Disable a whole activity from user action
<p>Is there a simple way to disable a user interacting with an activity.
To be done when there is an action running (and a spinning progress bar in the title bar)</p>

<p>EDIT: As it seems I was not clear enough I meant to say: while I already have a spinning progress bar, the user is still able to push any button on the activity, I want to disable the user from being able to do that while the task is running. I do not want to however disable each item on the screen one by one.</p>

<p>Thanks, Jason</p>
