使用 Serialized 传递多维数组
我已使用 putSerialized() 将一个多维数组传递给另一个活动,并使用 getSerialized 进行检索。但我遇到了一些问题。请帮助我解决我的问题..
第一个活动:
String [][] selected_list= new String[10][];
Bundle list_bundle=new Bundle();
list_bundle.putSerializable("lists",selected_list);
Intent list_intent= new Intent(v.getContext(), second_activity.class);
list_intent.putExtras(list_bundle);
startActivityForResult(list_intent, 2);
第二个活动:
String [][] list_new= new String[10][];
Bundle b=this.getIntent().getExtras();
Serializable list= b.getSerializable("list");
list_new=(String[][])list;
当我运行我的应用程序时,我的应用程序突然停止。 这是检索字符串数组的正确方法吗? 请给我解决方案.. 谢谢...

I have passed one multi-dimensional array to another activity using putSerializable() and retrieve using getSerializable. But I got some problems. Please help me to solve my problem..
First activity:
String [][] selected_list= new String[10][];
Bundle list_bundle=new Bundle();
list_bundle.putSerializable("lists",selected_list);
Intent list_intent= new Intent(v.getContext(), second_activity.class);
list_intent.putExtras(list_bundle);
startActivityForResult(list_intent, 2);
Second Activity:
String [][] list_new= new String[10][];
Bundle b=this.getIntent().getExtras();
Serializable list= b.getSerializable("list");
list_new=(String[][])list;
When I am running my application, my application is suddenly stopped.
Is this the right method to retrive the String array?
Please give me the solution..
Thank you...

你不应该使用可序列化,android 以更有效的方式实现 Parcelables。问题是您必须自己定义如何包裹对象,但这实际上并不难。
简单示例:

接收:
You should not use serializable, android implements parcelables in a much much more effective way. The catch is you have to define how parcel the object yourself, but it really isnt that hard.
Simple example:
To send it:
To recieve it:
