篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Android UiAutomator 快速调试相关的知识，希望对你有一定的参考价值。
背景：在Eclipse中不能直接运行Uiautomator工程，所以每次编写一份用例都要进行手动输入命令创建build文件、ant编译文件、push文件与运行测试这四步。调试起来不仅繁琐还浪费时间。网上找到一份快速调试的代码UiAutomatorHelper，可将这几步进行简化很方便。
步骤：将UiAutomatorHelper.java放到工程目录下（与测试脚本同步目录），在测试脚本中写个main方法。然后Run as ->java application即可
1 package com.change.display; 2 3 4 import java.io.IOException; 5 6 import android.os.RemoteException; 7 8 import com.android.uiautomator.core.UiDevice; 9 import com.android.uiautomator.core.UiObject; 10 import com.android.uiautomator.core.UiObjectNotFoundException; 11 import com.android.uiautomator.core.UiSelector; 12 import com.android.uiautomator.testrunner.UiAutomatorTestCase; 13 14 public class Display extends UiAutomatorTestCase{ 15 public static void main(String [] arg ){ 16 String jarName="ChangeFont"; 17 String testClass="com.change.display.Display"; 18 String testName="test1"; 19 String androidId="1"; 20 new UiAutomatorHelper(jarName, testClass, testName, androidId); 21 } 22 public void test1 () throws UiObjectNotFoundException, RemoteException, IOException{ 23 //Device wake up 24 UiDevice.getInstance().wakeUp(); 25 //sleep 3s 26 sleep(3000); 27 //Open the settings 28 Runtime.getRuntime().exec("am start -n com.android.settings/.Settings"); 29 //Click on display 30 try{ 31 UiObject display = new UiObject(new UiSelector().text("显示")); 32 display.click(); 33 sleep(3000); 34 }catch(Exception e){ 35 e.printStackTrace(); 36 } 37 //Select font 38 UiObject fs = new UiObject(new UiSelector().text("字体大小")); 39 fs.clickAndWaitForNewWindow(); 40 //Change font 41 UiObject size = new UiObject(new UiSelector().text("超大")); 42 size.click(); 43 //Screen shot 44 sleep(3000); 45 Runtime.getRuntime().exec("screencap -p /sdcard/test.png"); 46 //Enter Home interface 47 sleep(3000); 48 getUiDevice().pressHome(); 49 } 50 }
顺带附上UiAutomatorHelper.java代码
