Is there any way to remove the listener without its name or remove all listener?

Question

As the title, is there any way to remove all listeners without it's name or some thing like that?

This is what I am doing:

ref.removeEventListener(valueEventName);

why did my question is marked duplicate ? please read the question carefully, I dont ask about how to remove. I want to know if there is a way to remove Listener without its name. — Trần Quốc Trung, Mar 25 '19 at 13:45
Hey Tran. To remove an event listener from a query, you must have a reference to the listener. See https://firebase.google.com/docs/reference/android/com/google/firebase/database/Query.html#removeEventListener(com.google.firebase.database.ChildEventListener) — Frank van Puffelen, Mar 25 '19 at 14:35
thanks @FrankvanPuffelen , I already knew that. I just confuse a little bit about remove Listener without its name. But I think it is not posible. — Trần Quốc Trung, Mar 25 '19 at 15:31

To be able to remove a listener from a query/location in Android, you need to have a reference to that listener. See the reference docs.

There is no method in the Android SDK to remove all listeners from a query/location.
