kivy线程没有与我一起工作(应用程序没有响应)

Question

你好，伙计们，当我开始运行一些功能时，我的kivy应用程序有问题，程序停止响应，我试图使用线程来解决这个问题，但它不起作用。

这是小部件类：

class PyWidget(Widget):
  stop = threading.Event()

  def start_thread(self): 
    self.ids.mic.source = 'assets/open2.png'
    self.ids.mic.reload()
    time.sleep(1)
    threading.Thread(target=self.start_listening).start();

    
  @mainthread
  def start_listening(self):
    while True:
      try:
        time.sleep(1)
        print('Listening.......')
        voiceText = RecognizeVoice()
        # time.sleep(1)
        if 'hello' in voiceText and Talking(App, respone, RecognizeVoice):
          return
        
        # else: Talking(App, respone, RecognizeVoice)
        time.sleep(1)
      except Exception as e:
        print(f'start_listening: {e}')

RecognizeVoice函数启动麦克风并将用户声音发送到文本

def RecognizeVoice():
  try:
    with speechRec.Microphone() as sound:
      voice = recognizer.listen(sound)
      voiceText = recognizer.recognize_google(voice, language="en-US") #online 
      voiceText = voiceText.lower()
      print(f'Input : {voiceText}')
      return voiceText
  except speechRec.UnknownValueError as e:
    print(f'RecognizeVoice: {e}')
  except speechRec.RequestError as e:
    print(f'RecognizeVoice: {e}')
    respone('Sorry, something went wrong.')

# Text to speech
def respone(message):
  AI.say(message)
  AI.runAndWait()

在我的GUI中，我有一个按钮，当我单击start_thread函数启动时，所有其他函数都跟着它，我希望我解释了所有的事情。谢谢你的帮助

@mainthread装饰器在start_listening()方法上击败threading。把那个装潢师移开。
