Question

在我的项目中关于使用swipe查看多个活动我已经使用了片段的想法和我的代码工作得非常好，但是今天早上我的经理让我将片段的数组列表转换为数组活动列表但我真的不知道我怎么能做到这一点请任何帮助这是我的代码

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;
        }
    }

    public static class FragmentOne extends Fragment {

        public static final String ARG_SECTION_NUMBER = "section_number";

        public FragmentOne() {}

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

您进入MainActivity的项目使用Fragments no Activities

我认为如果你想使用Swipe视图，你不能使用Array Activities，因为Swipe View它基于ViewPager并且需要片段。

所以我觉得用“活动”“滑动视图”是不可能的。

抱歉我的英文。

我如何使用活动的数组列表而不是使用多个片段
