以数组列表或列表的形式从 firebase 存储中检索图像，然后将其发送到 firestore，稍后可以检索该图像以填充多个 img

这些是下面定义的参考文献；

StorageReference strgRef;
FirebaseFirestore mfirestore;
ArrayList<String> files,status;
List<String> downloadedimages;
RecyclerView recview;
ImageView btn_upload;
myadapter adapter;

我有一个画廊意图，然后是activityforResults从图库中选择多个图像，代码将所选图像列表上传到cloud firebase存储，但我试图以 URI 的形式取回它，以便我可以发送这些 URI 来创建 firestore 集合，然后从 firestore 取回它以填充 imagesscroll 视图。[lets take an example of a product details page of amazon where multiple images of a product are displayed that is what I am trying to achieve with the above query]需要注意的是，我想使用我的手机上传这些图像。

没有错误，来自 Uri successlistener 的代码块不起作用，它也不记录从 firebase storage 获取的 URI。我想从存储中存储这些 URI，然后将其放入云 Firestore 中，其中包含一个包含这些图像 Uri 列表的集合。我正在寻找一个解决方案，它将帮助我将这些 URI 存储到 arraylist 或列表中，稍后可以将其发送到 Firestore 就是这样。谢谢阅读！ –
