How to reset viewpager content on Android?

Question

Please tell me how to reset the content of ViewPager on android. I tried to call adapter.notifyDataSetChanged() but the adapter doesn't call getItem(position) when I scroll the view. It always returns old child views.

Update: This is my Fragment View. When I reset viewPager data, It used loaded Fragment views. It's just start at the onCreateView instead of Constructor.

public class ResultView extends Fragment {
//Declare properties

     //Constructor 
public ResultView(Province province, Calendar calendar) {
    Log.d("xskt", "ResultView constructor");
    this.province = province;
    this.calendar = (Calendar) calendar.clone();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    Log.d("xskt", "ResultView onCreateView");
    View view = inflater.inflate(R.layout.resultview, null);

    //do some thing

    return view;
}

Thanks.

I have changed to use FragmentStatePagerAdapter instead of FragmentPagerAdapter, the problem is resolved. Hope this helps.

I think the best solution to reload fragments in another fragment is :

@Override
public void onPause() {
    super.onResume();
    List<Fragment> fragments = getFragmentManager().getFragments();
    if (fragments != null) {
        FragmentTransaction fragmentTransaction  = getFragmentManager().beginTransaction();
        for (Fragment fragment : fragments) {
            if (fragment instanceof Fragment) {
                fragmentTransaction.remove(fragment);
            }
        }
        fragmentTransaction.commitNowAllowingStateLoss();
    }
}

Check for your use case whether commitNowAllowingStateLoss or commitAllowingStateLoss is necessary.
