        android:layout_height="wrap_content"
        android:dropDownWidth="fill_parent"
        android:ems="10"
        android:completionThreshold="1"
        android:dropDownAnchor="@+id/btn"
        android:dropDownSelector="@drawable/btn_selector"/>

private String[] mStrings = { "abbaye de Belloc",
			"Abbaye du Mont des Cats", "Abertam", "Abondance", "Ackawi",
			"Acorn", "Adelost", "Affidelice au Chablis", "Afuega'l Pitu",
