Android:TabLayout没有显示任何标签

return inflater.inflate(R.layout.fragment_home, container, false);

在你的onCreateView意思是你没有任何初始化代码返回一个新膨胀的主片段.

您应该返回您在开头创建的视图onCreateView:

return v;

提供标签标题的示例PagerAdapter:

public class PagerAdapter extends FragmentPagerAdapter {
    private final List mFragments = new ArrayList<>();
    private final List mFragmentTitles = new ArrayList<>();

    public PagerAdapter(FragmentManager fm) {
        super(fm);
    }

    public void addFragment(Fragment fragment, String title) {
        mFragments.add(fragment);
        mFragmentTitles.add(title);
    }

    @Override
    public Fragment getItem(int position) {
        return mFragments.get(position);
    }

    @Override
    public int getCount() {
        return mFragments.size();
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return mFragmentTitles.get(position);
    }
}

因此,您重构的onCreateView代码将类似于:

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

    View v = inflater.inflate(R.layout.fragment_home, container, false);

    final TabLayout tabLayout = (TabLayout) v.findViewById(R.id.tabLayout);
    final ViewPager viewPager = (ViewPager) v.findViewById(R.id.viewpager);
    PagerAdapter adapter = new PagerAdapter(getFragmentManager());
    adapter.addFragment(BlogFragment.newInstance(), "One");
    adapter.addFragment(TrendingFragment.newInstance(), "Two");

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


    return v;
}
