android.accessibilityservice.AccessibilityService
继承于android四大组件之Service，其使用方式与service基本相同。但它是一个系统级别的“监听器”服务，可监听手机上所有应用所产生的小变化、大变化(比如某个被监听应用的发生的点击事件、控件文本内容变化、消息通知等)。另它有自己独立的生命周期(思路有点类似于微信公众号开发中消息与事件的处理)，如下:
onCreate()
onServiceConnected()
onAccessibilityEvent(AccessibilityEvent event)//线程阻塞式
onInterrupt()
下面进入主题：
第一步.注册服务
1.1在清单文件中注册服务
1.2meta-data引入配置
1.3accessibilityservice.xml配置信息项
1.4须手动为apk应用程序打开无障碍权限开关。
位置在设置->快捷与辅助->无障碍，找到自己的apk辅助程序应用，手动将开关打开。
第二步.实现辅助功能
思路：实现辅助功能的关键是接受到事件，并使用AccessibilityService相关api来获取应用控件信息，以及回应适当的事件，来完成"辅助"功能。
1.1下面先来看一下AccessibilityService做为"系统级"服务可以监听到指定应用的哪些事件，或者说可以监听到应用的哪些变化。
Event types支持的事件类型(全面) 1.2获取应用控件信息的方式有两种
1).通过id寻找控件，id格式为：(包名:id/+制定控件的id),对第三方应用无效。
List list = rowNode.findAccessibilityNodeInfosByViewId("com.jingyao.easybike:id/tvAmount");
2).通过控件的text寻找控件
List list = rowNode.findAccessibilityNodeInfosByText("不拼车");
1.3.可回应的事件
1)节点可回应执行的操作
android.view.accessibility.AccessibilityNodeInfo#performAction(int action)
有
android.view.accessibility.AccessibilityNodeInfo#ACTION_CLICK//节点点击 2)全局回应可执行的操作
android.accessibilityservice.AccessibilityService#performGlobalAction(int action)
有
【[Android基础]|哈罗出行自动化测试抢单测试程序】 android.accessibilityservice.AccessibilityService#GLOBAL_ACTION_BACK//后退,相当于手机后退按键
第三步.写个自动化测试DEMO应用。
