how do you change text colour from black to white?

The current layout has black text on a white background. Let's change the text color to be white. You will need to add the android:textColor attribute, and copy/paste the Android white value from the RelativeLayout's android:background attribute.

activity_main.xml 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:background="@android:color/white" >
  android:textcolor="@android:color/white" >

  <TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="Treehouse loves me!"
    android:textSize="72sp" />
    android:textcolor="@android:color/white" >

</RelativeLayout>

Some hints for task 1

  • You will only be adding the attribute to the TextView
  • The C in textColor is uppercase
  • Check your closing angle bracket (you have two - the one you need is missing a slash)
  • Use the syntax coloring to identify errors
