openlayer3中地图重复怎么获取正确的坐标点

Posted 2023-05-08

对mapview添加OnMapClickListener事件监听，监听中有两个方法，publicvoidonMapClick(LatLngpoint)获取到的是空白地点的坐标；publicbooleanonMapPoiClick(MapPoipoi)获取到的是标记的建筑名称。具体代码如下：mMapView=(MapView)findViewById(R.id.bmapView);mBaiduMap=mMapView.getMap();mBaiduMap.setOnMapClickListener(newOnMapClickListener()/***地图单击事件回调函数*@parampoint点击的地理坐标*/publicvoidonMapClick(LatLngpoint)myLatitude=point.latitude;myLongitude=point.longitude;/***地图内Poi单击事件回调函数*@parampoi点击的poi信息*/@OverridepublicbooleanonMapPoiClick(MapPoiarg0)arg0.getName();//名称arg0.getPosition();//坐标returnfalse;); 参考技术A 参考： WebGIS(PostgreSQL+GeoServer+OpenLayers)之三 OpenLayers客户端数据显示(转) GIS开发记录(六)：OpenLayers显示Google离线map Openlayers 使用WFS添加到数据库一个点openlayer3中地图重复怎么获取正确的坐标点本回答被提问者采纳
