源码片段

public class MainActivity extends Activity {
private BroadcastReceiver smsReceiver;
private IntentFilter filter2;
private Handler handler;
private EditText et;
private String strContent;
private String patternCoder = "(?<!--\\d)\\d{6}(?!\\d)";

@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 et = (EditText) findViewById(R.id.et);
 handler = new Handler() {
  public void handleMessage(android.os.Message msg) {
   et.setText(strContent);
  };
 };
 filter2 = new IntentFilter();
 filter2.addAction("android.provider.Telephony.SMS_RECEIVED");
 filter2.setPriority(Integer.MAX_VALUE);
 smsReceiver = new BroadcastReceiver() {
  @Override
  public 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);
    // 短信的内容
    String message = sms.getMessageBody();
    Log.d("logo", "message  " + message);
    // 短息的手机号。。+86开头？
    String from = sms.getOriginatingAddress();
    Log.d("logo", "from  " + from);
    Time time = new Time();
    time.set(sms.getTimestampMillis());
    String time2 = time.format3339(true);
    Log.d("logo", from + " " + message + " " + time2);
    strContent = from + " " + message;
    handler.sendEmptyMessage(1);
    if (!TextUtils.isEmpty(from)) {
     String code = patternCode(message);
     if (!TextUtils.isEmpty(code)) {
      strContent = code;
      handler.sendEmptyMessage(1);
     }
    }
   }
  }
 };
 registerReceiver(smsReceiver, filter2);
}

@Override
protected void onDestroy() {
 super.onDestroy();
 unregisterReceiver(smsReceiver);
}

/**

 Pattern p = Pattern.compile(patternCoder);
 Matcher matcher = p.matcher(patternContent);
 if (matcher.find()) {
  return matcher.group();
 }
 return null;
