Android编程实现拦截短信并屏蔽系统Notification的方法
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-permissionandroid:name="android.permission.RECEIVE_SMS"> </uses-permission> <uses-permissionandroid:name="android.permission.RECEIVE_SMS"> </uses-permission>
3.要写个广播接收类
publicclasssmsreceiveandmaskextendsBroadcastReceiver{
privateStringTAG="smsreceiveandmask";
@Override
publicvoidonReceive(Contextcontext,Intentintent){
}
publicclasssmsreceiveandmaskextendsBroadcastReceiver{
privateStringTAG="smsreceiveandmask";
@OverridepublicvoidonReceive(Contextcontext,Intentintent){}
4.Manifest.xml的receiver标签里要加入intent-filter,action为
<actionandroid:name="android.provider.Telephony.SMS_RECEIVED"/> <actionandroid: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
<receiverandroid:name=".smsreceiveandmask"> <intent-filterandroid:priority="1000"> <actionandroid:name="android.provider.Telephony.SMS_RECEIVED"/> </intent-filter> </receiver> <receiverandroid:name=".smsreceiveandmask"> <intent-filterandroid:priority="1000"> <actionandroid: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
<?xmlversion="1.0"encoding="utf-8"?> <manifestxmlns:android="http://schemas.android.com/apk/res/android" package="com.hwttnet.test.smsreceiveandmask"android:versionCode="1" android:versionName="1.0"> <uses-sdkandroid:minSdkVersion="3"/> <uses-permissionandroid:name="android.permission.RECEIVE_SMS"></uses-permission> <applicationandroid:icon="@drawable/icon"android:label="@string/app_name"> <receiverandroid:name=".smsreceiveandmask"> <intent-filterandroid:priority="1000"> <actionandroid:name="android.provider.Telephony.SMS_RECEIVED"/> </intent-filter> </receiver> </application> </manifest>
<?xmlversion="1.0"encoding="utf-8"?> <manifestxmlns:android="http://schemas.android.com/apk/res/android"package="com.hwttnet.test.smsreceiveandmask"android:versionCode="1"android:versionName="1.0"> <uses-sdkandroid:minSdkVersion="3"/> <uses-permissionandroid:name="android.permission.RECEIVE_SMS"> </uses-permission> <applicationandroid:icon="@drawable/icon"android:label="@string/app_name"> <receiverandroid:name=".smsreceiveandmask"> <intent-filterandroid:priority="1000"> <actionandroid:name="android.provider.Telephony.SMS_RECEIVED"/> </intent-filter> </receiver> </application> </manifest>
BroadcastReceiver类：
packagecom.hwttnet.test.smsreceiveandmask;
importandroid.app.Activity;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.os.Bundle;
importandroid.telephony.SmsMessage;
importandroid.util.Log;
publicclasssmsreceiveandmaskextendsBroadcastReceiver{
privateStringTAG="smsreceiveandmask";
@Override
publicvoidonReceive(Contextcontext,Intentintent){
Log.v(TAG,">>>>>>>onReceivestart");
//第一步、获取短信的内容和发件人
StringBuilderbody=newStringBuilder();//短信内容
StringBuildernumber=newStringBuilder();//短信发件人
Bundlebundle=intent.getExtras();
if(bundle!=null){
Object[]_pdus=(Object[])bundle.get("pdus");
SmsMessage[]message=newSmsMessage[_pdus.length];
for(inti=0;i<_pdus.length;i++){
message[i]=SmsMessage.createFromPdu((byte[])_pdus[i]);
}
for(SmsMessagecurrentMessage:message){
body.append(currentMessage.getDisplayMessageBody());
number.append(currentMessage.getDisplayOriginatingAddress());
}
StringsmsBody=body.toString();
StringsmsNumber=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
booleanflags_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,">>>>>>>onReceiveend");
}
}
希望本文所述对大家Android程序设计有所帮助。
