I have 2 fragments and both have`Scrollviews in them, I make a selection
from a ListView and that replaces the first fragment with the other
fragment that has the scrollview.
The problem is that when I try to replace the fragment with the new one I
get an error saying ScrollView can only contain one direct child which it
does, it has one RelativeLayout which holds all the content.
If i take the ScrollView out of the first fragments view I do not get the
error and the fragment gets replaced fine but I need the scrollview in the
first fragment.
What is causing this issue, does replacing a fragment not remove the view
fully?

this is how I replace the fragment
ft.replace(R.id.frameTwo, individual);
ft.addToBackStack(null).commit();
as you can see both scrollviews do have only a single child so I do not
understand the error
