<android.support.design.widget.TabLayout
    android:id="@+id/Tab_layout"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    app:tabGravity="center"
    app:tabIndicatorColor="@color/colorAccent"
    app:tabMode="scrollable"
    app:tabSelectedTextColor="@color/colorPrimaryDark"
    app:tabTextColor="@color/colorPrimary"
    >

</android.support.design.widget.TabLayout>
    <android.support.v4.view.ViewPager
        android:id="@+id/vp"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </android.support.v4.view.ViewPager>

java代码

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_home, container, false);
    tabLayout = (TabLayout) view.findViewById(R.id.Tab_layout);
    viewPager = (ViewPager) view.findViewById(R.id.vp);
    return view;
}

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    final List<String> list=new ArrayList<>();
    list.add("头条");
    list.add("社会");
    list.add("国内");
    list.add("娱乐");
    list.add("体育");
    list.add("军事");
    list.add("科技");
    list.add("财经");

    viewPager.setAdapter(new FragmentPagerAdapter(getChildFragmentManager()) {
        @Override
        public CharSequence getPageTitle(int position) {
            return list.get(position);
        }

        @Override
        public Fragment getItem(int position) {
            NewsFragment newsFragment=new NewsFragment();
            Bundle bundle=new Bundle();
            bundle.putString("name",list.get(position));
            newsFragment.setArguments(bundle);
            return newsFragment;
        }

        @Override
        public int getCount() {
            return list.size();
        }
    });
    tabLayout.setupWithViewPager(viewPager);

}
