確切位置，顯示IndexOutOfBoundsException異常

我有一個列表視圖與一個TextView和一個複選框，其會從一個ArrayList從網絡service.It獲取數據填充工作fine.Now當我檢查在一個特定的如果我從上到下線性檢查，則列表中的複選框位置正在被抓取。 但是如果我在列表中選中任何複選框隨機複選框的確切位置並不牽強，它表明indexoutofbounds exception.I曾經嘗試都陣列適配器和底座adapter.please幫助我。確切位置，顯示IndexOutOfBoundsException異常

不要讓位置的變量最後，通過使用標籤cb_agency.setTag(ftpTable);然後使用compoundButton.getTag()獲取對象setOnCheckedChangeListener得到FtpTable的對象。

cb_agency.setTag(ftpTable); 
cb_agency.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
       @Override 
       public void onCheckedChanged(CompoundButton compoundButton, boolean b) { 
       FtpTable ftp = (FtpTable) compoundButton.getTag(); 
       //now you don't need position variable here. 
       Toast.makeText(mContext, "You have selected:" + ftp.getNewsAgency("newsAgency"), Toast.LENGTH_SHORT).show(); 
        } 
}

我已經嘗試了兩個適配器底座適配器和陣列適配器和都顯示相同的exception.I已編輯與底座適配器code.as據，如果我不做出最後的關鍵字是最後的關鍵字有關的問題不會在onCheckChanged中獲取，我該怎麼做？ – user8601021

我在回答中告訴過你，你可以使用標籤獲得物體，而不需要位置。 –

所以無論我正在使用onCheckChanged位置應該我cb_agency，getTag（）編輯它？u能請編輯我的代碼，並張貼了我該怎麼辦呢？ – user8601021
