TabLayout+ViewPager的基本使用

final List<String> list=new ArrayList<>();list.add("推荐");list.add("课程");list.add("实战");list.add("职业路径");vp.setOffscreenPageLimit(list.size());vp.setAdapter(new FragmentPagerAdapter(getChildFragmentManager()) {    @Override    public CharSequence getPageTitle(int position) {        return list.get(position);    }    @Override    public Fragment getItem(int position) {        FragmentXianq fragmentXianq = new FragmentXianq();        Bundle bundle=new Bundle();        bundle.putString("name",list.get(position));        fragmentXianq.setArguments(bundle);        return fragmentXianq;    }    @Override    public int getCount() {        return list.size();    }});tab.setupWithViewPager(vp);//xml如果在fragment当中的时候还得再在根布局中加xmlns:app="http://schemas.android.com/apk/res-auto"
