Scroll view does not scroll - Android Studio-CodePudding

I can't make a ScrollView properly scrolling. I can scroll through the page but the scrollView itself not showing and it always cut off the content on the bottom. The buttons portion is being cut off in portrait orientation, and not scrolling at all in the landscape orientation.
Here is my XML code:
