问题描述
在将我的问题标记为重复之前，请理解我已经遵循了关于stackoverflow的所有类似主题，包括：
org.openqa.selenium.NoSuchElementException: no such element
How to resolve org.openqa.selenium.NoSuchElementException in Selenium?
org.openqa.selenium.NoSuchElementException
org.openqa.selenium.NoSuchElementException Cannot find textbox element.
但是，尽管尝试了2天，我仍然无法解决该问题。
我将Eclipse与TestNG，Appium和uiautomatorviewer一起使用，以查看我的应用程序的布局详细信息。
这是我的基类代码：
public class BaseClass {
static AppiumDriver<MobileElement> driver;
@BeforeTest
public void setup() throws Exception
{
DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability(MobileCapabilityType.PLATFORM_NAME,"ANDROID");
caps.setCapability(MobileCapabilityType.PLATFORM_VERSION,"7.1.2");
caps.setCapability(MobileCapabilityType.DEVICE_NAME,"Redmi");
caps.setCapability(MobileCapabilityType.UDID,"6f13c427d440");
caps.setCapability("appPackage","com.example.shipmart");
caps.setCapability("appActivity","com.example.shipmart.MainActivity");
caps.setCapability("autoGrantPermissions",true);
caps.setCapability(MobileCapabilityType.APP,"C:\\Users\\Sparsh\\eclipse-workspace\\meriArt\\src\\test\\resources\\apps\\meri.apk" );
caps.setCapability("automationName","uiautomator2");
URL url = new URL("http://localhost:4723/wd/hub");
driver = new AppiumDriver<MobileElement>(url,caps);
}
@AfterSuite
public void teardown()
{
driver.close();
driver.quit();
}
}
这是我的TestNG测试类代码：
public class Tests extends BaseClass {
@Test
public void testOne()
{
driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);
MobileElement etSalary =driver.findElement(By.id("com.example.shipmart:id/etSalary"));
etSalary.setValue("45555"); //THIS WORKS FINE
MobileElement btnGo =driver.findElement(By.id("com.example.shipmart:id/btnGo"));
//EXCEPTION OCCURS IN ABOVE LINE
btnGo.click();
System.out.println("ID of ImageButton is: " + btnGo.getId());
}
}
第一个元素“ etSalary”已被检测到并填充有提供的值，但是在尝试找到第二个元素btnGo时发生异常。
这是完整的错误消息：
org.openqa.selenium.NoSuchElementException: An element Could not be located on the page using the given search parameters.

我尝试使用wait，使用xpath，类名，content-desc等来定位元素，将Java 10降级为Java 8，但我无法解决问题。
请帮助！
解决方法
可能会有多种情况显示此异常。
- 在上一个元素中发送键时，它是否在屏幕上？
- 如果将其发送给prev元素后将其启用或可见，则应使用显式等待来处理。或者，您可以尝试在找到buttongo元素之前添加睡眠。
- 按钮go元素可能位于屏幕上不可见，可能是因为您需要滚动Android页面并转到该元素。
希望这对您有所帮助。
