How to change the background color?

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(){
          public void onClick(View v){
            TextView.SetText(fact);
            RelativeLayout.setBackgroundColor(Color.GREEN);

    }
};

What kind of error are you getting ? Are you getting an exception?

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);
    }
}
