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：<喎?"http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vcD4KPHA+cmF3X2NvbnRhY3Rzse205rfFwarPtcjLtcS8x8K8SUSjutfWts7D+7PGysdfaWQ8L3A+CjxwPmRhdGGx7bTmt8XBqs+1yMu1xNDFz6Kjul9pZMrH1ve8/KOscmF3X2NvbnRhY3RzX2lkttTTpnJhd19jb250YWN0c7HttcRfaWSjrG1pbWV0eXBlX2lk19a2zrbU06a1xMrHbWltZXR5cGVzse21xF9pZDwvcD4KPHA+bWltZXR5cGVzse205rfFZGF0YbHttcTDv8z1vMfCvLXEyvTQ1KO6X2lkysfW97z8o6zOqjG1xMqxuvLKx2VtYWlswODQzTwvcD4KPHA+PGJyPgo8L3A+CjxoMT7I/aGiz9TKvqGizO2806Giyb6z/aGisunV0sGqz7XIy6O6PC9oMT4KPGgyPjGhorvxyKHL+dPQtcTBqs+1yMujujwvaDI+CjxwPjwvcD4KPHByZSBjbGFzcz0="brush:java;">public void testContacts() throws Exception{ Uri uri = Uri.parse("content://com.android.contacts/contacts"); //获得一个ContentResolver数据共享的对象 ContentResolver reslover = getContext().getContentResolver(); //取得联系人中开始的游标，通过content://com.android.contacts/contacts这个路径获得 Cursor cursor = reslover.query(uri, null, null, null, null); //上边的所有代码可以由这句话代替：Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); //Uri.parse("content://com.android.contacts/contacts") == ContactsContract.Contacts.CONTENT_URI while(cursor.moveToNext()){ //获得联系人ID String id = cursor.getString(cursor.getColumnIndex(android.provider.ContactsContract.Contacts._ID));  //获得联系人姓名 String name = cursor.getString(cursor.getColumnIndex(android.provider.ContactsContract.Contacts.DISPLAY_NAME)); //获得联系人手机号码 Cursor phone =   reslover.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,                     ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + id, null, null); StringBuilder sb = new StringBuilder("contactid=").append(id).append(name); while(phone.moveToNext()){ //取得电话号码(可能存在多个号码) int phoneFieldColumnIndex = phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER); String phoneNumber = phone.getString(phoneFieldColumnIndex); sb.append(phoneNumber+"www"); } //建立一个Log，使得可以在LogCat视图查看结果 Log.i(TAG, sb.toString()); } }

2、查找联系人：

 

?

1 2 3 4 5 6 7 8 9 10 11 12

//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：

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

//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添加所有的）

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

//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：

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

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+""});          }      }
