如何在Appium for Android中自动执行enter键按下事件

import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidKeyCode;
import org.openqa.selenium.remote.DesiredCapabilities;

public class AppiumTest {
    public static void main(String[] args) {
        // 设置DesiredCapabilities对象，包括设备名称、App包名、App启动Activity等信息
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName", "Android Device");
        capabilities.setCapability("appPackage", "com.example.app");
        capabilities.setCapability("appActivity", ".MainActivity");

        // 创建AndroidDriver对象，连接到Appium服务器
        AndroidDriver driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

        // 执行enter键按下事件
        driver.pressKeyCode(AndroidKeyCode.ENTER);

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