disable rating on RatingBar
<p>I'am using a ratingbar und a OnRatingBarChangeListener in my Code.
The user can rate once and after this I set 
        <code>ratingBar.setEnabled(false)</code> .
I want to show the user an advice why he can't rate anymore.
How can I achieve to set a Toast after the user touch the disabled ratingbar?</p>

<p>Anybody an idea?</p>

<p>greetings  </p>
