我在文件中有这个JSON字符串。我正在使用函数连接到json文件，这是我的解析，我正在获得纬度和逻辑。我接下来该怎么做？

JSONObject data = new JSONObject(convertStreamToString(jsonString)).getJSONObject("data");
                // Get the query value'

                JSONArray Acolumns = data.getJSONArray("columns");
                JSONArray Arows = data.getJSONArray("rows");



                for (int i = 0; i < Arows.length(); i++) {
                    JSONArray rec = Arows.getJSONArray(i);
                    //stringJsonResult += "\n rows:" + rec;
                    int latitude = rec.getInt(3);
                    int longitude = rec.getInt(4);

                    //stringJsonResult += "\n  latitude + longitude;
                }

                jsonString.close();
                //JsonResult.setText("\n" + stringJsonResult);

感谢您的帮助，Michal。

编辑::好的，谢谢你ryanm的帮助，你的应用程序工作;）是否可以制作具有纬度和经度的JSON数组，例如：{points：{[lat1，long1]，[lat2，long2]}并添加它到谷歌地图？有什么不同的想法来解决我的问题？

Answer 1

查看this app以获取指针。它下载一个json字符串，解析它，并在地图视图上显示lat / lon点。

从json文件获取经度和经度，并将点插入谷歌地图 - Android
