android - Appium 无法通过 content-description/accessibilityID 找到元素

Question

我一直在尝试使用 Java 获取 Appium 测试设置以在 Android 上进行测试。为了验证我的元素，我一直在使用 AndroidUiAutomator。在 UI Automator 查看器中，我可以看到可访问性标签已传播(见附图)。当我使用 findElement(By.name|By.AccessibilityId|etc 它通常只是超时，必须重新启动 Appium 服务器终端控制台才能运行测试。我使用 FindByXPath 得到类似的结果。我尝试使用超时和 waitdriver 等待确保元素已加载，但无济于事。我已经尝试了下面代码中列出的几乎所有内容。

Answer 1

您没有使用默认超时，因此如果定位器正确，appium 服务器可以获得时间来搜索元素。您应该使用显式等待来正确加载元素。

在功能中添加超时。

capabilities.setCapability("newCommandTimeout", 50);

Use these explicit wait functions based on element type if element is clickable try wait for clickable and if element is not clickable try with element’s visibility only

WebDriverWait wait = new WebDriverWait(driver, 30);

public void waitForMobileElementVisible(MobileElement element)
    {
           wait.until(ExpectedConditions.visibilityOf(element));

     }



    public void waitForMobileElementClickable(By by)
    {
            wait.until(ExpectedConditions.elementToBeClickable(by));
     }
