Как растянуть ExpandableListView на весь экран?

Question

Всем привет хочу у Вас спросить как можно растянуть 7-мь ExpandableListView элементов на весь экран. Задавать вручную размер каждого элемента не получаеться на других телефонах размер уходит.

активити activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ExpandableListView
        android:id="@+id/expListView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </ExpandableListView>

</LinearLayout>
