リスト項目を再利用していません。これが、リストが「ぎくしゃく」し始めている理由です。
この問題には、ListView アイテムを再利用するという概念を示す多くの回答があります。 このように
一般に、getViewメソッド内で、convertViewが null かどうかを確認します。そうである場合は、ビューを膨らませます。null でない場合は、表示するアイテムを挿入するだけです。これにより、リストビューが途切れる問題が解決するはずです。

Please use for existing layout in BaseAdpter as below
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 ();
}
this may helps you
