6.UiWatcher API 详细介绍

public void testDemo2() throws UiObjectNotFoundException{
    //1.先注册监听器(registerWatcher(String name,UiWatcher watcher))
    UiDevice.getInstance().registerWatcher("Phone", new UiWatcher(){
        public boolean checkForCondition() {
            //1.挂断电话
            UiObject call=new UiObject(new UiSelector().text("来电"));
            UiObject view=new UiObject(new UiSelector().className("android.view.View"));
            if (call.exists()){
                System.out.print("电话监听器被触发了");              
                try{
                    view.swipeLeft(20);
                    return true;
                } catch (UiObjectNotFoundException e){
                    e.printStackTrace();
                }
            }
            return false;
        }
    });
    //1.再注册一个监听器
    UiDevice.getInstance().registerWatcher("Massage", new UiWatcher(){  
        public boolean checkForCondition() {
            System.out.print("短信监控被触发了");
            return false;
        }
    });
    //2.执行用例步骤
    //使用index+classNmae定位父类+text定位子类最终定位到对象[声音按钮]
    UiObject vol =new UiObject(new UiSelector()
    .className("android.widget.LinearLayout").index(6))
    .getChild(new UiSelector().text("声音"));
    //获取下一级界面的返回按钮
    UiObject Back=new UiObject(new UiSelector().description("声音：向上导航"));
//      //使用for循环监听器不会起作用
//      for(int i=0;i<10;i++){
//          //输出循环次数：
//          System.out.println("当前循环"+(i+1)+"次;");
//          //点击对象并等到新窗口出现
//          vol.clickAndWaitForNewWindow();
//          sleep(2000);
//          //点击返回按钮
//          Back.clickAndWaitForNewWindow();
//          sleep(2000);
//      }
    //可以在下面五次操作过程中打入电话进行调试
    //第一次点击对象并等到新窗口出现
    vol.clickAndWaitForNewWindow();
    sleep(2000);
    //点击返回按钮
    Back.clickAndWaitForNewWindow();
    sleep(2000);
    //第二次
    vol.clickAndWaitForNewWindow();
    sleep(2000);
    Back.clickAndWaitForNewWindow();
    sleep(2000);
    //第三次
    vol.clickAndWaitForNewWindow();
    sleep(2000);
    Back.clickAndWaitForNewWindow();
    sleep(2000);
    //第四次
    vol.clickAndWaitForNewWindow();
    sleep(2000);
    Back.clickAndWaitForNewWindow();
    sleep(2000);
    //第五次
    vol.clickAndWaitForNewWindow();
    sleep(2000);
    Back.clickAndWaitForNewWindow();
    sleep(2000);
    //在第五次返回后关闭指定监听器(removeWatcher(String name))这样以后就不会被触发了
    UiDevice.getInstance().removeWatcher("Phone");
    //然后再强制运行所有监控器
    UiDevice.getInstance().runWatchers();
    //第六次
    vol.clickAndWaitForNewWindow();
    sleep(2000);
    Back.clickAndWaitForNewWindow();
    sleep(2000);
    //在第五次返回后检查并输出监听器是否被触发过
    //检查是否有监听器被触发过
    boolean B=UiDevice.getInstance().hasAnyWatcherTriggered();
    //检测是否有特定监听器被触发过
    boolean Phone1=UiDevice.getInstance().hasWatcherTriggered("Phone");
    boolean Massage1=UiDevice.getInstance().hasWatcherTriggered("Massage");
    System.out.println("是否有监听器被触发过"+B);
    System.out.println("电话监听器是否被触发过"+Phone1);
    System.out.println("短信监听器是否被触发过"+Massage1);
    //逻辑判断然后进行重置和强制运行操作
    if(B==true){
        //重置被运行过的监听器
        UiDevice.getInstance().resetWatcherTriggers();
    }
