use the android:background attribute in your xml. Easiest way if you want to apply it to a whole activity is to put it in the root of your layout. So if you have a RelativeLayout as the start of your xml, put it in here:
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/rootRL" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/background"> </RelativeLayout> If you love us?
