如何检索 Firebase 存储中的一个特定图像？

Question

For example there are 10 folders in a storage and each folder have 5 images. How do I retrieve one specific image from each folder in a loop? or any methods.

Answer 1

Nevermind I got it.

I don't know if this is right but i just named the images some incrementing numbers using loop and retrieve the first one by calling "0".

But please if you have any suggestions, I would be glad.

Answer 2

Currently, there is no way to list all files in a folder in the Firebase Storage. If you need such a functionality, you will have to store the metadata of the files (such as the download URLs) where you can list them. I think Firebase Realtime Database is good to use.

add image name to the other place and fetch from it

and get Url like

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