I have one FragmentActivity, with one ViewPager and one FragmentStatePagerAdapter. When i change the screen orientation screen on viewPager, i can see the viewPager but not the fragments. I test all post on Stackoverflow.
FragmentStatePagerAdapter
public class PageAdapter extends FragmentStatePagerAdapter{
private static final String[] CONTENT = new String[] { "All", "Installed"};
List<Application> applicationList;
public PageAdapter(FragmentManager fm,List<Application> applicationList) {
super(fm);
this.applicationList = applicationList;
}
@Override
public Fragment getItem(int position) {
return ListAppFragment.newInstance(CONTENT[position % CONTENT.length],applicationList);
}
@Override
public CharSequence getPageTitle(int position) {
return CONTENT[position % CONTENT.length].toUpperCase();
}
@Override
public int getCount() {return CONTENT.length;}
}
Fragment
public class ListAppFragment extends Fragment {
public static final String APPS_LIST = "APPS_LIST";
public static final String VIEW_TYPE = "VIEW_TYPE";
private GoogleCardAdapter mGoogleCardAdapter;
private ListView listView;
private Utils utils;
String typeView;
public static ListAppFragment newInstance(String typeView,List<Application> applicationList) {
ListAppFragment listAppFragment = new ListAppFragment();
Bundle bundle = new Bundle();
bundle.putString(VIEW_TYPE, typeView);
bundle.putParcelableArrayList(APPS_LIST, (ArrayList<Application>) applicationList);
listAppFragment.setArguments(bundle);
return listAppFragment;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
utils = new Utils((Context)getActivity().getApplicationContext());
typeView = getArguments().getString(VIEW_TYPE);
View v = inflater.inflate(R.layout.list_app_fragment, container, false);
listView = (ListView)v.findViewById(R.id.activity_googlecards_listview);
ArrayList<Application> applicationList = getArguments().getParcelableArrayList(APPS_LIST);
setApplicationList(applicationList, typeView);
return v;
}
private void setApplicationList(List<Application> applicationList,String typeView) {
if(typeView=="Installed"){
applicationList = utils.getAppsAlreadyInstalled(applicationList);
}
mGoogleCardAdapter = new GoogleCardAdapter(getActivity().getApplicationContext(),applicationList);
AlphaInAnimationAdapter alphaInAnimationAdapter = new AlphaInAnimationAdapter(new AlphaInAnimationAdapter(mGoogleCardAdapter));
alphaInAnimationAdapter.setInitialDelayMillis(300);
alphaInAnimationAdapter.setAbsListView(listView);
listView.setAdapter(alphaInAnimationAdapter);
}
}
Call to adapter in FragmentActivity:
public void getApplicationListFromApi(List<Application> applicationList) {
this.applicationList = applicationList;
pageAdapter= new PageAdapter(getSupportFragmentManager(),this.getApplicationList());
pager.setAdapter(pageAdapter);
//Bind the title indicator to the adapter
TitlePageIndicator titleIndicator = (TitlePageIndicator)findViewById(R.id.titles);
titleIndicator.setViewPager(pager);
}
