java - 我无法使用 Firebase 存储编辑封面图片和个人资料图片。我的程序有什么问题？

Question

我在我的项目中添加了用户配置文件页面，即 ProfileFragment.java，它的布局文件是 fragment_profile.xml。我想更新用户信息，如姓名、描述、个人资料图片和封面。我的程序没有错误，名称和描述更新成功但封面和头像没有更新？我的代码有什么问题？

这是我的 ProfileFragment.java

ByteArrayOutputStream我建议在将 Bitmap 转换为not后尝试保存它URI。

您可以按如下方式获取用户选择的位图 -

....
Bitmap newImage;                 //make it a global variable
.....

    @Override
        public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            if (resultCode != RESULT_CANCELED) {
                switch (requestCode) {
                    case 0:                            //Image from Camera
                        if (resultCode == RESULT_OK && data != null) {
                            newImage = (Bitmap) data.getExtras().get("data");
                            userImage.setImageBitmap(newImage);
                            newImageSet = true;
                        }
    
                        break;
                    case 1:                           //Image from gallery/user device
                        if (resultCode == RESULT_OK && data != null) {
                            Uri selectedImage = data.getData();
                            String[] filePathColumn = {MediaStore.Images.Media.DATA};
                            if (selectedImage != null) {
                                Cursor cursor = getActivity().getContentResolver().query(selectedImage,
                                        filePathColumn, null, null, null);
                                if (cursor != null) {
                                    cursor.moveToFirst();
                                    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                                    String picturePath = cursor.getString(columnIndex);
                                    newImage = BitmapFactory.decodeFile(picturePath);
                                    userImage.setImageBitmap(newImage);
                                    cursor.close();
                                }
                            }
                        }
                        break;
                }
            }
        }

获得新图像 bitmp 后，您可以将 Bitmap 放入 Firstore。

public void saveImageToFirbase(){

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
            newImage.compress(Bitmap.CompressFormat.JPEG, 40, byteArrayOutputStream);
            StorageReference imgReference = FirebaseStorage.getInstance().getReference()
                    .child("User Profile Image")   
                    .child(FirebaseAuth.getInstance().getCurrentUser().getUid() + ".jpeg");
                    //adjust imgReference according to your database structure 

            imgReference.putBytes(byteArrayOutputStream.toByteArray())
                    .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                        @Override
                        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                            getDownloadUrl(imgReference);
                            
                        }
                    })
                    .addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception e) {
                            Log.e(TAG, "onFailure: ", e.getCause());
                        }
                    });
}

这里Bitmap.CompressFormat.JPEG, 40整数值将是压缩级别。

方法 getgetDownloadUrl() -

private void getDownloadUrl(StorageReference storageReference) {
    storageReference.getDownloadUrl()
            .addOnSuccessListener(new OnSuccessListener<Uri>() {
                @Override
                public void onSuccess(Uri uri) {
                    setUserProfileUrl(uri);
                }
            });
} 

至少您可以更新用户的个人资料并设置 ImageUrl -

private void setUserProfileUrl(Uri userProfileUrl) {
    FirebaseUser firebaseUser = FirebaseAuth.getInstance().getCurrentUser();

    UserProfileChangeRequest userProfileChangeRequest = new UserProfileChangeRequest.Builder()
            .setPhotoUri(userProfileUrl).build();
    firebaseUser.updateProfile(userProfileChangeRequest)
            .addOnSuccessListener(new OnSuccessListener<Void>() {
                @Override
                public void onSuccess(Void aVoid) {
                    //some more update in your view
                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Log.e(TAG, "onFailure: ", e.getCause());
                }
            });
}

快乐编码！
