android - Horizo​​ntalScrollView 与 ListView——文档错误？

Question

Horizo​​ntalScrollView 的文档如下:

You should never use a HorizontalScrollView with a ListView, since ListView takes care of its own scrolling. Most importantly, doing this defeats all of the important optimizations in ListView for dealing with large lists, since it effectively forces the ListView to display its entire list of items to fill up the infinite container supplied by HorizontalScrollView.

这里的推理似乎适用于(垂直滚动的)ScrollView，因为 ListView 也垂直滚动。但是 ScrollView 没有任何这样的警告。 Google 是否将此警告放在了错误的类别中，还是我不明白什么？

看起来确实是一个错误:http://code.google.com/p/android/issues/detail?id=2781
