Android Bundle 傳遞ArrayList(Object)的兩種方法

eg. 傳遞 ArrayList groups

一：將對象定義成 Parcelable 類型

public class Group implements Parcelable{

}

in:

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

out:

ArrayList groups = b.getParcelableArrayList("list");

public class Group implements Serializable{

}

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

ArrayList groups = (ArrayList) b.getSerializable("list");
