Answer 1

Maybe this will help someone

@Override
public void onChildAdded(@NonNull DataSnapshot dataSnapshot, @Nullable String s) {
    if (pingAdapter != null) {

        Ping ping = dataSnapshot.getValue(Ping.class);
        pingAdapter.pings.add(ping);
        recyclerView.smoothScrollToPosition(pingAdapter.getItemCount());

        pingAdapter.notifyDataSetChanged();
    }
}

recyclerView.smoothScrollToPosition(pingAdapter.pings.size());

is even faster
