Run code to click javascript button within Android app? Trying to scrape reply button contact-info on craigslist.org page

I have an app I'm working on which needs to display craigslist ads. I am parsing the html to get the attributes off of the page. But herein lies the problem:

The reply button is a javascript button. In it is the email/phone# for the ad.

I need to get the info from the pane that is generated when the button is clicked and then parse its information.
