org.json.JSONObject无法转换为JSONArray

从错误中可以明显看出，您正在尝试将Json Object转换为Json数组。那不应该。

这是读取您的JSON响应的代码。

String json = "Assuming that here is your JSON response"; try {    JSonObject parentObject = new JSonObject(json);    JSonObject userDetails = parentObject.getJSonObject("user_details");    //And then read attributes like      String name = userDetails.getString("user_name");     String phone = userDetails.getString("user_phone");    String id = userDetails.getString("re‌​f_id");} catch (JSonException e) {    // TODO Auto-generated catch block    e.printStackTrace();}

上面的代码用于

{"user_details":{"user_id":"1","user_name":"chand","user_phone":"9620085675","re‌​f_id":6386}}
