Kivy：如何在boxlayout中添加垂直滚动条

Question

我用Python（test.py）和kivy（test.kv）编写了一些代码。

 谁能告诉我如何在我的boxLayout中添加垂直滚动条？

我正在使用

滚动型：
     do_scroll_y：真实      do_scroll_x：错误         BoxLayout的：
            方向：“垂直”

但我想也许我在某个地方犯了错误。

当我使用scrollView时，设计被破坏

test.py

from kivy.uix.screenmanager import Screen
from kivy.app import App
from kivy.lang import Builder
from kivy.core.window import Window


Window.clearcolor = (0.5, 0.5, 0.5, 1)
Window.size = (600, 700)

class ACgroup(Screen):
    pass


class TestACgroup(App):

    def build(self):
        self.root = Builder.load_file('test.kv')
        return self.root


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

test.kv

<CustomLabel@Label>:
    text_size: self.size
    #padding_x: 5

<GreenButton@Button>:
    background_color: 1, 1, 1, 1
    size_hint_y: None
    height: self.parent.height * 0.100

当您使用垂直滚动视图时，您必须设置唯一的孩子的高度，如下所示：

ScrollView:
    BoxLayout:
        size_hint_y: None
        height: #the height that you want
