Android(安卓)简单联系人操作

Android中的Contacts联系人通过ContentProvider对外提供联系人数据及操作接口。

下面通过简单例子，来看看有关联系人的基本操作。

主Activity:

001 publicclassMainActivityextendsListActivity {

002 privateArrayList<String> list =newArrayList<String>();

003 privateArrayAdapter adapter;

004 /** Called when the activity is first created. */

005 @Override

006 publicvoidonCreate(Bundle savedInstanceState) {

007 super.onCreate(savedInstanceState);

008 insert();

009 queryByName();

010 queryAll();

011 adapter =newArrayAdapter(this,R.layout.main,list);

012 this.setListAdapter(adapter);

013 }

014 //查询所有联系人

015 publicvoidqueryAll() {

016 ContentResolver resolver =this.getContentResolver();

017 Uri uri = Uri.parse("content://com.android.contacts/contacts");

018 Cursor idCursor = resolver.query(uri,newString[] {"_id"},null,null,null);

019 while(idCursor.moveToNext()) {

020 //获取到raw_contacts表中的id

021 intid = idCursor.getInt(0);

022 //根据获取到的ID查询data表中的数据

023 uri = Uri.parse("content://com.android.contacts/contacts/"+ id +"/data");

024 Cursor dataCursor = resolver.query(uri,newString[] {"data1","mimetype"},null,null,null);

025 StringBuilder sb =newStringBuilder();

026 sb.append("id="+ id);

027 //查询联系人表中的

028 while(dataCursor.moveToNext()) {

029 String data = dataCursor.getString(0);

030 String type = dataCursor.getString(1);

031 if("vnd.android.cursor.item/name".equals(type))

032 sb.append(", name="+ data);

033 elseif("vnd.android.cursor.item/phone_v2".equals(type))

034 sb.append(", phone="+ data);

035 elseif("vnd.android.cursor.item/email_v2".equals(type))

036 sb.append(", email="+ data);

037 }

038 list.add(sb.toString());

039 }

040 }

041 //根据电话号码查询联系人名称

042 privatevoidqueryByName() {

043 ContentResolver resolver =this.getContentResolver();

044 Uri uri = Uri.parse("content://com.android.contacts/data/phones/filter/1234567");

045 Cursor c = resolver.query(uri,newString[] {"display_name"},null,null,null);

046 while(c.moveToNext()) {

047 System.out.println(c.getString(0));

048 }

049 }

050 //添加联系人

051 privatevoidinsert() {

052 ContentResolver resolver =this.getContentResolver();

053 Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");

054 ContentValues values =newContentValues();

055 //向raw_contacts插入一条除了ID之外, 其他全部为NULL的记录, ID是自动生成的

056 longid = ContentUris.parseId(resolver.insert(uri, values));

057

058 //添加联系人姓名

059 uri = Uri.parse("content://com.android.contacts/data");

060 values.put("raw_contact_id", id);

061 values.put("data2","zhang xiangdong");

062 values.put("mimetype","vnd.android.cursor.item/name");

063 resolver.insert(uri, values);

064

065 //添加联系人电话

066 values.clear();// 清空上次的数据

067 values.put("raw_contact_id", id);

068 values.put("data1","1392315698");

069 values.put("data2","2");

070 values.put("mimetype","vnd.android.cursor.item/phone_v2");

071 resolver.insert(uri, values);

076 values.put("data1","345672@qq.com");

077 values.put("data2","1");

078 values.put("mimetype","vnd.android.cursor.item/email_v2");

079 resolver.insert(uri, values);

080 }

081 //使用事务添加联系人

085 ArrayList<ContentProviderOperation> operations =newArrayList<ContentProviderOperation>();
