touchGuardDrawable doesn't work in fragment

[albe3188]

I have a main activity on which fragments are displayed.

I use a library, SpaceTabLayout that needs two elements in the main_activity.xml:

• View pager (match_parent and match_parent)
• Space tab layuot (bar at the bottom which is wrap_content and wrap_content but still occupies the whole layout as if it were match_parent).

When I insert the FabSpeedDial (match_parent), everything works correctly apart from the touchGuardDrawable function that does not obscure the fragment.
