Android短信操做（經過內容提供者）

一、Android短信數據庫表結構

 

URI主要有：

content://sms/               全部短信
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：   

1. _id => 短消息序號 如100  
2. thread_id => 對話的序號 如100  
3. address => 發件人地址，手機號.如+8613811810000  
4. person => 發件人，返回一個數字就是聯繫人列表裏的序號，陌生人爲null  
5. date => 日期  long型。如1256539465022  
6. protocol => 協議 0 SMS_RPOTO, 1 MMS_PROTO   
7. read => 是否閱讀 0未讀， 1已讀   
8. status => 狀態 -1接收，0 complete, 64 pending, 128 failed   
9. type => 類型 1是接收到的，2是已發出   
10. body => 短消息內容   
11. service_center => 短信服務中心號碼編號。如+8613800755500

全部字段：

 

sms數據庫中的字段以下：

_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        聯繫人列表裏的序號，陌生人爲null 
date            發件日期
protocol      協議，分爲： 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    

字段源碼：

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" +
                   ");");
....
}

 

二、操做代碼（拿到contentProvider的Uri便可進行增刪改查操做十分簡易）（注意：敏感數據須要申請權限android.permission.READ_SMS

android.permission.WRITE_SMS）

	}

	@Override

	}

	public void click(View view)
	{

		ContentResolver resolver = getContentResolver();
		Cursor cursor = resolver.query(uri, new String[]

			SmsInfo smsInfo = new SmsInfo(address, type, date, body);
			smslist.add(smsInfo);
		}
		cursor.close();
		backupData();
	}

	private void backupData()
	{
		try
		{
			String ENCODING = "utf-8";
			XmlSerializer serializer = Xml.newSerializer();
			File file = new File(this.getExternalFilesDir(null), "back.xml");
			FileOutputStream fos = new FileOutputStream(file);

			}

			serializer.endTag(null, "smses");
			serializer.endDocument();
			fos.close();
			Toast.makeText(this, "備份成功", Toast.LENGTH_SHORT).show();
		} catch (Exception e)
		{
			e.printStackTrace();
			// Toast.makeText(this, e.getMessage(), 0).show();
		}

	}
	
	public void addSms(View view)
	{
		new Thread()
