修改方法

（一）在actions包中添加一个EasyScreenshotAction类

顾名思义，就是一个方便的快照类

代码如下

}

（二）在UiAutomatorViewer类中，添加一个按钮

代码如图所示

（三）打一个jar包，替换原来的uiautomatorviewer.jar文件即可

实现原理

避免了原版uiautomatorviewer使用socket通信，降低的通信成本。

直接利用adb命令进行截图和dump，将图片和xml dump文件自动传到电脑端（自动创建C:\TempForUiautomatorView目录）

同时建立线程池，多线程执行数条adb指令，也能缩短快照时间

最终在电脑端对文件进行解析，获得控件树
