Question

我有一个活动，启动一个包含4个标签的片段，每个标签显示一个列表视图，每当我定向到横向时，标签和列表视图都会正确显示但是当我回到垂直，列表视图或我放入的任何内容时标签从中途开始......其余部分是空白的。确切的位置在哪里我相信这个问题必须与我的android有关：configChanges =“orientation | screenSize”

入职前 http://i1366.photobucket.com/albums/r761/Aeonia92/Screenshot_2015-09-04-10-54-05_zpshdo11fx0.jpeg

迎新之后 http://i1366.photobucket.com/albums/r761/Aeonia92/Screenshot_2015-09-04-11-01-26_zpsptfuvzwj.jpeg

如果我在底层活动的清单中移除此行，那么应用程序一旦转到横向，就会丢失所有内容，包括片段选项卡，以显示空页。

有没有以编程方式执行此操作？

public class ViewPagerFragment extends Fragment {

public List<TabPagerItem> mTabs = new ArrayList<>();
private Context context;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    context = getActivity();
    createTabPagerItem();
}

private void createTabPagerItem() {

    mTabs.add(new TabPagerItem(getText(R.string.all), HomeFragment.newInstance(getString(R.string.all))));
    mTabs.add(new TabPagerItem(getText(R.string.print), PrintFragment.newInstance(getString(R.string.print))));
    mTabs.add(new TabPagerItem(getText(R.string.radio), RadioFragment.newInstance(getString(R.string.radio))));
    mTabs.add(new TabPagerItem(getText(R.string.tv), TVFragment.newInstance(getString(R.string.tv))));
    //mTabs.add(new TabPagerItem(getText(R.string.tv), MainFragment.newInstance(getString(R.string.tv))));
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_viewpager, container, false);
    rootView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
    return rootView;
}

@Override
public void onSaveInstanceState(final Bundle outState) {
     super.onSaveInstanceState(outState);
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

}


@Override
public void onViewCreated(final View view, Bundle savedInstanceState) {
    final ViewPager mViewPager = (ViewPager) view.findViewById(R.id.viewPager);
    //pages to store in memory

    mViewPager.setOffscreenPageLimit(mTabs.size());

    mViewPager.setAdapter(new ViewPagerAdapter(getChildFragmentManager(), mTabs));


    getActivity().runOnUiThread(new Runnable() {
        public void run() {
            (new ViewPagerAdapter(getChildFragmentManager(), mTabs)).notifyDataSetChanged();
        }
    });

    TabLayout mSlidingTabLayout = (TabLayout) view.findViewById(R.id.tabLayout);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        mSlidingTabLayout.setElevation(15);
    }
    mSlidingTabLayout.setupWithViewPager(mViewPager);
}

示例片段

public static HomeFragment newInstance(String text) {
    HomeFragment mFragment = new HomeFragment();
    Bundle mBundle = new Bundle();
    mBundle.putString("f", text);
    mFragment.setArguments(mBundle);
    return mFragment;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.homelist, container, false);

    setHasOptionsMenu(true);
    ((MainActivity) getActivity())
            .setActionBarTitle("Latest Mentions");

    context = getActivity();
    info = new Db(context);
    anime = AnimationUtils.loadAnimation(getActivity(), R.anim.slide_up);
    New();

    rootView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
    return rootView;
}

片段ListView方向错误
