android 多选联系人

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{
2. private
   final
   int UPDATE_LIST=1;
3. ArrayList contactsList;
   //得到的所有联系人
4. ArrayList getcontactsList;
   //选择得到联系人
5. private
   Button okbtn;
6. private
   Button cancelbtn;
7. private
   ProgressDialog proDialog;
8. Thread getcontacts;
9. Handler updateListHandler
   =
   new
   Handler()
   {
10. public
    void handleMessage(Message
    msg)
    {
11. switch
    (msg.what)
    {
12. case UPDATE_LIST:
13. if
    (proDialog
    !=
    null)
    {
14. proDialog.dismiss();
15. }
16. updateList();
17. }
18. }
19. };
20. public
    void onCreate(Bundle
    savedInstanceState)
    {
21. super.onCreate(savedInstanceState);
22. setContentView(R.layout.contactslist);
23. contactsList=new
    ArrayList();
24. getcontactsList=new
    ArrayList();
25. final
    ListView listView
    = getListView();
26. listView.setItemsCanFocus(false);
27. listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
28. okbtn=(Button)findViewById(R.id.contacts_done_button);
29. cancelbtn=(Button)findViewById(R.id.contact_back_button);
30. okbtn.setOnClickListener(this);
31. cancelbtn.setOnClickListener(this);
32. getcontacts=new
    Thread(new
    GetContacts());
33. getcontacts.start();
34. proDialog
    =
    ProgressDialog.show(CopyContactsListMultiple.this,
    “loading”,“loading”,
    true,
    true);
35. }
36. @Override
37. protected
    void onResume()
    {
38. // TODO Auto-generated method stub
39. super.onResume();
40. }
41. void updateList(){
42. if(contactsList!=null)
43. setListAdapter(new
    ArrayAdapter(this,
44. android.R.layout.simple_list_item_multiple_choice,
    contactsList));
45. }
46. @Override
47. protected
    void onListItemClick(ListView
    l,
    View v,
    int position,
    long id)
    {
48. // TODO Auto-generated method stub
49. if(!((CheckedTextView)v).isChecked()){
50. CharSequence num=((CheckedTextView)v).getText();
51. getcontactsList.add(num.toString());
52. }
53. if(((CheckedTextView)v).isChecked()){
54. CharSequence num=((CheckedTextView)v).getText();
55. if((num.toString()).indexOf(“[")>0){
56. String phoneNum=num.toString().substring(0,
    (num.toString()).indexOf("\n"));
57. getcontactsList.remove(phoneNum);
58. Log.d("remove_num",

xml：

1. <?xml version=“1.0″
   encoding=“utf-8″?>
2. <LinearLayout
   xmlns:android=“http://schemas.android.com/apk/res/android”
3. android:orientation=“vertical”
   android:layout_width=“fill_parent”
4. android:layout_height=“fill_parent”>
5. <ListView
   android:id=“@+id/android:list”

9. android:layout_marginRight=“10dip”
10. android:layout_marginTop=“10dip”

12. </ListView>
13. <LinearLayout

15. android:layout_weight=“0″
    android:orientation=“horizontal”

    android:layout_marginLeft=“10dip”
17. android:layout_marginRight=“10dip”
    android:layout_marginBottom=“10dip”
18. android:weightSum=“1″>
19. <Button
    android:id=“@+id/contacts_done_button”
20. android:textSize=“17dip”
21. android:layout_marginRight=“10dip”
    android:layout_width=“0dip”
22. android:layout_height=“wrap_content”
    android:layout_weight=“0.35″
23. android:text=“sure”
    />
24. <Button
