RecyclerView onClick for multiple buttons and handling from Activity

Question

I'm using RecyclerView with CardView and inside the CardView have 2 buttons. Now, have implemented the onClick events by implementing View.OnClickListener by the ViewHolder static class and overriding the event (its working )like

    @Override
    public void onClick(View v) {

        if (v.getId() == mClassBtn.getId()){

        }
        else if (v.getId() == mDaysBtn.getId()){

        }
     }

Looking for a solution/pattern to handle the Click in the Activity class like

adapter = new ItemsListAdapter(getActivity(), data, new CustomItemClickListener() { 

    @override
    public void onItemClick(View v, int position) {

       Log.d(TAG, "clicked position:" + position);
       // which button clicked and separate action for each button
    } 
});
// CustomItemClickListener -- interface in the adapter class which holds the click event .

The above code working fine and able to log the Clicks but not able to differentiate which button has clicked.

Appreciate any help

here is the best way to achieve that:--

this is how i have implemented

public class FollowersDetailsAdapter extends RecyclerView.Adapter<FollowersDetailsAdapter.MyViewHolder> {

    private List<GetUserFollowDetailsResponseData> followersList;
    Context context;
    public FollowersDetailsAdapterListener onClickListener;


    public class MyViewHolder extends RecyclerView.ViewHolder {
        public TextView rv_tv_follower_name, rv_tv_follower_desig;
        public CircleImageView rv_iv_follower_image;
        RelativeLayout rv_rel_layout_followers, rel_layout_followers;
        LikeButton rv_iv_follower_icon;

        public MyViewHolder(View view) {
            super(view);
            rv_rel_layout_followers = (RelativeLayout) view.findViewById(R.id.rv_rel_layout_followers);
            rel_layout_followers = (RelativeLayout) view.findViewById(R.id.rel_layout_followers);
            rv_iv_follower_image = (CircleImageView) view.findViewById(R.id.rv_iv_follower_image);
            rv_tv_follower_name = (TextView) view.findViewById(R.id.rv_tv_follower_name);
            rv_tv_follower_desig = (TextView) view.findViewById(R.id.rv_tv_follower_desig);
            rv_iv_follower_icon = (LikeButton) view.findViewById(R.id.rv_iv_follower_icon);
            rel_layout_followers.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    onClickListener.iconTextViewOnClick(v, getAdapterPosition());
                }
            });
        }

    }

    public FollowersDetailsAdapter(List<GetUserFollowDetailsResponseData> FollowersList, FollowersDetailsAdapterListener listener) {
        this.followersList = FollowersList;
        this.onClickListener = listener;

    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.followers_list_row, parent, false);

        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, final int position) {
        if (followersList.get(position).getImage() != null && !followersList.get(position).getImage().trim().equalsIgnoreCase("")) {
            Picasso.with(context)

                    .load(followersList.get(position).getImage())
                    .resize(200, 200).into(holder.rv_iv_follower_image);
        }

        holder.rv_tv_follower_name.setText(followersList.get(position).getName());
        holder.rv_tv_follower_desig.setText(followersList.get(position).getDescription());
        if (followersList.get(holder.getAdapterPosition()).getID() == Integer.parseInt(ApplicationPreference.getUserId())) {
            holder.rv_iv_follower_icon.setVisibility(View.GONE);
        } else {
            holder.rv_iv_follower_icon.setVisibility(View.VISIBLE);
            if (followersList.get(position).getIsFollowing() == 0) {
                holder.rv_iv_follower_icon.setLiked(false);
            } else if (followersList.get(position).getIsFollowing() == 1) {
                holder.rv_iv_follower_icon.setLiked(true);
            }


        }
        holder.rv_iv_follower_icon.setOnLikeListener(new OnLikeListener() {
            @Override
            public void liked(LikeButton likeButton) {

                onClickListener.iconImageViewOnClick(likeButton, position);
            }

            @Override
            public void unLiked(LikeButton likeButton) {
                onClickListener.iconImageUnFollowOnClick(likeButton, position);
            }
        });

    }

    public interface FollowersDetailsAdapterListener {

        void iconTextViewOnClick(View v, int position);

        void iconImageViewOnClick(View v, int position);

        void iconImageUnFollowOnClick(View v, int position);
    }

    @Override
    public int getItemCount() {
        return followersList.size();
    }
}

and in your activity where you initialize the adapter--

 followersDetailsAdapter = new FollowersDetailsAdapter(followersList, new FollowersDetailsAdapter.FollowersDetailsAdapterListener() {
            @Override
            public void iconTextViewOnClick(View v, int position) {
                gotoUserProfile(followersList.get(position).getID());

            }

            @Override
            public void iconImageViewOnClick(View v, int position) {

                followUserProfile(followersList.get(position).getID(),1);
            }

            @Override
            public void iconImageUnFollowOnClick(View v, int position){

                followUserProfile(followersList.get(position).getID(),0);
            }
        });
