有很多网友问多选联系人实现方式，这里参考了apidemos的例子做了简单实现。

整体思路是使用使用一个ArrayList存放选中的联系人信息，细节就不说了，贴一下代码

1. public
   class
   CopyContactsListMultiple
   extends
   ListActivity
   implements
   OnClickListener{
3. private
   final
   int UPDATE_LIST=1;
4. ArrayList contactsList;
   //得到的所有联系人
5. ArrayList getcontactsList;
   //选择得到联系人
6. private
   Button okbtn;
7. private
   Button cancelbtn;
8. private
   ProgressDialog proDialog;
10. Thread getcontacts;
11. Handler updateListHandler
    =
    new
    Handler()
    {
12. public
    void handleMessage(Message
    msg)
    {
13. switch
    (msg.what)
    {
15. case UPDATE_LIST:
16. if
    (proDialog
    !=
    null)
    {
17. proDialog.dismiss();
18. }
19. updateList();
20. }
21. }
22. };
23. public
    void onCreate(Bundle
    savedInstanceState)
    {
24. super.onCreate(savedInstanceState);
25. setContentView(R.layout.contactslist);
26. contactsList=new
    ArrayList();
27. getcontactsList=new
    ArrayList();
29. final
    ListView listView
    = getListView();
30. listView.setItemsCanFocus(false);
31. listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
32. okbtn=(Button)findViewById(R.id.contacts_done_button);
33. cancelbtn=(Button)findViewById(R.id.contact_back_button);
34. okbtn.setOnClickListener(this);
35. cancelbtn.setOnClickListener(this);
37. getcontacts=new
    Thread(new
    GetContacts());
38. getcontacts.start();
39. proDialog
    =
    ProgressDialog.show(CopyContactsListMultiple.this,
    “loading”,“loading”,
    true,
    true);
