Force an ExpandableListView to move other items down

My layout is a ScrollView with some TextView and other controls and also an ExpandableListView.

What I want to do is When Expanding the ExpandableListView the controls which are below it move down and again upon collapsing, all the controls move up and only Group of Expendables become Visible.

The problem is when using wrap_content for expandView's Height the expanding of it shows nothing and just the indicator (little arrow) shows that it's expanded, and when explicitly use some numbers eg. 200dp, the lowest items of expandView not shown. (Because of using two Scrolling widget together).

Here's my simplified layout.

<ScrollView
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:ignore="HardcodedText" >
    <LinearLayout>
       //some controls
    </LinearLayout>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <ExpandableListView
            android:id="@+id/lstDrugs"
            android:layout_width="match_parent"

//HERE is the point that wrap_content only shows the groups header

            android:layout_height=**"wrap_content"**
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:divider="@drawable/dividergradient"
            android:dividerHeight="2dp" >
        </ExpandableListView>

        <Button
            android:id="@+id/btnAddDrug"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/lstDrugs"
            android:text="Add" />
    </RelativeLayout>
</LinearLayout>

I've just found my answer in this thread.

The problem is with using List inside ScrollView. To handle it you should use a layout other than the ScrollView (eg. LinearLayout) and add other widgets as Header and Footer of the list. This would enable the scrolling of the view and also expanding of the List.
