Question

我有一个具有用户名，电子邮件和个人资料图片的用户，但是我在注册时将个人资料图片设置为空字符串。我正在尝试更新个人资料照片并使用当前用户进行设置，但出现错误。

mProfilePic.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_PICK);
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(Intent.createChooser(intent, "Select Picture"), GALLERY_INTENT);
        }
    });

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == GALLERY_INTENT && resultCode == RESULT_OK && data != null && data.getData() != null){
        mainImageURI = data.getData();
        try {
            Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), mainImageURI);
            mProfilePic.setImageBitmap(bitmap);
            final ProgressDialog proDialog = new ProgressDialog(HomeActivity.this);
            proDialog.setTitle("Uploading...");
            proDialog.show();

            final StorageReference mRef = mStorage.child("Photos").child(mainImageURI.getLastPathSegment());
            mRef.putFile(mainImageURI).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    Task<Uri> uri = taskSnapshot.getMetadata().getReference().getDownloadUrl();
                    Log.i("uploaded", mDatabase.getReference("Users").child(mAuth.getCurrentUser().getUid()).child("image").setValue(uri).toString());
                    mDatabase.getReference("Users").child(mAuth.getCurrentUser().getUid()).child("image").setValue(uri).toString();
                    proDialog.dismiss();
                    Toast.makeText(HomeActivity.this, "Uploaded", Toast.LENGTH_LONG).show();
                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    proDialog.dismiss();
                    Toast.makeText(HomeActivity.this, "Upload Failed "+e.getMessage(), Toast.LENGTH_LONG).show();
                }
            })
            .addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                    double progress = (100.0*taskSnapshot.getBytesTransferred()/taskSnapshot.getTotalByteCount());
                    proDialog.setMessage("Uploaded "+(int)progress+"%");
                }
            });
        } catch(IOException e) {
            e.printStackTrace();
        }
    }
}

如果我删除了与用户连接有关的任何内容，则该代码有效。

这是我得到的错误：

Users->（uid）->用户名，电子邮件，图像当用户注册时，所有字段均为字符串，而image为null

这是更新个人资料图片的方法，然后可以基于mFirebaseUser对其进行调用。

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
        .setDisplayName("Jane Q. User")
        .setPhotoUri(Uri.parse("https://example.com/jane-q-user/profile.jpg"))
        .build();

user.updateProfile(profileUpdates)
        .addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                if (task.isSuccessful()) {
                    Log.d(TAG, "User profile updated.");
                }
            }
        });

如何为Firebase用户android更新个人资料图片？
