Android arcgis 坐标转经纬度

Point mapPoint = mMapView.toMapPoint(point.getX(), point.getY());
//Here point is your MotionEvent point
SpatialReference 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()

ltLn.getX()
