android - popBackStack() 并在 Adapter 中传递参数

Question

我想在 RecyclerView 中单击行时返回到上一个 fragment 。那么如何在我的适配器中调用该函数呢？

 @Override
    public void onBindViewHolder(final CountryViewHolder holder, int position) {
        String country = countries.get(position);
        holder.tvCountrySelection.setText(country);
        holder.tvCountrySelection.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                holder.tvCountrySelection.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ic_tick_17, 0);
                //I want to run popBackStack() here and send String country to previous fragment.
            }
        });
    }
