How to keep Buttons stuck at bottom while the rest above are occupied by scrollable layout?

The RecyclerView may contains lots of items (say > 80), that why I put it inside a ScrollView. And I want the Buttons to stay permanent on the bottom of the screen, that's why I use android:layout_alignParentBottom="true". But when I run in, the result is not what I expect. Turns out the Buttons are actually "floating" on top of the ScrollView, like this:
What I want is the LinearLayout containing the Buttons stuck at the buttom, and the rest above it are fully occupied by the ScrollView. How to fix this?

I recommended you use ConstraintLayout and avoid nested layout as much as you can. I have modified your code as little as possible just to fit your needs like below(replace margin/padding back to your desire):

Android Scrollview inside constraint layout is not working. How do i fix this?

Adding a scroll view inside a constraint layout is not working. Can anyone please help me to solve this issue? Here is the layout for your reference. Even after having one child linear layout inside a Scroll view is also not working. It overlaps out of the toolbar. They've also used constraint layout guidelines and it's a bit confusing. Kindly help me out.

Make your scroll view fill height and align bottom to parent bottom hopefully it will work.

Android Studio - I cannot see elements I made inside ScrollView, why?

Well, I made ScrollView and inside it, I put one LinearLayout. Inside that LinearLayout, I put multiple LinearLayouts and it does not show any error. Also, as you can see image, you can see their shape and that they are constrained. But I cannot see source/background of the ImageViews and TextViews neither within Android Studio nor when I buil app, why?

Try to use a NestedScrollView instead of the ScrollView ...that usually this is only required for CoordinatorLayout, but it eventually may also be the case within a ConstraintLayout.

Recycler view items auto wrapping inside scrollview

I am a newbie to android. I have Recyclerview implemented inside NestedScrollView. When I press next everything works fine, but when I return to the previous item it just wraps itself.
I have tried everything possible to make it work.
Following is the code.
For the Next & previous question, on pressing respective the following code executes
QuizAttemptFragment.xml.

Add this line android:fillViewport="true"
<ScrollView
android:fillViewport="true">
