实现原理：安卓adb截图传到电脑，然后用python裁剪获得两张数字图片，使用ddddocr识别数字，比较大小，再用adb命令模拟安卓手势实现><

<code>import os

import ddddocr

from time import sleep

from PIL import Image

def take_screenshot(path):

"""从设备截取屏幕并保存到指定路径。"""

os.system(f'adb shell screencap -p > {path}')

# 读取截取的屏幕截图并替换行结束符

with open(path, 'rb') as f:

return f.read().replace(b'\r\n', b'\n')

return img.crop(crop_area)

"""提取图片中的文本。"""

with open(img, 'rb') as f:

img_bytes = f.read()

res = ocr.classification(img_bytes)

return res.replace(' ', '').replace('\n', '')

def compare_numbers(x, y):

"""比较两个数字并相应地执行滑动操作。"""

try:

x_int, y_int = int(x), int(y)

os.system("adb shell input swipe 850 1800 450 1900 1")
