Android开发实现短信拦截功能

释放双眼,带上耳机,听听看~!

 

要点

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

<!-- 注册Receiver,并且设置优先级 -->
<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)
{
.....

实例
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>
<!-- 注册Receiver,并且设置优先级 -->
<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
}
}
