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" >

  <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" />

</RelativeLayout>

This one is pretty much "paint by numbers". Just follow the instructions exactly:

  • You will need to add the android:textColor attribute,
  • and copy/paste the Android white value from the RelativeLayout's android:background attribute.
    android:textColor="@android:color/white"
