我在下面的链接中附加了Jave代码，错误日志，Appium错误日志和屏幕截图。
测试代码：
public static void main(String[] args ) throws MalformedURLException{
WebDriver driver;
//Set up desired capabilities and pass the Android app-activity and app-package to Appium
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("BROWSER_NAME","Android");
capabilities.setCapability("VERSION","7.0");
capabilities.setCapability("deviceName","ZY223ZMPG6");
capabilities.setCapability("platformName","Android");
capabilities.setCapability("noReset","false");
capabilities.setCapability("appPackage","com.equationswork.kinghoo");
// This package name of your app (you can get it from apk info app)
capabilities.setCapability("appActivity","com.equationswork.kinghoo.MainActivity"); // This is Launcher activity of your app (you can get it from apk info app)
//Create RemoteWebDriver instance and connect to the Appium server
//It will launch the App in Android Device using the configurations specified in Desired Capabilities
driver = new RemoteWebDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities);
//locate the Text on the by using By.id()
driver.manage().timeouts().implicitlyWait(4, TimeUnit.SECONDS);
driver.findElement(MobileBy.id("com.android.packageinstaller:id/permission_allow_button")).click();
driver.findElement(MobileBy.id("com.android.packageinstaller:id/permission_allow_button")).click();
driver.findElement(MobileBy.id("com.android.packageinstaller:id/permission_allow_button")).click();
driver.findElement(MobileBy.id("com.android.packageinstaller:id/permission_allow_button")).click();
driver.findElement(By.xpath("//android.view.View[@index='0']/android.widget.EditText[@index='0']")).sendKeys("san.kktikam@eab.com");
driver.findElement(By.xpath("//android.view.View[@index='1']/android.widget.EditText[@index='0']")).sendKeys("A3DGURK7");
driver.findElement(By.id("btnLogin")).click();
}

答案 0 :(得分：1)
我认为你先检查你的Xpath是否存在。为此我写了一个功能很好的函数。试试这个功能。
public static String checkpathispresent(String strXpath)
{
try
{
String lead;
Object elem = driver.findElementByXPath(strXpath);
if(elem.equals(null))
{
lead="";
System.out.println(strXpath+ "has no value so setting blank.");
}
else
{
lead = driver.findElementByXPath(strXpath).getText();
System.out.println("lead is "+lead);
}
return lead;
}catch(Exception ex)
{
System.out.println("Xpath do not exist");
return "";
}
}
另外针对您的问题尝试使用此xpath - “//android.view.View[@index='2']/android.view.View[@index='0']/android.widget.EditText[@index='0']”你的Xpath必须是唯一的这样它就可以访问，不会与其他元素的Xpath冲突。在您的情况下，索引2的视图根据您的屏幕截图具有0-8内部视图。
