5,089 PointsSet the text color of foodLabel to Color.BLUE. Then set the text color of drinkLabel to Color.GRAY. Doesn't Work, Help
I don't know what's wrong, can somebody find the mistake and help me?
import android.app.Activity import android.os.Bundle import android.widget.TextView import android.widget.RelativeLayout
class MealActivity : Activity() { override fun onCreate(savedInstanceState: Bundle) { super.onCreate(savedInstanceState)
setContentView(R.layout.activity_meal)
val foodLabel = findViewById(R.id.foodTextView) as TextView
val drinkLabel = findViewById(R.id.drinkTextView) as TextView
val mealLayout = findViewById(R.id.mealLayout) as RelativeLayout
mealLayout.backgroundColor = Color.RED
foodLabel.setTextColor(Color.BLUE)
drinkLabel.setTextColor(Color.GRAY)
} }
I always get this error: MealActivity.kt:17:15: error: unresolved reference: setTextColor foodLabel.setTextColor(Color.BLUE) ^ MealActivity.kt:18:16: error: unresolved reference: setTextColor drinkLabel.setTextColor(Color.GRAY)

Treehouse TeacherHi there, Alina Pohl ! It looks to me like you're doing pretty well. The biggest hint in this challenge is this line:
mealLayout.backgroundColor = Color.RED
Your two lines that set the textColor should be almost identical including the use of an equals sign as opposed to a pair of parentheses. In this line, they are setting the backgroundColor. Note that it does not use the word "set" as you have in your code. Instead, it just says backgroundColor
. We're looking for the same thing here except with textColor
instead of backgroundColor
.
I feel like you can get it with these hints, but let me know if you're still stuck!
