如何在安卓ImageView上设置2张以上的图片

<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">
    <item android:drawable="@drawable/image1" android:duration="1000" />
    <item android:drawable="@drawable/image2" android:duration="1000" />
    <item android:drawable="@drawable/image3" android:duration="1000" />
</animation-list>

ImageView imageView = findViewById(R.id.imageView);
imageView.setBackgroundResource(R.drawable.animation);
AnimationDrawable animationDrawable = (AnimationDrawable) imageView.getBackground();
animationDrawable.start();

<androidx.viewpager.widget.ViewPager
    android:id="@+id/viewPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

public class ImagePagerAdapter extends PagerAdapter {
    private List<Integer> imageList;

    public ImagePagerAdapter(List<Integer> imageList) {
        this.imageList = imageList;
    }

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

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

    @NonNull
    @Override
    public Object instantiateItem(@NonNull ViewGroup container, int position) {
        ImageView imageView = new ImageView(container.getContext());
        imageView.setImageResource(imageList.get(position));
        container.addView(imageView);
        return imageView;
    }

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

ViewPager viewPager = findViewById(R.id.viewPager);
List<Integer> imageList = new ArrayList<>();
imageList.add(R.drawable.image1);
imageList.add(R.drawable.image2);
imageList.add(R.drawable.image3);
ImagePagerAdapter adapter = new ImagePagerAdapter(imageList);
viewPager.setAdapter(adapter);
