Как обновить список ListView получаемый с бд Firebase?

Получаю вот так:

   //Это в onCreate
   final AccAdapter adapter = new AccAdapter();
   binding.myList.setAdapter(adapter);

    Query myQuery = myRef;
    myQuery.addChildEventListener(new ChildEventListener() {
        @Override
        public void onChildAdded(DataSnapshot snapshot, String previousChildName) {
            Accounts accounts = snapshot.getValue(Accounts.class);
            adapter.add(accounts);
        }

        @Override
        public void onChildChanged(DataSnapshot snapshot, String previousChildName) {

        }

        @Override
        public void onChildRemoved(DataSnapshot snapshot) {

        }

        @Override
        public void onChildMoved(DataSnapshot snapshot, String previousChildName) {

        }

        @Override
        public void onCancelled(DatabaseError error) {

        }
    }); 
    //Конец onCreate

    private class AccAdapter extends ArrayAdapter<Accounts> {
    AccAdapter() {
        super(MainActivity.this, R.layout.list_design);
    }

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        final View view = getLayoutInflater().inflate(R.layout.list_design, null);
        final Accounts accounts = getItem(position);
        ((TextView) view.findViewById(R.id.name)).setText(accounts.text_one);
        ((TextView) view.findViewById(R.id.price)).setText(accounts.text_two);
        return view;
    }
}
