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");  }}
