android - 如何使用带有底部导航的可滑动标签

Question

您好，我一直在尝试使用带底部导航栏的滑动标签，但是在重新选择标签时滑动缺失并且没有任何显示。我正在从底部栏 fragment 中调用滑动选项卡的 fragment 。这是我的代码

    public class WalletFragment extends Fragment {
    private ViewPager viewPager;
    private WalletTabsAdapter mAdapter;
    PagerSlidingTabStrip wallettabs;
    // Tab titles

    public static WalletFragment newInstance(int instance) {
        Bundle args = new Bundle();
        args.putInt("input", instance);
        WalletFragment fragment = new WalletFragment();
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_wallet, container, false);
        // Initilization
        viewPager = (ViewPager) rootView.findViewById(R.id.walletpager);
        wallettabs = (PagerSlidingTabStrip) rootView.findViewById(R.id.wallettabs);
        mAdapter = new WalletTabsAdapter(getFragmentManager());
        viewPager.setAdapter(mAdapter);
        wallettabs.setViewPager(viewPager);
        /**
         * on swiping the viewpager make respective tab selected
         * */
        return rootView;
    }
}

使用 getChildFragmentManager() 而不是 getFragmentManager() 。参见 viewpager didnt show anything after change bottom navigation menu.我试过了，效果很好
