在android textView中怎么实现文字的纵向的滚动

似乎textview没有纵向滚动属性,反正我没试出来,同楼上,建议用animation实现该效果,不过用不了那么多,2个就可以了,不知道楼主要在屏幕顶部实现还是其他位置? 刚才没事做了一个简单的例子,如果在顶部不用这么麻烦,写的特繁琐,把animation的各种属性都写上了,这样楼主可以根据不同的需要做修改.

下面是xml.两个button主要是为了和顶部留有距离,

android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
