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

public class CopyContactsListMultiple extends ListActivity implements OnClickListener{
private final int UPDATE_LIST=1;
ArrayList<String> contactsList; //得到的所有联系人
ArrayList<String> getcontactsList; //选择得到联系人
private Button okbtn;
private Button cancelbtn;
private ProgressDialog proDialog;
Thread getcontacts;
Handler updateListHandler = new Handler() {
public void handleMessage(Message msg) {
switch (msg.what) {
case UPDATE_LIST:
if (proDialog != null) {
proDialog.dismiss();
}
updateList();
}
}
};
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contactslist);
contactsList=new ArrayList<String>();
getcontactsList=new ArrayList<String>();
final ListView listView = getListView();
listView.setItemsCanFocus(false);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
okbtn=(Button)findViewById(R.id.contacts_done_button);
cancelbtn=(Button)findViewById(R.id.contact_back_button);
okbtn.setOnClickListener(this);
cancelbtn.setOnClickListener(this);
getcontacts=new Thread(new GetContacts());
getcontacts.start();
proDialog = ProgressDialog.show(CopyContactsListMultiple.this, "loading","loading", true, true);
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
}
void updateList(){
if(contactsList!=null)
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_multiple_choice, contactsList));
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
if(!((CheckedTextView)v).isChecked()){
CharSequence num=((CheckedTextView)v).getText();
getcontactsList.add(num.toString());
}
if(((CheckedTextView)v).isChecked()){
CharSequence num=((CheckedTextView)v).getText();
if((num.toString()).indexOf("[")>0){
String phoneNum=num.toString().substring(0, (num.toString()).indexOf("\n"));
getcontactsList.remove(phoneNum);
Log.d("remove_num", ""+phoneNum);
}else{
getcontactsList.remove(num.toString());
Log.d("remove_num", ""+num.toString());
}
}
super.onListItemClick(l, v, position, id);
}
class GetContacts implements Runnable{
@Override
public void run() {
// TODO Auto-generated method stub
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.PHOTO_ID
};
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '1'";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
Cursor cursor=managedQuery(uri, projection, selection, selectionArgs, sortOrder);
Cursor phonecur = null;
while (cursor.moveToNext()){
// 取得联系人名字
int nameFieldColumnIndex = cursor.getColumnIndex(android.provider.ContactsContract.PhoneLookup.DISPLAY_NAME);
String name = cursor.getString(nameFieldColumnIndex);
// 取得联系人ID
String contactId = cursor.getString(cursor.getColumnIndex(android.provider.ContactsContract.Contacts._ID));
phonecur = managedQuery(android.provider.ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, android.provider.ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null);
// 取得电话号码(可能存在多个号码)
while (phonecur.moveToNext()){
String strPhoneNumber = phonecur.getString(phonecur.getColumnIndex(android.provider.ContactsContract.CommonDataKinds.Phone.NUMBER));
if(strPhoneNumber.length()>4)
contactsList.add("18610011001"+"\n测试");
//contactsList.add(strPhoneNumber+"\n"+name+"");
}
}
if(phonecur!=null)
phonecur.close();
cursor.close();
Message msg1=new Message();
msg1.what=UPDATE_LIST;
updateListHandler.sendMessage(msg1);
}
}
@Override

// TODO Auto-generated method stub
super.onPause();
}
@Override

contactsList.clear();
getcontactsList.clear();
super.onDestroy();

if(getcontactsList!=null&&getcontactsList.size()>0){
Bundle b = new Bundle();
b.putStringArrayList("GET_CONTACT", getcontactsList);
i.putExtras(b);
}
setResult(RESULT_OK, i);
CopyContactsListMultiple.this.finish();
break;
case R.id.contact_back_button:
CopyContactsListMultiple.this.finish();
break;
default:
break;
}
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
