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>
