本篇不介入kv语言，直接在主程序堆砌控件

 1 from kivy.app import App
 2 from kivy.uix.label import Label
 3 from kivy.core.text import LabelBase
 4 from kivy.uix.textinput import TextInput
 5 from kivy.uix.gridlayout import GridLayout
 6 
 7 LabelBase.register("Roboto", "msyhl.ttc")
 8 
 9 
10 class LoginScreen(GridLayout):
11     """主布局,加入相关控件对象"""
12 
13     def __init__(self):
14         super().__init__()
15         self.cols = 2
16         self.add_widget(Label(text="用户名"))
17         self.username = TextInput(multiline=False)
18         self.add_widget(self.username)
19         self.add_widget(Label(text="密码"))
20         self.password = TextInput(password=True, multiline=False)
21         self.add_widget(self.password)
22 
23 
24 class Test(App):
25     def build(self):
26         """重写该方法"""
27         # 返回根控件位置
28         return LoginScreen()
29 
30 
31 if __name__ == '__main__':
32     Test().run()
