Help on FunFacts relativeLayout

Help, final RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.relativeLayout); is not working...relativeLayout is showing red.

package com.example.muhammadmumu.funfacts;

import android.os.Bundle; import android.app.Activity; 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; import android.widget.RelativeLayout; import android.widget.Toast;

public class FunFactsActivity extends Activity {

public static final String TAG = FunFactsActivity.class.getSimpleName();

private FactBook mFactBook = new FactBook();
private ColorWheel mColorWheel = new ColorWheel();


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

    // Declare our View variables and assign the view from the layout file
    final TextView factLabel = (TextView) findViewById(R.id.factTextView);
    final Button showFactButton = (Button) findViewById(R.id.showFactButton);
    final RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.relativeLayout);

    Button showfactButton = (Button) findViewById(R.id.showFactButton);
    View.OnClickListener listener = new View.OnClickListener() {
        @Override
        public void onClick(View View) {
        String fact = mFactBook.getFact();
        //Update the label with our dynamic fact
          factLabel.setText(fact);

          int color = mColorWheel.getColor();
          relativeLayout.setBackgroundColor(color);
          showFactButton.setTextColor(color);

        }
    };
    showfactButton.setOnClickListener(listener);

    // Toast.makeText(this, "Yay! Our activity was created!.", Toast.LENGTH_LONG).show();
    Log.d(TAG, "We're logging from the onCreate() method!");


}

}
