Firebase Data Desc Sorting in Android

Question

I am storing data in Firebase storage.

Object Comment with attribute timestamp. When I push data from device to Firebase I\'m populating

Answer 1

The @Monet_z_Polski approach, based on

@Override
public T getItem(int position) {
  return super.getItem(getCount() - (position + 1));
}

does have a weird effect on not update FirebaseRecyclerView automatically (PopulateViewHolder is not triggered in realtime changes). So, the best option is use a negative key to index the data.
