Fragment에서 viewpager 구현 문의드립니다.

Question

Fragment 에서 viewpager 를 만들고 있습니다.

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.test_viewpager, container, false);

        viewPager = (ViewPager) v.findViewById(R.id.pager);
        tabHost = (TabHost) v.findViewById(R.id.tabHost);
        hScrollVIew = (HorizontalScrollView) v.findViewById(R.id.h_scroll_view);

        initViewPager();

        initTabHost();


        return v;
    }

    private void initViewPager(){
        List<Fragment> listFragments = new ArrayList<Fragment>();

        listFragments.add(new Fragment11());  ////
        listFragments.add(new Fragment11());
        listFragments.add(new Fragment11());
        listFragments.add(new Fragment11());

        MyFragmentPagerAdapter myFragmentPagerAdapter = new MyFragmentPagerAdapter (getChildFragmentManager(), listFragments);

        viewPager.setAdapter(myFragmentPagerAdapter );
        viewPager.addOnPageChangeListener(this);

    }

......

public class MyFragmentPagerAdapter extends FragmentPagerAdapter {

        List<Fragment> listFragments;

        public MyFragmentPagerAdapter (FragmentManager fm, List<Fragment> listFragments) {
            super(fm);
            this.listFragments = listFragments;
        }

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

        }

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


.....

public class Fragment11 extends Fragment {

    private static Fragment11 fragment_;
    private String title;
    private int page;

    public static Fragment11 sharedInstance(int page) {
        if (fragment_ == null) {
            fragment_ = new Fragment11();
        }

//        Bundle args = new Bundle();
//        args.putInt("someInt", page);
//        args.putString("someTitle", title);
//        fragment_.setArguments(args);
        return fragment_;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
//        page = getArguments().getInt("someInt", 0);
//        title = getArguments().getString("someTitle");
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment1_layout, container, false);
        // 추후 webview로 변경
        TextView tv = (TextView) v.findViewById(R.id.textView1);

        return v;
    }

}

여기서 Fragment10 에 //// 친 부분을 변경하고 싶습니다.

listFragments.add(new Fragment11());  => listFragments.add(new Fragment11.sharedInstance(0));

이런식으로요..근데 이렇게 쓰면 에러가 나서요 ㅠㅠ

어떻게 구현해야하는지 조언좀 부탁드립니다.

그리고...Fragment10에서 viewPager로 4개 화면을 만들건데 모두 동일한 화면으로 webview 에서 보여주는 url 만 변경되는건데...

저렇게 같은 Fragment11 을 중복 add 하는 방법말곤 없을까요??
