Android Reading from an Input stream efficiently

I am making an HTTP get request to a website for an android application I am making.

Stretching a HTML Input Box alongside additional input?

I'm using jQuery on this site, which has form inputs. I'd like one particular field to get longer (width) as the user enters data and space runs out.

Validate field, select or checkbox without form tag

Good day,

I found a lot of topics about that, but, without a proper answer.
