How to apply different colors for gridview row items in android?

I have a grid view with two columns. I want to set different colors for the grid view row items. For example, I want 4 colors to be applied after every 4th row item, alternately. 

android:background="@color/dividerColor"/>
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1.6"
    android:padding="8dp">
    <GridView
        android:id="@+id/gridCategory"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:numColumns="2"
        android:verticalSpacing="10dp"
        android:horizontalSpacing="10dp"
        android:stretchMode="columnWidth"
        android:gravity="center">
    </GridView>
</LinearLayout>
