如何在android中添加聚类标记的信息窗口？

Question

我想显示一个信息窗口，其中包含 Android 中所有标记的图像。我提到了这个Google Map Cluster Tutorial。

Answer 1

MyItem班级：

import com.google.android.gms.maps.model.LatLng;
import com.google.maps.android.clustering.ClusterItem;

public class MyItem implements ClusterItem {

    private LatLng mPosition;
    private String mLatitude = "";
    private String mStoreLogo = "";
    private String mLongitude = "";

    @Override
    public LatLng getPosition() {
        return mPosition;
    }

    public void setPosition(LatLng mPosition) {
        this.mPosition = mPosition;
    }

    public LatLng getmPosition() {
        return mPosition;
    }

    public void setmPosition(LatLng mPosition) {
        this.mPosition = mPosition;
    }

    public String getmLatitude() {
        return mLatitude;
    }

    public void setmLatitude(String mLatitude) {
        this.mLatitude = mLatitude;
    }

    public String getmLongitude() {
        return mLongitude;
    }

    public void setmLongitude(String mLongitude) {
        this.mLongitude = mLongitude;
    }

    public String getmStoreLogo() {
        return mStoreLogo;
    }

    public void setmStoreLogo(String mStoreLogo) {
        this.mStoreLogo = mStoreLogo;
    }

}

Map活动类：

public class Map extends FragmentActivity implements
        ClusterManager.OnClusterClickListener<MyItem>,
        ClusterManager.OnClusterInfoWindowClickListener<MyItem>,
        ClusterManager.OnClusterItemClickListener<MyItem>,
        ClusterManager.OnClusterItemInfoWindowClickListener<MyItem> {


    private ClusterManager<MyItem> mClusterManager;
    private Cluster<MyItem> clickedCluster;
    private MyItem clickedClusterItem;


    @SuppressWarnings("unchecked")
    @Override
    protected void onCreate(Bundle arg0) {
        super.onCreate(arg0);
        setContentView(R.layout.map_view);

        try {
          // Initializing Map from XML :
            GooglePlayServicesUtil.isGooglePlayServicesAvailable(Map.this);
            SupportMapFragment mapFrag = (SupportMapFragment) getSupportFragmentManager()
                    .findFragmentById(R.id.mMapView);

            mMapView = mapFrag.getMap();
            mMapView.setMapType(GoogleMap.MAP_TYPE_NORMAL);
            mMapView.getUiSettings().setZoomControlsEnabled(true);
            mMapView.getUiSettings().setCompassEnabled(true);
            mMapView.getUiSettings().setMyLocationButtonEnabled(true);
            mMapView.getUiSettings().setRotateGesturesEnabled(true);
            mMapView.getUiSettings().setScrollGesturesEnabled(true);
            mMapView.getUiSettings().setTiltGesturesEnabled(true);
            mMapView.getUiSettings().setZoomGesturesEnabled(true);
            mMapView.setMyLocationEnabled(true);

        } catch (Exception e) {
            mMapFrame.setVisibility(View.GONE);
            Utils.displayToast("Your device doesn't support Google Map", Map.this);
        }

   // Creating cluster manager object.

    mClusterManager = new ClusterManager<MyItem>(Map.this, mMapView);
        mMapView.setOnCameraChangeListener(mClusterManager);
        mClusterManager.setRenderer(new MyClusterRenderer(Map.this, mMapView,
                mClusterManager));

        mMapView.setOnInfoWindowClickListener(mClusterManager);
        mMapView.setInfoWindowAdapter(mClusterManager.getMarkerManager());
        mClusterManager.getClusterMarkerCollection().setOnInfoWindowAdapter(
                new MyCustomAdapterForClusters());
        mClusterManager.getMarkerCollection().setOnInfoWindowAdapter(
                new MyCustomAdapterForItems());
        mMapView.setOnMarkerClickListener(mClusterManager);
        mClusterManager.setOnClusterClickListener(this);
        mClusterManager.setOnClusterInfoWindowClickListener(this);
        mClusterManager.setOnClusterItemClickListener(this);
        mClusterManager.setOnClusterItemInfoWindowClickListener(this);

        mClusterManager
                .setOnClusterClickListener(new OnClusterClickListener<MyItem>() {

        mClusterManager

        // Adding Objects to the Cluster.    

        mClusterManager.addItem(mItemData);
                        mMapView.animateCamera(CameraUpdateFactory

代码是不言自明的。请将集群库和 google play services 库添加到您的构建路径中。如果您有任何疑问，请告诉我。
