Question

我正在Kivy中创建可滚动的框布局，但是即使将框布局放在ScrollView中也无法滚动

from kivy.app import App
from kivy.lang import Builder
from kivy.base import runTouchApp
from kivy.uix.button import Button
from  kivy.uix.scrollview import ScrollView
kv = '''
ScrollView:
##    size=(root.width, root.height)
    do_scroll_y: True
    BoxLayout:
        orientation: 'vertical'

        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'
        Label:
            size_hint: (1,None)
            size: (100,100)
            text: 'my text'

class theApp(App):
    def build(self):
        return runTouchApp(Builder.load_string(kv))
if name == 'main':
    theApp().run()

预期结果是可滚动的框布局。但实际结果是不可滚动的。在搜索了ScrollView之后，我发现我只需要在其中放入布局即可，它很容易工作，但在这种情况下不行。让我知道我的错误是什么。

Answer 1

尝试为BoxLayout小部件设置高度限制，并将BoxLayout小部件的size_hint_y属性设置为“无”。

BoxLayout:
    size_hint_y: None
    height: self.minimum_height

    ...

我已经制作了可滚动的框布局，但无法滚动
