不幸的是，我在 kivy 和 Python 3 中遇到了錯誤。我還沒有通過 Google 找到解決方案。我想至少獲得文本輸入，但它沒有顯示出來。只是文字本身。感謝您的時間！import kivykivy.require('1.10.1') # replace with your current kivy version !from kivy.app import Appfrom kivy.uix.floatlayout import FloatLayoutfrom kivy.uix.textinput import TextInputfrom kivy.uix.label import Labelclass ColdKivyApp(App): def build(self): f = FloatLayout() label = Label(text="Cold") #I acutally orginally called it Zone unitil I changed it into Cold cause it's really cold now f.add_widget(label) txt = TextInput(text='', focus=True, multiline=True, cursor_blink=True, background_color=(1,1,1,1)) f.add_widget(txt) return fif __name__ == '__main__': ColdKivyApp().run()

在構(gòu)造函數(shù)中設(shè)置焦點時，TextInput 中似乎存在一個錯誤，解決方法是在窗口顯示后立即設(shè)置焦點Clock：
import kivy
kivy.require('1.10.1') # replace with your current kivy version !
from kivy.app import App
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.textinput import TextInput
from kivy.uix.label import Label
from kivy.clock import Clock
class ColdKivyApp(App):
def build(self):
f = FloatLayout()
label = Label(text="Cold")
f.add_widget(label)
txt = TextInput(multiline=True, cursor_blink=True, background_color=(1,1,1,1))
f.add_widget(txt)
Clock.schedule_once(lambda *args: setattr(txt, "focus", True))
return f
if __name__ == '__main__':
ColdKivyApp().run()
