My problem is that I have a ScrollView within a fragment, and when this fragment is swapped into the container, the ScrollView is initially in the middle (it seems to be scrolled to a ListView I have inside of the ScrollView). I have tried using:
myScrollView.scrollTo(0, 0);
and
mainScrollView.fullScroll(ScrollView.FOCUS_UP);
but this doesn't do anything. When I include these in my fragment's onCreateView method, this line executes, but when the layout becomes visible on the phone it is still scrolled to the middle.
I'll include the XML code here:

There's a lot of stuff going on, so my worry is that some other view may be stealing focus or not allowing the ScrollView to scroll to top? The ScrollView I need scrolled to the top is @+id/pingScrollView. The included layout at the bottom is a chat bar.
Been stuck on this simple issue for days. I really appreciate any help!
Note: I have read a bunch of questions regarding my problem, such as this and this, but when I add any of that code (which seems like the correct, simplest solution) to my fragment, in either the onCreateView(), onStart(), or onResume() methods, nothing happens and the ScrollView remains scrolled to the middle.
