Как получить все ваши элементы хранения firebase с помощью метода 'listall ()'?

---

i know the documentation do it like this

     listRef.listAll()
    .addOnSuccessListener(new OnSuccessListener<ListResult>() {
        @Override
        public void onSuccess(ListResult listResult) {
            for (StorageReference prefix : listResult.getPrefixes()) {
                // All the prefixes under listRef.
                // You may call listAll() recursively on them.
            }

            for (StorageReference item : listResult.getItems()) {
                // All the items under listRef.
            }
        }
    }) 

но как я могу получить свои данные из элемента? например uri изображения или метаданные

public class Wallpaper {
private String wallpaperName;
private Uri imageUri;


public Wallpaper(String wallpaperName, Uri imageUri) {
    this.wallpaperName = wallpaperName;
    this.imageUri = imageUri;
}

public Wallpaper() {
}

public String getWallpaperName() {
    return wallpaperName;
}

public void setWallpaperName(String wallpaperName) {
    this.wallpaperName = wallpaperName;
}

public Uri getImageUri() {
    return imageUri;
}

public void setImageUri(Uri imageUri) {
    this.imageUri = imageUri;
}
}





public class ShowWallpapers extends AppCompatActivity {

private RecyclerView recyclerView;
private RecyclerViewAdapter recyclerViewAdapter;

private List<Wallpaper> wallpaperList;
private StorageReference storageReference;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_show_wallpapers);

    storageReference = FirebaseStorage.getInstance().getReference("wallpapers");

    recyclerView = findViewById(R.id.recyclerview);
    recyclerView.setHasFixedSize(true);

    recyclerView.setLayoutManager(new LinearLayoutManager(this));

    wallpaperList = new ArrayList<>();


    storageReference.listAll()
            .addOnSuccessListener(new OnSuccessListener<ListResult>() {
                @Override
                public void onSuccess(ListResult listResult) {
                    for (StorageReference item : listResult.getItems()) {
                   // i want to set-up my Wallpaper object here and add it to my list
                  // but how can i do that


                    }
                    recyclerViewAdapter = new RecyclerViewAdapter(ShowWallpapers.this,
                            wallpaperList);
                    recyclerView.setAdapter(recyclerViewAdapter);
                }


            }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {

        }
    });
}
}
