Android學習筆記 - 接收SMS訊息(SMSReceiver)

1. 需繼承BroadcastReceiver並覆寫onReceive方法，將所有接收到SMS訊息要處理的動作寫在這個方法內。要接收SMS訊息需要使用者先同意接收SMS訊息的權限，因此需在AndroidManifest.xml允許存取android.permission.RECEIVE_SMS這個權限。

2.SMSReceiver.java

package tw.nicky.ReceiveSMSExample;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;

public class SMSReceiver extends BroadcastReceiver{
 @Override
 public void onReceive(Context context, Intent intent) {
  //判斷這個是接收到SMS的Broadcast
  if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
   Bundle bundle = intent.getExtras();
   Object[] pdus = (Object[]) bundle.get("pdus");
   SmsMessage[] smsMessages = new SmsMessage[pdus.length];
   //將pdu轉成SmsMessage
   for(int i=0;i

3. AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="tw.nicky.ReceiveSMSExample" android:versionCode="1"
 android:versionName="1.0">
 <application android:icon="@drawable/icon" android:label="ReceiveSMSExample">
  <receiver android:name=".SMSReceiver">
   <intent-filter>
    <action android:name="android.provider.Telephony.SMS_RECEIVED" />
   </intent-filter>
  </receiver>
 </application>
 <uses-permission android:name="android.permission.RECEIVE_SMS" />
</manifest>
