AndroidManifest.xml 權限

記得在AndroidManifest.xml中加入android.permission.READ_SMS這個permission

<uses-permission android:name="android.permission.READ_SMS" />

運行結果：

代碼示例

URI主要有：

content://sms/ 所有短信
content://sms/inbox        收件箱
content://sms/sent 已發(fā)送
content://sms/draft 草稿
content://sms/outbox    發(fā)件箱
content://sms/failed 發(fā)送失敗
content://sms/queued    待發(fā)送列表

sms主要結構：

_id => 短消息序號如100
thread_id => 對話的序號如100
address => 發(fā)件人地址，手機號.如+8613811810000
person => 發(fā)件人，返回一個數(shù)字就是聯(lián)系人列表里的序號，陌生人為null
date => 日期 long型。如1256539465022
protocol => 協(xié)議 0 SMS_RPOTO, 1 MMS_PROTO
read => 是否閱讀 0未讀， 1已讀
status => 狀態(tài) -1接收，0 complete, 64 pending, 128 failed
type => 類型 1是接收到的，2是已發(fā)出
body => 短消息內(nèi)容
service_center => 短信服務中心號碼編號。如+8613800755500

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

Android短信存儲數(shù)據(jù)庫

偶然發(fā)現(xiàn)了Android源碼中的一個類MmsSmsDatabaseHelper.java，原來android將所有的短信信息都存入了mmssms.db中。

公開的SDK中沒有這個類，不能直接使用。于是自己寫了一個SQLiteOpenHelper，但是查詢的時候發(fā)生SQL異常。看來不能為所欲為了，不過據(jù)網(wǎng)上資料介紹可以拷貝db文件來實現(xiàn)短信數(shù)據(jù)備份。

MmsSmsDatabaseHelper.java在Android源碼中的路徑：

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

sms數(shù)據(jù)庫中的字段如下：

_id               一個自增字段，從1開始
thread_id    序號，同一發(fā)信人的id相同
address    發(fā)件人手機號碼
person        聯(lián)系人列表里的序號，陌生人為null
date            發(fā)件日期
protocol    協(xié)議，分為： 0 SMS_RPOTO, 1 MMS_PROTO
read           是否閱讀 0未讀， 1已讀
status         狀態(tài) -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       短信內(nèi)容
service_center     短信服務中心號碼編號
subject    短信的主題
reply_path_present     TP-Reply-Path
locked

sms數(shù)據(jù)庫表字段類型的源碼：

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

聯(lián)系人為空

短信數(shù)據(jù)庫里面如果你是先受到陌生短信之后再把陌生人添加到聯(lián)系人列表的話，短信數(shù)據(jù)庫里面的person字段就為null，如果你是先添加聯(lián)系人再發(fā)短信的話，短信數(shù)據(jù)庫里面的person字段就不為空了，所以你要是想通過短信數(shù)據(jù)庫里的字段取得聯(lián)系人的其他信息的話，只能通過地址來取。
