我對 Python 和 Kivy 都是新手。我們正在為一項作業開發此應用程序，我正在處理首選項頁面。我的標簽、文本輸入、切換按鈕和按鈕都位于正確的位置并且可以正常工作，但我正在努力解決如何獲取這些按鈕的輸出?；旧?，當有人按下確認按鈕時，我想打印這樣的輸出：Name: BlablaMood reminders: 2 per dayDiary reminders: 1 per day我認為 on_press 不起作用，因為每次按下按鈕時都會打印一個值，而不是僅在按下確認時打印一個值?，F在我的 .py 代碼如下所示from kivy.app import Appfrom kivy.lang import Builderfrom kivy.uix.floatlayout import FloatLayoutfrom kivy.properties import ObjectProperty# Builder.load_file('preferences.kv')class MyFloatLayout(FloatLayout): name = ObjectProperty(None) def mood_buttons(self): pass def diary_buttons(self): pass def print_specs(self): print("Name: " + self.name.textclass PreferencesApp(App): def build(self): return MyFloatLayout()if __name__ == '__main__': PreferencesApp().run()我的 .kv 語言文件如下所示<Label> font_size: 20<TextInput> font_size: 20<Checkbox> size_hint_x: .20<MyFloatLayout>: name: name FloatLayout: Label: text: "Name: " size_hint: 0.4, 0.08 pos_hint:{"x": 0.1, "center_y": 0.85} TextInput: id: name multiline: False size_hint: 0.4, 0.07 pos_hint:{"x":0.5,"center_y":0.85} Label: text: "How many mood reminders would you like?" size_hint: 0.5, 0.1 pos_hint: {"center_x": 0.5, "top": 0.75} BoxLayout: pos_hint: {'center_x': 0.5, 'y': 0.55} size_hint: 0.8, 0.1 ToggleButton: text:"Zero" id: m0 group: "mood_popups" on_press: self.mood_buttons() ToggleButton: text:"1 per day" id: m1 group: "mood_popups" ToggleButton: text:"2 per day" id: m2 group: "mood_popups" ToggleButton: text:"3 per day" id: m3 group: "mood_popups"

Buttons您可以使用該方法訪問組中的所有內容get_widgets()。所以你的print_specs()方法可以是：
def print_specs(self):
print("Name: " + self.name.text)
# get mood reminder
mood_reminder = ''
for toggle in ToggleButton.get_widgets('mood_popups'):
if toggle.state == 'down':
mood_reminder = toggle.text
break
print('Mood reminders:', mood_reminder)
# get diary reminder
diary_reminder = ''
for toggle in ToggleButton.get_widgets('diary_popups'):
if toggle.state == 'down':
diary_reminder = toggle.text
break
print('Diary reminders:', diary_reminder)
