Finally, add a constructor for GameViewHolder that takes a View as its one parameter. Set mTitleLabel using the ID R.id.

public class GameAdapter extends RecyclerView.Adapter<GameAdapter.GameViewHolder> {

    private Game[] mGames;

    public GameAdapter(Game[] games) {
        mGames = games;
    }

    @Override
    public GameViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return null;
    }

    @Override
    public void onBindViewHolder(GameViewHolder holder, int position) {
        // code omitted for brevity
    }
  class GameViewHolder extends RecyclerView.ViewHolder {
    public TextView mTitleLabel;
    public GameViewHolder(View) {
        mTitleLabel = View.findViewById(R.id.titleLabel);
    }
  }

    @Override
    public int getItemCount() {
        return 0;
    }

    /* Add your code here */
}
