如何管理不在Android Google Map API中的群集中的单击标记? [英] How to manage click on marker which is not in Cluster in Android Google Map API?

问题描述

我无法为不在集群中的标记实现OnClickListener，即未使用以下方式添加标记:

I am having trouble implementing OnClickListener for Marker(s) which are not in Cluster, i.e. not added using:

 mClusterManager.addItem(markerCluster);

我将OnMarkerClickLister设置如下:

I have set OnMarkerClickLister as follows:

 mMap.setOnCameraIdleListener(mClusterManager);
 mMap.setOnMarkerClickListener(mClusterManager);

如果我只是使用:

 mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
        @Override
        public boolean onMarkerClick(Marker marker) {
            return false;
        }
    });

点击标记根本不起作用.

the click on markers is not working at all.

例如:我有这种情况:

两个绿点和一个大蓝点(数字6)是一个簇，但是红色标记不在簇中，因为我不希望它像其他标记一样被簇. 当我单击红色标记时，InfoWindow通常会显示，但是onMarkerClick以及OnClusterItemClickListener均不起作用.但是，当我单击群集"中的标记时，OnClusterItemClickListener可以工作.

Two green dots and big blue dot (with number 6) are one Cluster, but the red marker is not in Cluster as I don't want it to be Clustered like other markers. InfoWindow is normally showing when I click on red marker, but onMarkerClick doesn't work - as well as OnClusterItemClickListener. But OnClusterItemClickListener works when I click on markers which are in Cluster.

希望您了解我正在努力实现的目标.如果没有，请告诉我.

Hope you understand what I am trying to achieve. If not, please let me know.

更新后的答案

您在编辑中添加的图像清楚地说明了问题，非常感谢！

The image that you added in your edit explains the issue clearly, thanks for that!

为了同样解决此问题，我们需要以其他方式注册侦听器.即:通过将其注册到ClusterManager的MarkerManager，因为该类现在可以处理所有标记.我们还需要以不同的方式添加NormalMarkers，因此让我们逐步进行操作:

In order too solve this issue we need to register the listener differently. Namely: by registering it to the ClusterManager's MarkerManager as that class handles everything of the markers now. We also need to add the NormalMarkers a bit differently, so lets go through it step by step:

1)更新mMap的OnMarkerClickListener:

mMap.setOnMarkerClickListener(mClusterManager.getMarkerManager()); // Note the `MarkerManager` here

2)此MarkerManager保存所有集合.我们需要在此管理器上创建一个新集合，向该集合中添加应该与集群分开显示的NormalMarkers:

2) This MarkerManager holds all the collections. We need to create a new collection on this manager to which we will add the NormalMarkers that should be displayed apart from the clusters:

MarkerManager.Collection normalMarkersCollection = mClusterManager.getMarkerManager().newCollection();

3)添加标记的方式与之前类似，但是在我们创建的集合上使用了addMarker()方法.我们必须将MarkerOptions()对象传递给此对象:

3) Adding the markers is done similar to how this was before, but with using the addMarker() method on the collection that we created. We must pass a MarkerOptions() object to this:

// Create a normal marker
val markerOptions = MarkerOptions()
    .position(new LatLng(...))
    .title("My marker")
    .snippet("With description")

// Add it to the collection
normalMarkersCollection.addMarker(markerOptions)

4)最后但并非最不重要:我们要在其上放置OnClickListener:

4) Last but not least: we want the OnClickListener on it:

normalMarkersCollection.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener {
    public boolean onMarkerClick(marker: Marker) {
        // NORMAL MARKER CLICKED!
        return false;
    }
})

5)完成！现在，普通标记已像以前一样添加到地图上，但是具有有效的OnMarkerClickListener.

5) Done! Now the normal markers are added to the map just like before, but with a working OnMarkerClickListener.

(设置群集和群集项目的点击侦听器)

您应将Clicklistener添加到mClusterManager.使用ClusterManager时，在mMap上设置clicklistener无效.

You should add the clicklistener to the mClusterManager. Setting the clicklistener on the mMap does not work when using the ClusterManager.

因此，不要使用mMap.setOnMarkerClickListener，而是在集群管理器上设置ClusterItemClickListener:

Thus instead of using mMap.setOnMarkerClickListener, set the ClusterItemClickListener on the cluster manager:

mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<MyItem>() {
    @Override
    public boolean onClusterItemClick(MyItem item) {
        Log.d("cluster item","clicked");
        return true;
    }
});

此外，如果要捕获群集项的onclick，请使用ClusterClickListener:

Additionally, if you want to capture the onclick of the clustered item item, use the ClusterClickListener:

mClusterManager.setOnClusterClickListener(new ClusterManager.OnClusterClickListener<MyItem>() {
    @Override
    public boolean onClusterClick(Cluster<MyItem> cluster) {
        Log.d("cluster","clicked");
        return true;
    }
});
