How to read from barcode scanner

Question

I have an Activity where the user can read some barcodes with a barcode scanner (think on it like a hardware keyboard), which sends a string (usually full of numbers) and a CR symbol at the end (an "enter", we could say). When I read this CR symbol, I have to open a dialog and do some stuff on it with the received string.

The questions are:

How can I listen the string received form the barcode scanner without writing it on an EditText? I mean, since the barcode scanner is like a hardware keyboard, writing the string on a hidden EditText and then listen for the CR symbol could be a solution, but there has to be a more elegant way...
How can I listen to the CR symbol and how could I difference it from the string full of numbers?

I've taken a look at the Handling Keyboard Actions tutorial, but I think it doesn't fit my needs.

Any idea?

Why not read it into a string and then process the string? Post some code so we can help. — ServerMonkey, Jul 22 '15 at 09:02
I don't have any code related yet, sorry. I'm thinking about how to do it before coding it :) — moictab, Jul 22 '15 at 09:04

Have you looked at the Zxing library: https://zxingnet.codeplex.com/

This might help as well, you notice some example storing the results in a string for processing: How to read barcodes with the camera on Android?
