您没有重复使用列表项。这就是列表开始“结巴”的原因。
关于这个问题有很多答案显示了重用 ListView 项目的概念。 像这个
一般来说：在您的getView方法中，检查是否convertView为空。如果是，请夸大你的观点。如果它不为空，只需插入要显示的项目。这应该可以解决您口吃的列表视图问题。

请用于 BaseAdapter 中的现有布局，如下所示
ViewHolder holder = null;
if ( convertView == null )
{
/* There is no view at this position, we create a new one.
In this case by inflating an xml layout */
convertView = mInflater.inflate(R.layout.listview_item, null);
holder = new ViewHolder();
holder.toggleOk = (ToggleButton) convertView.findViewById( R.id.togOk );
convertView.setTag (holder);
}
else
{
/* We recycle a View that already exists */
holder = (ViewHolder) convertView.getTag ();
}
这可能会帮助你
