这是一个基于this answer 的简化和略微修改的解决方案。请注意，链接的答案为标记和集群实现了一个信息窗口。
此解决方案只为标记实现 InfoWindows。
这类似于您如何为没有聚类的普通标记实现自定义 InfoWindowAdapter，但额外要求您保留对当前选定项目的引用，以便您可以从它的 MyItem 实例中获取标题和片段，因为标记不会像通常那样存储标题和片段。
请注意，由于所有数据都存储在 MyItem 引用中，因此扩展功能以在信息窗口中为每个标记显示任意数量的数据类型要容易得多。
首先是 MyItem.java，其中包括 Title 和 Snippet 的额外字段：
public class MyItem implements ClusterItem {
private final LatLng mPosition;
private final String mTitle;
private final String mSnippet;
public MyItem(double lat, double lng, String t, String s) {
mPosition = new LatLng(lat, lng);
mTitle = t;
mSnippet = s;
}
@Override
public LatLng getPosition() {
return mPosition;
}
public String getTitle(){
return mTitle;
}
public String getSnippet(){
return mSnippet;
}
}
这里是完整的 Activity 类，其中包括支持 InfoWindows 的所有功能，以支持使用集群库添加的每个标记：
编辑：在 InfoWindow 上添加了对处理点击事件的支持，使 Activity 实现 OnClusterItemInfoWindowClickListener 并添加了 onClusterItemInfoWindowClick 回调。
public class MapsActivity extends AppCompatActivity
implements ClusterManager.OnClusterItemInfoWindowClickListener<MyItem> {
private ClusterManager<MyItem> mClusterManager;
private MyItem clickedClusterItem;
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
setUpMapIfNeeded();
}
@Override
protected void onResume() {
super.onResume();
setUpMapIfNeeded();
}
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null) {
setUpMap();
}
}
}
private void setUpMap() {
mMap.getUiSettings().setMapToolbarEnabled(true);
mMap.getUiSettings().setZoomControlsEnabled(true);
mMap.setMyLocationEnabled(true);
mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
mClusterManager = new ClusterManager<>(this, mMap);
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(37.779977,-122.413742), 10));
mMap.setOnCameraChangeListener(mClusterManager);
mMap.setOnMarkerClickListener(mClusterManager);
mMap.setInfoWindowAdapter(mClusterManager.getMarkerManager());
mMap.setOnInfoWindowClickListener(mClusterManager); //added
mClusterManager.setOnClusterItemInfoWindowClickListener(this); //added
mClusterManager
.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<MyItem>() {
@Override
public boolean onClusterItemClick(MyItem item) {
clickedClusterItem = item;
return false;
}
});
addItems();
mClusterManager.getMarkerCollection().setOnInfoWindowAdapter(
new MyCustomAdapterForItems());
}
private void addItems() {
double latitude = 37.779977;
double longitude = -122.413742;
for (int i = 0; i < 10; i++) {
double offset = i / 60d;
double lat = latitude + offset;
double lng = longitude + offset;
MyItem offsetItem = new MyItem(lat, lng, "title " + i+1, "snippet " + i+1);
mClusterManager.addItem(offsetItem);
}
}
//added with edit
@Override
public void onClusterItemInfoWindowClick(MyItem myItem) {
//Cluster item InfoWindow clicked, set title as action
Intent i = new Intent(this, OtherActivity.class);
i.setAction(myItem.getTitle());
startActivity(i);
//You may want to do different things for each InfoWindow:
if (myItem.getTitle().equals("some title")){
//do something specific to this InfoWindow....
}
}
public class MyCustomAdapterForItems implements GoogleMap.InfoWindowAdapter {
private final View myContentsView;
MyCustomAdapterForItems() {
myContentsView = getLayoutInflater().inflate(
R.layout.info_window, null);
}
@Override
public View getInfoWindow(Marker marker) {
TextView tvTitle = ((TextView) myContentsView
.findViewById(R.id.txtTitle));
TextView tvSnippet = ((TextView) myContentsView
.findViewById(R.id.txtSnippet));
tvTitle.setText(clickedClusterItem.getTitle());
tvSnippet.setText(clickedClusterItem.getSnippet());
return myContentsView;
}
@Override
public View getInfoContents(Marker marker) {
return null;
}
}
}
info_window.xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="20dp"
android:orientation="vertical"
android:background="#000000">
<TextView
android:id="@+id/txtTitle"
android:textColor="#D3649F"
android:textStyle="bold"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/txtSnippet"
android:textColor="#D3649F"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
结果：
首次发布：
缩小，开始聚类：
再次缩小，更多聚类：
然后，放大并单击单个标记：
然后点击另一个标记：
编辑：为了在自定义信息窗口周围显示“语音气泡”，请使用 getInfoContents() 而不是 getInfoWindow()：
public class MyCustomAdapterForItems implements GoogleMap.InfoWindowAdapter {
private final View myContentsView;
MyCustomAdapterForItems() {
myContentsView = getLayoutInflater().inflate(
R.layout.info_window, null);
}
@Override
public View getInfoWindow(Marker marker) {
return null;
}
@Override
public View getInfoContents(Marker marker) {
TextView tvTitle = ((TextView) myContentsView
.findViewById(R.id.txtTitle));
TextView tvSnippet = ((TextView) myContentsView
.findViewById(R.id.txtSnippet));
tvTitle.setText(clickedClusterItem.getTitle());
tvSnippet.setText(clickedClusterItem.getSnippet());
return myContentsView;
}
}
结果：
