你需要用到这个

 .addOnCompleteListener(new OnCompleteListener<Uri>() {
    @Override
    public void onComplete(@NonNull Task<Uri> task) {
        if (task.isSuccessful()) {
            Uri downloadUri = task.getResult();
            if (downloadUri != null) {
                String photoStringUrl = downloadUri.toString();
            }
        }
    }
});
