上代码

from PIL import Image
import os

    pngPath = r"D:\adb\screen.png"
    pixelX = x
    pixelY = y
    img_src = Image.open(pngPath)
    img_src = img_src.convert('RGB')
    str_strlist = img_src.load()
    data = str_strlist[pixelX, pixelY]
    img_src.close()
    return data


while True:
    os.system(r"D:\adb\adb.exe shell screencap /sdcard/screen.png")
    os.system(r"D:\adb\adb.exe pull /sdcard/screen.png D:\adb")
    if getPngPix(480,2154) == (250, 157, 59): #扫描红包颜色
        os.system(r"D:\adb\adb.exe shell input tap 580 2041") #点击红包
        os.system(r"D:\adb\adb.exe shell screencap /sdcard/screen.png")
