Code Challenge Android App Development mealLayout

I don't feel like I have enough information to finish this challenge. Here is my code. How do I stop getting an error related to the OnClickListener(); Unlike Fun Facts I don't know the variable names for the food and drink call.

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);

        View.OnClickListener listener = new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                    foodLabel = setText("");
                    drinkLabel = setText("");
                    mealLayout.setBackgroundColor(Color.GREEN);

            }
        };
    }
}

Hi Nancy,

I believe the task is to just change the background color of the RelativeLayout to green.

So, all you need to do is add (there is no need to create a clicklistener for this exercise):

mealLayout.setBackgroundColor(Color.Green);

I hope this helps, if not please let me know.
