Android Question Enabling button when user scrolls down webview until the bottom [Solved]

Why use WebView? It will be simple to do with xCLV.

Thanks for your help, finally I've used an even simpler solution:
I deleted the "I Agree button" and instead I added one sentence at the end of the disclaimer displayed by the webview "IF YOU AGREE WITH ALL THE CONDITIONS click or touch the following text": and then an empty link with text:

"I AGREE"

Then I used the event webview_OverrideUrl to catch the touch.

Cheers
