Error while trying out touch actions using Appium

问题

Below is my code:

package AppiumPackage;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.interactions.touch.TouchActions;
import org.openqa.selenium.remote.Augmenter;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.Assert;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;
import io.appium.java_client.remote.MobileBrowserType;
import io.appium.java_client.remote.MobileCapabilityType;
import io.appium.java_client.service.local.AppiumDriverLocalService;

import java.net.MalformedURLException;
import java.net.URL;
import java.util.List;

public class AppiumClass {
    AppiumDriver driver;
    WebDriverWait wait;
    String AppURL = "https://www.ndtv.com/";

    @BeforeTest
    public void setup() throws MalformedURLException {

        // Create an object for Desired Capabilities
        DesiredCapabilities capabilities = new DesiredCapabilities();

        capabilities.setCapability("chromedriverExecutable", "C:/Users/Madankumar/Desktop/Chrome Driver/chromedriver.exe");

        // Name of mobile web browser to automate. ‘Safari’ for iOS and ‘Chrome’
        // or ‘Browser’ for Android
        //capabilities.setCapability("browsername", "Chrome");
        capabilities.setCapability(MobileCapabilityType.BROWSER_NAME,MobileBrowserType.CHROME);

        // The kind of mobile device or emulator to use - iPad Simulator, iPhone
        // Retina 4-inch, Android Emulator, Galaxy S4 etc
        capabilities.setCapability("deviceName", "919d8316");

        // Which mobile OS platform to use - iOS, Android, or FirefoxOS
        capabilities.setCapability("platformName", "Android");

        // Java package of the Android app you want to run- Ex:
        // com.example.android.myApp
        capabilities.setCapability("appPackage", "com.android.chrome");

        // Activity name for the Android activity you want to launch from your
        // package
        capabilities.setCapability("appActivity", "com.google.android.apps.chrome.Main");
        capabilities.setCapability("autoAcceptAlerts", false);

        // Initialize the driver object with the URL to Appium Server and
        // passing the capabilities
        driver = new AppiumDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities);
        wait = new WebDriverWait(driver, 5);
    }

    @Test
    public void testSearchAppium() throws Throwable {

        driver.get(AppURL);
        Thread.sleep(2000);
        driver.findElement(By.xpath("//a[@class='notnow']")).click();
        Thread.sleep(2000);
        TouchActions actions=new TouchActions(driver);
        actions.longPress(driver.findElement(By.xpath("//a[@class='scroll__nav-link active-nav']"))).perform();
        Thread.sleep(3000);
        actions.flick(20, 0);


    }    

    /*
    @AfterTest
    public void tearDown() {
        driver.quit();
    }
    */

}

On running the class from Eclipse IDE getting below error:

回答1:

TouchAction class related to Appium JAVA Client jar,not related to selenium.

Remove import org.openqa.selenium.interactions.touch.TouchActions package and import Appium JAVA Client jar.

Do your code like this :

public void testSearchAppium() throws Throwable 
{ 
   driver.get(AppURL); 
   Thread.sleep(2000); 
   MobileElement notNow=driver.findElement(By.xpath("//a[@class='notnow']"));  
   TouchAction actions=new TouchAction((PerformsTouchActions) driver); 
   actions.tap(notNow).perform(); 
}

回答2:

The working solution for this issue is in the following link.

ClassCastException with new Appium-java TouchActions

Re-writing the solution here again

Use io.appium.java_client.TouchAction class.

Step 1

TouchAction action = new TouchAction(driver);

Here driver is an instance of AppiumDriver.

Step 2

WebElement ele = driver.findElement(By.id("locator"));

action.tap(new TapOptions().withElement(new ElementOption().withElement(ele))).perform();

With the new implementation of TouchAction you cannot directly pass weblement.

dependency used

<dependency>
    <groupId>io.appium</groupId>
    <artifactId>java-client</artifactId>
    <version>7.0.0</version>
</dependency>

Hope it helps.
