使用 Xpath 找不到 WebElement

Question

I find the element with By.id, as the following code:我找到带有By.id的元素，如下代码：

element = driver.findElement(AppiumBy.id(
    "com.test:id/product_detail_nav_host"
));

But none of this lines can find the same element:但是这些行都找不到相同的元素：

element = driver.findElement(AppiumBy.xpath(
    "//*[id='com.test:id/product_detail_nav_host']"
));

element = driver.findElement(AppiumBy.xpath(
    "//*[@id='com.test:id/product_detail_nav_host']"
));

element = driver.findElement(AppiumBy.xpath(
    "//*[resource-id='com.test:id/product_detail_nav_host']"
));

Answer 1

The first xpath is errorprone as you are missing the @ before the keyword id第一个xpath 容易出错，因为您在关键字id之前缺少@

The third xpath is also errorprone as the value第三个xpath也是容易出错的值

com.test:id/product_detail_nav_host

is of the id attribute, but not the resource-id attribute.是id属性，但不是resource-id属性。

However, the second code block looks flawless to me and should work perfecto:然而，第二个代码块在我看来完美无缺，应该可以完美运行：

element = driver.findElement(AppiumBy.xpath(
    "//*[@id='com.test:id/product_detail_nav_host']"
));
