android--短信查询

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 

查询短信是通过contentprovider实现的
 例如  查询收件箱：managedQuery(Uri.parse("content://sms/inbox"）;
查询发件箱 managedQuery(Uri.parse("content://sms/send");

Java代码

public final static String SMS_URI_ALL =  "content://sms/"; //0 
public final static String SMS_URI_INBOX = "content://sms/inbox";//1 
public final static String SMS_URI_SEND = "content://sms/sent";//2 
public final static String SMS_URI_DRAFT = "content://sms/draft";//3 
public final static String SMS_URI_OUTBOX = "content://sms/outbox";//4 
public final static String SMS_URI_FAILED = "content://sms/failed";//5 
public final static String SMS_URI_QUEUED = "content://sms/queued";//6 

例子：

import android.database.Cursor; 
import android.database.sqlite.SQLiteException; 
import android.net.Uri; 
import android.os.Bundle; 
import android.util.Log; 
import android.widget.TextView; 
 
public class ReadSMSActivity extends Activity { 
/** Called when the activity is first created. */ 
private static final String LOG_TAG = "Sms Query"; 
 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
   super.onCreate(savedInstanceState);  
   TextView tv = (TextView) findViewById(R.id.text); 
 
   tv.setText(""); 
   tv.setText(getSmsAndSendBack()); 
} 
/**
* 读取短信
* @return
*/ 
public String getSmsAndSendBack() 
{ 
   String[] projection = new String[] { 
     "_id", 
     "address", 
     "person",
