如何在运行时在ViewPager2中添加/删除选项卡？仅使用一个片段

// 创建适配器类
public class MyPagerAdapter extends FragmentStateAdapter {
    private List<Fragment> fragmentList;

    public MyPagerAdapter(FragmentManager fragmentManager, Lifecycle lifecycle) {
        super(fragmentManager, lifecycle);
        fragmentList = new ArrayList<>();
    }

    public void addFragment(Fragment fragment) {
        fragmentList.add(fragment);
        notifyDataSetChanged();
    }

    public void removeFragment(Fragment fragment) {
        fragmentList.remove(fragment);
        notifyDataSetChanged();
    }

    @Override
    public int getItemCount() {
        return fragmentList.size();
    }

    @NonNull
    @Override
    public Fragment createFragment(int position) {
        return fragmentList.get(position);
    }
}

// 在Activity或Fragment中使用ViewPager2和适配器
ViewPager2 viewPager2 = findViewById(R.id.viewPager2);
MyPagerAdapter adapter = new MyPagerAdapter(getSupportFragmentManager(), getLifecycle());
viewPager2.setAdapter(adapter);

// 添加选项卡
Fragment newFragment = new YourFragment();
adapter.addFragment(newFragment);

// 删除选项卡
Fragment fragmentToRemove = fragmentList.get(position);
adapter.removeFragment(fragmentToRemove);
