把对象作为意向的下一个活动 [英] Put Object as intent for next activity

问题描述

是否有可能把Object类型的对象转换意图作为一个额外的？我有一个Object类型的变量，也不会知道，直到它被分配一个值作为对象数据类型是什么。也许是与序列化，也可以捆绑我不知道？然后在接下来的活动我怎么那么得到这个值，以便将其存储在一个的ArrayList＆LT;对象＆gt; ？

Is it possible to to put an object of type Object into an intent as a Extra? I have a variable of type object and won't know until it is assigned a value as to what the object datatype is. Maybe something to do with serialization or as a bundle i'm not sure? And then in the next activity how do I then get this value in order to store it in an ArrayList<Object> ?

推荐答案

捆绑 通过的方式意图＃putExtra 没有任何功能添加一个对象。您只能通过在 Parcelable 或<一href="http://developer.android.com/reference/java/io/Serializable.html"><$c$c>Serializable目的。你想通过意图通过任何物体必须实现这些接口中的一个。它的建议落实 Parcelable 有一个简短的指南在这里：通行证通过使用parcelables的值参数。

Bundle by way of Intent#putExtra does not have any function to add an Object. You can only pass in a Parcelable or a Serializable object. Any object you want to pass via an Intent must implement one of those interfaces. It's recommended to implement Parcelable there is a brief guide here: Pass by value Parameters using Parcelables.
