其实就是获得当前打开的窗口的packageName/activityName，输出与HierarchyViewer工具检测到的信息一致，所以猜想其用到同样的方法。

输出：

'''     public boolean visible(ViewNode node)       * Gets the visibility of a given element.      * @param selector selector for the view.      * @return True if the element is visible. ''' isVisible = viewer.visible(button) print "is visible:",isVisible
