Control the visibility and elevation of the referenced views Added in 1.1

This class controls the visibility of a set of referenced widgets. Widgets are referenced by being added to a comma separated list of ids, e.g.:

         <androidx.constraintlayout.widget.Group
             android:id="@+id/group"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:visibility="visible"
             app:constraint_referenced_ids="button4,button9" />
    

The visibility of the group will be applied to the referenced widgets. It's a convenient way to easily hide/show a set of widgets without having to maintain this set programmatically.

Multiple groups

Multiple groups can reference the same widgets -- in that case, the XML declaration order will define the final visibility state (the group declared last will have the last word).
