我是 kivy 的新手并使用了一些教程，但我只在視頻開發(fā)人員在屏幕上顯示他們的小部件時(shí)出現(xiàn)黑屏。import kivyfrom kivy.app import Appfrom kivy.uix.label import Labelfrom kivy.uix.gridlayout import GridLayoutfrom kivy.uix.textinput import TextInputclass MyGrid(GridLayout): def __int__(self, **kwargs): super(MyGrid, self).__int__(**kwargs) self.cols = 2 self.add_widget(Label(text="Name: ")) self.name = TextInput(multiline=False) self.add_widget(self.name) self.add_widget(Label(text="last name : ")) self.lastName = TextInput(multiline=False) self.add_widget(self.lastname) self.add_widget(Label(text="email: ")) self.emailName = TextInput(multiline=False) self.add_widget(self.emailname)class MyApp(App): def build(self): return MyGrid()if __name__ == "__main__": MyApp().run()

您在代碼中有一些拼寫錯(cuò)誤。第一個(gè)是關(guān)于__init__您拼寫的函數(shù)__int__ 您還使用不同的變量來(lái)分配一個(gè)小部件，并使用一個(gè)類似的（但不同的）來(lái)添加它（例如self.lastName = TextInput(multiline=False)和self.add_widget(self.lastname)）
此代碼應(yīng)該可以工作：
from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.gridlayout import GridLayout
from kivy.uix.textinput import TextInput
class MyGrid(GridLayout):
def __init__(self, **kwargs):
super(MyGrid, self).__init__(**kwargs)
self.cols = 2
self.add_widget(Label(text="Name: "))
self.name = TextInput(multiline=False)
self.add_widget(self.name)
self.add_widget(Label(text="last name : "))
self.lastName = TextInput(multiline=False)
self.add_widget(self.lastName)
self.add_widget(Label(text="email: "))
self.emailName = TextInput(multiline=False)
self.add_widget(self.emailName)
class MyApp(App):
def build(self):
return MyGrid()
if __name__ == '__main__':
MyApp().run()
