Android - Dynamic Fragment problems on orientation change

Question

I\'m having a problem with dynamic fragment . If I\'m not change orientation , it work fine . When I change orientation , I click on ListView item . It\'s not change textview .<

Answer 1

I found the problems are : When the system destroys and re-creates an activity because of a run-time configuration change, the activity automatically re-instantiates existing fragments.

This isn’t a problem for “static” fragments declared in the activity’s layout.

But for “dynamic” fragments, i need to test for this situation to prevent creating a second instance of my fragment.

I check the Bundle argument passed to my activity’s onCreate() is null.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_dynamic);

    if(savedInstanceState == null)
    {
        FragmentManager fragmentManager = getFragmentManager();
        FragmentTransaction transaction = fragmentManager.beginTransaction();
        ListContentFragment listContentFragment = new ListContentFragment();
        DetailsContentFragment detailsContentFragment = new DetailsContentFragment();
        transaction.add(R.id.listContainer, listContentFragment,"listContent");
        transaction.add(R.id.detailsContainer, detailsContentFragment,"detailsContent");
        transaction.commit();
    }

}

And it work fine . I think is helpful for someone have same problems .
