MealActivity

I'm getting an error when trying to change to background color to green. Please help.

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.setBackgroundColor(color.GREEN);
}

}

It looks like you're trying to call setBackgroundColor on a variable called relativeLayout. Did you mean to call that on your RelativeLayout named mealLayout? Or do you have another RelativeLayout named relativeLayout? Also, I believe the color needs to be capitalized since you're calling the GREEN static constant in the Color class.

See if the following changes work for you:

RelativeLayout mealLayout = (RelativeLayout)  findViewById(R.id.mealLayout);
mealLayout.setBackgroundColor(Color.GREEN);
