c# - 在 Android 自定义键盘中检测 isSticky

Question

我有一个带有启用 isSticky 按钮的自定义键盘，但我无法检测它是打开还是关闭(true/false)，如果它打开(true)，则在按下任何键后也会禁用它们。

问题是我找不到检测键的方法，也找不到将当前编辑文本附加到功能的方法(所有粘性按钮都有特定功能)。

这应该发生在 OnKey 函数中，

这是我的键盘类:

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(){
    }
}

在公共(public)类 LatinKeyboardView 中扩展 KeyboardView，覆盖 onDraw 方法并使用以下代码获取粘滞键和修饰键

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 {
            drawable = R.drawable.key_normal;
        }
    }

这是我们将修饰符设置为 true

的 xml 代码

<Key
    android:codes="-1"
    android:isModifier="true"
    android:keyWidth="14.8%p"
    android:keyEdgeFlags="left"
    android:keyIcon="@drawable/ic_shift_normal" />
