viewpager2中的Fragmentstateadapter未在导航体系结构组件中显示片段

// 在布局文件中添加ViewPager2组件
<androidx.viewpager2.widget.ViewPager2
    android:id="@+id/viewPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

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

    public MyAdapter(FragmentManager fragmentManager, List<Fragment> fragments) {
        super(fragmentManager, getLifecycle());
        this.fragments = fragments;
    }

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

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

// 在主活动或片段中设置适配器
ViewPager2 viewPager = findViewById(R.id.viewPager);
List<Fragment> fragments = new ArrayList<>();
fragments.add(new Fragment1());
fragments.add(new Fragment2());
MyAdapter adapter = new MyAdapter(getSupportFragmentManager(), fragments);
viewPager.setAdapter(adapter);

// 如果需要使用导航组件，可以在导航图中定义目标片段，并在导航过程中使用NavController导航到对应的片段
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupWithNavController(viewPager, navController);
