如何在没有集群点击的情况下显示信息窗口

Question

Cluster和自定义InfoWindow的问题不大。

我不想在单击群集时显示 Infowindow。 但是当我单击 clusterItem 并单击集群时，我的应用程序会显示 Infowindow。它显示最后一次单击 ClusterItem 的信息窗口。

代码：

public class MapsLActivity extends FragmentActivity implements OnMapReadyCallback, ClusterManager.OnClusterItemClickListener<House>, GoogleMap.OnMapClickListener, ClusterManager.OnClusterClickListener<House>{

private GoogleMap mMap;
private View infoWindow;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps_k);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    mMap.getUiSettings().setZoomControlsEnabled(true);

    ClusterManager<House> mClusterManager = new ClusterManager<>(this, mMap);

    mMap.setOnMapClickListener(this);
    mMap.setOnMarkerClickListener(mClusterManager);
    mMap.setOnCameraChangeListener(mClusterManager);

    AssetManager assetManager = getResources().getAssets();
    try {
        AssetManager.AssetInputStream ais = (AssetManager.AssetInputStream) assetManager.open("yb_edu.json");
        BufferedReader br = new BufferedReader(new InputStreamReader(ais));
        StringBuilder sb = new StringBuilder();

        int bufferSize = 1024 * 1024;
        char readBuf[] = new char[bufferSize];
        int resultSize = 0;

        while ((resultSize = br.read(readBuf)) != -1) {
            if (resultSize == bufferSize) {
                sb.append(readBuf);
            } else {
                for (int i = 0; i < resultSize; i++) {
                    sb.append(readBuf[i]);
                }
            }
        }

        String jString = sb.toString();
        JSONObject object = new JSONObject(jString);
        JSONArray list = new JSONArray(object.getString("yb_edu"));

        for (int i = 0; i < list.length(); i++) {
            JSONObject inside = list.getJSONObject(i);

            String title = inside.getString("title");
            String lats = inside.getString("lat");
            String lngs = inside.getString("lng");

            double lat = Double.parseDouble(lats);
            double lng = Double.parseDouble(lngs);

            LatLng position = new LatLng(lat, lng);

            Log.v("@@@", "postion : " + position);

            Log.v("@@i=@@", String.valueOf(i));

            i++;

            mClusterManager.addItem(new House(position, title));
        }
        mClusterManager.cluster(); //클러스터 새로고침
    } catch (IOException e) {
        e.printStackTrace();
    } catch (JSONException e) {
        e.printStackTrace();
    }

    mClusterManager.setOnClusterItemClickListener(this);
    mClusterManager.setOnClusterClickListener(this);
}

@Override
public boolean onClusterItemClick(final House house) {
    Toast.makeText(this, "onClusterItemClick", Toast.LENGTH_SHORT).show();

    LatLng latLng = house.getLatLng();

    Log.v("@@", "LatLng : " + latLng);

    infoWindow = getLayoutInflater().inflate(R.layout.markerinfo, null);
    mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
        @Override
        public View getInfoWindow(Marker marker) {
            ((TextView)infoWindow.findViewById(R.id.tx_infoWindowTitle)).setText(house.getTitle());
            ((TextView)infoWindow.findViewById(R.id.tx_infoWindowContent)).setText(house.getLatLng().toString());
            return infoWindow;
        }

        @Override
        public View getInfoContents(Marker marker) {
            return null;
        }
    });

    return false;
}

@Override
public boolean onClusterClick(Cluster<House> cluster) {
    mMap.moveCamera(CameraUpdateFactory.zoomIn());
    Toast.makeText(this, "onClusterClick", Toast.LENGTH_SHORT).show();
    return false;
}

@Override
public void onMapClick(LatLng latLng) {
    mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
}
}
