Setting background color of a relativeLayout variable

I have trouble with solving this. The line of code that I have written for this problem does not work, and I can't seem to figure out what the problem is. Hope that someone can help.

  • Hans
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);
        mealLayout.setBackgroundColor(Color.GREEN)

    }
}

Hi Hans,

You have missed the semi-colon at the end of the line. Everything else is fine!
