In this challenge you did not need an onClickListener. They just wanted you to change the background color.

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);
    }
}
