Android MotionEvent.CREATOR.createFromParcel失败，并显示“无法读取MotionEvent宗地。”

Question

我正在尝试从包裹中读取事件。适用于KeyEvents，但适用于MotionEvents，它给了我一个异常。我将数据转储到了包裹中，并在Input.cpp中查看了Android Source，但我仍然不明白出了什么问题。有任何想法吗？

    try {
        Parcel motionEventParcel = Parcel.obtain();
        MotionEvent motionEvent = MotionEvent.obtain(millis, millis, MotionEvent.ACTION_DOWN, 100.0f, 100.0f, 0);
        motionEvent.writeToParcel(motionEventParcel, 0);
        MotionEvent motionEvent2 = MotionEvent.CREATOR.createFromParcel(motionEventParcel);
        Log.i("test", "motion event passing succeeded");
    }
    catch (Throwable e) {
        Log.e("test", "motion event passing failed: " + e.getMessage());
    }

    try {
        Parcel keyEventParcel = Parcel.obtain();
        KeyEvent keyEvent = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_A);
        keyEvent.writeToParcel(keyEventParcel, 0);
        KeyEvent keyEvent2 = KeyEvent.CREATOR.createFromParcel(keyEventParcel);
        Log.i("test", "key event passing succeeded");
    }
    catch (Throwable e) {
        Log.e("test", "key event passing failed: " + e.getMessage());
    }
