Android arcgis 坐标转经纬度

down vote

If you want to convert map point to lat/long you just need to follow this

Point mapPoint = mMapView.toMapPoint(point.getX(), point.getY());//Here point is your MotionEvent pointSpatialReference spacRef = SpatialReference.create(4326);//4326 is for Geographic coordinate systems (GCSs) Point ltLn = (Point)GeometryEngine.project(mapPoint,mMapView.getSpatialReference(), spacRef ); //mMapView is your current mapview object

ltLn.getY() will give latitude and ltLn.getX() will give longitude

这是esri.SpatialReference函数中的属性，wkid即well-known ID（定义好的） ，4326代表地理坐标系中的GCS_WGS_1984 ，这个可以在arcgis的帮助中查看
