Android AlertDialog always exits when I click on OK Button
<p>Is there some way to do validation upon clicking ok. Im not dismissing it but it closes when I click Ok. I have written a custom AlertDialog that uses some edit texts. Problem is I can't validate anything. If validation fails I want to change message and tell user but instead it just closes.  I'm using AlertBuilder</p>

<pre><code>        builder.setPositiveButton(DialogInterface.OnClickListener(){
               @Override
                public void onClick(DialogInterface dialog, int which) {
                  // I don't dismiss here.
                }

           }
</code></pre>
