Android編程實現攔截短信並屏蔽系統Notification的方法

本文實例講述了Android編程實現攔截短信並屏蔽系統Notification的方法。分享給大家供大家參考，具體如下：

攔截短信有幾個關鍵點：

1.android接收短信時是以廣播的方式

2.程序只要在自己的Manifest.xml裡加有"接收"SMS的權限

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

3.要寫個廣播接收類

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標簽裡要加入intent-filter ,action為

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

5.重要的是要在這個intent-filter上加上priority優先級，以使自己接收到SMS優先於系統或其它軟件

<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.當自己的程序接收到要屏蔽的SMS後，用 this.abortBroadcast();來結束廣播的繼續發給別的程序，這樣系統就不會收到短信廣播了，Notification也不會有提示了

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

源碼如下：

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類：

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、獲取短信的內容和發件人
    StringBuilder body = new StringBuilder();// 短信內容
    StringBuilder number = new StringBuilder();// 短信發件人
    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:確認該短信內容是否滿足過濾條件
      boolean flags_filter = false;
      if (smsNumber.equals("10086")) {// 屏蔽10086發來的短信
        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");
  }
}

希望本文所述對大家Android程序設計有所幫助。
