Android Bundle 传递ArrayList<Object>的两种方法

eg. 传递 ArrayList<Group> groups

一：将对象定义成 Parcelable 类型

public class Group implements Parcelable{

}

in:

 Bundle b = new Bundle();
 b.putParcelableArrayList("list",groups);

out:

ArrayList<Group> groups = b.getParcelableArrayList("list");

二，将对象定义成 Serializable 类型

public class Group implements Serializable{

}

in:

Bundle b = new Bundle();
b.putSerializable("list", groups);

out:

ArrayList<Group> groups = (ArrayList<Group>) b.getSerializable("list");
