Java is case-sensitive, and you've called the method with inaccurate casing. You need to call setOnClickListener().

Hope that helps, let me know if you're still having issues.

P.S. It's a convention in Java to begin local variables with a lowercase letter, and then capitalize the first letter of each subsequent word in the variable name. So it would be more proper if your variable was named newFact. You can read more about naming conventions in the Oracle documentation.
