如何使用appium java client 6.1.0自动化Android手机底部的Home、back、up、down、Menu按钮？

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

public class AppiumTest {
    public static void main(String[] args) {
        // 设置DesiredCapabilities
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("platformName", "Android");
        capabilities.setCapability("deviceName", "your_device_name");
        capabilities.setCapability("appPackage", "your_app_package");
        capabilities.setCapability("appActivity", "your_app_activity");

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

        // 执行自动化操作
        // ...

        // 关闭连接
        driver.quit();
    }
}

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.android.AndroidKeyCode;

public class AppiumTest {
    public static void main(String[] args) {
        // ...

        // 模拟按下Home按钮
        driver.pressKeyCode(AndroidKeyCode.HOME);

        // 模拟按下back按钮
        driver.pressKeyCode(AndroidKeyCode.BACK);

        // 模拟按下up按钮
        driver.pressKeyCode(AndroidKeyCode.DPAD_UP);

        // 模拟按下down按钮
        driver.pressKeyCode(AndroidKeyCode.DPAD_DOWN);

        // 模拟按下Menu按钮
        driver.pressKeyCode(AndroidKeyCode.MENU);

        // ...
    }
}
