（十六）短信广播接收

一、需求：当接收到短信到来的广播的时候，获得短信的内容和发件人

二、SmsReceiver.java文件如下所示：

package com.example.smslistenerreiceiver;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;
import android.telephony.gsm.SmsManager;
import android.util.Log;

public class SmsReceiver extends BroadcastReceiver {

    private static final String TAG = "SmsReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        Log.i(TAG, "短信来了");
        Object [] pdus = (Object[]) intent.getExtras().get("pdus");
        
        for(Object pdu :pdus){
            SmsMessage sms = SmsMessage.createFromPdu((byte[]) pdu);
            String sender = sms.getOriginatingAddress();
            String body = sms.getMessageBody();
            Log.i(TAG, "发件人："+sender);
            Log.i(TAG, "短信内容："+body);
            
            if("5566".equals(sender)){
                SmsManager sm = SmsManager.getDefault();
                sm.sendTextMessage(sender, null, "短信", null, null);
            }
        }
    }
}

三、注意添加接收短信的权限

 <uses-permission android:name="android.permission.RECEIVE_SMS" />

四、注册监听广播事件

<receiver android:name=".SmsReceiver" >
            <intent-filter android:priority="2147483647" >
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>
