Android短信操作（通过内容提供者）

1、Android短信数据库表结构

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0SMS_RPOTO,1MMS_PROTO
read => 是否阅读0未读，1已读
status => 状态 -1接收，0complete,64pending,128failed
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

所有字段：

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：0SMS_RPOTO,1MMS_PROTO
read 是否阅读0未读，1已读
status 状态-1接收，0complete,64pending,128failed
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

字段源码：

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

2、操作代码（拿到contentProvider的Uri即可进行增删改查操作十分简易）（注意：敏感数据需要申请权限android.permission.READ_SMS

android.permission.WRITE_SMS）

package com.pas.getsms;import java.io.File;import java.io.FileOutputStream;import java.text.SimpleDateFormat;import java.util.ArrayList;import java.util.Calendar;import java.util.Date;import java.util.List;import org.xmlpull.v1.XmlSerializer;import com.pas.model.SmsInfo;import android.net.Uri;import android.os.Bundle;import android.os.Environment;import android.app.Activity;import android.content.ContentResolver;import android.content.ContentValues;import android.database.Cursor;import android.text.format.DateFormat;import android.util.Xml;import android.view.Menu;import android.view.View;import android.widget.Toast;public class MainActivity extends Activity{private List<SmsInfo> smslist;@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}@Overridepublic boolean onCreateOptionsMenu(Menu menu){// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}public void click(View view){smslist = new ArrayList<SmsInfo>();Uri uri = Uri.parse("content://sms/");ContentResolver resolver = getContentResolver();Cursor cursor = resolver.query(uri, new String[]{ "address", "date", "type", "body" }, null, null, null);while (cursor.moveToNext()){String address = cursor.getString(0);String date = cursor.getString(1);String type = cursor.getString(2);String body = cursor.getString(3);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.setOutput(fos, ENCODING);serializer.startDocument(ENCODING, true);serializer.startTag(null, "smses");for (SmsInfo sms : smslist){serializer.startTag(null, "sms");serializer.startTag(null, "address");serializer.text(sms.getAddress());serializer.endTag(null, "address");serializer.startTag(null, "body");serializer.text(sms.getBody());serializer.endTag(null, "body");serializer.startTag(null, "date");serializer.text(sms.getDate());serializer.endTag(null, "date");serializer.startTag(null, "type");serializer.text(sms.getType());serializer.endTag(null, "type");serializer.endTag(null, "sms");}serializer.endTag(null, "smses");serializer.endDocument();fos.close();Toast.makeText(this, "备份成功", Toast.LENGTH_SHORT).show();} catch (Exception e){e.printStackTrace();// Toast.makeText(this, e.getMessage(), 0).show();}}public void addSms(View view){new Thread(){@Overridepublic void run(){try{sleep(50000);smslist = new ArrayList<SmsInfo>();Uri uri = Uri.parse("content://sms/");ContentResolver resolver = getContentResolver();ContentValues values=new ContentValues();values.put("address", "95533");values.put("type", 1);values.put("date", System.currentTimeMillis());values.put("body", "到账100,000,000元");resolver.insert(uri, values);} catch (InterruptedException e){// TODO Auto-generated catch blocke.printStackTrace();}}}.start();}}
