RecyclerView recyclerView = findViewById(R.id.recycler);
recyclerView.addOnItemTouchListener( 
    new RecyclerItemClickListener(context, recyclerView ,new RecyclerItemClickListener.OnItemClickListener() { 
      @Override public void onItemClick(View view, int position) {
        // do whatever 
      } 
 
      @Override public void onLongItemClick(View view, int position) {
        // do whatever
