如何在appium中使用longpress？

import io.appium.java_client.TouchAction;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;
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Desired Capabilities
        DesiredCapabilities caps = new DesiredCapabilities();
        caps.setCapability("platformName", "Android");
        caps.setCapability("deviceName", "Android Emulator");
        caps.setCapability("appPackage", "com.example.app");
        caps.setCapability("appActivity", ".MainActivity");

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

        // 执行长按操作
        TouchAction action = new TouchAction(driver);
        action.longPress(element).perform();

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