如何在片段之间实现带有viewpager的广告？

// 布局文件中的ViewPager和指示器
<androidx.viewpager.widget.ViewPager
    android:id="@+id/viewPager"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

<com.example.indicator.Indicator
    android:id="@+id/indicator"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

// 创建适配器类
public class AdPagerAdapter extends PagerAdapter {
    private List<String> adUrls; // 广告图片的URL列表
    private Context context;

    public AdPagerAdapter(List<String> adUrls, Context context) {
        this.adUrls = adUrls;
        this.context = context;
    }

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

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        ImageView imageView = new ImageView(context);
        // 使用图片加载库加载广告图片
        Glide.with(context).load(adUrls.get(position)).into(imageView);
        container.addView(imageView);
        return imageView;
    }

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

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

// 在Activity或Fragment中使用ViewPager和适配器
ViewPager viewPager = findViewById(R.id.viewPager);
Indicator indicator = findViewById(R.id.indicator);

List<String> adUrls = new ArrayList<>();
adUrls.add("http://example.com/ad1.jpg");
adUrls.add("http://example.com/ad2.jpg");
adUrls.add("http://example.com/ad3.jpg");

AdPagerAdapter adapter = new AdPagerAdapter(adUrls, this);
viewPager.setAdapter(adapter);
indicator.setViewPager(viewPager);

// 设置ViewPager的页面切换监听器
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        // 页面滚动时更新指示器的显示
        indicator.setCurrentPosition(position);
    }

    @Override
    public void onPageSelected(int position) {
    }

    @Override
    public void onPageScrollStateChanged(int state) {
    }
});
