Logcat顯示我的Android應用程序運行後IndexOutOfBound異常

我的應用程序的logcat顯示一些IndexOutOfBound異常。在這裏我試圖創建一個條形圖在android中使用achartengine庫。並且我得到x軸而從消費它的Web服務y軸值，我下面的消耗網絡service.Can任何一個讓我知道我犯我對我的項目是什麼錯誤SOAP的方法？Logcat顯示我的Android應用程序運行後IndexOutOfBound異常

建議請！..

感謝您的寶貴時間！..

你能告訴你的Manifest.xml – VenomVendor

檢查這條線'com.example.barchart_test.Chart_MainActivity $ 1.onClick（Chart_MainActivity.java:43）' –

的'克etTMSChart'方法返回一個空列表（可能是try-catch塊中的一個異常），然後嘗試獲取元素。 – Luksprog

你確定你正從服務器端的東西嗎？在從中獲取元素之前，您不檢查結果列表大小。至於我在這個問題上弦樂器 in.putExtra（「gotonextpageX」，result.get（0））; in.putExtra（「gotonextpageY」，result.get（1））;

我相信我收到從服務器成功 – Rohith

咦x軸和y軸的值？無論你在哪裏使用x和y，都不要將它們添加到ArrayList中。返回的列表只是空的。另外**你在主線程**上進行網絡調用。您不應該這樣做 - 如果持續時間過長，您的用戶將看到ANR錯誤消息！ –

出界異常的添加數組索引到你的主要活動代碼

    int tablesCount = root.getPropertyCount(); 

    for (int i = 0; i < tablesCount; i++)

     SoapObject table = (SoapObject) root.getProperty(i); 
     int propertyCount = table.getPropertyCount();
