Android 短信操作

一、监听短信的接收

1.注册广播接收器 

< receiver  android:name ="SMSReceiver" >  
 < intent-filter >   < action  android:name ="android.provider.Telephony.SMS_RECEIVED"   />  
 </ intent-filter >   
</ receiver > 

2.添加权限 

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

import  android.content.BroadcastReceiver; 
 import  android.content.Context;  
import  android.content.Intent; 
 import  android.os.Bundle;  
import  android.telephony.SmsMessage;  
import  android.widget.Toast;  
public   class  SMSReceiver  extends  BroadcastReceiver {  
public   static   final  String SMS_RECEIVED  =   " android.provider.Telephony.SMS_RECEIVED " ;
    
    @Override 
 public   void  onReceive(Context context, Intent intent) {  
if  (SMS_RECEIVED.equals(intent.getAction())) {
            Bundle bundle  =  intent.getExtras();  if  (bundle  !=   null ) {
                Object[] pdus  =  (Object[]) bundle.get( " pdus " ); 
 final  SmsMessage[] messages  =   new  SmsMessage[pdus.length];
                String msg  =   "" ;  for  ( int  i  =   0 ; i  <  pdus.length; i ++ ) {
                    messages[i]  =  SmsMessage.createFromPdu(( byte []) pdus[i]);
                    msg  +=  messages[i].getMessageBody();
                }
                Toast.makeText(context, msg, Toast.LENGTH_LONG).show();
            }
        }
    }

} 

 二、读取收件箱中的短信

1.从数据库中读取，URI为"content://sms/inbox" 

import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.widget.TextView;

public class MySMSManager extends Activity {
	private TextView textview;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		textview = (TextView) findViewById(R.id.textview);
		readShortMessage();
	}

	public void readShortMessage() {
		ContentResolver cr = getContentResolver();
		Cursor cursor = cr.query(Uri.parse(" content://sms/inbox "), null,
				null, null, null);
		String msg = "";
		while (cursor.moveToNext()) {
			int phoneColumn = cursor.getColumnIndex(" address ");
			int smsColumn = cursor.getColumnIndex(" body ");
			msg += cursor.getString(phoneColumn) + " : "
					+ cursor.getString(smsColumn) + " \n ";
		}
		textview.setText(msg);
	}
}

2.添加权限 

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

 附：其它短信的URI和数据库表字段 

String SMS_URI_ALL  =   " content://sms/ " ; 
String SMS_URI_INBOX  =   " content://sms/inbox " ;
String SMS_URI_SENT  =   " content://sms/sent " ;    
String SMS_URI_DRAFT  =   " content://sms/draft " ;     
String SMS_URI_OUTBOX  =   " content://sms/outbox " ;    
String SMS_URI_FAILED  =   " content://sms/failed " ;     
String SMS_URI_QUEUED  =   " content://sms/queued " ;  

/*  _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  */ 

三、打开发送短信界面

Uri uri  =  Uri.parse( " smsto:13800138000 " );
        Intent it  =   new  Intent(Intent.ACTION_SENDTO, uri);
        it.putExtra( " sms_body " ,  " The SMS text " );
        startActivity(it); 

 

四、发送短信

1.通过SmsManager的sendTextMessage(destinationAddress, scAddress, text, sentIntent, deliveryIntent)方法发送

String msg  = " hello " ; 
        String number  =   " 1234565678 " ; 
        SmsManager sms  =  SmsManager.getDefault(); 
        PendingIntent pi  =  PendingIntent.getBroadcast( this , 0 , new  Intent(), 0 ); 
        sms.sendTextMessage(number, null ,msg,pi, null ); 

2.添加权限

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

五、直接向数据库写短信

ContentResolver cr  =  getContentResolver();
        ContentValues cv  =   new  ContentValues();
        cv.put( " address " ,  " 13800138000 " );
        cv.put( " body " ,  " hello! " );
        cr.insert(Uri.parse( " content://sms/inbox " ), cv);

权限：

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

 六、监听短信数据库变化

使用ContentObserver ，观察"content://sms"的变化，调用重写的onChange方法，可以监听到短信记录的变化，这样可以监听发短信，同样也是可以监听收短信的。

import android.database.ContentObserver;
import android.os.Handler;
import android.util.Log;

public class SMSObserver extends ContentObserver {
	public SMSObserver(Handler handler) {
		super(handler);
	}

	@Override
	public void onChange(boolean selfChange) {
		Log.i(" sms ", " sms ");
	}

}

然后在Acitivty或Service里注册这个观察者

getContentResolver().registerContentObserver(Uri.parse( " content://sms " ),  true ,  new  SMSObserver( new  Handler()));
