Android编程实现拦截短信并屏蔽系统Notification的方法_Android

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");
  }
}
