How to implement Item Click on RecyclerView (Easiest Approach)

MainActivity.java

    /* Changes start from here... */
    public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener
    {
        // each data item is just a string in this case
        public TextView mTextView;
        public ViewHolder(View itemView) {
            super(itemView);
            itemView.setOnClickListener(this);
            mTextView = itemView.findViewById(R.id.textView);
        }
        
        @Override
        public void onClick(View view) 
        {           
            // get the position on recyclerview.
            int pos = getLayoutPosition();

            SingleItemClick(pos);    // click on recyclerview item.
        }
    }
    
    /* Changes End Here */

@nvinai It's a custom function which takes integer pos and passes to other variables. Useful if you have many lines of code in onClick, else you can write your code just here.
