How to close a view by clicking on an empty space?

Question

Java

There is a Floating Button, when clicked, the cardview appears, and the fab disappears.

Code Example

fab = (FloatingActionButton) view.findViewById(R.id.fab);
        cardView = (CardView) view.findViewById(R.id.map_cardview);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                fab.hide();
                cardView.setVisibility(View.VISIBLE);
            }
        });

Is it possible to make the same cardview close when you click on an empty space in the fragment (this area is marked in red on the screenshot) and the fab reappears?

The easiest option is to make a FrameLayout for the entire area that you want to click on, and catch clicks on it.
