Android ListView doesn't expand the whole screen?

I've the following Activity:

 <?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/FiltersLayout" android:orientation="vertical"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    >
    <ScrollView android:id="@+id/FiltersScroll"
        android:orientation="vertical" android:layout_width="fill_parent"
        android:layout_height=开发者_如何转开发"wrap_content"
        android:layout_weight="1">
        <ExpandableListView android:id="@+id/featureList"
            android:layout_width="fill_parent" android:stretchColumns="*" android:orientation="vertical" android:layout_height="fill_parent">

        </ExpandableListView>

    </ScrollView>
</LinearLayout>

I need the ExpandableListView to scratch the screen, but it shows as the following:

Try changing the height of the ScrollView to fill_parent, but really you should omit the ScrollView entirely as a ListView provides its own scrolling.
