如何使用appium检查android中的虚拟键盘是否打开？

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

public class KeyboardCheck {
    public static void main(String[] args) {
        // 设置Appium连接参数
        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AndroidDriver对象
        AndroidDriver<WebElement> driver = new AndroidDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

        // 检查虚拟键盘是否打开
        boolean isKeyboardOpen = driver.isKeyboardShown();
        System.out.println("Is keyboard open? " + isKeyboardOpen);

        // 关闭虚拟键盘
        if (isKeyboardOpen) {
            driver.pressKeyCode(AndroidKeyCode.BACK);
        }

        // 关闭Appium会话
        driver.quit();
    }
}
