Android/Java/Appium-向下滑动(滚动)不起作用[移动应用程序]

Question

嗨，社区：我正在与安卓系统中的移动应用程序作斗争。

我试着向下滑动(滚动(到应用程序的最后一页，但这是不可能的。我在论坛上有很多类似的情况，但没有什么能帮助我。

这是我下面的技术堆栈。

Appium version: 1.17.1
Java: 1.8

这是我的POM文件。

我尝试使用的方法：

public void scrollToBottom(){
JavascriptExecutor js = (JavascriptExecutor) driver;
HashMap<String, String> scrollObject = new HashMap<>();
scrollObject.put("direction", "down");
js.executeScript("mobile: scroll", scrollObject);
}
public void swipeVertical(AppiumDriver driver, double startPercentage, double finalPercentage, double anchorPercentage, int duration) throws Exception {
Dimension size = driver.manage().window().getSize();
int anchor = (int) (size.width * anchorPercentage);
int startPoint = (int) (size.height * startPercentage);
int endPoint = (int) (size.height * finalPercentage);
new TouchAction(driver).press(anchor, startPoint).waitAction((3000)).moveTo(anchor, endPoint).release().perform();
}

一次又一次我收到下一个错误：

java.lang.NullPointerException

有人能帮我吗？

Answer 1

您还需要在hashmap中添加元素来向上或向下滑动页面。Appium将按住该元素并向上/向下滑动
你可以这样做：

JavascriptExecutor js = (JavascriptExecutor) driver;
HashMap<String, String> scrollObject = new HashMap<>();
scrollObject.put("direction", "up");
scrollObject.put("element", ((RemoteWebElement) driver.findElementByAccessibilityId("id")).getId());
js.executeScript("mobile: swipe", scrollObject);

Answer 2

对于上面的依赖项，唯一有用的方法是下一个：

TouchAction action = new TouchAction(driver());
AndroidDriver<WebElement> driver = (AndroidDriver<WebElement>) driver();
int x = driver.manage().window().getSize().getWidth()/2;
int y = driver.manage().window().getSize().getHeight()/2;
action.longPress(x, y).moveTo(x, y-(y)).release().perform();

糟糕的是刷得很慢。
