CustomDialog - prevent multiple click
<p>Is it possible to use a flag (in the same way as the <code>Intent.FLAG_ACTIVITY_REORDER_TO_FRONT</code>) to prevent displaying of a <code>CustomDialog</code> when we click more than once on a button ? </p>

<p>I don't want to use a <code>boolean</code> value each time i create a new <code>Dialog</code>...</p>
