在撥打webservices時卡住

Question

我需要在列表視圖中顯示一些記錄，但是當我撥打服務時，它會讓我在adapter.so中發生錯誤，您能告訴我如何糾正它嗎？我在USERNAME中有Arrayindexoutofbound。我也有檢查的主要活動，但也有在all.this代碼沒有問題的previosly工作好。不過現在它提升問題....

Answer 1

你確定活動名稱和用戶名具有相同的大小？看來，Activityname.length> Username.length

編輯：在您的構造函數中添加此功能來檢查數組的大小

Log.d("TEST", "Activityname size = " + Activityname.length); 
    Log.d("TEST", "UserName size  = " + UserName.length); 
    Log.d("TEST", "PlayedDate size = " + PlayedDate.length); 
    Log.d("TEST", "UserComment size = " + UserComment.length); 
    Log.d("TEST", "Score size  = " + Score.length); 

EDIT2：別那麼肯定！

根據Android documentation，如果集合的大小大於參數數組，則collection.toArray（Object []）方法將創建一個新數組。因此，str_arr_ActivityName和str_arr_UserName的大小可能與ActivityName.size（）不同。

Answer 2

它告訴你，你正試圖訪問一個數組超出其範圍。

具體來說，這裏：UserName[position]。如TeddyBearFr所述，此處的位置大於或等於UserName.length。

你必須弄清楚，你有這個問題。

另外，你真的需要清理你的代碼位：

• 注意你如何命名變量，這是不是Java友好。看看一些guidelines。
• 創建一個對象：Log將封裝了所有這些變量：scoreId，activityName，userName等等......然後，你的適配器將只讀的Log秒的陣列。
• 當你點擊按鈕Ok時應該在後臺線程中完成，所以請嘗試使用AsyncTask。
