使用UIAutomator2无法向后滚动

Question

我正在尝试使用以下代码片段向后滚动，但会引发错误

• 代码段

  try {
  
      getTLDriver().findElements(MobileBy.AndroidUIAutomator("new UiScrollable(new UiSelector()).setAsVerticalList().flingToBeginning(5);"));
  }
  catch(Exception e){
       e.printStackTrace();
  }
  

• 错误：

  org.openqa.selenium.InvalidSelectorException: Could not parse expression `new UiScrollable(new UiSelector()).setAsVerticalList().flingToBeginning(5)`: Last method called on a UiScrollable object must return a UiObject object
  

有人请帮忙

我建议使用TouchAction在Android中执行滚动，例如：

Dimension screenSize = driver.manage().window().getSize();
TouchAction action = new TouchAction((PerformsTouchActions) driver);
action.press(point(screenSize.width / 2, screenSize.height / 2))
   .waitAction()
   .moveTo(point(screenSize.width / 2, screenSize.height / 4))
   .release()
   .perform();
