不用图像识别，就可以拿到微信性别。
先上一张图片，
通过红框里的小头像可以看出是男是女，或者未知。
我们可以通过判断头像来获取性别，识别男女。
但是太麻烦和复杂了。
其实我们可以通过界面元素进行拾取当前性别
首先打开安卓的界面层级拾取工具 一般位于安卓sdk包下tools下 的uiautomatorviewer.bat
我们发现根本不需要通过图像识别，就轻而易举的拿到性别了。
这是手动获取的，那我们怎样自动获取呢。
我们可以通过程序进行获取，
比如 appium自动化测试工具，adb命令，android自动化测试Uiautomator框架 等。。
首先appium 需要配置很多环境，Uiautomator框架要在android里实现。
而adb命令比较通用，python调用adb也很方面。
那我们就用adb写自动获取代码。
通过uiautomatorviewer.bat我们拿出当前的xml代码
（点击uiautomatorviewer界面上左上角水平第四个按钮保存即可）
当前页面的全部xml代码（经过格式化以后的排版，默认是一行）：
<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>

一共有三种状态
1 content-desc="男"
2 content-desc="女"
3 就是 连这个xml源码也没有 ，也就是对方性别未知的意思。
全部的xml源码都是以node为节点，我们要做的就是匹配出 男 女 未知
那我们首先要找寻到上面那一行xml部分源码
也就是找到包含 resource-id="com.tencent.mm:id/anl" 为基准的节点，包含在<node></node>
为什么不直接去匹配 男 女这种字眼呢？
原因是姓名和地区中可能包含 男 女 字眼，我们要准确匹配。
所以我们先找到包含resource-id="com.tencent.mm:id/anl"的这一行，
因为resource-id="com.tencent.mm:id/anl"在全部的xml代码中是唯一的，
再从这一行中拿出性别，那就很准确了。
现在思路就是：
1 首先获取手机设备
2 电脑端使用python程序通过adb命令控制手机
3 拿出手机端的页面
4 进行匹配并打印
开始我们的编写我们的代码：
import os,re
# 获取所有的手机设备
def getDevicesAll():
devices = []
try:
for dName_ in os.popen("adb devices"):
if "\t" in dName_:
if dName_.find("emulator") < 0:
devices.append(dName_.split("\t")[0])
devices.sort(cmp=None, key=None, reverse=False)
except:
pass
print(u"\n设备名称: %s \n总数量:%s台" % (devices, len(devices)))
return devices
# 导出手机端当前页面元素
def export(devices_name):
# 页面xml保存到手机存储
step1 = os.popen('adb -s {0} shell uiautomator dump /sdcard/{1}.xml'.format(devices_name,devices_name)).read()
if step1.find('UI') != -1:
print(devices_name+'\txml写进手机存储成功')
# 页面xml从手机存储推送到电脑，和当前运行程序同级
os.popen('adb -s {0} pull /sdcard/{1}.xml '.format(devices_name,devices_name))
print(devices_name+"\txml推送到电脑成功")
with open(devices_name + ".xml",encoding="utf-8") as f:
res = f.read()
return res
else:
print(devices_name+"\txml写进手机存储失败")
return "null"
# 匹配函数
def check_line(res,find_str):
list1 = re.findall( '<[^<]*?' + find_str + '[^>]*?>', res)
if list1:
return list1[0]
return "null"
def main():
# 以resource-id为基准进行匹配
findstr = 'resource-id="com.tencent.mm:id/anl"'
devices = getDevicesAll()
for d_name in devices:
res = export(d_name)
if res!="null":
result = check_line(res,findstr)
if result=="null":
print("此手机号性别未知")
elif result.find("男") != -1:
print("此手机号性别男")
elif result.find("女") != -1:
print("此手机号性别女")
if __name__=="__main__":
main()
主要代码就是上面的，
getDevicesAll函数获取所有连接电脑的usb手机设备，拿到设备名字
export函数获取当前连接的手机的页面
check_line函数拿到准确的一行，拿不到说明是未知性别
main函数进行逻辑判断等
我提供的主要是思路以及主要代码。
那些adb输入手机号，点击搜索，返回，重新搜索一系列操作都很简单，
就不啰嗦了。还有很多设备同时搜索控制进行识别手机号等，需要你们自己完成。
不过主要代码已经在上面了。你们进行自己定制更改即可。
对了，有的电脑上可能没有adb工具，百度一下adb安装等字眼，配置一下就好了。
