【问题描述】：
我正在尝试制作一个监控应用程序，您可以在其中切换哪个统计信息将是主要小部件。我想有一个屏幕管理器，然后为每个统计数据设置单独的屏幕，但似乎会有更好的方法。
下面是我的 kv 文件，其中每个布局都有单独的屏幕，工具栏位于屏幕之外：
<Mytest>
GridLayout
cols: 1
size: root.size
StackLayout:
orientation: 'lr-tb'
size_hint_y: .05
Button:
text: "pog"
size_hint_x: .1
background_color: (0, 0, 0, 0)
on_press: root.ids.manager.current = 'first'
Button:
text: "p"
size_hint_x: .1
background_color: (0, 0, 0, 0)
on_press: root.ids.manager.current = 'second'
Button:
text: " o"
size_hint_x: .1
background_color: (0, 0, 0, 0)
on_press: root.ids.manager.current = 'third'

on_press: root.ids.manager.current = 'fourth'
