python编写adb截图工具的实现源码

一、 功能

Android端或者Android终端的远程截图至本地电脑中

在这里插入图片描述

二、使用说明

1.adb截图工具可用于Android手机及Android终端
2.使用数据线连接前提:电脑与Android终端/手机已连接
Android终端/手机已打开开发者模式
3.生成的图片格式为png

三、实现

1.初始源码

import time
import os,sys

#截图
def screencap_cmd(filePath,devices=None):
    if filePath==None:
        filePath='D:/png/'
    if not os.path.exists(filePath):
        os.makedirs(filePath)
    filename=time.strftime("%Y%m%d%H%M%S",time.localtime())+".png"
    if devices==None:
        cmd_screencap='adb shell screencap -p sdcard/'+filename
        cmd_pull='adb pull sdcard/'+filename+' '+filePath+filename
        cmd_delete='adb shell rm sdcard/'+filename
    else:
        cmd_screencap='adb -s '+devices+' shell screencap -p sdcard/'+filename
        cmd_pull='adb -s '+devices+' pull sdcard/'+filename+' '+filePath+filename
        cmd_delete='adb -s '+devices+' shell rm sdcard/'+filename
    os.system(cmd_screencap)
    os.system(cmd_pull)
    os.system(cmd_delete)
#保存地址判断及设备信息分类调用
def screencap_info(devices=None,filePath=None):
    if filePath==None:
        filePath='D:/png/'
    if not os.path.exists(filePath):
        os.makedirs(filePath)
    if devices==None:
        screencap_cmd(filePath)
        adb_device_none(filePath)
    else:

    for i in lines:
        if devices in i:
            return devices
    print("未找到改设备请重新输入!")
    change_devices()
#截图命令判断,电脑连接多个设备或使用IP截图时
def adb_info(lines,filePath=None):    
    s=input("是否截图(T/F/N)?\n")
    if s=='t' or s=='T':
        if filePath==None:
            screencap_info(lines)
        else:
            screencap_info(lines,filePath)
    elif s=='N' or s=='n' or s=='exit':
        sys.exit()
    elif s=='F' or s=='f':
        devices=change_devices()
        if filePath==None:
            adb_info(devices)
        else:
            adb_info(devices,filePath)    
 #截图命令判断,电脑连接仅连接一个设备时  
def adb_device_none(filePath=None):
    s=input("是否截图(T/F/N)?\n")
    if s=='t' or s=='T':
        if filePath==None:
            screencap_info()
        else:
            screencap_info(None,filePath)
    elif s=='N' or s=='n' or s=='exit':
        sys.exit()
    elif s=='F' or s=='f':
        devices=change_devices()
        if filePath==None:
            adb_info(devices)
        else:
            adb_info(devices,filePath)
#使用设备判断
def adb_devices(n,lines,filePath=None):
    if n==0:
        print("请检查是否已接连或启动调试模式或安装adb环境")
        s=input("再次启动(T/F)?\n")
        if s=='t' or s=='T':
            r=os.popen("adb devices")
            lines=r.readlines()
            lines=lines[1:-1]
            n=len(lines)
            adb_devices(n,r.readlines())
        else:
            sys.exit()
    elif ":5555" in lines:
        print("T:截图  F:更换设备 exit|N:退出 ")
        if filePath==None:
            adb_info(lines)
        else:
            adb_info(lines,filePath)   
    elif n==1:
        print("T:截图  F:更换设备  exit|N:退出")
        if filePath==None:
            adb_device_none()
        else:
            adb_device_none(filePath)    
    elif n>1:
        for i in lines:
            print(i.split("\t")[0])
        devices=input("请输入指定设备:\n")
        for i in lines:
            if devices in i:
                print("T:截图  F:更换设备  exit|N:退出")
                if filePath==None:
                    adb_info(devices)
                else:
                    adb_info(devices,filePath)  
        print("未找到改设备请重新输入!")
        if filePath==None:
            adb_devices(n,lines)
        else:  
            adb_devices(n,lines,filePath)

#输入IP
def ip_info():
    ipPath=input("请输入IP:(不输入enter跳过默认使用数据线连接)\n")
    if len(ipPath)>0:
        try:
            cnd='adb connect '+ipPath
            os.system(cnd)
            return ipPath
        except:
            print("ADB调试模式为USB,需要切换到无线调试模式\n")
            print("切换方法:\n第一步:Android设备开启USB调试,并且通过USB线连接到电脑\n第二步:在终端执行以下命令”adb tcpip 5555“\n第三步:在终端执行以下命令”adb connect ip“。此时拔出USB线,应该就可以adb通过wifi调试设备\n")
            return ip_info()
if  __name__ == '__main__':
    ipPath=ip_info()
    filePath=input("请输入保存地址:(不输入enter跳过,默认保存至D:\png\)\n")
    #查询当前连接的设备
    r=os.popen("adb devices")
    lines=r.readlines()
    lines=lines[1:-1]
    n=len(lines)
    ip_add=0
    if ipPath!=None:
        for i in lines:
            if ipPath in i:
                ip_add=i.split("\t")[0]
    if len(filePath)>0:
        if ":\\" in filePath:
            if ip_add!=0:
                adb_devices(n,ip_add,filePath)
            else:
                adb_devices(n,lines,filePath)
        else:
            print("地址输入非法,使用默认地址\n")
            if ip_add!=0:
                adb_devices(n,ip_add)
            else:
                adb_devices(n,lines)
    else:
        if ip_add!=0:
            adb_devices(n,ip_add) 
        else:
            adb_devices(n,lines) 

2.优化:增加ip连接断开重连处理

在输入ip函数ip_info()增加ip连接判断,将os.system替换成os.popen函数执行cmd命令:

r=os.popen(cnd)
#读取执行结果
lines=r.readlines()[0]
if 'unable' in lines:
    print("连接失败\n")
    return ip_info()
else:
    return ipPath
  1. os.system函数无法获取执行结果,只能获取执行成功或失败的结果,成功返回0,失败返回1,且会执行的结果打印在终端上,相当于调起dos执行命令
  2. os.popen函数可获取执行的结果内容,但获取的结果要进行readlines读取,执行的结果不会打印在终端上

在输入ip函数ip_info()增加ip连接判断,将os.system替换成os.popen函数执行cmd命令:

a=os.system(cmd_screencap)
if a==0:
   os.system(cmd_pull)
   os.system(cmd_delete)
else:
   if ":5555" in devices:
            print("连接断开,请重新连接\n")
            ipPath=ip_info()
            if ipPath==None:
                ipPath=ip_info()
            else:
                device=ipPath+":5555"
                adb_info(device,filePath)
        else:
            print("设备连接断开,请更换设备\n")
            device=change_devices()
            adb_info(device,filePath)

3.最终源码

    ipPath=input("请输入IP:(不输入enter跳过默认使用数据线连接)\n")
    if len(ipPath)>0:

            r=os.popen(cnd)

            if 'unable' in lines:
                print("连接失败\n")
                return ip_info()
            else:
