Adding more colors to build a simple app - android

Hi there, I am at the 05:11 mark for the add more colors video and as Ben does I have used my Genymotion emulator to test run the app but have run into a few problems...... I can click my show another fact button to show the red background but then my fun fact disappears and continuing to click does not provide any more colors?

I'm assuming it is due to a relativeLayout id tag issue i.e. when i try to enter the findViewById(R.id.relativeLayout) the lowercase l in relative automatically updates to an upper case L. no matter what I do.

It does this even after I press alt+enter and select the prefill relativeLayout option.

I have even tried changing the id tag to several different options but always get an auto uppercase letter in the first word.

Hope this makes sense as I really want to keep going with learning asap and not get stuck for too long.

Thanks in advance for your help!

this is my code if it helps......

public class FunFactsActivity extends ActionBarActivity { 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 them the views from the layout value
    final TextView factLabel = (TextView) findViewById(R.id.factTextView);
    Button showFactButton = (Button) findViewById(R.id.showFactButton);
    final RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.relativeLayout); /* <---- THIS IS THE R.id.relativeLayout THAT CHANGES TO AN UPPERCASE L. IT CHANGED BACK WHEN I COPY AND PASTED TO HERE */

    View.OnClickListener listener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String fact = mFactBook.getFact();

            int color = mcolorWheel.getColor();
            relativeLayout.setBackgroundColor(Color.RED);

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

        }
    };
    showFactButton.setOnClickListener(listener);

}

}

Its all good I have figured it out myself. Sorry for wasting your time. I just had to sort a couple methods out in my mainActivity.xml
