org.json.JSONException：。JSONObject的[ 「值」]不是JSONArray」

這是我的JSON數組org.json.JSONException：。JSONObject的[ 「值」]不是JSONArray」

[ 
    { 
    "type":"select", 
    "label":"Select", 
    "className":"form-control", 
    "name":"select-1497355331262", 
    "values":[ 
       { 
       "label":"Option 1", 
       "value":"option-1", 
       "selected":true 
       }, 
      { 
       "label":"Option 2", 
       "value":"option-2" 
      },

       "label":"Option 3", 
       "value":"option-3" 
      }

我能夠得到所有其他對象值我無法讀取值數組我已經寫了它的代碼，但它直接去catch塊打印錯誤消息「有一些錯誤」。請幫助。

爲什麼你的catch塊如此薄弱？爲什麼不打印「有一些錯誤」，爲什麼不像你在其他地方打印堆棧跟蹤一樣，'e.printStackTrace（）;'？這會給你更多有用的錯誤信息。 –

另外，爲什麼這麼多小的try/catch塊？ –

@HovercraftFullOfEels嘿檢查錯誤「org.json.JSONException：JSONObject [」values「]不是JSONArray。」 –

已解決...值不是一個數組，而是一個o bject ....所以這就是我所做的。有效。

try { 

       String j2 = obj.getString("values"); 
       JSONArray jContent = new JSONArray(j2); 
            for (int iterate = 0; iterate < jContent.length(); iterate++) { 
         JSONObject inner = jContent.getJSONObject(iterate); 
         String inner_label = (String) inner.get("label"); 

         System.out.println(inner_label); 

         String val = (String) inner.get("value"); 
         boolean sel; 
         try { 
          sel = (boolean) inner.get("selected"); 

         } catch (JSONException j) { 
          sel = false; 
         } 
         System.out.print(inner_label); 
         System.out.print(" " + val); 
         System.out.println(" " + sel); 

        }
