字符串无法在 Android 中转换为 JSONObject

Question

I'm implementing the JSONParsing but it getting the JSONException of org.json.JSONException: Value true at Status of type java.lang.String cannot be converted to JSONObject.Thanks in advanced.

Here is my Json String

{"Upd_Post_ActivityResult":{"ResponseItem":"103_20150900021028","Status":"true"}}

Here is the JSON Parsing

 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();
                            }
                        }

Here is log error

Answer 1

Try the below approach:

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

Status is not a JSONObject. So instead to getJSONObject("Status") you have to use String strStatusObj = json_Upd_Post_ActivityResult.getString("Status") ;

Answer 2

i have done few changes in your code , please check...

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());

                            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

Change this

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

to

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

Answer 4

请使用下面的，让我知道它是否有效

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