1.在adapter中串id以及点击事件

myAdapterViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(context,ShangActivity.class);
                intent.putExtra("id",mlsslist.get(i).getCommodityId());
                context.startActivity(intent);
            }
        });
