Only use this adapter with managed RealmCollection, for un-managed lists you can just use the BaseRecyclerViewAdapter #5623

Here my adapter:

public abstract class PreviewSortRealmAdapter extends RealmRecyclerViewAdapter {

    public PreviewSortRealmAdapter(Context context, @Nullable OrderedRealmCollection data, boolean autoUpdate) {
        super(data, true);
        setHasStableIds(true);
        this.context = context;
    }
}

Here how I create data:

public static OrderedRealmCollection<PointOfSaleListItem> getPointOfSaleListItem(Realm realm, Bundle filter, String sortByFieldName) {
        OrderedRealmCollection<PointOfSaleListItem> pointOfSaleListItemsCollection = new RealmList<>();
        RealmResults<Merchant> merchantsRealmResults = getMerchants(realm, filter, sortByFieldName);
        for (Merchant merchant : merchantsRealmResults) {
            PointOfSaleListItem pointOfSaleListItem = new PointOfSaleListItem();
            pointOfSaleListItem.setMerchantImageUrl(merchant.getPreview().getFormats().getReference().getUrl());
            RealmList<PointOfSale> pointOfSaleRealmList = merchant.getPointsOfSale();
            for (PointOfSale pointOfSale : pointOfSaleRealmList) {
                pointOfSaleListItem.setPointOfSale(pointOfSale);
                pointOfSaleListItemsCollection.add(pointOfSaleListItem);
            }
        }
        return pointOfSaleListItemsCollection;
    }

But I get error:

new RealmList<>() creates an unmanaged collection, you can only use RealmRecyclerViewAdapter with RealmResults, or RealmList obtained from a managed RealmObject.

alexei-28 commented 6 years ago

Is it possible to convert RealmList(unmanaged collection) to RealmResults? If not than I have only one solution. Use standard RecyclerView.Adapter Is I'm right?

Zhuinden commented 6 years ago

If you can't express your result set with RealmQuery, then yes
