Android编程实现拦截短信并屏蔽系统Notification的方法

本文实例讲述了Android编程实现拦截短信并屏蔽系统Notification的方法。分享给大家供大家参考，具体如下：

拦截短信有几个关键点：

1.android接收短信时是以广播的方式

2.程序只要在自己的Manifest.xml里加有"接收"SMS的权限

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

3.要写个广播接收类

public class smsreceiveandmask extends BroadcastReceiver {
 private String TAG = "smsreceiveandmask";
 @Override
 public void onReceive(Context context, Intent intent) {
}
public class smsreceiveandmask extends BroadcastReceiver {
 private String TAG = "smsreceiveandmask";
 @Overridepublic void onReceive(Context context, Intent intent) {}

4.Manifest.xml的receiver标签里要加入intent-filter ,action为

<action android:name="android.provider.Telephony.SMS_RECEIVED" />
<action android:name="android.provider.Telephony.SMS_RECEIVED" />

5.重要的是要在这个intent-filter上加上priority优先级，以使自己接收到SMS优先于系统或其它软件

<receiver android:name=".smsreceiveandmask" >
     <intent-filter android:priority="1000">  
       <action android:name="android.provider.Telephony.SMS_RECEIVED" />
     </intent-filter>
   </receiver>
<receiver android:name=".smsreceiveandmask" >
<intent-filter android:priority="1000">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>

6.当自己的程序接收到要屏蔽的SMS后，用 this.abortBroadcast();来结束广播的继续发给别的程序，这样系统就不会收到短信广播了，Notification也不会有提示了

// 第三步:取消
if (flags_filter) {
 this.abortBroadcast();
}
// 第三步:取消if (flags_filter) {this.abortBroadcast();}

源码如下：

Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="com.hwttnet.test.smsreceiveandmask" android:versionCode="1"
 android:versionName="1.0">
 <uses-sdk android:minSdkVersion="3" />
 <uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
 <application android:icon="@drawable/icon" android:label="@string/app_name">
   <receiver android:name=".smsreceiveandmask" >
     <intent-filter android:priority="1000">
       <action android:name="android.provider.Telephony.SMS_RECEIVED" />
     </intent-filter>
   </receiver>
 </application>
</manifest>

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.hwttnet.test.smsreceiveandmask" android:versionCode="1"android:versionName="1.0">
<uses-sdk android:minSdkVersion="3" />
<uses-permission android:name="android.permission.RECEIVE_SMS">
</uses-permission>
<application android:icon="@drawable/icon" android:label="@string/app_name">
<receiver android:name=".smsreceiveandmask" >
<intent-filter android:priority="1000">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
</manifest>

BroadcastReceiver类：

package com.hwttnet.test.smsreceiveandmask;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
public class smsreceiveandmask extends BroadcastReceiver {
 private String TAG = "smsreceiveandmask";
 @Override
 public void onReceive(Context context, Intent intent) {
   Log.v(TAG, ">>>>>>>onReceive start");
   // 第一步、获取短信的内容和发件人
   StringBuilder body = new StringBuilder();// 短信内容
   StringBuilder number = new StringBuilder();// 短信发件人
   Bundle bundle = intent.getExtras();
   if (bundle != null) {
     Object[] _pdus = (Object[]) bundle.get("pdus");
     SmsMessage[] message = new SmsMessage[_pdus.length];
     for (int i = 0; i < _pdus.length; i++) {
       message[i] = SmsMessage.createFromPdu((byte[]) _pdus[i]);
     }
     for (SmsMessage currentMessage : message) {
       body.append(currentMessage.getDisplayMessageBody());
       number.append(currentMessage.getDisplayOriginatingAddress());
     }
     String smsBody = body.toString();
     String smsNumber = number.toString();
     if (smsNumber.contains("+86")) {
       smsNumber = smsNumber.substring(3);
     }
     // 第二步:确认该短信内容是否满足过滤条件
     boolean flags_filter = false;
     if (smsNumber.equals("10086")) {// 屏蔽10086发来的短信
       flags_filter = true;
       Log.v(TAG, "sms_number.equals(10086)");
     }
     // 第三步:取消
     if (flags_filter) {
       this.abortBroadcast();
     }
   }
   Log.v(TAG, ">>>>>>>onReceive end");
 }
}
