Android使用ViewPager进行不同的滑动指示

Question

我有一个应用程序，我使用ViewPager进行滑动。到目前为止，我只能刷RightToLeft。我想要的是滑动RightToLeft，向下滑动并向上滑动。我有3个片段，但它只刷了RightToLeft。

ReflectionTestUtils.setField(new FxRatesEventPublisher(),"maxRecoveryAge",1,int.class);
ReflectionTestUtils.setField(new FxRatesEventPublisher(),"maxRecoveryAge",5,int.class);
ReflectionTestUtils.setField(new FxRatesEventPublisher(),"maxRecoveryAge",24,int.class);

}

这是ViewPager代码

public class MainActivity extends FragmentActivity {

FragmentPagerAdapter adapterViewPager;

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

    CustomViewPager vpPager = (CustomViewPager) findViewById(R.id.view_pager);
    adapterViewPager = new MyPagerAdapter(getSupportFragmentManager());
    vpPager.setAdapter(adapterViewPager);

    vpPager.getCurrentItem();

    // Attach the page change listener inside the activity
    vpPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {

        // This method will be invoked when a new page becomes selected.
        @Override
        public void onPageSelected(int position) {
        }

        // This method will be invoked when the current page is scrolled
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
            // Code goes here
        }

        // Called when the scroll state changes:
        // SCROLL_STATE_IDLE, SCROLL_STATE_DRAGGING, SCROLL_STATE_SETTLING
        @Override
        public void onPageScrollStateChanged(int state) {
            // Code goes here
        }
    });

}

public static class MyPagerAdapter extends FragmentPagerAdapter {
    private static int NUM_ITEMS = 3;

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

    // Returns total number of pages
    @Override
    public int getCount() {
        return NUM_ITEMS;
    }

    // Returns the fragment to display for that page
    @Override
    public Fragment getItem(int position) {
        switch (position) {
            case 0: // Fragment # 0 - This will show FirstFragment
                return FirstFragment.newInstance(0);
            case 1:
                return SecondFragment.newInstance(1);
            case 2:
                return ThirdFragment.newInstance(2);
            default:
                return null;
        }
    }

}

}

任何可以帮助我添加2个swioe指示的人？
