Question

我知道使用以下方法点击标记时可以避免使相机居中：

mGoogleMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
    @Override
    public boolean onMarkerClick(Marker marker) {
        marker.showInfoWindow();
        return true;
    }
});

但是，我遇到的问题是现在我想使用群集，当然我想在标记（实际上是项目或群集）时才能看到信息窗口。但我不知道在这些情况下如何调用类似showInfoWindow的东西。在这段代码中，如果我返回false，我会看到信息窗口，但是map是居中的。如果我返回true，则map不居中，但不显示info窗口：

    mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<HotspotMarker>() {
        @Override
        public boolean onClusterItemClick(HotspotMarker item) {
            Log.e(LOG_TAG, "---OnClusterItemClick");
            return false;
        }
    });

    mClusterManager.setOnClusterItemInfoWindowClickListener(new ClusterManager.OnClusterItemInfoWindowClickListener<HotspotMarker>() {
        @Override
        public void onClusterItemInfoWindowClick(HotspotMarker hotspotMarker) {
            Log.e(LOG_TAG, "---onClusterItemInfoWindowClick");
            HotspotDetailActivity.hotspot = hotspotMarker.getHotspot();
            Intent intent = new Intent(getActivity(), HotspotDetailActivity.class);
            startActivity(intent);
        }
    });

    mClusterManager.setOnClusterClickListener(new ClusterManager.OnClusterClickListener<HotspotMarker>() {
        @Override
        public boolean onClusterClick(Cluster<HotspotMarker> cluster) {
            Log.e(LOG_TAG, "---OnClusterClickListener");
            return false;
        }
    });

    mClusterManager.setOnClusterInfoWindowClickListener(new ClusterManager.OnClusterInfoWindowClickListener<HotspotMarker>() {
        @Override
        public void onClusterInfoWindowClick(Cluster<HotspotMarker> cluster) {
            Log.e(LOG_TAG, "---onClusterInfoWindowClick");
            ArrayList<HotspotMarker> markers = new ArrayList<>(cluster.getItems());
            ClusterListActivity.markers = markers;
            Intent detailHotspot = new Intent(getActivity(), ClusterListActivity.class);
            startActivity(detailHotspot);
        }
    });

当我使用群集并同时显示信息窗口时，您是否知道如何避免使地图居中？提前谢谢。

编辑：使用@skywall建议，我发现使用自定义渲染器的方法更好：

mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<HotspotMarker>() {
            @Override
            public boolean onClusterItemClick(HotspotMarker item) {
                Marker marker=mClusteringRenderer.getMarker(item);
                marker.showInfoWindow();
                return true;
            }
        });

    mClusterManager.setOnClusterItemInfoWindowClickListener(new ClusterManager.OnClusterItemInfoWindowClickListener<HotspotMarker>() {
        @Override
        public void onClusterItemInfoWindowClick(HotspotMarker hotspotMarker) {
            HotspotDetailActivity.hotspot = hotspotMarker.getHotspot();
            Intent intent = new Intent(getActivity(), HotspotDetailActivity.class);
            startActivity(intent);
        }
    });

    mClusterManager.setOnClusterClickListener(new ClusterManager.OnClusterClickListener<HotspotMarker>() {
        @Override
        public boolean onClusterClick(Cluster<HotspotMarker> cluster) {
            Marker marker=mClusteringRenderer.getMarker(cluster);
            marker.showInfoWindow();
            return true;
        }
    });

    mClusterManager.setOnClusterInfoWindowClickListener(new ClusterManager.OnClusterInfoWindowClickListener<HotspotMarker>() {
        @Override
        public void onClusterInfoWindowClick(Cluster<HotspotMarker> cluster) {
            ArrayList<HotspotMarker> markers = new ArrayList<>(cluster.getItems());
            ClusterListActivity.markers = markers;
            Intent detailHotspot = new Intent(getActivity(), ClusterListActivity.class);
            startActivity(detailHotspot);
        }
    });

Answer 1

return true

的

setOnClusterItemClickListener

Answer 2

请勿直接通过GoogleMap.OnMarkerClickListener()设置mGoogleMap.setOnMarkerClickListener()的新实例。

相反，将mClusterManager设置为点击处理程序，如下所示：

mGoogleMap.setOnMarkerClickListener(mClusterManager);

并处理点击次数：

mClusterManager.setOnClusterItemClickListener();
mClusterManager.setOnClusterClickListener();

首次点击时默认显示InfoWindow。

编辑：我现在明白了问题所在。我创造的并不是很漂亮的解决方案，但它确实有效。以这种方式修改您的点击监听器：

mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<MyClusterItem>() {
        @Override
        public boolean onClusterItemClick(MyClusterItem item) {
            for (Marker marker : mClusterManager.getMarkerCollection().getMarkers()) {
                if (marker.getPosition().latitude == item.getPosition().latitude && 
                    marker.getPosition().longitude == item.getPosition().longitude) {
                    marker.showInfoWindow();
                }
            }
            return true;
        }
    });

Answer 3

我无法禁用，但我可以在下方移动地图（在我的情况下需要，因为某些抽屉覆盖了屏幕的上半部分）。

public View getInfoContents(Marker marker) {
    .....
    bottomBarButton1.postDelayed(new Runnable() {
        @Override
        public void run() {
            final CameraPosition cp=map.getCameraPosition();
            final Point mappoint = map.getProjection().toScreenLocation(new LatLng(cp.target.latitude, cp.target.longitude));
            mappoint.set(mappoint.x, (int) (dispHeight*0.1f));
            map.animateCamera(CameraUpdateFactory.newLatLng(map.getProjection().fromScreenLocation(mappoint)), null);
        }
    },500);
    .....

}

如何在使用群集时禁用android地图标记点击自动中心？
