博客给出了Android的KeyBoardUtil工具类代码。该类包含显示键盘、隐藏键盘和判断键盘是否显示的静态方法，通过InputMethodManager实现相关功能，可用于Android开发中对键盘的操作控制。

public final class KeyBoardUtil {
    public KeyBoardUtil() {
    }

    public static void showKeyBoard(Context context, EditText editText) {
        InputMethodManager inputMethodManager = (InputMethodManager)context.getSystemService("input_method");
        inputMethodManager.showSoftInput(editText, 2);
        inputMethodManager.toggleSoftInput(2, 1);
    }

    public static void hideKeyBoard(Activity context) {
        View view = context.getCurrentFocus();
        if(view != null) {
            InputMethodManager inputMethodManager = (InputMethodManager)context.getSystemService("input_method");
            inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 2);
        }

    }

    public static boolean isShownKeyBoard(Activity activity) {
        View view = activity.getWindow().peekDecorView();
        if(view == null) {
            return false;
        } else {
            InputMethodManager inputMethodManager = (InputMethodManager)activity.getSystemService("input_method");
            return inputMethodManager.isActive() && activity.getWindow().getCurrentFocus() != null;
        }
    }
}
