读取短信自动填写验证码功能

//权限

IntentFilter filter = new IntentFilter();

filter.addAction( "android.provider.Telephony.SMS_RECEIVED" );

               for (Object obj : objs) {
                    byte[] pdu = (byte[]) obj;
                    SmsMessage sms = SmsMessage.createFromPdu(pdu);
                    // 短信的内容
                    String message = sms.getMessageBody();
                    Log.d("TAG", "message = " + message);
                    String from = sms.getOriginatingAddress();

                         time.set(sms.getTimestampMillis());
                         String time2 = time.format3339(true);
                         Log.d("TAG", from + "   " + message + "  " + time2);
                         strContent = from + "   " + message;
                         //mHandler.sendEmptyMessage(1);
                         if (!TextUtils.isEmpty(from)) {
                              String code = patternCode(message);
                              if (!TextUtils.isEmpty(code)) {
                                   strContent = code;
                                   mHandler.sendEmptyMessage(1);
                              }
                         }
                    }else {
                         return;
                    }
               }

          }
     };

如果要做读取短信验证码的话

//短信验证码内容 验证码是6位数字的格式

private String strContent;

private String patternCoder = "(?<!\\d)\\d{6}(?!\\d)" ;

/**

      * 匹配短信中间的6个数字（验证码等）

      *

      * @param patternContent

      * @return

      */

     private String patternCode(String patternContent) {

           if (TextUtils.isEmpty(patternContent)) {

               return null ;

          }

          Pattern p = Pattern. compile(patternCoder);

          Matcher matcher = p.matcher(patternContent);

           if (matcher.find()) {

               return matcher.group();

          }

           return null ;

     }

计时功能

//计时重发
     private class TimeCount extends CountDownTimer {
         
        public TimeCount(long millisInFuture, long countDownInterval) {
            super(millisInFuture, countDownInterval);
        }

        @Override
        public void onTick(long millisUntilFinished) {
             mSendButton.setClickable(false);
             mSendButton.setText(millisUntilFinished / 1000 + "秒后重新发送");
        }

        @Override
        public void onFinish() {
             mSendButton.setText("获取验证码");
             mSendButton.setClickable(true);
        }
    }

mTiemTimeCount = new TimeCount(60000, 1000);

mTiemTimeCount .start();
