如何在Appium1.7中使用longPress？

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.TouchAction;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.remote.MobileCapabilityType;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;

import java.net.MalformedURLException;
import java.net.URL;

public class AppiumLongPressExample {
    public static void main(String[] args) throws MalformedURLException {
        // 设置DesiredCapabilities对象
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
        capabilities.setCapability(MobileCapabilityType.PLATFORM_VERSION, "9.0");
        capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, "Android Emulator");
        capabilities.setCapability(MobileCapabilityType.APP_PACKAGE, "com.example.app");
        capabilities.setCapability(MobileCapabilityType.APP_ACTIVITY, ".MainActivity");

        // 创建AppiumDriver对象
        AppiumDriver<WebElement> driver = new AndroidDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

        // 定位元素
        WebElement element = driver.findElementById("com.example.app:id/button");

        // 创建TouchAction对象
        TouchAction action = new TouchAction(driver);

        // 执行长按操作
        action.longPress(element).perform();

        // 执行其他操作
        // ...

        // 关闭驱动
        driver.quit();
    }
}
