當我嘗試從我的 Firebase 存儲中設置圖像時，我的 ImageView 消失了

Question

我想從我的存儲中設置一張 Picasso 的圖片，但是它不起作用。 最初，我的 ImageView 中有一個圖標，但進入 Activity 后它並沒有顯示。

這是代碼

public class ProfileFragment extends Fragment {

    TextView fullNameText, emailText, dateBirthText, phoneText;
    TextView addressText;
    FloatingActionButton profileEditBtn;
    TextView uploadImgBtn;
    ImageView profileImg;

    String phone, link;

    private DatabaseReference dbRef = FirebaseDatabase.getInstance().getReference().child("image");


    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        Bundle bundle = this.getArguments();
        phone = bundle.getString("phone");

        View myView = inflater.inflate(R.layout.fragment_profile, container, false);

        fullNameText = myView.findViewById(R.id.full_name_text);
        emailText = myView.findViewById(R.id.email_text);
        dateBirthText = myView.findViewById(R.id.date_birth_text);
        addressText = myView.findViewById(R.id.address_text);
        phoneText = myView.findViewById(R.id.phone_text);
        profileImg = myView.findViewById(R.id.profile_img);


        uploadImgBtn = myView.findViewById(R.id.upload_img_btn);
        uploadImgBtn.setOnClickListener(view -> {
            Intent intent = new Intent(getContext(), UploadProfileImage.class);
            intent.putExtra("phone", phone);
            startActivity(intent);
        });

        return myView;
    }

    @Override
    public void onStart() {
        super.onStart();

        dbRef.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                link = dataSnapshot.getValue(String.class);
                // this is the link to the image in firebase
                System.out.println(link);

                Picasso.get()
                        .load(link)
                        .fit()
                        .centerCrop()
                        .into(profileImg);

                profileImg.setVisibility(View.VISIBLE);
            }

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

            }
        });
    }
}

我試過用 Glide 代替 picasso，但不管怎樣都沒用。 我也很確定我的文件鏈接是正確的。

實時數據庫

{
  "Users" : {
    "123456789" : {
      "address" : "",
      "date" : "2022-03-27",
      "email" : "admin@gmail.com",
      "fullName" : "me",
      "password" : "qwerty12345",
      "phone" : "123456789"
    }
  },
  "image" : "gs://myproj-8984f.appspot.com/images/gachiava.png"
}

請檢查畢加索是否可以通過手動添加url來加載另一個url。

Picasso.get().load("your link here").fit().centerCrop().into(profileImg);

並確保您已將正確的 inte.net 權限添加到 Android 清單。
