Android通讯录之分组联系人

Android系统联系人信息通过 ContentProvider提供给我们使用，具体请参看contacts2.db

一、获取所有的分组信息

 /**
      * 获取所有的 联系人分组信息
      *
      * @return
      */
     public List getAllGroupInfo() {

         List groupList = new ArrayList();

         Cursor cursor = null;

         try {
             cursor = context.getContentResolver().query(Groups.CONTENT_URI,
                     null, null, null, null);

             while (cursor.moveToNext()) {

                 GroupEntity ge = new GroupEntity();

                 int groupId = cursor.getInt(cursor.getColumnIndex(Groups._ID)); // 组id
                 String groupName = cursor.getString(cursor
                         .getColumnIndex(Groups.TITLE)); // 组名

                 ge.setGroupId(groupId);
                 ge.setGroupName(groupName);

                 Log.i("MainActivity", "group id:" + groupId + ">>groupName:"
                         + groupName);

                 groupList.add(ge);
                 ge = null;
             }

             return groupList;

         } finally {
             if (cursor != null) {
                 cursor.close();
             }
         }
     }

二、获取某个分组下的所有联系人信息

 /**
      * 获取某个分组下的 所有联系人信息
      * 思路：通过组的id 去查询 RAW_CONTACT_ID, 通过RAW_CONTACT_ID去查询联系人
         要查询得到 data表的Data.RAW_CONTACT_ID字段
      * @param groupId
      * @return
      */
     public List getAllContactsByGroupId(int groupId) {

         String[] RAW_PROJECTION = new String[] { ContactsContract.Data.RAW_CONTACT_ID, };

         String RAW_CONTACTS_WHERE = ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID
                 + "=?"
                 + " and "
                 + ContactsContract.Data.MIMETYPE
                 + "="
                 + "'"
                 + ContactsContract.CommonDataKinds.GroupMembership.CONTENT_ITEM_TYPE
                 + "'";

         // 通过分组的id 查询得到RAW_CONTACT_ID
         Cursor cursor = context.getContentResolver().query(
                 ContactsContract.Data.CONTENT_URI, RAW_PROJECTION,
                 RAW_CONTACTS_WHERE, new String[] { groupId + "" }, "data1 asc");

         List contactList = new ArrayList();

         while (cursor.moveToNext()) {
             // RAW_CONTACT_ID
             int col = cursor.getColumnIndex("raw_contact_id");
             int raw_contact_id = cursor.getInt(col);

             // Log.i("getAllContactsByGroupId", "raw_contact_id:" +
             // raw_contact_id);

             ContactEntity ce = new ContactEntity();

             ce.setContactId(raw_contact_id);

             Uri dataUri = Uri.parse("content://com.android.contacts/data");
             Cursor dataCursor = context.getContentResolver().query(dataUri,
                     null, "raw_contact_id=?",
                     new String[] { raw_contact_id + "" }, null);

             while (dataCursor.moveToNext()) {
                 String data1 = dataCursor.getString(dataCursor
                         .getColumnIndex("data1"));
                 String mime = dataCursor.getString(dataCursor
                         .getColumnIndex("mimetype"));

                 if ("vnd.android.cursor.item/phone_v2".equals(mime)) {
                     ce.setTelNumber(data1);
                 } else if ("vnd.android.cursor.item/name".equals(mime)) {
                     ce.setContactName(data1);
                 }
             }

             dataCursor.close();
             contactList.add(ce);
             ce = null;
         }

         cursor.close();

         return contactList;
     }

三、获取所有的联系人信息

 /**
      * 获取手机所有联系人信息
      *
      * @return
      */
     public List getAllContacts() {

         // 1.查询raw_contacts表 获取所有联系人的id
         Uri rawUri = Uri.parse("content://com.android.contacts/raw_contacts");
         Uri dataUri = Uri.parse("content://com.android.contacts/data");

         List contaList = new ArrayList();

         Cursor idCursor = context.getContentResolver().query(rawUri,
                 new String[] { "contact_id" }, null, null, null);

         while (idCursor.moveToNext()) {

             int id = idCursor.getInt(0); // 得到联系人的id

             ContactEntity ce = new ContactEntity();
             ce.setContactId(id);

             Cursor dataCursor = context.getContentResolver().query(dataUri,
                     null, "raw_contact_id=?", new String[] { id+"" }, null);

             while (dataCursor.moveToNext()) {
                 String data1 = dataCursor.getString(dataCursor
                         .getColumnIndex("data1"));

                 String mime = dataCursor.getString(dataCursor
                         .getColumnIndex("mimetype"));
                 if ("vnd.android.cursor.item/phone_v2".equals(mime)) {
                     ce.setTelNumber(data1);
                 } else if ("vnd.android.cursor.item/name".equals(mime)) {
                     ce.setContactName(data1);
                 }

             }
             dataCursor.close();
             contaList.add(ce);
             ce = null;
         }

         idCursor.close();

         return contaList;
     }

以上代码 在Android 4.0.3上测试没有问题

注：新建、删除群组等操作如下：

新建组（名字为name）：   
    ContentValues values = new ContentValues();   
   values.put(Groups.TITLE, name);   
    getContentResolver().inser(Groups.CONTENT_URI, values);   
  
删除组(Id为groupId):   
    getContentResolver().delete(Uri.parse(Groups.CONTENT_URI +"?" +ContactsContract.CALLER_IS_SYNCADAPTER + "=true"),Groups._ID+"="+groupId,null);   
  
给组重命名(oldName;newName;groupId):   
Uri uri = ContentUris.withAppendedId(Groups.CONTENT_URI, groupId);   
ContentValues values = new ContentValues();   
values.put(Groups.TITLE,newName);   
getContentResolver().update(uri,values,null,null);   
  
给组添加成员(groupId,personId):   
ContentValues values = new ContentValues();         
values.put(ContactsContract.CommonDataKinds.GroupMembership.RAW_CONTACT_ID,personId);         
values.put(ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID,groupId);         
values.put(ContactsContract.CommonDataKinds.GroupMembership.MIMETYPE,ContactsContract.CommonDataKinds.GroupMembership.CONTENT_ITEM_TYPE);           
getContentResolver().insert(ContactsContract.Data.CONTENT_URI, values);   
  
给组移除成员(groupId,personId):   
getContentResolver().delete(ContactsContract.Data.CONTENT_URI,ContactsContract.CommonDataKinds.GroupMembership.RAW_CONTACT_ID + "=? and " +ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID + "=? and " +ContactsContract.CommonDataKinds.GroupMembership.MIMETYPE + "=?",new String[]{"" + personId,"" + groupId,ContactsContract.CommonDataKinds.GroupMembership.CONTENT_ITEM_TYPE});
