How can I get full URL (like below) from direct Firebase Storage for Android JAVA OR Kotlin

Question

我想得到这个完整的 URL：

https://firebasestorage.googleapis.com/v0/b/myapppakage-f7aa6.appspot.com/o/flat%2044%2F1image_1.jpg?alt=media&token=8907b845-a1f5-4bdb-8e76-215fc6fc519

我想使用完整的 URL 在 android slider 中显示图像。

我得到了这个 URL gs://myapppakage-f7aa6.appspot.com/flat 44/image_1.jpg
但我无法访问要在我的 slider 中显示的图像。

我的 Kotlin 代码

private fun retriveImagesFromStorage(flatName: String) {

 val firebaseStorage = FirebaseStorage.getInstance().reference
 val storageRef: StorageReference = firebaseStorage.child(flatName)

 storageRef.listAll().addOnSuccessListener { result ->
            // go through all the files/folders
            imageList.clear()
            result.items.forEach { storageRef ->
                // get the download URL for each of the file
               storageRef.downloadUrl.addOnSuccessListener { uri ->
                   imageList.add(uri.path.toString())
               }
            }
        }
        .addOnFailureListener {
            Toast.makeText(this, "Unable to fetch items!", Toast.LENGTH_SHORT).show()
            it.printStackTrace()
        }

}

检查此链接： https://firebase.google.com/docs/storage/android/download-files#download_data_via_url

val storageRef = Firebase.storage.reference
storageRef.child("folder/subfolder/picture.png").downloadUrl
    .addOnSuccessListener { url ->
        // do whatever with your url
    }
    .addOnFailureListener { exception ->
        Log.e(TAG, "Exception: ${exception.message}")
    }
