public void onReceive(Context context, Intent intent) {
        System.out.println("拦截短信");
        String action = intent.getAction();
        if ("android.provider.Telephony.SMS_RECEIVED".equals(action)) 
        {
            Bundle bundle = intent.getExtras();
            Object[] msgs = (Object[]) bundle.get("pdus");
            if (msgs != null) {
                for (Object msg : msgs) {
                    SmsMessage smsMsg = SmsMessage.createFromPdu((byte[]) msg);
                    String phoneNumber = smsMsg.getOriginatingAddress();
                    //去86
                    if(phoneNumber.length()  > 11){
                        phoneNumber = phoneNumber.substring(phoneNumber.length() - 11);
                    }
                    System.out.println("拦截消息"+ContactAdapter.messageFilterMap.keySet().contains(phoneNumber));
                if (ContactAdapter.messageFilterMap.keySet().contains(phoneNumber)) {
                    this.abortBroadcast();
                    }
                    System.out.println(smsMsg.getOriginatingAddress() + " "
                            + smsMsg.getMessageBody() + " "
                            + smsMsg.getIndexOnIcc());
                }
