Process: com.example.alfattah.absensiproject, PID: 14194
java.lang.IllegalArgumentException: You have 3 tabs.
at eu.long1.spacetablayout.SpaceTabLayout.initialize(SpaceTabLayout.java:266)

and this my code :

public class DashboardFragment extends Fragment {

public DashboardFragment() {
// Required empty public constructor
}

SpaceTabLayout tabLayout;
List fragmentList = new ArrayList<>();
CheckinFragment checkinFragment = new CheckinFragment();
MapsFragment mapsFragment = new MapsFragment();
CheckOutFragment checkOutFragment = new CheckOutFragment();
ViewPager dashboardViewpager;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_dashboard, container, false);
dashboardViewpager = view.findViewById(R.id.viewPagerdashboard);
tabLayout = view.findViewById(R.id.spaceTabLayout);

fragmentList.add(checkinFragment);
fragmentList.add(mapsFragment);
fragmentList.add(checkOutFragment);

tabLayout.initialize(dashboardViewpager, getActivity().getSupportFragmentManager(), fragmentList, savedInstanceState);

return view;
}

@Override
public void onSaveInstanceState(@NonNull Bundle outState) {
tabLayout.saveState(outState);
super.onSaveInstanceState(outState);

}

@Override
public void onStart() {
super.onStart();

}
}

Research direction

Start at SpaceTabLayout.java:266 and inspect how initialize handles the three fragments supplied by DashboardFragment. Reproduce the flow by opening another fragment and returning to the tab layout, then verify that initialization completes without the “You have 3 tabs” exception.
