My Android app has only one activity and all the fragments are added or replaced in one framelayout.
The issue is when I have two different viewpagers in the fragment backstack and the activity is recreated the second viewpager comes up as the first viewpager.
Below is how I add the fragments to the backstack in the order that they happen so 3 is the fragment that comes up after the activity is recreated.
- setupPlacesEventMainView(), this is a viewpager which uses a FragmentStatePagerAdapter.(shows up properly after activity is recreated)
- setupPlaceDetailViewPager, this is a viewpager which uses a FragmentStatePagerAdapter. (ISSUE: PlacesEventMainViewPager shows up here instead of PlaceDetailViewPager. The issue occurs even if I don't navigate into the EventSpecials)
- setupEventSpecials(), this is a listfragment. (shows up properly after activity is recreated)
Add PlacesEventMainViewPager to backstack
public void setupPlacesEventMainView()
{
clearBackStack();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
PlacesEventMainViewPager placesEventMainViewPager = new PlacesEventMainViewPager();
transaction.replace(R.id.fragment_container, placesEventMainViewPager, PlacesEventMainViewPager.class.getSimpleName());
transaction.commit();
}
Add PlaceDetailViewPager to backstack
public void setupPlaceDetailViewPager(Event event) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
PlaceDetailViewPager placeDetailViewPager = new PlaceDetailViewPager();
placeDetailViewPager.setEvent(event);
transaction.add(R.id.fragment_container, placeDetailViewPager,PlaceDetailViewPager.class.getSimpleName());
transaction.addToBackStack(PlaceDetailViewPager.class.getSimpleName());
transaction.commit();
}
Add SpecialsList to backstack
public void setupEventSpecials(Agenda[] agendas) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
SpecialsList specialsList = new SpecialsList();
specialsList.setAgendas(agendas);
transaction.add(R.id.fragment_container, specialsList,SpecialsList.class.getSimpleName());
transaction.addToBackStack(SpecialsList.class.getSimpleName());
transaction.commit();
}
What the fragments contain.
- PlacesEventMainViewPager contains 3 listfragments.
- PlaceDetailViewPager contains 2 listfragments
- SpecialsList is 1 listfragment.
I can reach the PlaceDetailViewPager fragment by clicking on one of the items in the PlacesEventMainViewPager fragment. I can reach the SpecialsList by clicking a button in the PlaceDetailViewPager fragment.
Please let me know if you need any more details. Thanks!
