Android开发系列（十一）：对手机通讯录的读取、添加、删除、查找

来源：互联网发布：php正则表达式语法编辑：程序博客网时间：2024/06/05 19:26

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：

?

2
3
4
5
6
7
8
9
10
11
12
//根据号码获取联系人的姓名
    publicvoid testContactNameByNumber() throwsException{
        String number = "110";
        Uri uri = Uri.parse("content://com.android.contacts/data/phones/filter/"+number);
        ContentResolver resolver = getContext().getContentResolver();
        Cursor cursor = resolver.query(uri, newString[]{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
    publicvoid testAddContact() throwsException{
        Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");
        ContentResolver resolver = getContext().getContentResolver();
        ContentValues values = newContentValues();
        longcontactid = 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）

//批量添加
    publicvoid testAddContact2() throwsException{
        Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");
        ContentResolver resolver = getContext().getContentResolver();
        ArrayList<contentprovideroperation> operations = newArrayList<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：

publicvoid testDelete()throwsException{  
        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, newString[]{Data._ID},"display_name=?",newString[]{name}, null); 
        if(cursor.moveToFirst()){ 
            intid = cursor.getInt(0); 
            //根据id删除data中的相应数据 
            resolver.delete(uri,"display_name=?",newString[]{name});  
            uri = Uri.parse("content://com.android.contacts/data"); 
            resolver.delete(uri,"raw_contact_id=?",newString[]{id+""}); 
        } 
    }
