How can I mix absolute and relative sizes?

Question

I want to create a custom list item. Basically it should 3 areas in a horizontal LinearLayout. The most left one is supposed to be 50dp wide, the right most one as well. I would like the one in the middle to take up the rest of the space. In the end it should be 50px | width - 100px | 50px.

Can I do this in XML?

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearLayout1"
    android:layout_width="fill_parent"
    android:layout_height="100dp"
    android:gravity="right" >

    <FrameLayout
        android:id="@+id/frameLayout1"
        android:layout_width="50dp"
        android:layout_
        android:layout_height="match_parent" 
        android:layout_weight="0">
    </FrameLayout>

    <LinearLayout
        android:id="@+id/linearLayout2"
        android:layout_width="wrap_content"
        android:layout_height="match_parent" 
        android:gravity="fill"
        android:orientation="vertical" 
        android:layout_weight="0">

    </LinearLayout>

    <FrameLayout
        android:id="@+id/frameLayout2"
        android:layout_width="50dp"
        android:layout_height="match_parent"
        android:layout_weight="0" >

    </FrameLayout>

</LinearLayout>

Just set the layout-weight of the middle item to 1. And layout_width to fill_parent.
