How to set the text color of foodLabel to Color.BLUE and then set the text color of drinkLabel to Color.GRAY.

Hi, I need help to pass this Challenge Task 1 of 1.

Let's continue to add color to MealActivity. In the onCreate() method, set the text color of foodLabel to Color.BLUE and then set the text color of drinkLabel to Color.GRAY.

public class MealActivity extends Activity { public TextView foodLabel; public TextView drinkLabel;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_meal);

    foodLabel.text.setTextColor(Color.BLUE); findViewById(R.id.foodTextView);
    drinkLabel.text.setTextColor(Color.GRAY); findViewById(R.id.drinkTextView);
    RelativeLayout mealLayout = (RelativeLayout) findViewById(R.id.mealLayout);
    mealLayout.setBackgroundColor(Color.GREEN);
}

}

It shows 2 errors

./MealActivity.java:11: cannot find symbol symbol : variable text location: class TextView foodLabel.text.setTextColor(Color.BLUE); findViewById(R.id.foodTextView); ^ ./MealActivity.java:12: cannot find symbol symbol : variable text location: class TextView drinkLabel.text.setTextColor(Color.GRAY); findViewById(R.id.drinkTextView); ^ 2 errors

Thanks in advance.

Hi Beau,

What you've written is correct just that there is no need to add the .text . Also write the new code after mealLayout.setBackgroundColor(Color.GREEN); this line

So instead of
foodLabel.text.setTextColor(Color.BLUE);
drinkLabel.text.setTextColor(Color.GRAY);

it should have been

foodLabel.setTextColor(Color.BLUE); drinkLabel.setTextColor(Color.GRAY); 

public class MealActivity extends Activity {

    public TextView foodLabel;
    public TextView drinkLabel;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_meal);

        foodLabel = (TextView) findViewById(R.id.foodTextView);
        drinkLabel = (TextView) findViewById(R.id.drinkTextView);
        RelativeLayout mealLayout = (RelativeLayout) findViewById(R.id.mealLayout);
        mealLayout.setBackgroundColor(Color.GREEN);

        // Add here
        foodLabel.setTextColor(Color.BLUE);
       drinkLabel.setTextColor(Color.GRAY);  
    }
}

Hope this helps
