<android.support.design.widget.TabLayout
android:id="@+id/tab"
android:layout_width=“0dp”
app:layout_constraintTop_toTopOf=“parent”
app:layout_constraintLeft_toLeftOf=“parent”
app:layout_constraintRight_toRightOf=“parent”
android:layout_height=“wrap_content”></android.support.design.widget.TabLayout>
<android.support.v4.view.ViewPager
android:id="@+id/Pager"
android:layout_width=“0dp”
android:layout_height=“0dp”

    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintLeft_toLeftOf="parent"

###适配器

public class Oneadapter extends FragmentPagerAdapter {
public String[] s = new String[]{
“关注”, “推荐”, “热点”, “科技”, “视频”, “数码”, “汽车”
};
public Oneadapter(FragmentManager fm) {
super(fm);
}

@Override
public Fragment getItem(int i) {
    return new FragmentTwo();
}

@Override
public int getCount() {
    return s.length;
}

@Nullable
@Override
public CharSequence getPageTitle(int position) {
    return s[position];
}

###核心代码

public class FragmentOne extends Fragment {
private ViewPager Pager;
private TabLayout tab;
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragmentone,container,false);
}

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
    Pager = view.findViewById(R.id.Pager);
    tab = view.findViewById(R.id.tab);
    Pager.setAdapter(new Oneadapter(getChildFragmentManager()));
    tab.setupWithViewPager(Pager);
}
