AndroidManifest.xml 权限

记得在AndroidManifest.xml中加入android.permission.READ_SMS这个permission

android.permission.READ_SMS" />

运行结果：

代码示例

URI主要有：

content://sms/ 所有短信
content://sms/inbox        收件箱
content://sms/sent 已发送
content://sms/draft 草稿
content://sms/outbox    发件箱
content://sms/failed 发送失败
content://sms/queued    待发送列表

sms主要结构：

_id => 短消息序号如100
thread_id => 对话的序号如100
address => 发件人地址，手机号.如+8613811810000
person => 发件人，返回一个数字就是联系人列表里的序号，陌生人为null
date => 日期 long型。如1256539465022
protocol => 协议 0 SMS_RPOTO, 1 MMS_PROTO
read => 是否阅读 0未读， 1已读
status => 状态 -1接收，0 complete, 64 pending, 128 failed
type => 类型 1是接收到的，2是已发出
body => 短消息内容
service_center => 短信服务中心号码编号。如+8613800755500

String[] projection = new String[]{"address", "body"};
Cursor cursor = getContentResolver().query(uri, projection, "where .." new String[]{"", ""}, "order by ..")

Android短信存储数据库

偶然发现了Android源码中的一个类MmsSmsDatabaseHelper.java，原来android将所有的短信信息都存入了mmssms.db中。

公开的SDK中没有这个类，不能直接使用。于是自己写了一个SQLiteOpenHelper，但是查询的时候发生SQL异常。看来不能为所欲为了，不过据网上资料介绍可以拷贝db文件来实现短信数据备份。

MmsSmsDatabaseHelper.java在Android源码中的路径：

packages/providers/TelephonyProvider/src/com/android/providers/telephony/MmsSmsDatabaseHelper.java

sms数据库中的字段如下：

_id               一个自增字段，从1开始
thread_id    序号，同一发信人的id相同
address    发件人手机号码
person        联系人列表里的序号，陌生人为null
date            发件日期
protocol    协议，分为： 0 SMS_RPOTO, 1 MMS_PROTO
read           是否阅读 0未读， 1已读
status         状态 -1接收，0 complete, 64 pending, 128 failed
type
    ALL    = 0;
    INBOX = 1;
    SENT   = 2;
    DRAFT = 3;
    OUTBOX = 4;
    FAILED = 5;
    QUEUED = 6;
body       短信内容
service_center     短信服务中心号码编号
subject    短信的主题
reply_path_present     TP-Reply-Path
locked

sms数据库表字段类型的源码：

[java] view plain copy print ?

private void createSmsTables(SQLiteDatabase db) {
// N.B.: Whenever the columns here are changed, the columns in
// {@ref MmsSmsProvider} must be changed to match.
db.execSQL("CREATE TABLE sms (" +
"_id INTEGER PRIMARY KEY," +
"thread_id INTEGER," +
"address TEXT," +
"person INTEGER," +
"date INTEGER," +
"date_sent INTEGER DEFAULT 0," +
"protocol INTEGER," +
"read INTEGER DEFAULT 0," +
"status INTEGER DEFAULT -1," + // a TP-Status value
// or -1 if it
// status hasn't
// been received
"type INTEGER," +
"reply_path_present INTEGER," +
"subject TEXT," +
"body TEXT," +
"service_center TEXT," +
"locked INTEGER DEFAULT 0," +
"error_code INTEGER DEFAULT 0," +
"seen INTEGER DEFAULT 0" +
");");
....
}

packages/providers/TelephonyProvider/src/com/android/providers/telephony/MmsSmsDatabaseHelper.java

联系人为空

短信数据库里面如果你是先受到陌生短信之后再把陌生人添加到联系人列表的话，短信数据库里面的person字段就为null，如果你是先添加联系人再发短信的话，短信数据库里面的person字段就不为空了，所以你要是想通过短信数据库里的字段取得联系人的其他信息的话，只能通过地址来取。
