driver.findElements(By.xpath("//text[@text='OS']"))
这个应该是找到的.

你可以试试 driver.findElements(By.xpath("//text")) 打印下找到的每个元素的 text 是多少

还是找不到
#1 楼 @seveniruby

driver.findElements(By.xpath("//text[@text='OS']")).size();
//String strtest = testList.get(0).getAttribute("text");
driver.findElements(By.xpath("//text")).size(); 

由于两个 size（）都是 0，所有中间那行报错。是不是我的设备还是环境版本有问题，XPath 没有一个成功的。

如下是全部的代码，i 都是=0，XPath 在我的代码里面没有成功获取过

#2 楼 @nearlynie 你的版本号是多少, 你试试其他的几种定位方式. 比如 uiautomator 先确认下其他的定位方式是否可以. 最新版本的 appium 我还没有进行全面的测试.

问题已解决 谢谢

#5 楼 @nearlynie 啥问题造成的呢？

#6 楼 @purpose 你可以下载最新的 appium 版本试试效果
