setBackgroundColor in mealLayout reading error.

Why am i getting an error? When it seems to be correct to me

MealActivity.java 
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);
        RelativeLayout mealLayout.setBackgroundColor(Color.GREEN);
    }


}

Remove the 'RelativeLayout' on the last statement. It should be :

 mealLayout.setBackgroundColor(Color.GREEN);

Once you have declared a view you call it directly.Regards
