如何在Tablayout中更新片段？(Viewpager2，FragmentStateAdapter)

<androidx.constraintlayout.widget.ConstraintLayout
    ...
    >

    <com.google.android.material.tabs.TabLayout
        android:id="@+id/tabLayout"
        ...
        />

    <androidx.viewpager2.widget.ViewPager2
        android:id="@+id/viewPager"
        ...
        />

</androidx.constraintlayout.widget.ConstraintLayout>

TabLayout tabLayout = findViewById(R.id.tabLayout);
ViewPager2 viewPager = findViewById(R.id.viewPager);

public class MyAdapter extends FragmentStateAdapter {

    private List<Fragment> fragments;

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

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

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

List<Fragment> fragments = new ArrayList<>();
fragments.add(new Fragment1());
fragments.add(new Fragment2());
fragments.add(new Fragment3());

MyAdapter adapter = new MyAdapter(getSupportFragmentManager(), getLifecycle(), fragments);
viewPager.setAdapter(adapter);

new TabLayoutMediator(tabLayout, viewPager, (tab, position) -> {
    // 设置Tab的标题
    tab.setText("Tab " + (position + 1));
}).attach();
