How to reset viewpager content on Android?

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.
