cannot convert randomNumber into text fact

here is my code so far

import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.Button; import android.widget.TextView;

import java.util.Random;

public class FunFactsActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fun_facts);

    //declare our view variables and assign the views from the layout files
    final TextView factLabel = (TextView) findViewById(R.id.factTextView);
    Button showFactButton = (Button) findViewById(R.id.showFactButton);
    View.OnClickListener listener = new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            // the button was clicked, it will update the with some new facts

            String fact = "";
            // Randomly select a fact

            Random randomGenerator = new Random(); //construct a new Random generator
            int randomNumber = randomGenerator.nextInt(3);

            /* convert randomNumber in a text fact
             * 0 = Ants stretch when they wake up in the morning
             * 1 = Ostriches can run faster than horses
             * 2 = Olympic Gold metals are usually made mostly of silver
             */
            // if randomNumber equals to zero then

            if (randomNumber == 0) {
                // set fact equals to ants fact
                fact = "Ants stretch when they wake up in the morning";
            }
            else if (randomNumber == 1) {
                fact = "Ostriches can run faster than horses";
            }
            else if (randomNumber == 2) {
                fact = "Olympic Gold metals are usually made mostly of silver";
            }
            else {
                fact = "Sorry there was an error";
            }

            // update the label with our dynamic fact
            factLabel.setText(fact);
        }

    };
    showFactButton.setOnClickListener(listener);
