滾動ListView導致應用程序崩潰

我有一個ListView我從SQLite數據庫填充。我的HTC Hero 2.1在我的ListView中有350行，一切正常。我將它安裝在Samsung Galaxy S 2.2上，並且我的ListView中有270行，每當我到達滾動列表的ListView的底部時，我的應用程序崩潰。滾動ListView導致應用程序崩潰

編輯：

下面是代碼：

@Override 
public View getView(int position, View convertView, ViewGroup parent){ 

    View v = convertView; 
    if (v == null) { 
     LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     v = vi.inflate(R.layout.row, null); 
    } 

    Item j = items.get(position); 

    if (j != null) { 
     TextView tvn = (TextView)v.findViewById(R.id.textViewName); 
     TextView tvnum = (TextView)v.findViewById(R.id.textViewNumber); 
     TextView tvid = (TextView)v.findViewById(R.id.textViewId); 
     TextView tvoper = (TextView)v.findViewById(R.id.textViewOperator); 

     if (tvn != null) { 
      tvn.setText(j.getname());       
     } 
     if(tvnum != null){ 
      tvnum.setText(j.getnumber()); 
     } 
     if (tvid != null) { 
      tvid.setText(j.getid());      
     } 
     if(tvoper != null){ 
      tvoper.setText(j.getoperator()); 

      if(j.getstatus().equals("0")){ 
       tvoper.setTextColor(Color.WHITE); 
      } 
      if(j.getstatus().equals("1")){ 
       tvoper.setTextColor(Color.GREEN); 
      } 
      if(j.getstatus().equals("2")){ 
       tvoper.setTextColor(Color.RED); 
      } 
     } 
    } 
}

必須有崩潰日誌。仔細檢查你的日誌。 – inazaruk

這一行：'at aec.phonebook.ListContacts $ ItemAdapter.getView（ListContacts.java:539）'可以爲null？調試你的應用程序並修復它，你會找到你的答案。 – Pedantic

@Chris不知道爲什麼在HTC英雄2.1工作正常？什麼會導致問題？我完全困惑 – user742362

可能是在代碼中可能出現的錯誤是「字符串數組大小」說你已經定義了。

例如：您創建的StringArray包含270個元素，但您定義的大小可能超過270個。會在剩餘的未初始化數組中創建空值的問題。

所以一定要確保ARRAYSIZE等於你LISTSIZE ..

希望它可以幫助
