firebaserecycleradapter sort/compare/reorder data before populate

问题

In my firebase database I have a collection of lat and long for each uid.

I use firebase recyler adapter data to list down my data to the recycler view.

FirebaseRecyclerAdapter<Model, ViewHolder> firebaseRecyclerAdapter =
            new FirebaseRecyclerAdapter<Model, ViewHolder>(Model.class, R.layout.row, ViewHolder.class, mRef) {

                @Override
                protected void populateViewHolder(final ViewHolder viewHolder, final Model model, int position) {

                    Double dist = distance(
                            myPosition.latitude,
                            myPosition.longitude,
                            Double.parseDouble(model.getLat()),
                            Double.parseDouble(model.getLon()));
                    Log.d("gs_distance", String.valueOf(dist));

                    viewHolder.setDetails(getApplicationContext(),
                            model.getLat(),
                            model.getLon(),
                            model.getGsname());
                }

The problem is I want to reorder/sort the data by nearest to farthest from my location, i can already fetch distance on how far each latlng is from my location. I dont know if there is a way to compare each latlng by their distance just before the data enters the populateViewHolder. Or maybe sort it after being inserted in the recyclerview? I really dont know.

static double distance(double fromLat, double fromLon, double toLat, double toLon) {
    Location loc1 = new Location("");
    loc1.setLatitude(fromLat);
    loc1.setLongitude(fromLon);

    Location loc2 = new Location("");
    loc2.setLatitude(toLat);
    loc2.setLongitude(toLon);

    float distanceInMeters = loc1.distanceTo(loc2);
    return distanceInMeters / 1000; //convert to km
}
