自定义基类属性的序列化(Custom Serialization of base class properties)

 我有一个类正在实现自定义序列化的ISerializable接口。 这适用于此类中的属性，但该类是派生类。 我遇到的问题是基类属性没有为我序列化。 基类具有可序列化的属性但不实现ISerializable。 有没有办法序列化基类属性，而不必在派生类的ISerializable .GetObjectData方法中手动添加所有这些属性？ 

I have a class that is implementing the ISerializable interface for custom serialization. This works great for the properties in this class but the class is a derived class. The problem i'm running into is that the base class properties aren't serialized for me. The base class has the serializable attribue but doesnt implement ISerializable. Is there a way to serialize the base class properties without having to add all of them manually in the derived class's ISerializable .GetObjectData method?

 对于这种类型的情况，有AnchorLayout ，用于将小部件与相对位置对齐。  
import kivy

from kivy.app import App
from kivy.uix.label import Label

from kivy.uix.boxlayout import BoxLayout
from kivy.lang import Builder

root = Builder.load_string('''
Screen:
    BoxLayout:
        orientation:'vertical'
        Label:
            text: '1'
            font_size: self.height
            size_hint: (1.0, 0.17)
        Label:
            text: '2'
            font_size: self.height
            size_hint: (1.0, 0.83)

    AnchorLayout:
        anchor_x: 'right'
        anchor_y: 'bottom'
        Label:
            text: '3'
            font_size: self.height
            size_hint: None, None
''')

class MyApp(App):
    def build(self):
        root.size_hint = (1.0, 1.0)
        return root

if __name__ == '__main__':
    MyApp().run()
 
  

For this type of cases there is AnchorLayout, which serves to align the widgets to a relative position. 
import kivy

from kivy.app import App
from kivy.uix.label import Label

from kivy.uix.boxlayout import BoxLayout
from kivy.lang import Builder

root = Builder.load_string('''
Screen:
    BoxLayout:
        orientation:'vertical'
        Label:
            text: '1'
            font_size: self.height
            size_hint: (1.0, 0.17)
        Label:
            text: '2'
            font_size: self.height
            size_hint: (1.0, 0.83)

    AnchorLayout:
        anchor_x: 'right'
        anchor_y: 'bottom'
        Label:
            text: '3'
            font_size: self.height
            size_hint: None, None
''')

class MyApp(App):
    def build(self):
        root.size_hint = (1.0, 1.0)
        return root

if __name__ == '__main__':
    MyApp().run()
