如何在ViewPager中更改特定页面的textView文本？

public class CustomPagerAdapter extends PagerAdapter {
    private Context context;
    private List<Fragment> fragments;

    public CustomPagerAdapter(Context context, List<Fragment> fragments) {
        this.context = context;
        this.fragments = fragments;
    }

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

    @Override
    public boolean isViewFromObject(@NonNull View view, @NonNull Object object) {
        return view == object;
    }

    @NonNull
    @Override
    public Object instantiateItem(@NonNull ViewGroup container, int position) {
        Fragment fragment = fragments.get(position);
        View view = fragment.getView();
        
        // 根据textView的id找到对应的textView控件
        TextView textView = view.findViewById(R.id.text_view);
        
        // 更改textView的文本内容
        textView.setText("新的文本内容");
        
        container.addView(view);
        return view;
    }

    @Override
    public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {
        container.removeView((View) object);
    }
}
