title: Disable buttons based on spinner choice
body: <p>So I have <strong>buttons</strong> (not the soft key pad) on the screen but I want some to be <strong>disabled</strong> (can't click) when you pick a certain <strong>spinner option</strong>. Like I have the buttons 0-9 (for numeric input) and if "Base 2" (spinner selection 0) is picked I want all the buttons except 0 and 1 to be disabled.</p>
