So I'm learning about Firebase Storage for android and I've hit a wall. I want to get all the images I have stored in a folder in my Firebase Storage and once I get a reference to them I want to stored them in a ListView or RecyclerView. How Do i do that? I mean I can get reference to the folder:

StorageReference storageReference =  FirebaseStorage.getInstance().getReference("gallery");

但是然后如何获取Gallery文件夹中的所有图像并将它们显示在Listview或recyclerView中?

But then how do I get all the images in the gallery folder and display them in a Listview or recyclerView?

推荐答案

Firebase Storage当前没有API调用可列出文件夹中的所有文件.如果需要这种功能，则应将文件的元数据(例如下载URL)存储在可以列出它们的位置. Firebase实时数据库非常适合此操作，您还可以轻松与他人共享URL.

There currently is no API call in Firebase Storage to list all files in a folder. If you need such functionality, you should store the metadata of the files (such as the download URLs) in a place where you can list them. The Firebase Realtime Database is perfect for this and allows you to also easily share the URLs with others.

将图像名称添加到 Firebase实时数据库并获取

add image name to the Firebase Realtime Databse and fetch from it

并获得类似的网址，

mStoreRef.child("<folderNameInStorage>/" +""<imageName>).getDownloadUrl().addOnSuccessListener();

这就是方法.
