如何在删除碎片时动态更新ViewPager

public class MyPagerAdapter extends FragmentPagerAdapter {
    private List<Fragment> fragments;

    public MyPagerAdapter(FragmentManager fm) {
        super(fm);
        fragments = new ArrayList<>();
    }

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

    @Override
    public int getCount() {
        return fragments.size();
    }

    public void updateFragments(List<Fragment> newFragments) {
        fragments.clear();
        fragments.addAll(newFragments);
        notifyDataSetChanged();
    }
}

// 创建适配器对象
MyPagerAdapter adapter = new MyPagerAdapter(getSupportFragmentManager());

// 设置适配器给ViewPager
ViewPager viewPager = findViewById(R.id.viewPager);
viewPager.setAdapter(adapter);

// 删除碎片的逻辑
List<Fragment> newFragments = new ArrayList<>(adapter.getCount());
for (int i = 0; i < adapter.getCount(); i++) {
    Fragment fragment = adapter.getItem(i);
    if (!shouldDelete(fragment)) {
        newFragments.add(fragment);
    }
}
adapter.updateFragments(newFragments);
