如何在 Android 中使用 .setPhotoUri 从本地存储添加图片以更新 Firebase 用户的照片配置文件？

Question

我在 Firebase 中更新用户的照片配置文件时出错。 我想将用户的本地照片上传到 Firebase 用户的个人资料。 这是我的活动。

                                    if (task.isSuccessful()) { //success on updating user profile
                                        Toast.makeText(EditProfile.this, "Update Profile Succedeed",
                                                Toast.LENGTH_SHORT).show();
                                        startActivity(new Intent(EditProfile.this, HomePage.class));
                                    } else { //failed on updating user profile
                                        Toast.makeText(EditProfile.this, "Update Profile Failed",
                                                Toast.LENGTH_SHORT).show();
                                    }
                                }
                            });
                }

            }
        });

        //setting image for user
        mImageBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
                galleryIntent.setType("image/*");
                startActivityForResult(galleryIntent, GALLERY_REQUEST);

            }
        });

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == GALLERY_REQUEST && resultCode == RESULT_OK){
            Uri imageUri = data.getData();
            mImageBtn.setImageURI(imageUri);
            imageUri2 = imageUri;
        } else {
            Toast.makeText(EditProfile.this, "Failed showing image",
                    Toast.LENGTH_SHORT).show();
        }
    }
}

这是我从 Firebase 获取用户个人资料的方式：

  String email = user.getEmail();
        String username = user.getDisplayName();
        Uri uriImage = user.getPhotoUrl();
        mUserName.setText(username);
        mUserStat.setText(email);
    mUriImageProfile.setImageURI(uriImage);

感谢您的回复。

您需要从您的设备获取此图像，将文件放入 firebase，然后将其用作链接

您可以检查我的 github 以查看它是否有效https://github.com/chrystianmelo/appmodule
