Spinner with custom background not showing text

I have a pair of Spinners that work exactly as intended, but when I put a drawable on them, the text just dissapears. Here is the XML of both the Layout and the Drawable. The only problem here is that the drawable does not let the text show up.

ttd_list.xml

<?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:orientation="vertical" >
 
 <include
     android:id="@+id/include1"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     layout="@layout/action_bar" />
 
 <LinearLayout
     android:id="@+id/ll1"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:orientation="vertical" android:background="@color/gray">
 
     <RelativeLayout
         android:id="@+id/relativeLayout1"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:descendantFocusability="beforeDescendants"
         android:focusableInTouchMode="true"
         android:paddingBottom="8dip" >
 
         <AutoCompleteTextView
             android:id="@+id/autoCompleteThingsToDo"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:layout_alignParentLeft="true"
             android:layout_marginTop="8dip"
             android:layout_toLeftOf="@+id/buttonSearchThingsToDo"
             android:textColor="#000000" >
         </AutoCompleteTextView>
 
         <Button
             android:id="@+id/buttonSearchThingsToDo"
             style="@style/StandardButton"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:layout_alignParentRight="true"
             android:layout_alignTop="@+id/autoCompleteThingsToDo"
             android:text="@string/search" />
     </RelativeLayout>
 
     <TableRow
         android:id="@+id/tableRow1"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:paddingBottom="8dip" >
 
         <Spinner
             android:id="@+id/spinnerCategories"
             android:layout_width="0dp"
             android:layout_height="wrap_content"
             android:layout_weight="1"
             android:background="@drawable/spinner_filters" />
 
         <View
             android:layout_width="10dip"
             android:layout_height="match_parent" />
 
         <Spinner

             android:layout_weight="1"
             android:background="@drawable/spinner_filters" />
     </TableRow>
 </LinearLayout>
 
 <ListView
     android:id="@+id/listViewThingsToDo"
     android:layout_width="match_parent"
     android:layout_height="0dip"
     android:layout_weight="1" >
 </ListView>
 

spinner_filters.xml

<?xml version="1.0" encoding="utf-8"?>

         <stroke android:color="@color/blue" />
