ActionBar Tabs with fragments on rotate

Question

I'am build an app with an ActionBar and two Tabs below. Everything works fine if the device / emulator isnt rotated. If rotated, tab state switches automaticale to tab1 (normal, because onCreate get called) but the content dont get changed. If I select a tab in the new orientation, the onCreateView() method from the selected Fragment get called but the view dont get updated (stay always the same). Any Tips?

The code.

Main Activity:

    ActionBar actionbar = getActionBar();
    actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    ActionBar.Tab ATab = actionbar.newTab().setText(R.string.player);
    ActionBar.Tab BTab = actionbar.newTab().setText(R.string.stations);

    Fragment AFragment = new AFragment();
    Fragment BFragment = new BFragment();

    PlayerTab.setTabListener(new MyTabsListener(AFragment));
    StationsTab.setTabListener(new MyTabsListener(BFragment));

    actionbar.addTab(ATab);
    actionbar.addTab(BTab);

With identical tabs that display a simple textview. The textview simple say which tab is selected.

Fragments:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.a, container, false);
}

The Fragment layout, mentioned above, only contains a TextView with hardcoded Text. (Only for testing purposes)

The Main layout looks like this.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >


    <LinearLayout
        android:id="@+id/fragment_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
 </LinearLayout>

</LinearLayout>

Do you want onCreate() to be called when the device is rotated? — nhaarman, Feb 08 '12 at 00:01
Yes and No, in this example is it ok. In final App, also Ok, but I think not the best way. Do you want use `android:configChanges="keyboardHidden|orientation"` ? I read about it and anyone said something about memory leaks and last resort. Is that right? Is there a better way? — Leandros, Feb 08 '12 at 00:06

Solved. I have recreated the fragment everytime, doesnt do that anymore solved it.

Changed in my TabListener and onTabSelected(Tab tab, FragmentTransaction ft), ft.add() to ft.replace()

This bug is also in the official Android docs: http://developer.android.com/guide/topics/ui/actionbar.html#Tabs Maybe someone can fix it there as well. – StefanMK Sep 10 '14 at 12:06
