我是 Kivy 的新手，遇到了問題。我有“MainPanel”類，它包含四個類“導(dǎo)航”、“圖像”、“配置”和“信息”。我想要的是當(dāng)在“導(dǎo)航”類中按下按鈕時，然后在“信息”類中使用屏幕管理器更改當(dāng)前屏幕。這是我的代碼：Main.py：class Navigation(FloatLayout): passclass Information(ScreenManager): passclass SlothFacts(Screen): passclass KiwiFacts(Screen): passclass MainPanel(GridLayout): passBuilder.load_file("mainPanel.kv")class Complex(App): def build(self): return MainPanel()if __name__ == "__main__": Complex().run()主面板.kv：#:include navigation.kv#:include images.kv#:include config.kv#:include information.kv<MainPanel>: cols:2 Navigation: Images: Config: Information:導(dǎo)航.kv：<Navigation>: Button: text:"Kiwi" size_hint:(.3, .2) pos_hint:{'x':.1, 'y':.25} #on_press: <--- Change screen to kiwi in Information class資料.kv：#: import FadeTransition kivy.uix.screenmanager.FadeTransition<Information> transition: FadeTransition() SlothFacts: KiwiFacts:<SlothFacts>: name: "sloth" Label: text:"im sloth"<KiwiFacts>: name: "kiwi" Label: text:"im kiwi"

在文件中添加一個id，例如：ScreenManagermainPanel.kv
#:include navigation.kv
#:include images.kv
#:include config.kv
#:include information.kv
<MainPanel>:
cols:2
Navigation:
Images:
Config:
Information:
id: screenManager
然后，在您的Navigation.kv文件中使用它：
<Navigation>:
Button:
text:"Kiwi"
size_hint:(.3, .2)
pos_hint:{'x':.1, 'y':.25}
#on_press: <--- Change screen to kiwi in Information class
on_press: app.root.ids.screenManager.current='kiwi'
