Android中是否有办法检测屏幕上是否显示软件(又称"软")键盘？

使用以沉浸式模式在客户端的应用程序上工作,使用以下代码隐藏每个活动的导航栏和状态栏:

int currentApiVersion = android.os.Build.VERSION.SDK_INT;

final int flags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_FULLSCREEN
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;

// This work only for android 4.4+
if (currentApiVersion >= 19) {

        getWindow().getDecorView().setSystemUiVisibility(flags);
        // Code below is for case when you press Volume up or Volume down.
        // Without this after pressing valume buttons navigation bar will
        // show up and don't hide
        final View decorView = getWindow().getDecorView();
        decorView
                .setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {

                    @Override
                    public void onSystemUiVisibilityChange(int visibility) {
                        if ((visibility …

目前在 Activity 类中使​​用此代码块来进入粘性沉浸模式：

override fun onWindowFocusChanged(hasFocus: Boolean) {
    super.onWindowFocusChanged(hasFocus)

    if (hasFocus && android.os.Build.VERSION.SDK_INT > 15) {
        var flags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
                View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or
                View.SYSTEM_UI_FLAG_FULLSCREEN
        flags = if (android.os.Build.VERSION.SDK_INT < 19) flags
            else flags or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
        window.decorView.systemUiVisibility = flags
    }
}

当方向切换时，状态栏会回来（甚至不是半透明的）并保持不变，直到拖动，然后再次消失。我真的不明白这种行为的原因，我该如何解决它？

先感谢您。
