    you already have int position, just make it final and then you may use it inside onClick

    @Override
public void onBindViewHolder(@NonNull ViewHolder holder, final int position) {
    ...
    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(context, myMovieDataList.getMovieName(),  Toast.LENGTH_SHORT).show(); 
            Intent intent = new Intent(v.getContext(), MainActivity2.class);
            intent.putExtra("position", position);
            // would be better to pass item id or name, much better approach
            intent.putExtra("itemId", myMovieDataList.getMovieId());
            v.getContext().startActivity(intent);

        }
    });
}

    Answer by @snachman is perfectly right. But, it is not preferred by google. Use the method given below.

    1. Create a new interface with name RecyclerViewItemClickListener.java
    2. Add method void onClick(); to it;
    3. Add that to the constructor of the adapter.
    4. After adding the constructor, add it to your activity by implementing the interface
    5. Add it in the activity by new RecyclerViewItemClickListener
    6. Now in the activity, add the code to start the activity.
      Hope it helps 😀
