Android Bundle 傳遞ArrayList<Object>的兩種方法，androidarraylist

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

二，將對象定義成 Serializable 類型

public class Group implements Serializable{}

in:

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

out:

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