      }
      holder.tv.setText(strList.get(position));
      holder.cb.setChecked(boolList.get(position));
      if(visflag)

  {
    menu.add(0, 0, 0, "批量处理");
    menu.add(0, 1, 0, "确定删除");
    return super.onCreateOptionsMenu(menu);
  }
  @Override
  public boolean onOptionsItemSelected(MenuItem item)
  {
    switch(item.getItemId())
    {
      case 0: // 批量处理
 {
   if(visflag)
   {
     visflag = false;
     for(int i=0; i0)
   {
     if(visflag)
     {
for(int location=0; location

还有list_item.xml
