Android: How to 'grey out' a radiobutton
<p>Disabling a radiobutton does not 'grey out' the control in the same way as disabling a checkbox.
I was thinking, how difficult would it be to place a semi-transparent black bitmap over the whole radiobutton view, thereby making it appear darker?</p>

<p>Not really sure where to start on this one, any ideas?</p>
