我有一个Recycler View，显示了产品列表，每个 Recycler View 行项目中都有一个购物车图标。
点击购物车图标后，我希望产品图片能够复制、缩放并移动到右上角的操作栏上的购物车图标中。
我的方法：
在 RecyclerView 的行项目 XML 中创建了一个 ImageView，并最初将其设置为不可见。
当从 RecyclerView 点击购物车图标时，使该 ImageView 可见，并用图像 URL 填充 ImageView，并添加从起始位置到结束位置的平移动画。
当前结果：
图像在各自的单个项目行内移动，并在触及行项目边界后消失。我的意思是，图像没有出现在行项目之外，也没有到达顶部操作栏菜单项。
尝试的解决方案：
同时在xml中手动设置所有父级：
public static void setAllParentsClip(View v, boolean enabled) {
while (v.getParent() != null && v.getParent() instanceof ViewGroup) {
ViewGroup viewGroup = (ViewGroup) v.getParent();
viewGroup.setClipChildren(enabled);
viewGroup.setClipToPadding(enabled);
v = viewGroup;
}
}
同时在xml中手动设置所有父级：
android:clipChildren="false"
android:clipToPadding="false"
当图像触及行项目的边界后，它仍然会消失。任何建议都将是巨大的帮助。
我的RecyclerView适配器代码：
public class TrendingItemsAdapter extends RecyclerView.Adapter<TrendingItemsAdapter.MyViewHolder> {
private List<ProductEventDetail> productEventDetailList;
private Context context;
public TrendingItemsAdapter (List<ProductEventDetail> productEventDetailList){
this.productEventDetailList=productEventDetailList;

private TextView productName;

addToCart.setOnClickListener(this);
}
@Override
public void onClick(View v) {

//this is just a method call you can create to delete the animated view or hide it until you need it again.
animImg.setVisibility(View.GONE);
}
};
