本文實例講述了Android編程實現攔截短信并屏蔽系統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里加有"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標簽里要加入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優先于系統或其它軟件
<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后，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。
