android 通过广播获取指定联系人短信内容

在配置文件中添加以下权限

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

new一个新的广播SMSBroadcast

package aviationboss.broadcast;



import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.os.Bundle;

import android.os.Message;

import android.telephony.SmsMessage;

import android.util.Log;

import aviationboss.activity.PaymentActivity;



/*

 * 判断是否接收到验证信息，并获取验证码

 */

public class SMSBroadcast extends BroadcastReceiver {



    @Override

    public void onReceive(Context arg0, Intent arg1) {

        // TODO Auto-generated method stub

        Log.i("lwx", "receive sms");

        Bundle bundler = arg1.getExtras();//获取所拦截的短信

        if(bundler!=null){

            StringBuilder body = new StringBuilder();

            StringBuilder number = new StringBuilder();

            Object[] _pdus = (Object[]) bundler.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 sm:message){

                body.append(sm.getDisplayMessageBody());

                number.append(sm.getDisplayOriginatingAddress());

            }

            String bodyStr = body.toString();

            String numberStr = number.toString();

            Log.i("lwx", "sms body = "+bodyStr);

            Log.i("lwx", "sms number = "+numberStr);

            if(numberStr.contains("106550101872158437")){//这里判断拦截短信的号码

                try{

                    int index_1 = bodyStr.indexOf("：");

                    int index_2 = bodyStr.indexOf("；");

                    String str = bodyStr.substring(index_1+1, index_2).trim();

                    Log.i("lwx", "str="+str);

                    int count = Integer.parseInt(str);

                    if(count>0){

                        if(PaymentActivity.handler!=null){

                            Message msg = new Message();

                            msg.what = 25;

                            msg.obj = count;

                            PaymentActivity.handler.sendMessage(msg);//将需要的内容发送给activity更新界面

                        }

                    }

                }catch(Exception e){

                    e.printStackTrace();

                }

                

            }

        }

    }

}

配置文件中添加改广播，并设置广播拦截的动作

<receiver android:name="aviationboss.broadcast.SMSBroadcast" >

      <intent-filter>

          <action android:name="android.provider.Telephony.SMS_RECEIVED" />

      </intent-filter>

</receiver>
