如何最好地在viewpager中实现回收视图？

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

    public MyPagerAdapter(FragmentManager fm, List<Fragment> fragments) {
        super(fm);
        this.fragments = fragments;
    }

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

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

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        super.destroyItem(container, position, object);
        // 销毁不可见的Fragment
        Fragment fragment = fragments.get(position);
        if (fragment != null) {
            FragmentTransaction ft = ((FragmentActivity) container.getContext()).getSupportFragmentManager().beginTransaction();
            ft.remove(fragment);
            ft.commitAllowingStateLoss();
        }
    }

    @Override
    public int getItemPosition(Object object) {
        // 返回POSITION_NONE，以便在数据集发生变化时刷新所有页面
        return POSITION_NONE;
    }
}

List<Fragment> fragments = new ArrayList<>();
// 添加需要显示的Fragment
fragments.add(new Fragment1());
fragments.add(new Fragment2());
fragments.add(new Fragment3());

MyPagerAdapter adapter = new MyPagerAdapter(getSupportFragmentManager(), fragments);
ViewPager viewPager = findViewById(R.id.viewPager);
viewPager.setAdapter(adapter);
