TabLayout橫向滑動菜單

在TabLayoutFragment中的代碼

 private TabLayout draw;
    private ViewPager pager2;
    private List<String> list = new ArrayList<>();

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment03, container, false);

        draw = (TabLayout) view.findViewById(R.id.draw);
        pager2 = (ViewPager) view.findViewById(R.id.pager2);
        list.add("精選");
        list.add("英倫風");
        list.add("直播");
        list.add("訂閱");
        list.add("視頻購");
        list.add("問答");

        MyF3Adapter f3Adapter = new MyF3Adapter(getChildFragmentManager(),list,getActivity());
        pager2.setAdapter(f3Adapter);

        draw.setTabMode(draw.MODE_FIXED);
        draw.setupWithViewPager(pager2);
        return view;
    }

在FragmentAdapter中的代碼
首先繼承FragmentPagerAdapter
重寫5個方法

private List<String> list;
    private Context context;

    public MyF3Adapter(FragmentManager fm, List<String> list, Context context) {
        super(fm);
        this.list = list;
        this.context = context;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return list.get(position);
    }

    public MyF3Adapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {

        if (position == 0) {

            F1 f1 = new F1();
            return f1;
        } else if (position == 1) {

            F2 f2 = new F2();
            return f2;
        } else if (position == 2) {

            F3 f3 = new F3();
            return f3;
        } else if (position == 3) {

            F4 f4 = new F4();
            return f4;
        } else if (position == 4) {

            F5 f5 = new F5();
            return f5;
        }else if(position==5){

            F6 f6 = new F6();
            return f6;
        }

        return null;
    }

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