ScrollView Inside ScrollView

Question

I Know people from Google have asked us not to put Scrollable view inside another Scrollable view but is there any official statement from them directing us not to do so?

Answer 1

Is this close enough?

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.

UPDATE:

Since you may be forced to use a two dimensional scrollview, you may consider using this: Internet archive of blog.gorges.us/2010/06/android-two-dimensional-scrollview/

I haven't used this but it may be a reasonable approach.
