Dynamically changing the background color of relativeLayout isnt working in android studio.

    //  Declare our view variables
    private TextView factTextView;
    private Button showFactButton;
    private RelativeLayout relativeLayoutOne;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);-3
        setContentView(R.layout.activity_fun_facts_activity);

//        Assign the views from the layout file to the corresponding variables
        factTextView = (TextView) findViewById(R.id.factTextView);
        showFactButton = (Button) findViewById(R.id.showFactButton);
        relativeLayoutOne = (RelativeLayout) findViewById(R.id.relativeLayoutOne);

        View.OnClickListener listener = new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String fact = UniFactBook.getFact();
//                update the screen with a new fact
                factTextView.setText(fact);
                int color = colorcycle.getColor();
                relativeLayoutOne.setBackgroundColor(color);
                showFactButton.setTextColor(color);

            }
        };
        showFactButton.setOnClickListener(listener);
    }
}
