[android-developers] Re: obtaining true dimensions of a View larger than the screen
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!

Beyond that, you will need to look at a specific class that is doing
scrolling.

Hello,
trying to implement a dynamic scrolview wrapping mechanism here. But
no matter what method I try from the View class they all return me the
view's part of height that is currently visible on screen. So if there
are 360 pixels available for a textview that has lots of text and is
currently using 400 pixels its getHeight() and many other related
methods always report 360.
Any way around this ? maybe getting to the View's Canvas ? How can I
go about that ?
Thank you!
