python3+uiautomator2多设备使用执行（多线程，不能并行设备执行）

多设备使用多线程执行，不能并行，只能一个设备执行完成后面，执行另一个设备

import sys
import uiautomator2  as u2
from time import sleep
import os
import subprocess
import threading
import time

def MultiDevice( d):  # 功能执行

    d.screen_on()
    # print(d.info)
    d.screen_off()

def getphonelist():  # 获取手机设备
    cmd = r'adb devices'  # % apk_file
    pr = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True)
    pr.wait()  # 不会马上返回输出的命令，需要等待
    out = pr.stdout.readlines()  # out = pr.stdout.read().decode("UTF-8")
    devices = []
    for i in (out)[1:-1]:
        device = str(i).split("\\")[0].split("'")[-1]
        devices.append(device)
    return devices  # 手机设备列表



def test_xxx(i):
    d = u2.connect(i)  # d = u2.connect('192.168.1.117')#  uiautomator2 连接手机
    MultiDevice(d)

        for t in threads:
            time.sleep(0.3)
            t.start()
