我正在使用RealmRecyclerViewAdapter。我的問題是實(shí)施Filterable不起作用。這是代碼： private class AirportAdapter extends RealmRecyclerViewAdapter<AirportR,RecyclerView.ViewHolder> implements Filterable{    Context context;    OrderedRealmCollection<AirportR>listAirports;    public AirportAdapter(Context activity, OrderedRealmCollection<AirportR>airports)    {        super(activity,airports, true);        this.context = activity;        this.listAirports = airports;    }    @Override    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)    {        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.airport_show, parent,false);        AirportClass holder = new AirportClass(view);        return holder;    }    @Override    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position)    {       AirportR airportR = listAirports.get(position);        AirportClass mHolder = (AirportClass)holder;        mHolder.country.setText(airportR.getIsoCountry());        mHolder.name.setText(airportR.getName());    }    public Filter getFilter()    {       AirportFilter filter = new AirportFilter(this, listAirports);        return filter;    }    private class AirportFilter extends Filter    {        private final AirportAdapter adapter;        OrderedRealmCollection<AirportR>originalList;        OrderedRealmCollection<AirportR>filteredList;        private AirportFilter(AirportAdapter adapter, OrderedRealmCollection<AirportR> originalList)        {            super();            this.adapter = adapter;            this.originalList = originalList;        }而我給了錯(cuò)誤：java.lang.UnsupportedOperationException: This method is not supported by RealmResults.                  at io.realm.RealmResults.addAll(RealmResults.java:710)                  at com.example.matteo.downloadairports.fragment.ListAirportFragment$AirportAdapter$AirportFilter.publishResults過濾并更新適配器后如何保存結(jié)果？謝謝
