Android编程实现拦截短信并屏蔽系统Notification的方法

前端技术 2023/09/02 Android

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。
