1、activity中代码

@Override
public void initData() {
    super.initData();
    tab=new ArrayList<>();
    vp=new ArrayList<>();
    tab.add("修理厂人脉");
    tab.add("供应商人脉");
    tab.add("技师人脉");
    tab.add("车主人脉");
    vp.add(new Fragment_XiuLiChang());
    vp.add(new Fragment_GongYingShang());
    vp.add(new Fragment_JiShi());
    vp.add(new Fragment_CheZhu());
}

@Override
public void initEvent() {
    super.initEvent();
    people_quan_ViewPager.setAdapter(new Fragment_ViewPage(getSupportFragmentManager(),vp,tab));
    people_quan_tabLayout.setupWithViewPager(people_quan_ViewPager);
}

2、Fragment_ViewPage中代码：

public class Fragment_ViewPage extends FragmentPagerAdapter {
    private List<Fragment> fragments;
    private List<String> fragment_title;
    public Fragment_ViewPage(FragmentManager fm,List<Fragment> fragments,List<String> fragment_title) {
        super(fm);
        this.fragments=fragments;
        this.fragment_title=fragment_title;
    }

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

    @Override
    public int getCount() {
        return fragments.size();
    }
    //配置标题的方法
    @Override
    public CharSequence getPageTitle(int position) {
        return fragment_title.get(position);
    }
}
