从Firebase存储中检索图像：-

StorageReference ref = mImageStorage.child("image table name")
                    .child("image name"+ ".jpg");

    ref.getDownloadUrl().addOnCompleteListener(new OnCompleteListener<Uri>() {
                        @Override
                        public void onComplete(@NonNull Task<Uri> task) {
                            if (task.isSuccessful()) {
                                Uri downUri = task.getResult();
                                String imageUrl = downUri.toString();
                                // now you can use imageUrl anywhere you want
                            }

                        }
                    });
