Detect click on RecyclerView outside of items

I have a RecyclerView with 2 items that don\'t fill the whole screen. How can I detect that the user clicked on the empty part of the RecyclerView (meaning clicked directly on t

You just need to set a TouchListener on the RecyclerView like shown above :

categoryTable.setAdapter(new CatgoriesAdapter(categories.getWrappedList()));
    categoryTable.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_DOWN
                    && categoryTable.findChildViewUnder(event.getX(), event.getY()) == null)
            {
                // Touch outside items here, you do whatever you want  
                HideCategoryMenu();
            }
            return false;
        }
    });
