Android: How to change the textsize in an EditText field?

I want to display a table with some fields being editable - see this example:

<?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="fill_parent"
 android:orientation="vertical"
 android:paddingLeft="1dip"
 android:paddingRight="1dip"
 android:paddingBottom="1dip"
 android:background="#F00"
 >
 <ScrollView
  android:id="@+id/ScrollView01"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:scrollbars="vertical"
  >
  <HorizontalScrollView
   android:id="@+id/HorizontalScrollView01"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:scrollbars="horizontal"
   >
   <TableLayout
    android:id="@+id/ItemPane"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#EEE"
   >
    <TableRow
     android:id="@+id/DataRow"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"    
     android:background="#888"
     android:layout_margin="0dp" 
     android:gravity="left"
     >
     <TextView
      android:id="@+id/NameField"
      android:text="Fieldname"
      android:background="#EEE"
      android:textSize="14dp"
      android:layout_margin="1dp" 
      android:layout_marginBottom="0dp" 
      android:paddingLeft="3dp"
      android:paddingRight="3dp"
     />
     <EditText
      android:id="@+id/DataField"
      android:text="some field"
      android:background="#EEE"
      android:textSize="14dp"
      android:layout_margin="1dp" 
      android:layout_marginBottom="0dp" 
      android:paddingLeft="3dp"
      android:paddingRight="3dp"
      android:singleLine="true"
     />
     <EditText
      android:id="@+id/DataField2"
      android:text="some longish field content..."
      android:background="#EEE"
      android:textSize="14dp"
      android:layout_margin="1dp" 
      android:layout_marginBottom="0dp" 
      android:paddingLeft="3dp"
      android:paddingRight="3dp"
      android:singleLine="true"
     />
    </TableRow>   
   </TableLayout>
  </HorizontalScrollView>
 </ScrollView>
</LinearLayout>

Why is the textSize attribute ignored in EditText-fields? How can I make the text in those fields smaller, so that ALL cells have the same font size? Why does Android not honor that attribute, even if explicitly set?
