python - Kivy [按下按钮时冻结]

Question

所以我正在尝试学习简单的 Kivy GUI 来使用我之前已经制作的课程发送短信，除了窗口冻结几秒钟外，它可以工作，关于如何使按钮按下平滑而不冻结的任何提示？请记住，下面的代码只是应用程序的开始，只是为了确保它确实有效。提前致谢。

from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.gridlayout import GridLayout
from kivy.uix.textinput import TextInput
from kivy.uix.button import Button
from kivy.uix.widget import Widget
from kivy.uix.progressbar import ProgressBar
from kivy.config import Config

from sms_funksjon import SendSMS


Config.set('graphics', 'resizable', '0')  # 0 being off 1 being on as in true/false
Config.set('graphics', 'width', '500')
Config.set('graphics', 'height', '200')


class MyGrid(GridLayout):

    def __init__(self, **kwargs):
        super(MyGrid, self).__init__(**kwargs)

        self.cols = 1

        self.inside = GridLayout()
        self.inside.cols = 2

        self.inside.add_widget(Label(text="Mobil nummer: "), pow(50, 50))
        self.mobile_number = TextInput(multiline=False)
        self.inside.add_widget(self.mobile_number)

        self.inside.add_widget(Label(text="Tekst: "))
        self.tekst = TextInput(multiline=False)
        self.inside.add_widget(self.tekst)
        self.add_widget(self.inside)

        self.pb = ProgressBar(max=100)
        self.pb.value = 0
        self.add_widget(self.pb)

        self.submit = Button(text="Send", font_size=40)
        self.submit.bind(on_press=self.pressed)
        self.add_widget(self.submit)

    def pressed(self, instance):
        nummer = str(self.mobile_number.text)
        tekst = str(self.tekst.text)
        SendSMS(nummer, tekst)
        self.clear_everything()

    def clear_everything(self):
        self.mobile_number.text = ""
        self.tekst.text = ""


class Main(App):
    def build(self):
        return MyGrid()


Main().run()
