wrap_content of LinearLayout which include FAB and text

I've added a LinearLayout which include a FAB and text to my XML. the height and width of the LinearLayout were set to 'wrap_content', but for some reason in the Design tab of the XML the box of the LinearLayout seems to have a larger and unnecessary height. How can I make the LinearLayout be at about the same height as the FAB and the text?

Thanks here is the XML code:

You had a large margin for the fab: android:layout_marginBottom="252dp" which must be removed or changed.
Use this:

Remove this

app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"

And it should work. What you're doing with those constraints is making it stretch to top and bottom.
