Good hint. I was able to do
int h1 = computeVerticalScrollExtent();
int h3 = computeVerticalScrollRange();
if (h1 == h3)
{
//switch to linearlayout wrapper
}
inside a ScrollView wrapper. The above methods return the same thing
on a LinearLayout though (and probably also on regular Views), so at
first the trick needs assuming that the wrapped View needs a scrollbar
and then see if it really needs one.
Thanks!
