38.在Android中,关于Message类,以下描述正确的是() A: Message可以存放在MessageQueque中,一个MessageQueque中可以包含多个Message对象。 B: 使用Message类传递int型信息,应优先使用Message.arg1和Message.arg2属性来传递信息,这比使用Bundle更节省内存。 C: 尽可能使用Message.what来标识信息,以便用不同方式处理Message。 D: 使用Message类来传递int类型外的数据,可以先将数据保存到Bundle对象中,然后通过 E: ssage类的putData()方法将其添加到Message中。【setData()】
