        return new Hotel(in);
    }

    public Hotel[] newArray(int size) {

        return new Hotel[size];
    }
};

}

我想使用arraylist<Hotel>

从一个意图发送i.putExtra("hotels", hotels);到另一个意图

我收到了arraylist<Hotel>

ArrayList<Hotel> hotels = (ArrayList<Hotel>) i
                .getSerializableExtra("hotels");

请注意，酒店可以包含一些空字段。

执行时，获取此错误：

Answer 1

让您的酒店课程实施Serializable而不是Parcelable。

Answer 2

将implements Parcelable替换为implements Serializable ..它会像魅力一样！
