在之前的第一篇文章：
android自动化测试中hierarchyviewer和uiautomatorviewer获取控件信息的方式比对（1）
我说uiautomatorviewer获取动态的界面会报错。错误如下：
今天我学习uiautomator的时候，用dumpWindowHierarchy()获得控件信息的时候，发现这个方法可以得到动态的界面信息。这就弥补了uiautomatorviewer的缺陷。下面把过程给大家贴出来。
如何编写java工程文件的信息，前辈们写了很多，我把我学习的连接放给大家。
http://blog.csdn.net/robinzhou/article/details/8447058
我捡主要的将。java代码：
package com.ibm.test;import java.io.File;import com.android.uiautomator.core.UiDevice;import com.android.uiautomator.core.UiObjectNotFoundException;import com.android.uiautomator.testrunner.UiAutomatorTestCase;public class MyUIauto extends UiAutomatorTestCase { private static final String TAG = "MyUIauto"; public void testPressHome() throws UiObjectNotFoundException { File file = new File("/data/local/tmp/local/tmp/qian.xml"); UiDevice uiDevice = getUiDevice(); //uiDevice.pressHome(); String realPath = "qian.xml"; uiDevice.dumpWindowHierarchy(realPath); }}我看了一下dumpWindowHierarchy的方法源码：
public void [More ...] dumpWindowHierarchy(String fileName) { AccessibilityNodeInfo root = getAutomatorBridge().getQueryController().getAccessibilityRootNode(); if(root != null) { AccessibilityNodeInfoDumper.dumpWindowToFile( root, new File(new File(Environment.getDataDirectory(), "local/tmp"), fileName)); } }官网上的说明默认目录是/data/local/tmp目录，但从源码上可以看见它又增加了local/tmp目录。合并起来就是/data/local/tmp/local/tmp目录。这也是我起先随便建立个目录造成的错误的原因，老是报/data/local/tmp/local/tmp/下无文件的错误。后来找到源码才知道。源码网站给大家：
http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.1.2_r1/com/android/uiautomator/core/UiDevice.java#UiDevice.dumpWindowHierarchy%28java.lang.String%29
编写完java工程 以后，用ant命令生成jar包，然后把jar包push到设备上，将秒表打开。然后运行脚本，得到xml文件，抓到本地。查看xml文件如下：

所以，这个方式才是获得控件的最佳方法。
