Why can't I interact with any views within my fragments? - xamarin

Question

^.^
I'm very new to xamarin.android and xamarin in general, and I'm finding the layout handling so much more trouble than I expected! I've finally managed to get fragments switching in and out in order to display different pages in my app, but now that that's working, the views/controls/elements such as buttons, scrollable layouts, text input, etc are not accepting input!
By that, I mean when testing, buttons do not recognise me tapping on them, my once-scrollable listview no longer scrolls when I swipe, etc.
This only applies to the views within the fragments, as the navigation drawer and other persistent default app buttons are all still fine.
I've looked for solutions everywhere but can't find anything that helps!
I'd greatly appreciate any advice/assistance, and if you require any additional information please just ask! ^.^
Thanks so much in advance! ^.^ <3
