Prevent AlertDialog from closing
<p>I have a custom AlertDialog with a bunch of checkboxes. I want to prevent the AlertDialog from closing if none of the checkboxes are selected. Is this possible?</p>

<p>I know I can close momentarily and re-open it, but I would rather not do this as I have some code within the setPositiveButton which I do not want to repeat. </p>

<p>Thanks.</p>
