Scrollview scrolls up-and-over other content when scrolling

Question

When layin out this form, I want a header the size of its content, footer the size of the content, and a middle that expands to take up the rest. Easy in XAML/UWP. But in Xamarin Forms when the ScrollView content has data it floats and overlays the top and bottom. Also when I drag/scroll the ScrollView it can go to the top of the screen. How to dock the scrollview properly so I have a scrolling middle region? Thx...
