      }); 

그리고 여기가 clustermanager에 마커를 추가 :

public void setUpClusterer(List<Objective> objectivesList) { 
     map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(latitude, longitude), 10)); 
     addItems(objectivesList); 
    } 

    private void addItems(List<Objective> objectiveList) { 
     for (Objective anObjectiveList : objectiveList) { 
      Objective offsetItem = new Objective(); 
      offsetItem.setRemoteId(anObjectiveList.getRemoteId()); 
      offsetItem.setName(anObjectiveList.getName()); 
      objectiveMap.put(offsetItem.getRemoteId(), offsetItem); 
      System.out.println("This is the remote ID: " + offsetItem.getRemoteId()); 
      mClusterManager.addItem(offsetItem); 
     } 
    } 

InfoWindow의 레이아웃은 괜찮지 만, 내용은 null의 경우 clickedClusterItem 및 clickedCluster은 항상 null입니다 ...

내가 잘못했을 수있는 것에 대한 힌트가 있습니까?

마커와 해당 개체가있는지도를 만드는 데 관련된 몇 가지 답변이 있지만 그 방법을 잘 모르겠습니다.

내 앱에서이 작업을 수행했습니다. 너의 안에 이것을 시험해 보라.

는 다음과 같은 방법을 고려할 수는 나를 위해 일하는 : 어떤 클러스터 러 라이브러리는

public void initilizeMap() { 
    googleMap = mFragment.getMap(); 
    googleMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN); 
    googleMap.getUiSettings().setZoomControlsEnabled(true); // true to`enter code here` 
    googleMap.getUiSettings().setZoomGesturesEnabled(true);

    googleMap.getUiSettings().setMyLocationButtonEnabled(true); 
    googleMap.getUiSettings().setRotateGesturesEnabled(true); 
    if (googleMap == null) { 
     Toast.makeText(getActivity(), "Sorry! unable to create maps", 
       Toast.LENGTH_SHORT).show(); 
    } 
    mClusterManager = new ClusterManager<MyItem>(getActivity(), googleMap); 
//   googleMap.setInfoWindowAdapter(new CustomInfoWindowAdapter()); 
    googleMap.setOnMapLoadedCallback(this); 
    googleMap.setMyLocationEnabled(true); 
    googleMap.setBuildingsEnabled(true); 
    googleMap.getUiSettings().setTiltGesturesEnabled(true); 

    MyItem offsetItem = new MyItem(Double.parseDouble(outletList.get(i).getMap_latitude()), 
             Double.parseDouble(outletList.get(i).getMap_longitude()), title , address); 
     mClusterManager.addItem(offsetItem); 
     googleMap.setInfoWindowAdapter(new CustomInfoWindowAdapter(offsetItem)); 

} 

private class CustomInfoWindowAdapter implements InfoWindowAdapter { 
    Marker marker;

    public CustomInfoWindowAdapter(MyItem item) { 
    view = getActivity().getLayoutInflater().inflate(
