Listview複選框數組索引出界限異常

Question

我有一個listview與複選框，每當用戶按下複選框我收到一些用戶信息（例如說facebook的個人資料ID） 並存儲在arraylist.Now是什麼問題是每當用戶滾動列表視圖一些其它的配置文件ID的也被添加或附加地eventhough除去它 不marked.so它提供

數組索引出界的異常

我試圖理清問題但我無法做到這一點，請provi給我一些解決方案。

這裏是我的完整列表視圖

public class MyComposeListItemAdapter extends ArrayAdapter { 

public Context mContext; 
int row;

* Initializes the ArrayList items to default value false, means no CheckBox is checked yet. 
* When you click on CheckBox. Set a check against Checked/Unchecked state and store that value in ArrayList. 
* Now set that position to CheckBox using setChecked() method.*/

請添加以下代碼，並再次運行它，並告訴我logcat的輸出：

[...] 
@Override 
     public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
      // TODO Auto-generated method stub 
      if(position >= getCount()) { 
       System.out.println("Error: position '"+position+"' is out of bounds in 'arrayList'"); 
       return; 
      } 
[...] 

防止重複列表中的條目：

if(!myList.contains(objectToInsert) { 
    myList.add(objectToInsert); 
}
