Android : PagerSlidingTab with listFragment Android

I'm using this library to make sliding tabs but i want to open one Listfragment instead of a simple fragment but i don't know how to modify my pageradapter

MyPagerAdapter :

class MyPagerAdapter extends FragmentPagerAdapter {

public MyPagerAdapter(FragmentManager fm) {
    super(fm);
}
@Override
public CharSequence getPageTitle(int position) {
    return (position == 0)? "Scannez " : "Historique" ;
}
@Override
public int getCount() {
    return 2;
}
@Override
public Fragment getItem(int position) {

    return (position == 0)? new f1() : new f2() ;
}
