android四大组件之BroadcastReceiver短信拦截功能

首先我们要配置一些清单文件

<receiver android:name="com.example.smslinser.MyReceiver" >
            <intent-filter android:priority="1000">
                <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
            </intent-filter>
        </receiver>

过滤器代表短信过滤

然后还要配置优先级，这个范围是从-1000到1000，我们要做拦截功能必须保证我们写的短信接受者，在系统的短信接受者前接收到

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

package com.example.smslinser;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;

public class MyReceiver extends BroadcastReceiver {
    public MyReceiver() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.
        Bundle bundle = intent.getExtras();
        //得到接收的短信,这么设计的目的是为了发送很长的时候能够接收
        Object[] object = (Object[]) bundle.get("pdus");
        for (int i = 0; i < object.length; i++) {

            SmsMessage smsMessage = SmsMessage.createFromPdu((byte[])object[i]);
            //得到发信人号码
            String address = smsMessage.getOriginatingAddress();
            //得到信息内容
            String body = smsMessage.getMessageBody();
            if(address.equals("138")){
                //不让其他的广播接收者接收
                abortBroadcast();
            }
            System.out.println("address:"+address+"body:"+body);

        }

    }
}
