Android : How to manage fragments in a single Activity?

I wonder whether I can manage fragments like Activity.
I implemented tab function with fragment(in fact, I couldn't get result from startActivityForResult using TabHost), and I wanna call each fragment when tab menu selected saving its previous view like using intent with FLAG_ACTIVITY_REORDER_TO_FRONT. Whenever I replace fragment, program always create new fragment.
Any idea?
Thanks in advance.

ps. I tried to use savedInstanceState, but Bundle only provides putInt, putString, putBundle, etc. Is it possible to save view or other objects?

@PatrickBoos Here is my code. After declare FragmentManager fm and FragmentTransaction ft,

AFragment fragment = AFragment.getInstance();
if (!fragment.isAdded())
    ft.replace(res, fragment, tag);
ft.commit();

and AFragment.newInstance() is implemented as,

AFragment mThis;
public static AFragment getInstance() {
    if (mThis == null)
        mThis = new AFragment();
    return mThis;
}

Try using something similar to the code below to reuse a fragment

ContactListFragment contactListFragment = 
     (ContactListFragment)getFragmentManager().findFragmentByTag("ContactList");
if(contactListFragment == null){
contactListFragment = new ContactListFragment();
}
ft.replace(R.id.fragment_container, contactListFragment,"ContactList";
ft.commit();
