I'm getting an unknown class 'listener' error when I try to run my funfacts app

Here's the code I'm using. This is only the first of the errors that I'm faced with:

''' final TextView factLabel = (TextView) findViewById(R.id.factTextView); final Button showFactButton = (Button) findViewById(R.id.showFactButton); final View.OnClickListener listener = new View.OnClickListener() { @Override public void onClick(View view) {

            String fact = "";

            Random randomGenerator = new Random();
            int randomNumber = randomGenerator.nextInt(3);

        if (randomNumber == 0) {

            fact = "It's a slow process but quitting won't speed it up";

        }

         else if (randomNumber == 1) {

            fact = "The bigger the mountain, the better the view";

         }

         else if (randomNumber == 2) {

                fact = "The master has failed more times than the beginner has even tried";

          }

         else {
            fact = "There was an error, dude!";
        }




            factLabel.setText(fact);
    };


        showFactButton.setOnClickListener(listener);


};
