activity中注册广播，并把验证码显示出来：

private void initBroastcast() {
// TODO Auto-generated method stub
IntentFilter intentFilter= new IntentFilter();
intentFilter.addAction(SMSBroadcastReceiver.SMS_RECEIVED_ACTION);
intentFilter.setPriority(Integer.MAX_VALUE);
mSMSBroadcastReceiver = new SMSBroadcastReceiver();
this.registerReceiver(mSMSBroadcastReceiver, intentFilter);

mSMSBroadcastReceiver.setOnReceivedMessageListener(new SMSBroadcastReceiver.MessageListener() {
@Override
public void onReceived(String message) {

reg_tel_code.setText(message);
// tt.showLongToast(RegActivity.this, message);
}
});
}

注意，注销广播；

@Override
protected void onDestroy() {
super.onDestroy();
//注销短信监听广播
this.unregisterReceiver(mSMSBroadcastReceiver);
}

另外，一定不要忘记xml配置中读取短信权限：

<!-- get短信-->
<uses-permission android:name="android.permission.RECEIVE_SMS" ></uses-permission>
<uses-permission android:name="android.permission.READ_SMS" > </uses-permission>
