username_dialog.xml 即可。仅包含与图像视图和文本相关的代码

                        String cell = cellField.getText().toString();

                        // license plate no.
                        EditText plateField = (EditText)((AlertDialog) dialog).findViewById(R.id.licenseNo);

                        String userId = FirebaseAuth.getInstance().getCurrentUser().getUid();

                        User aUser = new User(username, year, cmm, cell, licenseNo);


                        /*  https://android-chat-af94c.firebaseio.com/android-chat-af94c/
                            users/pRsxsToJZPTzCdtft69f1grIJC13/profile/username

                            getInstance -> grabbing the url:
                            https://android-chat-af94c.firebaseio.com/android-chat-af94c/
                        */
                        // above is the same as below ...
                        FirebaseDatabase.getInstance().getReference("drivers").child(userId).setValue(aUser);

                        Intent intent = new Intent(getActivity().getBaseContext(), PoliciesActivity.class);
                        startActivity(intent);
                    }

                });

                builder.setNeutralButton(R.string.action_take_pic, new DialogInterface.OnClickListener() {
                    @Override
                    public final void onClick(final DialogInterface dialog, int id) {


                    }
                });

        return builder.create();

    }

} // UsernameDialogFragment

onActivityResult 现在这适用于许可照片

// take photo
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)  {
    super.onActivityResult(requestCode, resultCode, data);

    filepath = data.getData();

    Bitmap bitmap = (Bitmap)data.getExtras().get("data");
    license_photo.setImageBitmap(bitmap);

} // onActivityResult

非常感谢任何帮助。

我不确定你真正想要存档的内容。但是，在AFAIK中，您应该保存对话框ImageView以随时更改其图像：

View dialogView = inflater.inflate(R.layout.username_dialog, null);
// save imageview as global variable 
ImageView avatar = dialogView.findViewId(R.id.imageview_avatar);
builder.setView(dialogView);
//you can change imageview later after user picks image.
Glide....into(avatar);

在“警报”对话框中创建类似配置文件图片的图像
