TabLayout加載多個Fragment

首先我先說一下這個佈局就是TabLayout加ViewPager然後我們TabLayout的第一個是 Fragment跟其餘7個Fragment

加載的數據不一樣，看代碼把，代碼有註釋。

public class FragmentHd extends Fragment{

    public TabLayout hd_tl;
    public ViewPager hd_vp;
    List<String> listStr; //用於存放添加Fragment的結合
    List<Fragment> listTv;//用於存放Fragment的集合
    public TextView quanguo;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = View.inflate(getActivity(), R.layout.fragm_hd,null);
        //找控件
        hd_tl = view.findViewById(R.id.hd_tl);
        hd_vp = view.findViewById(R.id.hd_vp);
        quanguo = view.findViewById(R.id.quanguo);
        //TabLayout的橫向佈局  添加數據
        listStr = new ArrayList();
        listStr.add("全部");
        listStr.add("綜藝娛樂");
        listStr.add("財經訪談");
        listStr.add("文化旅遊");
        listStr.add("時尚體育");
        listStr.add("青少科技");
        listStr.add("養生保健");
        listStr.add("公益");
        listTv = new ArrayList<>();
        //第一個Fragment界面
        listTv.add(new FragmentQuan());
        listStr.get(0);
        //剩下的7個Fragment
        for (int i = 0; i < 7; i++) {
           listTv.add(new Fragments(listStr.get(i)));
        }
        //拿到適配器
        MyPagerAdapter adapter = new MyPagerAdapter(getChildFragmentManager());
        hd_vp.setAdapter(adapter);
        //ViewpAge的預加載解決方法
        hd_vp.setOffscreenPageLimit(listTv.size());
        //TabLayout和ViewPage進行聯動
        hd_tl.setupWithViewPager(hd_vp);
        return view;
    }

    //ViewPage的適配器
    class MyPagerAdapter extends FragmentPagerAdapter {

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

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

        @Override
        public int getCount() {
            return listTv.size();
        }
        @Override
        public CharSequence getPageTitle(int position) {
            return listStr.get(position);
        }
    }
}
