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
