I've got a card view having a maps fragment followed by a button inside a ScrollView. In portrait view, the fragment displays with proper height but doesn't scroll and so the button doesn't even appear. In landscape view, it does scroll but the fragment displays as a thin strip. Here is the code. I even tried to keep the fragment outside the card view, but even that didn't help, having the same results.
