不专心时，Android隐藏FAB菜单

Question

I have a Floating Action Button with a custom menu of mini Floating Action Buttons, that appears upon click on the main Floating Action Button.
The mini FABs are in a LinearLayout.

I want that after opening the FAB menu, when the user clicks elsewhere, the menu disappears. However, I haven't been able to find how to do this.
What listener do I need for this?

Any help?

Thanks.

You are most likely interested in a custom FloatingActionButton.Behavior :

https://developer.android.com/reference/android/support/design/widget/FloatingActionButton.Behavior.html

Otherwise you can simply set the Visibility of the respective controls to Gone based on a OnTouchListener that checks if you are touching outside the FAB .
