title: Android - How do I make this alert dialog scrollable?
body: <p>I am a beginner in android and making my first android app. my 'About' menu item, when clicked shows an AlertDialog with a really long message.
  I have been trying different methods to make it scrollable but I couldn't. I have tried reading different questions on StackOverflow but they didn't work for me. Here is my AlertDialog code.</p>
  <pre><code>AlertDialog.Builder alertDialog = new AlertDialog.Builder(this);  
  alertDialog.setTitle(&quot;Title&quot;);  
  alertDialog.setMessage(&quot;Here is a really long message.&quot;);  
  alertDialog.setButton(&quot;OK&quot;, null);  
  AlertDialog alert = alertDialog.create();
  alert.show();
  </code></pre>
  <p>Can anybody explain to me in detail how to make it scrollable?
  Any help or suggestions would be appreciated!</p>
