我在我的项目中使用导航抽屉,里面有5个片段.在一个片段中,我在设计支持库中引入了TabLayout,其中包括2个片段.一切正常,除非我离开具有TabLayout的片段并切换回它,所有内容都消失了.

在TabLayout的每个片段中,我有一个带有ListView的SwipeRefreshLayout,它们都不会在切换时显示任何内容.

我也注意到TabLayout开始表现得很奇怪.奇怪的是我的意思是白色指示器开始跳跃,你可以把它仍然保持在两个标签的中间......

所以我错过了TabLayout行为如此奇怪的事情吗？

这里的代码:包含TabLayout的片段:

public class MainFragment extends Fragment {
    private static String locale;
    private static ViewPager viewPager;
    private static TabLayout tabLayout;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        Utils.changeLanguage(getActivity());

        final Context contextThemeWrapper = new ContextThemeWrapper(getActivity(), R.style.MyStyle);

        LayoutInflater localInflater = inflater.cloneInContext(contextThemeWrapper);

        View view = localInflater.inflate(R.layout.fragment1, container, false);

        viewPager = (ViewPager) view.findViewById(R.id.viewpager);
        tabLayout = (TabLayout) view.findViewById(R.id.tabs);

        return view;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        setupViewPager(viewPager);
        tabLayout.setupWithViewPager(viewPager);
    }

    private void setupViewPager(ViewPager viewPager) {
        LinesTabsAdapter adapter = …

嗨我在片段中有一个TabLayout和ViewPager.但是我不能在tab之间滑动来到子片段(在Activity中正常工作但在片段中不起作用).

这是我的Tablayout内部片段的代码:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View inflateView = inflater.inflate(R.layout.fragment_assign_beacon_to_event, container, false);

        //Viewpager and TabLayout
        viewPager = (ViewPager)inflateView.findViewById(R.id.viewPager);
        viewPager.setAdapter(new CustomAdapter(getFragmentManager(), getContext()));

        tabLayout = (TabLayout)inflateView.findViewById(R.id.tabLayout);


        // Inflate the layout for this fragment
        return inflateView;
    }

@Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

    tabLayout.post(new Runnable() {
                @Override
                public void run() {
                    tabLayout.setupWithViewPager(viewPager);

            }
        });

        tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                viewPager.setCurrentItem(tab.getPosition());
            }

            @Override
            public void onTabUnselected(TabLayout.Tab tab) {
                viewPager.setCurrentItem(tab.getPosition());
            }

            @Override
            public void …
