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:

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