双向无限动态ViewPager

双向无限/动态ViewPager

这会有所帮助吗？

public static class MyAdapter extends FragmentPagerAdapter {    public MyAdapter(FragmentManager fm) {        super(fm);    }    @Override    public int getCount() {        return Integer.MAX_VALUE;    }    @Override    public Fragment getItem(int position) {        return getFragmentbasedonPosition(position);    }    private Fragment getFragmentbasedonPosition(int position) {        int fragmentPos = position % 3; // Assuming you have 3 fragments        switch(fragmentPos) { case 1: return Fragment1.newInstance(); case 2: return Fragment2.newInstance(); case 3: return Fragment3.newInstance();        }    }}

然后，

mPager.setCurrentItem((int)(Integer.MAX_VALUE/2));

//假设mPager是您的ViewPager
