我正在尝试创建一个屏幕，该屏幕在页面顶部具有水平的滚动视图，占据约25％的垂直空间，而垂直的滚动视图则占据其余空间（然后可以滚动在屏幕下方）。
我已经设法创建了水平滚动视图，但是无法使垂直滚动视图在同一屏幕上工作。
py文件：
import kivy
from kivy.app import App
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.lang import Builder
from kivy.uix.label import Label
from kivy.uix.button import Button
from kivy.uix.image import Image
from
Window.clearcolor = (1,1,1,1)
class Window(Screen):
pass
class MyApp(App):
theme_cls = ThemeManager()
def build(self):
kv = Builder.load_file("kivy.kv")
self.sm = WindowManager()
screens = [Window(name="window")]
for screen in screens:
self.sm.add_widget(screen)
self.sm.current = "window"
return self.sm
if __name__ == '__main__':
MyApp().run()

我希望它们彼此独立，因此您既可以在顶部滚动视图上水平滚动，也可以通过垂直滚动视图上的框布局上的按钮进行垂直滚动

花了一些时间才能使您的MCVE正常工作，但这是kv的一部分，我进行了修改，使两个ScrollViews可以双向滚动：
ScrollView: #horizontal
size_hint_y: 0.25
do_scroll_y: False
GridLayout:
rows: 1
id: scroll_horizontal
size_hint: None, 1

width: self.minimum_width*1.3
spacing: 20

cols: 2
spacing: 10
size_hint_x: None
width: self.minimum_width
Button:
size_hint: None, 1
width: 500
