        if (selectedPhotoUri == null) return
        val filename = UUID.randomUUID().toString()
        val ref = FirebaseStorage.getInstance().getReference("/Users/$filename")
        ref.putFile(selectedPhotoUri!!)
                .addOnSuccessListener {
                    ref.downloadUrl.addOnSuccessListener {
                        url = it.toString()
                        store(url!!)
                    }
                }
                .addOnFailureListener {
                    Toast.makeText(this, "", Toast.LENGTH_LONG).show()

                }
    }

首先，您需要获取要删除的照片的参考。您可以使用图像的url或其他方法来访问图像的引用。以下代码直接来自Firebase文档。

StorageReference desertRef = mFirebaseStorage.getReferenceFromUrl(mImageUrl);

// Delete the file
desertRef.delete().addOnSuccessListener(new OnSuccessListener<Void>() {
    @Override
    public void onSuccess(Void aVoid) {
        // File deleted successfully
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception exception) {
        // Uh-oh, an error occurred!
    }
});
