@AndroidFindBy(xpath = "//android.widget.EditText[@text='Email']")
public AndroidElement edt_email_login;

@AndroidFindBy(xpath = "//android.widget.EditText[@text='Password']")
public AndroidElement edt_password_login;

@AndroidFindBy(xpath = "//android.widget.EditText[@text='Login']")

推荐答案

既然你在使用 Appium，那么你有可以使用的 AppiumDriver 或 AndroidDriver 实例吗?

Since you are using Appium, do you have an AppiumDriver or AndroidDriver instance you can use?

而不是使用 @AndroidFindBy(xpath = "//android.widget.EditText[@text='Password']")public AndroidElement edt_password_login;，我建议尝试一些更简单的方法，例如:

Rather than use @AndroidFindBy(xpath = "//android.widget.EditText[@text='Password']") public AndroidElement edt_password_login;, I would recommend trying something a little more simple, like this:

private class Selectors
{
    public static readonly By Password = By.XPath("//android.widget.EditText[@text='Password'];

    public static readonly By Email = By.XPath("//android.widget.EditText[@text='Email']");

}

这解决了对@AndroidFindBy 的需求，我认为这可能是这里抛出错误的原因.您可以使用驱动程序定位您的元素:

This works around the need for @AndroidFindBy, which I think is what may be throwing the error here. You can locate your elements using the driver:

driver.findElement(Selectors.Email);driver.findElement(Selectors.Password);
