A temporary solution to use RecyclerView with Realm (based on RealmBaseAdapter). Note: make sure you create an io.realm package, and put this class there.

RealmBaseRecyclerViewAdapter.java

package io.realm;

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;

public abstract class RealmBaseRecyclerViewAdapter<T extends RealmObject, M extends RecyclerView.ViewHolder> extends RecyclerView.Adapter<M> {

    protected LayoutInflater inflater;
    protected RealmResults<T> realmResults;
    protected Context context;
    private RealmChangeListener listener;

    public RealmBaseRecyclerViewAdapter(Context context, RealmResults<T> realmResults, boolean automaticUpdate) {
        if (context == null) {
            throw new IllegalArgumentException("Context cannot be null");
        }
        this.context = context;
        this.realmResults = realmResults;
        this.inflater = LayoutInflater.from(context);
        this.listener = (!automaticUpdate) ? null : new RealmChangeListener() {
            @Override
            public void onChange() {
                notifyDataSetChanged();
            }
        };

        if (listener != null && realmResults != null) {
            realmResults.getRealm().addChangeListener(listener);
        }
    }

    @Override
    public int getItemCount() {
        if (realmResults == null) {
            return 0;
        }
        return realmResults.size();
    }

    public T getItem(int i) {
        if (realmResults == null) {
            return null;
        }
        return realmResults.get(i);
    }

    /**
     * Returns the current ID for an item. Note that item IDs are not stable so you cannot rely on
     * the item ID being the same after {@link #notifyDataSetChanged()} or
     * {@link #updateRealmResults(RealmResults)} has been called.
     *
     * @param i Index of item in the adapter
     * @return Current item ID.
     */
    @Override
    public long getItemId(int i) {
        // TODO: find better solution once we have unique IDs
        return i;
    }

    /**
     * Update the RealmResults associated to the Adapter. Useful when the query has been changed.
     * If the query does not change you might consider using the automaticUpdate feature
     *
     * @param queryResults the new RealmResults coming from the new query.
     */
    public void updateRealmResults(RealmResults<T> queryResults) {
        if (listener != null) {
            // Making sure that Adapter is refreshed correctly if new RealmResults come from another Realm
            if (this.realmResults != null) {
                this.realmResults.getRealm().removeChangeListener(listener);
            }
            if (queryResults != null) {
                queryResults.getRealm().addChangeListener(listener);
            }
        }

        this.realmResults = queryResults;
        notifyDataSetChanged();
    }

}

Note: make sure you put it in io.realm package.

I'm sorry if this is a noob question, but how do I put this file in the io.realm package? Changing package isn't possible because the corresponding file path needs to be the same too. What am I missing?

Update: I simply created a new package "io.realm". Is this what you meant?

@Saketme Sorry, completely missed your message. If it's still relevant, what you did is exactly what I meant 👍
