Android LinearLayout Gradient Background

Ok I have managed to solve this using a selector. See code below: main_header.xml: <?xml version=”1.0″ encoding=”utf-8″?> <LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android” android:layout_width=”fill_parent” android:layout_height=”50dip” android:orientation=”horizontal” android:background=”@drawable/main_header_selector”> </LinearLayout> main_header_selector.xml: <?xml version=”1.0″ encoding=”utf-8″?> <selector xmlns:android=”http://schemas.android.com/apk/res/android”> <item> <shape> <gradient android:angle=”90″ android:startColor=”#FFFF0000″ android:endColor=”#FF00FF00″ android:type=”linear” /> </shape> </item> </selector> Hopefully this helps someone who has the same problem.
