Add Fragment Tag and Retrive it

Question

I am trying to call Fragment Function from my activity. I am following This Answer for same. Currently My Fragment code is like below in my HomeActivity.

   class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

        @Override
        public Fragment getItem(int position) {
            return mFragmentList.get(position);
        }

        @Override
        public int getCount() {
            return mFragmentList.size();
        }

        void addFragment(Fragment fragment, String title) {
            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);
        }
    }

I want add Tag in this Fragment but does not know how can I do it. I have total three fragment in which I need add Tag so I can retrieve it later. Let me know if someone can help me for achieve this.

Thanks
