Why is Android WebView refusing user input?

I'm developing an Android application that uses a WebView to display the login page for Facebook. The page loads beautifully, and I'm able to select the username/password textboxes, but typing in them will not work. That is, they definitely have input focus (they have the orange focus highlight box and a flashing cursor), but typing in them does absolutely nothing. I'm not certain, but I think maybe the form buttons are also playing up - they appear to be simply refreshing the page, rather than submitting the form.

Just to be clear, although I'm particularly interested in getting Facebook running, I'm sure that this isn't a Facebook issue since other websites (Google, etc) also display the same behavior.

Does anyone have any ideas what might be the issue?

Turns out that it was apparently the WebView not having focus that was the issue.

I discovered that using the arrow keys to get focus on the textboxes caused them to work, so I theorised that there was an issue somewhere with something not having focus, most likely the WebView not having focus. Sure enough, adding the following line seemed to fix the problem:

webView.requestFocus(View.FOCUS_DOWN);

I'm still at a loss to explain exactly why the issue occurred in the first place - the textboxes should work whether they receive focus from being tapped upon or through being "arrowed" to - but at least I have a solution that appears to work.

Thanks for your input wf.
