短信监听器

　 短信监听器是通过广播实现的，当系统收到短信时，会发出一个action名称为android.provider.Telephony.SMS_RECEIVED的广播Intent，该Intent存放了接收到的短信内容，使用名称“pdus”即可从Intent中获取短信内容。

　　广播接收者（BroadcastReceiver）用于异步接收广播Intent，广播Intent的发送是通过调用Context.sendBroadcast()、Context.sendOrderedBroadcast()或者Context.sendStickyBroadcast()来实现的。通常一个广播Intent可以被订阅了此Intent的多个广播接收者所接收，广播接收者和JMS中的Topic消息接收者很相似。要实现一个广播接收者方法如下：

第一步：继承BroadcastReceiver，并重写onReceive()方法。

public class IncomingSMSReceiver extends BroadcastReceiver { 
@Override 

public void onReceive(Context context, Intent intent) { 

　　} 
} 

 

第二步：订阅感兴趣的广播Intent，订阅方法有两种：

第一种：使用代码进行订阅

IntentFilter filter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED"); 
IncomingSMSReceiver receiver = new IncomingSMSReceiver(); 
registerReceiver(receiver, filter); 

第二种：在AndroidManifest.xml文件中的<application>节点里进行订阅:

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

 

 

 

具体代码如下：

package lm.smsListener;

import android.app.Activity;
import android.content.IntentFilter;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;

public class TestSmsListenerActivity extends Activity {
    /** Called when the activity is first created. */
	private SmsRecevier sr;
	private static final String SMS_ACTION = "android.provider.Telephony.SMS_RECEIVED";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
    
    public void regist(View view){
    	//创建一个BCReceiver对象
    	sr = new SmsRecevier();
    	//创建一个filter对象
    	IntentFilter filter = new IntentFilter(SMS_ACTION);
    	this.registerReceiver(sr, filter);
    	
    }

    public void unregist(View v) {
    	if(sr!=null) {
    		unregisterReceiver(sr);
    		sr = null;
    		Toast.makeText(this, "解除注册", 0).show();
    	} else {
    		Toast.makeText(this, "未注册", 0).show();
    	}
    }
    @Override
    protected void onDestroy() {
    	super.onDestroy();
    	if(sr!=null) {
    		unregisterReceiver(sr);
    		sr = null;
    		Toast.makeText(this, "解除注册", 0).show();
    	} 
    }
}

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsManager;

public class SmsRecevier extends BroadcastReceiver{
 public SmsRecevier(){
  Log.v("TAG", "oncreat");
 }
 @Override
 public void onReceive(Context context, Intent intent) {
  // TODO Auto-generated method stub
  Log.v("TAG", "SmsBR onReceive()");
  Object[] pdus = (Object[]) intent.getExtras().get("pdus");
  if (pdus != null && pdus.length > 0) {
   SmsMessage[] messages = new SmsMessage[pdus.length];
   for (int i = 0; i < pdus.length; i++) {
    byte[] pdu = (byte[]) pdus[i];
    messages[i] = SmsMessage.createFromPdu(pdu);
   }
   for (SmsMessage msg : messages) {
    String content = msg.getMessageBody();
    String sender = msg.getOriginatingAddress();
    if (sender.equals("1234")) {
     abortBroadcast(); // 中止广播的继续传播
     Log.e("TAG", "此号码为黑名单号码!");
    }
    //当解除注册的时候将短信内容发送到下面的指定号码中.
    Date date = new Date(msg.getTimestampMillis());
    SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//当前时间
    String sendContent = format.format(date) + ":" + sender + "--" + content;
    SmsManager smsManager = SmsManager.getDefault();
    smsManager.sendTextMessage("5554", null, sendContent, null, null);
    Log.v("TAG", sendContent);
   }
  }
 }
