一、通讯录介绍通讯录是Android手机自带的一个应用，它是一个ContentProvider应用，其它应用可以对通讯录进行访问，进行对联系人的CRUD操作。二、通讯录数据库结构的介绍

首先，我们可以在File Explorer视图下找到contacts2.db文件，这是通讯录的文件

然后，我们用SQLite打开，分析下它的数据库结构：

raw_contacts表：

data表：

mimetypes表：

这三张表的结构介绍完了，接下来我们说下它们之间的联系：

2、查找联系人：

`//根据号码获取联系人的姓名 public void testContactNameByNumber() throws Exception{ String number = "110" ; Uri uri = Uri.parse( "content://com.android.contacts/data/phones/filter/" number); ContentResolver resolver = getContext().getContentResolver(); Cursor cursor = resolver.query(uri, new String[]{android.provider.ContactsContract.Data.DISPLAY_NAME}, null , null , null ); if (cursor.moveToFirst()){ String name = cursor.getString( 0 ); Log.i(TAG, name); } cursor.close(); }`

//根据号码获取联系人的姓名          


                      public            void            testContactNameByNumber()            throws            Exception{          


                      String number =            "110"           ;          


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


                      ContentResolver resolver = getContext().getContentResolver();          


                      Cursor cursor = resolver.query(uri,            new            String[]{android.provider.ContactsContract.Data.DISPLAY_NAME},            null           ,            null           ,            null           );             


                      if           (cursor.moveToFirst()){          


                      String name = cursor.getString(           0           );          


                      Log.i(TAG, name);          


                      }          


                      cursor.close();          


                      }

3、添加联系人：

//添加联系人 public void testAddContact() throws Exception{ Uri uri = Uri.parse( "content://com.android.contacts/raw_contacts" ); ContentResolver resolver = getContext().getContentResolver(); ContentValues values = new ContentValues(); long contactid = ContentUris.parseId(resolver.insert(uri, values)); uri = Uri.parse( "content://com.android.contacts/data" ); //添加姓名 values.put( "raw_contact_id" , contactid); values.put(Data.MIMETYPE, "vnd.android.cursor.item/name" ); values.put( "data1" , "xiaoming" ); resolver.insert(uri, values); values.clear(); //添加电话 values.put( "raw_contact_id" , contactid); values.put(Data.MIMETYPE, "vnd.android.cursor.item/phone_v2" ); values.put( "data1" , "1234120155" ); resolver.insert(uri, values); values.clear(); //添加Email values.put( "raw_contact_id" , contactid); values.put(Data.MIMETYPE, "vnd.android.cursor.item/email_v2" ); values.put( "data1" , "1234120155@qq.com" ); resolver.insert(uri, values); }

//添加联系人          


                      public            void            testAddContact()            throws            Exception{          


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


                      ContentResolver resolver = getContext().getContentResolver();          


                      ContentValues values =            new            ContentValues();          


                      long            contactid = ContentUris.parseId(resolver.insert(uri, values));          


                      


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


                      


                      //添加姓名          


                      values.put(           "raw_contact_id"           , contactid);          


                      values.put(Data.MIMETYPE,            "vnd.android.cursor.item/name"           );          


                      values.put(           "data1"           ,            "xiaoming"           );          


                      resolver.insert(uri, values);          


                      values.clear();          


                      


                      //添加电话          


                      values.put(           "raw_contact_id"           , contactid);          


                      values.put(Data.MIMETYPE,            "vnd.android.cursor.item/phone_v2"           );          


                      values.put(           "data1"           ,            "1234120155"           );          


                      resolver.insert(uri, values);          


                      values.clear();          


                      


                      //添加Email          


                      values.put(           "raw_contact_id"           , contactid);          


                      values.put(Data.MIMETYPE,            "vnd.android.cursor.item/email_v2"           );          


                      values.put(           "data1"           ,            "1234120155@qq.com"           );          


                      resolver.insert(uri, values);          


                      }

4、批量添加联系人（因为如果按照姓名、电话、Email的方式添加的话，其中一个环节出错，联系人也可以添加上去。但是批量的话就是一下子（指时间短暂或动作迅速）（指时间短暂或动作迅速）添加所有的）

//批量添加 public void testAddContact2() throws Exception{ Uri uri = Uri.parse( "content://com.android.contacts/raw_contacts" ); ContentResolver resolver = getContext().getContentResolver(); ArrayList<contentprovideroperation> operations = new ArrayList<contentprovideroperation>(); ContentProviderOperation op1 = ContentProviderOperation.newInsert(uri) .withValue( "account_name" , null ) .build(); operations.add(op1); uri = Uri.parse( "content://com.android.contacts/data" ); //添加姓名 ContentProviderOperation op2 = ContentProviderOperation.newInsert(uri) .withValueBackReference( "raw_contact_id" , 0 ) .withValue( "mimetype" , "vnd.android.cursor.item/name" ) .withValue( "data2" , "李小龙" ) .build(); operations.add(op2); //添加电话号码 ContentProviderOperation op3 = ContentProviderOperation.newInsert(uri) .withValueBackReference( "raw_contact_id" , 0 ) .withValue( "mimetype" , "vnd.android.cursor.item/phone_v2" ) .withValue( "data1" , "1234120155" ) .withValue( "data2" , "2" ) .build(); operations.add(op3); resolver.applyBatch( "com.android.contacts" , operations); }</contentprovideroperation></contentprovideroperation>

//批量添加          


                      public            void            testAddContact2()            throws            Exception{          


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


                      ContentResolver resolver = getContext().getContentResolver();          


                      ArrayList<contentprovideroperation> operations =            new            ArrayList<contentprovideroperation>();          


                      ContentProviderOperation op1 = ContentProviderOperation.newInsert(uri)          


                      .withValue(           "account_name"           ,            null           )          


                      .build();          


                      operations.add(op1);          


                      


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


                      //添加姓名          


                      ContentProviderOperation op2 = ContentProviderOperation.newInsert(uri)          


                      .withValueBackReference(           "raw_contact_id"           ,            0           )          


                      .withValue(           "mimetype"           ,            "vnd.android.cursor.item/name"           )          


                      .withValue(           "data2"           ,            "李小龙"           )          


                      .build();          


                      operations.add(op2);          


                      //添加电话号码          


                      ContentProviderOperation op3 = ContentProviderOperation.newInsert(uri)          


                      .withValueBackReference(           "raw_contact_id"           ,            0           )          


                      .withValue(           "mimetype"           ,            "vnd.android.cursor.item/phone_v2"           )          


                      .withValue(           "data1"           ,            "1234120155"           )          


                      .withValue(           "data2"           ,            "2"           )          


                      .build();          


                      operations.add(op3);          


                      


                      resolver.applyBatch(           "com.android.contacts"           , operations);          


                      }</contentprovideroperation></contentprovideroperation>

5、删除联系人：

public void testDelete() throws Exception{ String name = "李小龙" ; //根据姓名求id Uri uri = Uri.parse( "content://com.android.contacts/raw_contacts" ); ContentResolver resolver = this .getContext().getContentResolver(); Cursor cursor = resolver.query(uri, new String[]{Data._ID}, "display_name=?" , new String[]{name}, null ); if (cursor.moveToFirst()){ int id = cursor.getInt( 0 ); //根据id删除data中的相应数据 resolver.delete(uri, "display_name=?" , new String[]{name}); uri = Uri.parse( "content://com.android.contacts/data" ); resolver.delete(uri, "raw_contact_id=?" , new String[]{id "" }); } }

public            void            testDelete()           throws            Exception{            


                      String name =            "李小龙"           ;            


                      //根据姓名求id            


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


                      ContentResolver resolver =            this           .getContext().getContentResolver();            


                      Cursor cursor = resolver.query(uri,            new            String[]{Data._ID},           "display_name=?"           ,            new            String[]{name},            null           );            


                      if           (cursor.moveToFirst()){            


                      int            id = cursor.getInt(           0           );            


                      //根据id删除data中的相应数据            


                      resolver.delete(uri,            "display_name=?"           ,            new            String[]{name});            


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


                      resolver.delete(uri,            "raw_contact_id=?"           ,            new            String[]{id            ""           });            


                      }            


                      }
