android - 複数のフラグメントを使用する代わりにアクティビティの配列リストを使用するにはどうすればよいですか

Question

スワイプで複数のアクティビティを表示する私のプロジェクトでは、フラグメントのアイデアを使用しており、コードは非常にうまく機能しますが、今朝、マネージャーからフラグメントの配列リストをアクティビティの配列リストに変換するように依頼されましたが、実際にはそうしませんこれを行う方法を知ってくださいこれは私のコードです

public class MainActivity extends FragmentActivity {

    SectionsPagerAdapter mSectionsPagerAdapter;
    ViewPager mViewPager;
    List < Fragment > fragments;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Create the adapter that will return a fragment for each of the three
        // primary sections of the app.
        fragments = new Vector < Fragment > ();

        fragments.add(Fragment.instantiate(this, FragmentOne.class.getName()));
        fragments.add(Fragment.instantiate(this, FragmentTwo.class.getName()));
        fragments.add(Fragment.instantiate(this, FragmentThree.class.getName()));
        fragments.add(Fragment.instantiate(this, FragmentFour.class.getName()));
        fragments.add(Fragment.instantiate(this, FragmentFive.class.getName()));
        fragments.add(Fragment.instantiate(this, FragmentSix.class.getName()));

        mSectionsPagerAdapter = new SectionsPagerAdapter(super.getSupportFragmentManager());

        // Set up the ViewPager with the sections adapter.
        mViewPager = (ViewPager) findViewById(R.id.pager);
        mViewPager.setAdapter(mSectionsPagerAdapter);
    }

    public class SectionsPagerAdapter extends FragmentPagerAdapter {

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

        @Override
        public Fragment getItem(int position) {
            int _pos = position % 6;
            return fragments.get(_pos);
        }

        @
        Override
        public int getCount() {
            // Show 3 total pages.
            return 6;
        }

        @
        Override
        public CharSequence getPageTitle(int position) {
            final String title_section4 = "Section4";
            final String title_section5 = "Section5";
            final String title_section6 = "Section6";
            final String title_section1 = "Section1";
            final String title_section2 = "Section2";
            final String title_section3 = "Section3";

            Locale l = Locale.getDefault();
            switch (position) {
                case 0:
                    return title_section1.toUpperCase(l);
                case 1:
                    return title_section2.toUpperCase(l);
                case 2:
                    return title_section3.toUpperCase(l);
                case 3:
                    return title_section4.toUpperCase(l);
                case 4:
                    return title_section5.toUpperCase(l);
                case 5:
                    return title_section6.toUpperCase(l);
            }

            return null;
        }
    }
