I want to create a scrollable dialog box?

Possible duplicate:
Adding a vertical scrollbar to AlertDialog on Android?

There is a button in my project. When I click on one button, it shows a dialog box with a description of that button. I wrote a description in string.xml c. whenever I click the button, it extracts the description from the string.xml file and shows us. But my problem is that my message (which will be displayed in the dialog box) is too long. So I want the scrollable field alertdialog.with outside of creating another xml file with, as is possible in java code.
