Question

我正在实现JSONParsing，但它获得了org.json.JSONException的JSONException：在类型为java.lang.String的Status处的值true无法转换为JSONObject.Thanks in advanced。

这是我的Json String

{＆＃34; Upd_Post_ActivityResult＆＃34; {＆＃34;的ResponseItem＆＃34;：＆＃34; 103_20150900021028＆＃34;＆＃34;状态＆＃34;：＆＃34;真＆＃ 34;}}

这是JSON解析

 if (result != null) {
                            try
                            {
                                JSONObject jsonObj = new JSONObject(result);
                                String jsonResult = jsonObj.toString().trim();
                                Log.e("jsonResult ", " = " + jsonResult);

                                JSONObject json_Upd_Post_ActivityResult = jsonObj.getJSONObject("Upd_Post_ActivityResult");
                                Log.e("getAllActivity_List ", " = " + json_Upd_Post_ActivityResult.toString());

                                JSONObject jobj1 = json_Upd_Post_ActivityResult.getJSONObject("Status");
                                String strStatusObj = jobj1.toString();
                                Log.e("strStatusObj "," = " + strStatusObj);

                                if(strStatusObj.equals("true"))
                                {
                                    Log.e("StartMark Url Uploaded ", "Succesfully !!!!!");
                                    Log.e("Status ", "True");
                                    int imagesArray = imgItemArray.size();
                                    Log.e("imagesArray "," = "+imagesArray);


                                }
                                else
                                {
                                    Log.e("Status ","False");
                                }
                            }
                            catch (JSONException je)
                            {
                                je.printStackTrace();
                            }
                        }

这是日志错误

Answer 1

尝试以下方法：

JSONObject jobj1 = json_Upd_Post_ActivityResult.getJSONObject("Status");
String strStatusObj = jobj1.toString();

状态不是JSONObject。因此，您需要使用getJSONObject（＆＃34; Status＆＃34;） String strStatusObj = json_Upd_Post_ActivityResult.getString("Status");

Answer 2

我对您的代码进行了一些更改，请检查...

试 { JSONObject jsonObj = new JSONObject（result）; String jsonResult = jsonObj.toString（）。trim（）; Log.e（“jsonResult”，“=”+ jsonResult）;

                            JSONObject json_Upd_Post_ActivityResult = jsonObj.getJSONObject("Upd_Post_ActivityResult");
                            Log.e("getAllActivity_List ", " = " + json_Upd_Post_ActivityResult.toString());

                            String strStatusObj = json_Upd_Post_ActivityResult.getString("Status");
                            Log.e("strStatusObj "," = " + strStatusObj);
                            if(strStatusObj.equals("true"))
                            {
                                Log.e("StartMark Url Uploaded ", "Succesfully !!!!!");
                                Log.e("Status ", "True");
                                int imagesArray = imgItemArray.size();
                                Log.e("imagesArray "," = "+imagesArray);


                            }
                            else
                            {
                                Log.e("Status ","False");
                            }
                        }
                        catch (JSONException je)
                        {
                            je.printStackTrace();
                        }
                    }

Answer 3

更改此

JSONObject jobj1 = json_Upd_Post_ActivityResult.getJSONObject("Status");

到

String strStatusObj = json_Upd_Post_ActivityResult.getString("Status");

Answer 4

请使用以下内容告诉我它是否正常工作

String str=json_Upd_Post_ActivityResult.getString("Status");

在Android中，无法将字符串转换为JSONObject
