Seems that context is null. No idea why (perhaps you made a mistake during the refactor) but maybe try this to test if it works?

Intent intent=new Intent(holder.itemView.context,BilActivity.class);
intent.putExtra("id",id);
holder.itemView.context.startActivity(intent); //You might have to cast this to an activity.
