介绍我开发过程中用到的一种方法：我们知道当在布局中用到listview的时候，你没有进行优化处理的话，当条目多至如100条左右的时候，项目就会无响应自动挂断，所以我们可以采用在数据适配器中getView方法中复用covertView来减少找到布局的次数。实例代码如下：

 class MyAdapter extends BaseAdapter {

  @Override
  public int getCount() {
   // TODO Auto-generated method stub
   return mBlackNumberList.size();
  }

  @Override
  public Object getItem(int position) {
   // TODO Auto-generated method stub
   return mBlackNumberList.get(position);
  }

  @Override
  public long getItemId(int position) {
   // TODO Auto-generated method stub
   return position;
  }

  @Override
  public View getView(final int position, View covertView,
    ViewGroup parent) {
   View view = null;
   if (covertView == null) {

    view = View.inflate(getApplicationContext(),
      R.layout.listview_blacknumber_item, null);

   } else {
    view = covertView;

   }

   TextView tv_phone = (TextView) view
     .findViewById(R.id.tv_phonenumber);
   TextView tv_mode = (TextView) view.findViewById(R.id.tv_mode);
   ImageView iv_delete = (ImageView) view.findViewById(R.id.iv_delete);
