在使用MonkeyRunner的时候我们经常会用到Chimchat下面的HierarchyViewer模块来获取目标控件的一些信息来辅助我们测试，但在MonkeyRunner的官网上是没有看到相应的API的描述的,上面只有以下三个类的API引用信息(http://developer.android.com/tools/help/MonkeyDevice.html)
targetDevice = MonkeyRunner.waitForConnection() ''' public ViewNode findViewById(String id) * @param id id for the view. * @return view with the specified ID, or {@code null} if no view found. ''' viewer = targetDevice.getHierarchyViewer() button = viewer.findViewById('id/title') text = viewer.getText(button) print text.encode('utf-8')
''' public ViewNode findViewById(String id, ViewNode rootNode) * Find a view by ID, starting from the given root node * @param id ID of the view you're looking for * @param rootNode the ViewNode at which to begin the traversal * @return view with the specified ID, or {@code null} if no view found. ''' iconMenuView = viewer.findViewById('id/icon_menu') button = viewer.findViewById('id/title',iconMenuView) print "Button Text:",text.encode('utf-8') ''' public static Point getAbsoluteCenterOfView(ViewNode node) * Gets the absolute x/y center of the specified view node. * * @param node view node to find position of. * @return absolute x/y center of the specified view node. */ ''' point = viewer.getAbsoluteCenterOfView(button) print "Button Absolute Center Position:",point
''' public static Point getAbsoluteCenterOfView(ViewNode node) * Gets the absolute x/y center of the specified view node. * * @param node view node to find position of. * @return absolute x/y center of the specified view node. */ ''' point = viewer.getAbsoluteCenterOfView(button) print "Button Absolute Center Position:",point
''' public String getFocusedWindowName() * Gets the window that currently receives the focus. * * @return name of the window that currently receives the focus. ''' window = viewer.getFocusedWindowName() print "Window Name:",window.encode('utf-8') 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就是查看下控件是否可见，没什么好解析的了。
