ActionBar旋转时带有片段的选项卡

[英]ActionBar Tabs with fragments on rotate

I'am build an app with an ActionBar and two Tabs below. 我正在构建一个带有ActionBar和下面两个标签的应用程序。 Everything works fine if the device / emulator isnt rotated. 如果设备/模拟器没有旋转,一切正常。 If rotated, tab state switches automaticale to tab1 (normal, because onCreate get called) but the content dont get changed. 如果旋转,选项卡状态会自动切换到tab1(正常,因为onCreate被调用)但内容不会更改。 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). 如果我在新方向中选择一个选项卡, onCreateView()调用所选FragmentonCreateView()方法,但视图不会更新(始终保持不变)。 Any Tips? 有小费吗?

The code. 代码。

Main Activity: 主要活动:

    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. 使用相同的选项卡显示简单的文本视图。 The textview simple say which tab is selected. textview简单说明选择了哪个选项卡。

Fragments: 片段:

@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. 上面提到的Fragment布局只包含带有硬编码Text的TextView。 (Only for testing purposes) (仅用于测试目的)


The Main layout looks like this. Main布局如下所示。

<?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>

Solved. 解决了。 I have recreated the fragment everytime, doesnt do that anymore solved it. 我每次都重新创建片段,不再这样做了解决它。

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