I guess you want to do something like this:

FirebaseStorage storage = FirebaseStorage.getInstance();
StorageReference listRef = storage.getReference().child("Wallpapers");

listRef.listAll()
        .addOnSuccessListener(listResult -> {
            // All the items under listRef.
            images.addAll(listResult.getItems());
            adapter.notifyDataSetChanged();
            //....
        })
        .addOnFailureListener(e -> {
            // Uh-oh, an error occurred!
            Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
            //...
        });

Edit: images is an ArrayList object like this:

private ArrayList<StorageReference> images;
