android - 如何将数据从 BroadcastReceiver 传递到 Activity？

我有一个 BroadcastReceiver 类，它读取传入的 sms 并从 sms 中提取一个 pin。我想将该 sms 传递给用户已经可见的 Activity 。用户应该在 EditText 中输入 pin，我从 EditText 中获取值，将用户输入的 Pin 与 BroadcastReceiver 传递的 Pin 进行比较。如果两者相互匹配，用户可以进入应用程序。但我不知道如何将 BroadcastReceiver 收到的 Pin 传递给 Activity。这是代码

BroadcastReceiver 类

public class IncomingMessage extends BroadcastReceiver {

final SmsManager sms = SmsManager.getDefault();
private OnSMSReceived onSMSReceived = null;

@Override
public void onReceive(Context context, Intent intent) {

    // Retrieves a map of extended data from the intent.
    final Bundle bundle = intent.getExtras();

    try {

        if (bundle != null) {

            String senderNum = null;
            String message = null;
            final Object[] pdusObj = (Object[]) bundle.get("pdus");

            for (int i = 0; i < pdusObj.length; i++) {

                SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                String phoneNumber = currentMessage.getDisplayOriginatingAddress();

                senderNum = phoneNumber;
                message = currentMessage.getDisplayMessageBody();

                Log.i("SmsReceiver", "senderNum: " + senderNum + "; message: " + message);

            }

            if (senderNum.equals("ideamart")) {
                Log.d("MessageIdeaMart", message);

            } else if (senderNum.equals("FindDroid")) {
                if (message.startsWith("Welcome")) {
                    String[] splitArray = message.split(" ");
                    String pin = splitArray[7];
                    Log.d("PIN", pin);

                }
            }
        }
    } catch (Exception e) {
        Log.e("SmsReceiver", "Exception smsReceiver" + e);

    }
}


public void setOnSmsReceivedListener(Context context) {
    this.onSMSReceived = (OnSMSReceived) context;
}


public interface OnSMSReceived {
    void onSMSReceived(String pin);
}
