Android程式設計實現攔截簡訊並遮蔽系統Notification的方法

NO IMAGE

本文例項講述了Android程式設計實現攔截簡訊並遮蔽系統Notification的方法。分享給大家供大家參考,具體如下:

攔截簡訊有幾個關鍵點:

1.android接收簡訊時是以廣播的方式

2.程式只要在自己的Manifest.xml里加有”接收”SMS的許可權


<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標籤裡要加入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優先順序,以使自己接收到SMS優先於系統或其它軟體


<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.當自己的程式接收到要遮蔽的SMS後,用 this.abortBroadcast();來結束廣播的繼續發給別的程式,這樣系統就不會收到簡訊廣播了,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();}

原始碼如下:

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、獲取簡訊的內容和發件人
StringBuilder body = new StringBuilder();// 簡訊內容
StringBuilder number = new StringBuilder();// 簡訊發件人
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:確認該簡訊內容是否滿足過濾條件
boolean flags_filter = false;
if (smsNumber.equals("10086")) {// 遮蔽10086發來的簡訊
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");
}
}
