在应用程序中滑动后无法单击元素

Question

我在亚马逊购物应用上测试过。我有一个问题后滑动找到一个元素。因为列表视图太长了。我需要滚动（使用刷卡API）。但是在我滑动之后，我不能再点击元素了。它没有返回错误，但应用程序没有响应。

函数ScrollToElement（）用于滑动到搜索元素。我试着用触控动作轻拍，但没有希望。我试图找到一个准确的（372466）位置，但效果并不理想。提前谢谢。

      String appActivityText = "com.amazon.mShop.home.HomeActivity";


      String appPackageText = "in.amazon.mShop.android.shopping";

      File classpathRoot = new File(System.getProperty("user.dir"));

      // Find swipe start and end point from screen's with and height.
      // Find starty point which is at bottom side of screen.
      int start = (int) (size.height * 0.20);
      int starty = (int) (size.height * 0.80);

      int endy = (int) (size.height * 0.20);
      // Find horizontal point where you wants to swipe. It is in middle of
      // screen width.
      int startx = size.width / 2;

      while (true) {
         driver.swipe(startx, starty, startx, endy, 3000);
         start = start + (starty - endy);
         if (element.getLocation().getY() - start < size.height - endy) {
            break;
         }
      }
   }
}

Answer 1

代码的问题是错误地使用了driver.findElement。让我解释一下。driver.find元素检查屏幕上显示的元素，如果找到，它将返回它。

代码的问题是在滚动功能之前执行了driver.findElement，这意味着如果元素当前不在屏幕上，测试将始终失败。

这个代码块应该可以帮助您：

public WebElement findItemWithScrollingUsingBy(By by, int interactions) {
    for (int i = 0; i < interactions; i++) {
        if (driver.findElements(by).size() == 0) {
            scrollDown();
        } else {
            return driver.findElement(by); //you can add .click() here instead of returning the element
        }
    }
    Assert.fail("Element not found");
    return null;
}

函数scrollDown（）只是将刷卡的代码块转移到一个外部函数，这样就更干净了。

总结一下我的回答：

1. 在屏幕上搜索元素-如果找到，请单击
2. 如果未找到-执行另一个滚动操作并再次搜索元素
3. 重复
