Android - 解析了不完整的JSON響應

-2

我使用Volley JSON請求從Web服務中解析JSON。Android - 解析了不完整的JSON響應

這是它的樣子：

     } 
    ] 
}

但是，我得到了一個不完整的JSON響應。只有前兩個結果對象被成功解析。這裏是解析json的方法：

private void loadItemList() { 
    mRequestQueue = Volley.newRequestQueue(getActivity()); 
    pd = ProgressDialog.show(getActivity(), null, "Loading..."); 

    String url = Constants.LATEST_ITEM_LIST; 

    JsonObjectRequest jr = new JsonObjectRequest(Request.Method.GET, url, 
      null, new Response.Listener<JSONObject>() { 
       @Override 
       public void onResponse(JSONObject response) { 
        Log.i(TAG, response.toString()); 
        parseJSON(response); 
        va.notifyDataSetChanged(); 
        pd.dismiss(); 
       } 
      }, new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError error) { 
        pd.dismiss(); 
        Log.i(TAG, error.getMessage()); 

        errorMsg = VolleyErrorHelper.getMessage(error, 
          getActivity()); 

        Toast.makeText(getActivity(), errorMsg, 
          Toast.LENGTH_LONG).show(); 
       } 
      }); 

    mRequestQueue.add(jr); 
} 

private void parseJSON(JSONObject json) { 
    if (json != null) { 
     try { 
      JSONArray items = json.getJSONArray("results"); 
      for (int i = 0; i < json.length(); i++) { 
       JSONObject itemlist = items.getJSONObject(i); 

       ItemListModel ilm = new ItemListModel(); 
       ilm.setCategory(itemlist.optString(Constants.TAG_CATEGORY_NAME)); 
       ilm.setItem_id(itemlist.optString(Constants.TAG_ITEM_ID)); 
       ilm.setName(itemlist.optString(Constants.TAG_ITEM_NAME)); 
       ilm.setPrice(itemlist.optString(Constants.TAG_ITEM_PRICE)); 
       ilm.setUser_id(itemlist.optString(Constants.TAG_USER_ID)); 

       JSONObject thumb = itemlist.getJSONObject(Constants.TAG_ITEM_THUMBNAIL); 
       ilm.setThumbnail(thumb.optString(Constants.TAG_ITEM_THUMB)); 

       arrItemList.add(ilm); 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } else { 
     Log.d("Item list: ", "null"); 
    } 
}

上面的邏輯有什麼問題嗎？

它總是更好地使用GSON或JACKSON lib中JSON解析，您使用的是你爲什麼要使用JSON解析手動舊方法有效的lib凌空？創建POJO並開始使用GSON庫！ –

在這裏，你已經解析您的JSON數組一樣

JSONArray items = json.getJSONArray("results");

因此，在你的循環，而不是使用JSON對象，你必須使用你的項目 JsonArray。因此，您可以訪問其中包含的其他數據。

因此改變從

for (int i = 0; i < json.length(); i++)

到

for (int i = 0; i < items .length(); i++)

哈哈，小錯。謝謝 – AimanB

@AimanB很樂意幫助你！ – Piyush

因爲的JSONObject爲json.length();你獲得長度試試這個..

你的循環，你需要從從items.length();JSONArray得到長度不JSONObject的

JSONArray items = json.getJSONArray("results"); 
for (int i = 0; i < items.length(); i++) {

在你的For循環你已經定義了你的數組大小json對象不是你的JsonArray可能這就是爲什麼它沒有給出prope r結果。

將您的items JsonArray的大小放在您的for循環中，如items.length()。

試試如下：

JSONArray items = json.getJSONArray("results"); 
     for (int i = 0; i < items.length(); i++) {
