Height half fill_parent xml

问题:

How I can do with LinearLayout height half 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>

I would like do something similar with height.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:weightSum="2"
    android:orientation="vertical" >

    <LinearLayout android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="#192832"></LinearLayout>

    <LinearLayout android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="#193222"></LinearLayout>


</LinearLayout>

Two linear layouts occupying half of the screen each.
