我正在尝试使用MarkerCluster
这是我尝试的：
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;
}
});
在这里我将标记添加到clustermanager：
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);
}
}
InfoWindow的布局没问题，但内容为空clickedClusterItem且clickedCluster始终为空...
有关我可能做错的任何提示？
我看到其他一些答案涉及使用标记和相应的对象创建Map，但我不太清楚如何做到这一点。

我在我的应用中做到了这一点。试试吧。

您可以考虑以下方法为我工作：
public void initilizeMap() {
googleMap = mFragment.getMap();
googleMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
googleMap.getUiSettings().setZoomControlsEnabled(true); // true to`enter code here`

googleMap.getUiSettings().setCompassEnabled(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;

marker.hideInfoWindow();
marker.showInfoWindow();
}
return null;
}

this.marker = marker;
String url = null;
if (marker.getId() != null && markers != null && markers.size() > 0) {
if (markers.get(marker.getId()) != null

}
}
final ImageView image = ((ImageView) view.findViewById(R.id.badge));
if (url != null && !url.equalsIgnoreCase("null")
&& !url.equalsIgnoreCase("")) {
imageLoader.displayImage(url, image, options,
new SimpleImageLoadingListener() {
@Override
public void onLoadingComplete(String imageUri, View view,

super.onLoadingComplete(imageUri, view, loadedImage);

}
});
} else {
image.setImageResource(R.drawable.ic_launcher);
}
