 自动获取toast，当有toast时，截图保存并语音播报：

import uiautomator2 as u2
import win32com.client
from datetime import datetime

d = u2.connect()

while True:
    toast = d.toast.get_message(wait_timeout=5)
    if toast:
        print(toast)  # 打印toast信息
        d.screenshot('./IMG/%stoast.jpg' % datetime.now().strftime('%Y%m%d%H%M%S'))  # 截图保存
        speaker = win32com.client.Dispatch("SAPI.SpVoice")  # 语音播放获取到的toast信息
        speaker.Speak(toast)
        d.toast.reset()  # 在验证成功后及时清除缓存
