ArcGIS for Android 10.2.9（9）：Json与Geometry的相互转换

一、Geometry转换成Json数据

  Point point = new Point(113, 23);
  String json = GeometryEngine.geometryToJson(SpatialReference.create(SpatialReference.WKID_WGS84), point);
  Log.e("xyh", "onCreate: " + json);

输出结果：

 {"x":113.0,"y":23.0,"spatialReference":{"wkid":4326}}

二.json转化为Geometry

  try {
            String jsonStr = "{\"x\":113.0,\"y\":23.0,\"spatialReference\":{\"wkid\":4326}}";
            JsonFactory jsonFactory = new JsonFactory();
            JsonParser jsonParser = jsonFactory.createJsonParser(jsonStr);
            MapGeometry mapGeometry = GeometryEngine.jsonToGeometry(jsonParser);
            Point point2 = (Point) mapGeometry.getGeometry();

            Log.e("xyh", "onCreate: " + point2.getX() + "==" + point2.getY());
        } catch (IOException e) {
            e.printStackTrace();
        }

输出结果:

113.0==23.0
