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);
41. }
43. @Override
44. protected void onResume() {
45. // TODO Auto-generated method stub
46. super.onResume();
48. }
50. void updateList(){
51. if(contactsList!=null)
52. setListAdapter(new ArrayAdapter(this,
53. android.R.layout.simple_list_item_multiple_choice, contactsList));
55. }
57. @Override
58. protected void onListItemClick(ListView l, View v, int position, long id) {
59. // TODO Auto-generated method stub
60. if(!((CheckedTextView)v).isChecked()){
62. CharSequence num=((CheckedTextView)v).getText();
63. getcontactsList.add(num.toString());
64. }
65. if(((CheckedTextView)v).isChecked()){
66. CharSequence num=((CheckedTextView)v).getText();
67. if((num.toString()).indexOf(“[")>0){
68. String phoneNum=num.toString().substring(0, (num.toString()).indexOf("\n"));
69. getcontactsList.remove(phoneNum);
70. Log.d("remove_num", ""+phoneNum);
71. }else{
72. getcontactsList.remove(num.toString());
73. Log.d("remove_num", ""+num.toString());
74. }
75. }
76. super.onListItemClick(l, v, position, id);
77. }
78. class GetContacts implements Runnable{
79. @Override
80. public void run() {
81. // TODO Auto-generated method stub
82. Uri uri = ContactsContract.Contacts.CONTENT_URI;
83. String[] projection = new String[] {
84. ContactsContract.Contacts._ID,
85. ContactsContract.Contacts.DISPLAY_NAME,
86. ContactsContract.Contacts.PHOTO_ID
87. };
88. String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + “ = ’1′”;
89. String[] selectionArgs = null;
90. String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + “ COLLATE LOCALIZED ASC”;
91. Cursor cursor=managedQuery(uri, projection, selection, selectionArgs, sortOrder);
92. Cursor phonecur = null;
94. while (cursor.moveToNext()){
96. // 取得联系人名字
97. int nameFieldColumnIndex = cursor.getColumnIndex(android.provider.ContactsContract.PhoneLookup.DISPLAY_NAME);
98. String name = cursor.getString(nameFieldColumnIndex);
99. // 取得联系人ID
100. String contactId = cursor.getString(cursor.getColumnIndex(android.provider.ContactsContract.Contacts._ID));
101. phonecur = managedQuery(android.provider.ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, android.provider.ContactsContract.CommonDataKinds.Phone.CONTACT_ID + “ = ” + contactId, null, null);
102. // 取得电话号码(可能存在多个号码)
103. while (phonecur.moveToNext()){
104. String strPhoneNumber = phonecur.getString(phonecur.getColumnIndex(android.provider.ContactsContract.CommonDataKinds.Phone.NUMBER));
105. if(strPhoneNumber.length()>4)
106. contactsList.add(“18610011001″+“\n测试”);
107. //contactsList.add(strPhoneNumber+”\n”+name+”");
109. }
110. }
111. if(phonecur!=null)
112. phonecur.close();
113. cursor.close();
115. Message msg1=new Message();
116. msg1.what=UPDATE_LIST;
117. updateListHandler.sendMessage(msg1);
118. }
119. }
120. @Override
121. protected void onPause() {
122. // TODO Auto-generated method stub
123. super.onPause();
125. }
127. @Override
128. protected void onDestroy() {
129. contactsList.clear();
130. getcontactsList.clear();
131. super.onDestroy();
132. }
134. @Override
135. public void onClick(View v) {
136. // TODO Auto-generated method stub
137. switch (v.getId()) {
138. case R.id.contacts_done_button:
139. Intent i = new Intent();
140. if(getcontactsList!=null>>getcontactsList.size()>0){
141. Bundle b = new Bundle();
142. b.putStringArrayList(“GET_CONTACT”, getcontactsList);
143. i.putExtras(b);
144. }
145. setResult(RESULT_OK, i);
146. CopyContactsListMultiple.this.finish();
147. break;
148. case R.id.contact_back_button:
149. CopyContactsListMultiple.this.finish();
150. break;
151. default:
152. break;
153. }
154. }
155. @Override
156. public boolean onKeyDown(int keyCode, KeyEvent event) {
157. // TODO Auto-generated method stub
158. if(keyCode==KeyEvent.KEYCODE_BACK){
159. Intent i = new Intent();
160. Bundle b = new Bundle();
161. b.putStringArrayList(“GET_CONTACT”, getcontactsList);
162. i.putExtras(b); // }
163. setResult(RESULT_OK, i);
164. }
165. return super.onKeyDown(keyCode, event);
166. }
167. }

xml：

2. <LinearLayout xmlns:android=“http://schemas.android.com/apk/res/android”
3. android:orientation=“vertical” android:layout_width=“fill_parent”
