要做一个自动短信回复,所以需要拦截系统短信.

1.在Manifest.xml里加"接收"SMS的权限

<uses-permission android:name="android.permission.RECEIVE\_SMS"></uses-permission>

2.在Manifest.xml里注册一个receive

<receiver android:name=".AutoSMS" android:exported="false">  
<intent-filter android:priority="1000">  
<action android:name="android.provider.Telephony.SMS\_RECEIVED"/>  
</intent-filter>  
</receiver>

3.定义一个短信接收类,并且重写onReceive

//继承BroadcastReceiver  
public class AutoSMS extends BroadcastReceiver  
\{

private String TAG="AutSMS";  
//广播消息类型  
public static final String SMS\_RECEIVED\_ACTION = "android.provider.Telephony.SMS\_RECEIVED";  
//覆盖onReceive方法  
@Override  
public void onReceive(Context context, Intent intent)  
\{

下面是完整的代码:

Manifest.xml:

< manifest  xmlns:android ="http://schemas.android.com/apk/res/android"   
package ="com.xxh.autosms"   
android:versionCode ="1"   
android:versionName ="1.0"  >  
  
< uses-sdk  
 android:minSdkVersion ="8"   
android:targetSdkVersion ="15"  />  
< uses-permission  android:name ="android.permission.RECEIVE\_SMS" />  
  
< application  
 android:icon ="@drawable/ic\_launcher"   
android:label ="@string/app\_name"   
android:theme ="@style/AppTheme"  >  
< activity  
 android:name =".MainActivity"   
android:label ="@string/title\_activity\_main"  >  
< intent-filter >  
< action  android:name ="android.intent.action.MAIN"  />  
  
< category  android:name ="android.intent.category.LAUNCHER"  />  
</ intent-filter >  
</ activity >  
  
< receiver  android:name =".AutoSMS"  android:exported ="false" >  
< intent-filter  android:priority ="1000" >  
< action  android:name ="android.provider.Telephony.SMS\_RECEIVED" />  
</ intent-filter >  
</ receiver >  
  
</ application >  
  
</ manifest >

AutoSMS.java:

package com.xxh.autosms;  
  
import java.text.SimpleDateFormat;  
import java.util.Date;  
  
import android.content.BroadcastReceiver;  
import android.content.Context;  
import android.content.Intent;  
import android.os.Bundle;  
import android.telephony.SmsMessage;  
import android.util.Log;  
import android.widget.Toast;  
  
// 继承BroadcastReceiver   
 public class AutoSMS extends BroadcastReceiver  
\{  
  
private String TAG="AutSMS";  
// 广播消息类型   
 public static final String SMS\_RECEIVED\_ACTION = "android.provider.Telephony.SMS\_RECEIVED";  
// 覆盖onReceive方法   
 @Override  
public void onReceive(Context context, Intent intent)  
\{  
//  TODO Auto-generated method stub   
 Log.i(TAG, "引发接收事件");  
// StringBuilder body=new StringBuilder(""); // 短信内容  
 // StringBuilder sender=new StringBuilder(""); // 发件人  
 // 先判断广播消息   
 String action = intent.getAction();  
if (SMS\_RECEIVED\_ACTION.equals(action))  
\{  
// 获取intent参数   
 Bundle bundle=intent.getExtras();  
// 判断bundle内容   
 if (bundle!= null)  
\{  
// 取pdus内容,转换为Object\[\]   
 Object\[\] pdus=(Object\[\])bundle.get("pdus");  
// 解析短信   
 SmsMessage\[\] messages = new SmsMessage\[pdus.length\];  
for( int i=0;i<messages.length;i++)  
\{  
byte\[\] pdu=( byte\[\])pdus\[i\];  
messages\[i\]=SmsMessage.createFromPdu(pdu);  
\}  
// 解析完内容后分析具体参数   
 for(SmsMessage msg:messages)  
\{  
// 获取短信内容   
 String content=msg.getMessageBody();  
String sender=msg.getOriginatingAddress();  
Date date = new Date(msg.getTimestampMillis());  
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");  
String sendTime = sdf.format(date);  
// TODO:根据条件判断,然后进一般处理   
 if ("10060".equals(sender))  
\{  
//  屏蔽手机号为10060的短信，这里还可以时行一些处理，如把这个信息发送到第三人的手机等等。  
 // TODO:测试   
 Toast.makeText(context, "收到10060的短信"+"内容:"+content, Toast.LENGTH\_LONG).show();  
// 对于特定的内容,取消广播   
 abortBroadcast();  
\}  
else  
\{  
Toast.makeText(context, "收到:"+sender+"内容:"+content+"时间:"+sendTime.toString(), Toast.LENGTH\_LONG).show();  
\}  
\}  
  
\}  
\} // if 判断广播消息结束   
 \}  
  
\}
