Question

我在移动Native App中滚动时遇到问题，我在用： Java语言 Java客户端1.7.0 appium节点1.13.0 操作系统版本Android AND Appium驱动程序

，并尝试在进入“个人资料”页面后滚动，但出现了一些应用崩溃的情况。

我正在使用以下Methode进行滚动：

public void scrollDown() {
    Dimension dimension = driver.manage().window().getSize();
    // System.out.println("Dimension value = "+dimension);

    Double scrollHeightStart = dimension.getHeight() * 0.5;
    int scrollStart = scrollHeightStart.intValue();
    // System.out.println("Screen Height start Value="+scrollHeightStart);

    Double scrollHeightEnd = dimension.getHeight() * 0.2;
    int scrollEnd = scrollHeightEnd.intValue();
    // System.out.println("Scroll Start Value="+scrollHeightEnd);

    TouchAction touch = new TouchAction((PerformsTouchActions) driver);
    touch.press(PointOption.point(0, scrollStart))
            .waitAction(WaitOptions.waitOptions(Duration.ofSeconds(1)))
            .moveTo(PointOption.point(0, scrollEnd))
            .release()
            .perform();
}

，但是通过调用Scroll方法运行脚本后，在Log中获得以下内容：

和.PageActions.scrollDown（PageActions.java:308）在方法scrollDown中的代码中：

尺寸标注= driver.manage（）。window（）。getSize（）;

我的假设是滚动视图不是从页面开头开始所以我必须先切换到滚动视图布局，然后才能滚动

我在注册或登录屏幕中具有相同的视图，但是首先，当我单击scrolView中的任何其他点时，例如输入电子邮件或名称，然后可以向下滚动，但是在此窗口（配置文件）中，我不能

感谢您的支持

通过使用UiAutomator和UiSelector滚动作品可以找到解决方案。

driver.findElement（MobileBy.AndroidUIAutomator（“ new UiScrollable（new UiSelector（））。scrollIntoView（new UiSelector（）。resourceId（\” <-your_resourceID->“））;”））;

通过滚动页面而崩溃
