**[This](https://stackoverflow.com/questions/49383687/how-can-i-retrieve-data-from-firebase-to-my-adapter/49384849)** is a recommended way in which you can retrieve data from a Firebase Realtime database and display it in a `RecyclerView` using `FirebaseRecyclerAdapter`. — Alex Mamo, Nov 18 '18 at 11:45

Try as follows

DatabaseReference mDatabase;

mDatabase = FirebaseDatabase.getInstance().getReference();
DatabaseReference mRef = mDatabase.getReference();


mDatabase.child("users").addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {

        for (DataSnapshot postSnapshot: snapshot.getChildren()) {
            String name = postSnapshot.getValue();
            //do what you want
    }

    @Override
    public void onCancelled(DatabaseError error) {
        // Failed to read value
        Log.w(TAG, "Failed to read value.", error.toException());
    }
});
