C# 检测Android自定义键盘中的isSticky

我有一个自定义键盘，上面的按钮已启用isSticky，但我无法检测它是否打开或关闭（真/假），并且在按下任何键（如果打开）（真）后也无法禁用它们

问题是我找不到一种方法来检测按键，也无法将当前的edittext附加到函数中（所有的粘性按钮都有特定的函数）

这应该发生在OnKey函数中

这是我的键盘课：

public class MyKeyboardListener : Java.Lang.Object, KeyboardView.IOnKeyboardActionListener{

    private readonly Activity _activity;

    public MyKeyboardListener(Activity activity){
        _activity = activity;
    }

    public void OnKey(Android.Views.Keycode primaryCode, Android.Views.Keycode[] keyCodes){
        var eventTime = DateTime.Now.Ticks;
        var keyEvent = new KeyEvent(eventTime, eventTime, KeyEventActions.Down, primaryCode, 0);

        switch ((int)primaryCode) {
            case 1005:
            break;

            case 1006:
            break;

            default:
                _activity.DispatchKeyEvent(keyEvent);
            break;
        }
    }

    public void OnPress(Android.Views.Keycode primaryCode){
    }

    public void OnRelease(Android.Views.Keycode primaryCode){
    }

    public void OnText(Java.Lang.ICharSequence text){
    }

    public void SwipeDown(){
    }

    public void SwipeLeft(){
    }

    public void SwipeRight(){
    }

    public void SwipeUp(){
    }
}

方法，并使用以下代码获取粘滞键和修改键

List<Key> keys = getKeyboard().getKeys();
for (Key key : keys) {
    Drawable npd;
    // int drawable = R.drawable.btn_normal_with_shadow_t1;
    int drawable = R.drawable.key_normal;
    textColor = sessionManager.getSimpleyKeyTextColor();

    if (key.pressed) {
        drawable = R.drawable.key_normal;
    } else {
        if (key.modifier && key.sticky) {
            drawable = R.drawable.stickey_with_shad_bord;
            textColor = sessionManager.getSimpleyKeyTextColorModifiers();
        } else if (key.modifier) {
            drawable = R.drawable.modifier_btn_with_bord_shad;
            textColor = sessionManager.getSimpleyKeyTextColorModifiers();
        } else {
