Monkeyrunner脚本的录制与回放

　　继上一篇monkeyrunner环境搭建：http://www.cnblogs.com/zh-ya-jing/p/4351245.html 之后，我们可以进一步学习monkeyrunner了。

　　我也是刚接触monkeyrunner不久，对monkeyrunner的脚本录制功能很感兴趣，所以学习一下。没想到中间遇到很多问题，之前是录制脚本不通过，再之后是手机连接不上，monkeyrunner运行不起来，归根结底还是录制脚本的问题，后向大神请教，可算是能成功录制脚本了。

　　不知道出于什么目的，google把monkeyrunner的脚本录制功能雪藏了，需要从Android源码中才能将其发掘出来。monkey_recorder.py是用来录制在设备上的操作病生成脚本的，monkey_playback.py则用来回放脚本。

　　新建monkey_recorder.py文件，代码如下：

#!/usr/bin/env monkeyrunner

from com.android.monkeyrunner import MonkeyRunner as mr
from com.android.monkeyrunner.recorder import MonkeyRecorder as recorder

device = mr.waitForConnection()
recorder.start(device)

　　新建monkey_playback.py文件，代码如下：

#!/usr/bin/env monkeyrunner

#

# you may not use this file except in compliance with the License.

import sys
from com.android.monkeyrunner import MonkeyRunner

# The format of the file we are parsing is very carfeully constructed.
# Each line corresponds to a single command.  The line is split into 2
# parts with a | character.  Text to the left of the pipe denotes
# which command to run.  The text to the right of the pipe is a python
# dictionary (it can be evaled into existence) that specifies the
# arguments for the command.  In most cases, this directly maps to the
# keyword argument dictionary that could be passed to the underlying
# command. 

# Lookup table to map command strings to functions that implement that
# command.
CMD_MAP = {
    'TOUCH': lambda dev, arg: dev.touch(**arg),
    'DRAG': lambda dev, arg: dev.drag(**arg),
    'PRESS': lambda dev, arg: dev.press(**arg),
    'TYPE': lambda dev, arg: dev.type(**arg),
    'WAIT': lambda dev, arg: MonkeyRunner.sleep(**arg)
    }

# Process a single file for the specified device.
def process_file(fp, device):
    for line in fp:
        (cmd, rest) = line.split('|')
        try:
            # Parse the pydict
            rest = eval(rest)
        except:
            print 'unable to parse options'
            continue

        if cmd not in CMD_MAP:
            print 'unknown command: ' + cmd
            continue

        CMD_MAP[cmd](device, rest)


def main():
    file = sys.argv[1]
    fp = open(file, 'r')
    device = MonkeyRunner.waitForConnection()
    
    process_file(fp, device)
    fp.close();
    

if __name__ == '__main__':
    main()

　　连接真机或模拟器，执行以下命令：

$monkeyrunner monkey_recorder.py

执行完毕之后，monkeyrunner会打开一个窗口，如下所示。

它会不停地从设备上抓取最新界面，你可以直接在左边的屏幕截图上单击图标来模拟触控操作方式，不要直接操作真机或模拟器，否则无法录制脚本。操作的同时右边会实时显示录制的脚本，单击“Type something”按钮输入字符串，单击“Fling”按钮模拟滑动手势。当操作录制完毕后，单击“Export Actions”按钮，将脚本保存到指定目录，比如test.mr，关闭monkeyrunner运行窗口。

　　将录制好的脚本传给monkey_playback.py文件就可以回放了，执行如下命令:

$monkeyrunner monkey_playback.py test.mr

假如回放过程出错，有可能是真机或者模拟器反应比较慢，两次操作之间间隔时间太短，所以建议两次操作之间加些wait，即每次操作之后点击“wait”按钮，增加等待时间。

必须把monkey_recorder.py，monkey_playback.py和录制的脚本test.mr放入"*adt-bundle-windows-x86-20130917sdk ools"目录下，而且运行.py文件都使用绝对路径。
