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");
}
}
希望本文所述对大家Android程序设计有所帮助。
