现在使用 appium 做 android 的自动化测试, 连接的是 android 真机, driver 使用的是 WebDriver. 发现 WebDriver 本身自带的方法非常有限.不像 AndroidDriver 有现成的 swipe(startx, starty, endx, endy, duration);和 tap(fingers, x, y, duration);方法.
我想请教各位以下问题:

1. 如何实现对坐标点的单击, 双击, 长按, 拖拽操作?

2. 当前页面没有显示的控件, 如何实现拖拽去找到指定的控件?
   我下面贴一下我的代码:

   package appium;
   import java.net.URL;
   import java.util.concurrent.TimeUnit;
   import org.openqa.selenium.By;
   import org.openqa.selenium.WebDriver;
   import org.openqa.selenium.WebElement;
   import org.openqa.selenium.remote.DesiredCapabilities;
   import org.openqa.selenium.remote.RemoteWebDriver;
   import org.testng.Assert;
   import org.testng.annotations.AfterMethod;
   import org.testng.annotations.BeforeMethod;
   import org.testng.annotations.Test;
   public class sdk_COOLPAD {
   private WebDriver driver;
   SDK sdk = new SDK("COOLPAD");
   @BeforeMethod(alwaysRun = true)
   public void setUp() throws Exception {
       DesiredCapabilities capabilities = new DesiredCapabilities();
       capabilities.setCapability("platformName", "Android");
       capabilities.setCapability("deviceName", "vivo x5l");
       capabilities.setCapability("udid", "BMBY8LU4YTMBS8SO");
       capabilities.setCapability("app", sdk.getApk());
       capabilities.setCapability("appPackage", sdk.getPkg());
       capabilities.setCapability("appActivity", sdk.getActivity());
       capabilities.setCapability("unicodeKeyboard", true);
       capabilities.setCapability("resetKeyboard", true);
       driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
   }
   
   @AfterMethod(alwaysRun = true)
   public void tearDown() throws Exception {
       driver.quit();
   }
   
   @Test(groups = { "testCOOLPAD" })
   public void testCOOLPAD() throws InterruptedException {
       driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
       driver.findElement(By.xpath("//android.widget.Button[contains(@text,'初始化SDK')]")).click();
       Assert.assertTrue(((WebElement) driver.findElement(
               By.xpath("//android.widget.RelativeLayout/android.widget.LinearLayout/android.widget.TextView[2]")))
                       .getText().contains("初始化成功"));
       driver.findElement(By.xpath("//android.widget.Button[contains(@text,'清空')]")).click();
       driver.findElement(By.xpath("//android.widget.Button[contains(@text,'获取网关')]")).click();
       Assert.assertTrue(((WebElement) driver.findElement(
               By.xpath("//android.widget.RelativeLayout/android.widget.LinearLayout/android.widget.TextView[1]")))
                       .getText().contains("获取网关成功"));
       driver.findElement(By.xpath("//android.widget.Button[contains(@text,'清空')]")).click();
       driver.findElement(By.xpath("//android.widget.Button[contains(@text,'登录（第一步）')]")).click();
       driver.findElement(By.xpath("//android.widget.EditText[contains(@text,'请输入手机号/邮箱')]"))
               .sendKeys(sdk.getAccount());
       driver.findElement(By
               .xpath("//android.widget.ScrollView/android.widget.RelativeLayout/android.widget.RelativeLayout/android.widget.LinearLayout/android.widget.RelativeLayout[2]/android.widget.EditText"))
               .sendKeys(sdk.getPwd());
      //此时, 当前页面并没有显示登录按钮, 需要对屏幕进行上拉操作才能找到并点击登录按钮
       driver.findElement(By.xpath("//android.widget.TextView[contains(@text,'登   录')]")).click();
   }
   }
