I am switching fragment like this.

            FragmentManager fm = getFragmentManager();
            FragmentTransaction ft = fm.beginTransaction();

            FragmentName llf = new FragmentName();

            ft.replace(R.id.container_framelayout, llf);
            ft.addToBackStack(null);
            ft.commit();

I don't know if it's related to your problem but when you create a fragment from the same class multiple times, you shouldn't do FragmentName llf = new FragmentName();

You should do something like that :

FragmentName llf = FragmentName.newInstance();

And in FragmentName.class :

public static FragmentName newInstance(){
    return new FragmentName();
}

This way, a new Fragment will be made and you won't have any duplicated or "shared" fragment. More information are available here : Best practice for instantiating a new Android Fragment
