1、布局（必须要用线性布局）

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <com.youth.banner.Banner
        android:id="@+id/banner_recommend"
        android:layout_width="match_parent"
        android:layout_height="180dp" />

    <ProgressBar
        android:id="@+id/pb"
        style="@style/Widget.AppCompat.ProgressBar.Horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

2、适配器代码

 if (itemViewType == VIEW_TYPE_ONE) {
            ArrayList<String> images = new ArrayList<>();
            ArrayList<String> titles = new ArrayList<>();
            for (int i = 0; i < bannerListBeans.size(); i++) {
                images.add(bannerListBeans.get(i).getImage_url());
                titles.add(bannerListBeans.get(i).getTheme());
            }
            ViewHolder viewHolder = (ViewHolder) holder;
            viewHolder.pb.setMax(4);//进度为4
            viewHolder.pb.setProgress(1);//从1开始
            viewHolder.banner_recommend.setImages(images)
                    .setBannerTitles(titles)
                    .setBannerStyle(BannerConfig.NUM_INDICATOR_TITLE)
                    .setImageLoader(new ImageLoader() {
                        @Override
                        public void displayImage(Context context, Object path, ImageView imageView) {
                            Glide.with(context).load(path).into(imageView);
                        }
                    })
                    .start()
                    .setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
                        @Override
                        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

                        }

                        @Override
                        public void onPageSelected(int position) {
                            viewHolder.pb.setProgress(position + 1);
                        }

                        @Override
                        public void onPageScrollStateChanged(int state) {

                        }
                    });
