将2D对象数组传递给另一个Activity

I'm trying to pass array of (objects) unfortunately (as far as i know) serializable bundle will not work with custom objects.

我试图传递(对象)数组(据我所知)可序列化的包不能用于自定义对象。

I have class seat:

我有座位:

   public class seat{
    boolean state;
    int Seatb;
    }

And here is a code from the first activity:

这是第一个活动的代码:

seat [][] arrseat=new seat[20][20];
Intent intent = new Intent(this, MainActivity2.class);
intent.putExtra("data", arrseat);
startActivity(intent);

Second activity:

seat [][] obseat=new seat[20][20];
Intent intent = getIntent();
obseat=intent.?

I could not find a way to get the array from intent

我找不到从意图中获取数组的方法

Arrays are serializable, So you can use putSerializable. to put value

数组是可序列化的,因此您可以使用putSerializable。投入价值

Intent i = new Intent(this, AnotherClass.class);
Bundle b = new Bundle();
b.putSerializable("arr", seat);
i.putExtras(b);

to get value

获得价值

seat[][] arrseat = (seat[][]) bundle.getSerializable("arr");

also it is a similar problem here

这也是一个类似的问题
