Android ViewPager 删除带有动画的项目

Question

我有布局作为页面的viewpager。我尝试在单击deleteBtn 时删除带有动画的项目。如果页面没有滚动，它几乎可以工作（活动刚刚加载了 viewpager）。如果页面被更改，动画不会出现，但项目会像往常一样删除。请帮我修复删除时的动画外观。

@Override
public Object instantiateItem(ViewGroup collection, int position) {
    LayoutInflater inflater = LayoutInflater.from(context);
    ViewGroup layout = (ViewGroup) inflater.inflate(R.layout.item_home_pager, collection, false);
    ImageView deleteBtn = (ImageView) layout.findViewById(R.id.like_btn);
    deleteBtn.setOnClickListener(v -> {
        Animation animation = AnimationUtils.loadAnimation(context, R.anim.slide_to_top);
        layout.startAnimation(animation);           
        removeItem(position);
    });
    collection.addView(layout);
    return layout;
}

public void removeItem(int position) {
    personModels.remove(position);
    notifyDataSetChanged();
}


@Override
public int getItemPosition(Object object) {
    return PagerAdapter.POSITION_NONE;
}


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

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

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