constraint layout inside scrollview white space at bottom?

Question

I am using Scroll View inside constraint layout and it generate white space at the bottom XML code Here

Answer 1

Just add android:fillViewport="true" in the ScrollView works for me.

Answer 2

The issue for me was that in the constraint view, I connected on of the elements to the bottom of the screen. Do not connect any of the UI elements to the bottom. Only use the left, right, and top sides of the screen to set the constraints for all the elements. This solved my issue
