在Android中無法將字符串轉換爲JSONObject

Question

我正在實現JSONParsing，但它獲取的是org.json.JSONException的JSONException：值true時，狀態類型java.lang.String無法在高級中轉換爲JSONObject.Thanks。

這裏是我的JSON字符串

{ 「Upd_Post_ActivityResult」：{ 「的ResponseItem」： 「103_20150900021028」， 「狀態」： 「真正的」}}

這裏是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(); 
          } 
         } 

這裏是日誌錯誤

Answer 1

試試下面的方法：

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

狀態不是一個JSONObject。所以，而不是獲得JSONObject（「狀態」），你必須使用 String strStatusObj = json_Upd_Post_ActivityResult.getString("Status");

Answer 2

常E本

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

到

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

Answer 3

請使用下面，讓我知道無論是工作或沒有

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

Answer 4

我已經在你的代碼做一些修改，請檢查。 ..

嘗試 { JSONObject js onObj = 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(); 
         } 
        }
