265 PointsChange Android screen background to dark pink
Can someone tell me what's wrong with my code to change the background color? <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@android:color/#fff092b0" >
<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:textColor="@android:color/white" android:textSize="72sp" />

Change "@android:color/#fff092b0" inside RelativeLayout to "#fff092b0".
android:background="#fff092b0"
The android prefix should only be used when you're accessing certain system colors likwe "white", "black" etc.

265 PointsThanks! That worked, but why are system colors so different? You mean I can't say android:background="#ffffffff"?

10,365 PointsHey there,
android:background="#ffffffff"
would work fine. To use the system white color you need:
android:background="@android:color/white"
I think that you are referencing to a system resource variable by typing @android:color and "white" is the name of the system resourse of the color #ffffffff.
