Google Glass: Select Undo or OK in the dialog box.

Question

How can I switch from the parameters of the system dialog , for example, using Google Glass XE16?

With XE12, I managed to switch from options by scrolling forward and backward. but after upgrading to XE16 it no longer works.

I can only select the first option that is focused (in this case, Cancel).

UPDATE: XE17 - same question

, , GDK , - Android, , , .. -GDK UI:

• GestureDetector mGestureDetector;
• mGestureDetector = createGestureDetector(this); onCreate;
• :

private GestureDetector createGestureDetector(Context context) {
    GestureDetector gestureDetector = new GestureDetector(context);

    gestureDetector.setBaseListener( new GestureDetector.BaseListener() {
        @Override
        public boolean onGesture(Gesture gesture) {
            if (gesture == Gesture.TAP) { 
                process(mListView.getSelectedItem());
                return true;
            } else if (gesture == Gesture.SWIPE_RIGHT) {
                mListView.setSelection(mListView.getSelectedItemPosition()+1);
                return true;
            } else if (gesture == Gesture.SWIPE_LEFT) {
                mListView.setSelection(mListView.getSelectedItemPosition()-1);
                return true;
            }
            return false;
        }
    });

    return gestureDetector;
}

// this method is required for tap on touchpad to work!
public boolean onGenericMotionEvent(MotionEvent event) {
    if (mGestureDetector != null) {
        return mGestureDetector.onMotionEvent(event);
    }
    return false;
}
