    public ViewHolder(View itemView) {
        super(itemView);
        m_premiumText = (TextView) itemView.findViewById(R.id.tv_premiun_deals);
        m_getDealText = (TextView) itemView.findViewById(R.id.tv_get_deals);

        m_getDealText.setOnClickListener(new View.OnClickListener() {

    mContext = getActivity();
    main = inflater.inflate(R.layout.reward_premium_deals, container, false);
    findViewById();
    initControls();
    return main;
}


public void findViewById() {
    m_premiumList = (RecyclerView) main.findViewById(R.id.premium_list);
    m_layoutManager = new LinearLayoutManager(mContext);
    m_premiumList.setLayoutManager(m_layoutManager);

}

public void initControls() {
    premiumNames = getResources().getStringArray(R.array.premium_deals_title);
    m_premiumDealsAdapter = new CPremiumDealsAdapter(mContext, premiumNames);
    m_premiumList.setAdapter(m_premiumDealsAdapter);

There are million resources already regarding this. If you have specific question regarding the implementation, create that. — Nabin, Apr 26 '17 at 04:20

in these cases you must use an listener or callback and send it to your recycler view adapter through constructor.

firstly create a new interface to use as the callback. then implement that interface in your fragment and then send your fragment (this) as the listener to your adapter. then you can call that action from your recycler view instance.

From this Reference, I have implemented in recycler view item in my activity class not in fragment.

Interface Class:

public interface RecyclerViewClickListener {
    void onClick(View view, int position);
    void onLongClick(View view, int position);
}

RecyclerViewTouchListener Class:

public class RecyclerViewTouchListener implements RecyclerView.OnItemTouchListener {
private GestureDetector gestureDetector;
private RecyclerViewClickListener recyclerViewClickListener;

public RecyclerViewTouchListener(Context context, final RecyclerView recyclerView, final RecyclerViewClickListener recyclerViewClickListener1) {
    recyclerViewClickListener = recyclerViewClickListener1;
    gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
        @Override
        public boolean onSingleTapUp(MotionEvent e) {
            return true;
        }

        @Override
        public void onLongPress(MotionEvent e) {
            View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
            if (child != null && recyclerViewClickListener1 != null){
                recyclerViewClickListener.onLongClick(child, recyclerView.getChildLayoutPosition(child));
            }
        }
    });
}

@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
    View child = rv.findChildViewUnder(e.getX(), e.getY());
    if (child != null && recyclerViewClickListener != null && gestureDetector.onTouchEvent(e)){
        recyclerViewClickListener.onClick(child, rv.getChildLayoutPosition(child));
    }
    return false;
}

@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {

}

@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

}
}

Now, inside fragment or activity class where you have to setup you recycler view activties:

recyclerView.setAdapter(your_adapter_class_object);
recyclerView.addOnItemTouchListener(new RecyclerViewTouchListener(this, recyclerView, new RecyclerViewClickListener() {
    @Override
    public void onClick(View view, int position) {
        Loge("Item","Click");
    }

    @Override
    public void onLongClick(View view, int position) {
        Loge("Item","Long Click");
    }
}));
