4,231 Pointsandroid:background="#FFFFFFFF" doesn't work, although it is literally copy-pasted from Android Studio
Why is it so?
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="@+id/thrustButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/thrust_label"
android:background="#FFFFFFFF"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>

Treehouse TeacherHi there, Taras Kuzyk ! The first part of the question asks you to change the background color, which you're doing, but it's not changing it to the color it asked for. Take a look again at the color value presented in the instructions:
Add an attribute to set its background to #ffaa0000.
The second set of instructions asks you to change the text color to white, which is what you've set the background to now. So you will need a line that starts with this:
android:textColor
I think you can get it with this hint, but let me know if you're still stuck!
