I don't think you want the MealLayout to be capitalised ... I've added a comment to you code.

You've also changed some of the other code. That needs changing back. It should look like:

import android.os.Bundle;
import android.widget.TextView;

public class MealActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_meal);

        TextView foodLabel = (TextView) findViewById(R.id.foodTextView);
        TextView drinkLabel = (TextView) findViewById(R.id.drinkTextView);
        RelativeLayout mealLayout = (RelativeLayout) findViewById(R.id.mealLayout);
        mealLayout.setBackgroundColor(Color.GREEN);
    }
}
