检索firebase存储映像并在UI中显示它

Question

我需要一些关于从firebase下载图像然后在UI上显示它的指导。我相信我能找到的正确下载文件，firebase注意到它已发送数据。我不能让我的生活得到它显示。任何帮助是极大的赞赏。

mAuth = FirebaseAuth.getInstance();
            FirebaseStorage storage = FirebaseStorage.getInstance();
            StorageReference jobRef = storage.getReferenceFromUrl("gs://********************.appspot.com/bd67a3b962538b24-0.jpg");


            final File localFile = File.createTempFile("jobNumbers","png");

            jobRef.getFile(localFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
                    // Local temp file has been created
                    StorageReference temp = taskSnapshot.getStorage();
                    Bitmap img = BitmapFactory.decodeFile(temp.getPath());
                    ImageView iv = (ImageView) findViewById(R.id.imageView);
                    iv.setImageBitmap(img);



                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception exception) {
                    // Handle any errors
                }
            });
