這只是部分代碼。大家直接拷貝相應代碼到自己的activity里對應位置即可。

public EditText re_check; private BroadcastReceiver smsReceiver; private IntentFilter filter2; private String strContent; private String patternCoder = "(?<!\\d)\\d{6}(?!\\d)";//匹配六位數字的正則表達式 private Handler handler2 = new Handler() {public void handleMessage(android.os.Message msg) {re_check.setText(strContent);};};@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.act_register);re_check = (EditText) findViewById(R.id.re_regcode);init();}private void init() {filter2 = new IntentFilter();filter2.addAction("android.provider.Telephony.SMS_RECEIVED");filter2.setPriority(Integer.MAX_VALUE);smsReceiver = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {Object[] objs = (Object[]) intent.getExtras().get("pdus");for (Object obj : objs) {byte[] pdu = (byte[]) obj;SmsMessage sms = SmsMessage.createFromPdu(pdu);// 短信的內容String message = sms.getMessageBody();// 短息的手機號String from = sms.getOriginatingAddress();if (!TextUtils.isEmpty(from)) {String code = patternCode(message);if (!TextUtils.isEmpty(code)) {strContent = code;handler2.sendEmptyMessage(1);}}}} };registerReceiver(smsReceiver, filter2); }/*** 匹配短信中間的6個數字（驗證碼等）* * @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;}@Overrideprotected void onDestroy() {super.onDestroy();unregisterReceiver(smsReceiver);}
