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

Question

大家好社区：我正在 Android 中使用移动应用程序。

我尝试向下滑动（滚动）到应用程序的最后，但这是不可能的。类似的情况我在论坛里红过很多次，但都帮不了我。

下面是我的技术堆栈。

Appium version: 1.17.1
Java: 1.8

这是我的 POM 文件。

我为此尝试使用的方法：

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();
    }

我一次又一次收到下一个错误：

java.lang.NullPointerException

有人能帮帮我吗？

Answer 1

您还需要在 hashmap 中添加元素以向上或向下滑动页面。 Appium 将保留该元素并滑动 up/down.
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

以上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();

不好的是滑动很慢
