Stuck on android improving our code challenge...

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.

And this is the code you start with

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);
    }
}

The GRAY needs to be capitalised.

foodLabel.setTextColor(Color.BLUE); drinkLabel.setTextColor(Color.Gray); That's what I put and it worked for me. I hope this helps.

This is what worked for me.

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);
        foodLabel.setTextColor(Color.BLUE);


        drinkLabel = (TextView) findViewById(R.id.drinkTextView);
        drinkLabel.setTextColor(Color.GRAY);

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

Try something like, foodLabel.text.setTextColor(R.Color.BLUE);

Autocomplete will probably assist you too.

I'm opening Eclipse now and will see what I can figure out. What error are you getting?

it just says "There is a compiler error. Please click on preview to view your syntax errors!"

and then in preview it says

./MealActivity.java:16: cannot find symbol symbol : variable Gray location: class Color drinkLabel.setTextColor(Color.Gray); ^ 1 error

I was using = instead of a dot apparently it should have been a two coffee day today.

foodLabel = setTexColor(Color.BLUE); (SNAFU) Oddly enough when I put this foodLabel.setTextColor(Color.BLUE); all is good
