Question

Appium版本为1.9.0 Java客户端版本为1.6.1 Android Studio版本3.2 chrome驱动程序版本为 ChromeDriver 2.42 Android移动设备Chrome浏览器版本为69.0，而Android版本为6.0

以下是我尝试切换子窗口的代码

Set<String> windows = driver.getWindowHandles(); // Get all windows working fine

String parentWindow = windows.stream().findFirst().get(); // Get parent window 

Thread.sleep(15000); // Adding static time due to page loading issue

driver.switchTo().window(windows.toArray()[windows.toArray().length-1].toString());

切换到子窗口。也windows.toArray([windows.toArray().length-1].toString()给出正确的值，但如果将其放在driver.switchTo.window上，则会抛出异常以下的情况

例外

Answer 1

您可以尝试使用stream API

driver.switchTo().window(windows.stream().skip(windows.size()- 2).findFirst().get());

Answer 2

您可以尝试一下吗？

String childWindow = (String) windows.toArray()[windows.toArray().length-1];
driver.switchTo().window(childWindow);

通过使用driver.switchTo（）。window（）在appium中切换窗口，它会提供org.openqa.selenium.WebDriverException
