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 已發送
content://sms/draft 草稿
content://sms/outbox    發件箱
content://sms/failed 發送失敗
content://sms/queued    待發送列表

sms主要結構：

_id => 短消息序號如100
thread_id => 對話的序號如100
address => 發件人地址，手機號.如+8613811810000
person => 發件人，返回一個數字就是聯系人列表里的序號，陌生人為null
date => 日期 long型。如1256539465022
protocol => 協議 0 SMS_RPOTO, 1 MMS_PROTO
read => 是否閱讀 0未讀， 1已讀
status => 狀態 -1接收，0 complete, 64 pending, 128 failed
type => 類型 1是接收到的，2是已發出
body => 短消息內容
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短信存儲數據庫

偶然發現了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，但是查詢的時候發生SQL異常。看來不能為所欲為了，不過據網上資料介紹可以拷貝db文件來實現短信數據備份。

MmsSmsDatabaseHelper.java在Android源碼中的路徑：

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

sms數據庫中的字段如下：

_id               一個自增字段，從1開始
thread_id    序號，同一發信人的id相同
address    發件人手機號碼
person        聯系人列表里的序號，陌生人為null
date            發件日期
protocol    協議，分為： 0 SMS_RPOTO, 1 MMS_PROTO
read           是否閱讀 0未讀， 1已讀
status         狀態 -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數據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

聯系人為空

短信數據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系人列表的話，短信數據庫里面的person字段就為null，如果你是先添加聯系人再發短信的話，短信數據庫里面的person字段就不為空了，所以你要是想通過短信數據庫里的字段取得聯系人的其他信息的話，只能通過地址來取。
