从 Firebase 存储下载照片

Question

我已经尝试了我找到的所有方法，但仍然没有用，所以我写在这里

我正在尝试从我的文件夹“images”中的 Firebase 存储下载照片，其中的文件与当前授权用户 ID 同名。这里唯一的问题是它不起作用。仅显示对象的背景（我正在更改 ShapableImageView 上的照片）

下面我从应用程序添加代码、日志和照片。

代码：

  private void downloadProfile() {

    User localUser = new User("","","0","","",0,0,0);
    if(mAuth.getCurrentUser()!=null){
        database_ref.child("users").child(mAuth.getCurrentUser().getUid()).addListenerForSingleValueEvent(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot snapshot) {
                if(snapshot.exists()){
                    localUser.name = snapshot.child("name").getValue().toString();
                    localUser.mail = mAuth.getCurrentUser().getEmail();
                    localUser.age = snapshot.child("age").getValue().toString();
                    localUser.phone = snapshot.child("phone").getValue().toString();
                    localUser.address = snapshot.child("address").getValue().toString();
                    localUser.login_method = Integer.parseInt(snapshot.child("login_method").getValue().toString());
                    localUser.playlist_amount = Integer.parseInt(snapshot.child("playlist_amount").getValue().toString());
                    localUser.fav_song_amount = Integer.parseInt(snapshot.child("fav_song_amount").getValue().toString());

                    profile_email.setText(localUser.mail);
                    profile_name.setText( localUser.name);
                    age_edit_t.setText(localUser.age);
                    phone_edit_t.setText(localUser.phone);
                    address_edit_t.setText(localUser.address);

                    //  Image download
                    storageReference = storage.getReferenceFromUrl("gs://altas-notas.appspot.com");

                    storageReference.child("images/"+mAuth.getCurrentUser().getUid()+".jpg").getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                        @Override
                        public void onSuccess(Uri uri) {
                            profile_img.setImageURI(uri);
                        }
                    }).addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception exception) {
                            // Handle any errors
                        }
                    });

               
                }
            }

            @Override
            public void onCancelled(@NonNull DatabaseError error) {

            }
        });
    }
}

无论我如何尝试下载并将照片设置为透明或默认。

如果重要，我还添加了更改图像的部分代码：

    private void startGallery() {
    Intent cameraIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    cameraIntent.setType("image/*");
    if (cameraIntent.resolveActivity(getActivity().getPackageManager()) != null) {
        startActivityForResult(cameraIntent, 1000);
    }
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    //super method removed
    if (resultCode == RESULT_OK) {

        if (requestCode == 1000) {
             returnUri = data.getData();
            Bitmap bitmapImage = null;
            try {
                bitmapImage = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), returnUri);
                profile_img.setImageBitmap(bitmapImage);
            } catch (IOException e) {
                e.printStackTrace();
            }


            //Upload image

            storageReference = FirebaseStorage.getInstance().getReference();
            storageReference.child("images/"+mAuth.getCurrentUser().getUid()).putFile(returnUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {
                    if(task.isSuccessful()){
                        System.out.println("Upload image is successful!");

                    }else{
                        System.out.println("Upload image failed!");

                    }
                }
            });
            //Upload rest of information
            updateProfile();
        }
    }

}

Answer 1

在您的代码中：

storageReference.child("images/"+mAuth.getCurrentUser().getUid()+".jpg")

您不需要 .jpg。像这样尝试：

storageReference.child("images/"+mAuth.getCurrentUser().getUid())
