Altezza half fill_parent xml

Question

Come posso fare con LinearLayout altezza mezza fill_parent in xml?

<LinearLayout android:layout_width="fill_parent" 
       android:layout_height="fill_parent" 
       android:weightSum="1"> 
     <ImageView android:layout_height="fill_parent" 
       android:layout_width="0dp" 
       android:layout_weight="0.5"/> 
</LinearLayout> 

Mi piacerebbe fare qualcosa di simile con l'altezza.
