Android listview inside relative layout

Question

Have somebody implemented ExpandableListView inside layout? I'm trying to do it and I have problems with height. I want to make it "wrap_content" in order to see fully expanded View when it is expanded. But unfortunately with "wrap_content" parameter I cannot achieve this result. Can somebody help?

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent" >

<ScrollView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

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

<TextView
    android:id="@+id/user"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:layout_alignParentTop="true"
    android:layout_below="@+id/rl"
    android:layout_toRightOf="@+id/user"
    android:paddingLeft="3dp"
    android:text="Top User"
    android:textColor="#000000"
    android:textSize="22dp" />

<ExpandableListView
    android:id="@+id/elvMain"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/user"
    android:layout_above="@+id/about" >
</ExpandableListView>

<TextView
    android:id="@+id/about"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:layout_alignParentBottom="true"
    android:text="Bottom About"
    android:textColor="#6f6f6f"
    android:textSize="24dp"
    android:textStyle="bold" />
</RelativeLayout>
</ScrollView>
    </RelativeLayout>

Group row in ExpandableListView:

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

  <TextView android:id="@+id/groupname"
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:textStyle="bold"
  android:textSize="20dp"
  android:paddingLeft="40dp"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:minHeight="?android:attr/listPreferredItemHeight"
  android:textAppearance="?android:attr/textAppearanceLarge"
  android:background="@drawable/expanded_upper_selector"
  android:gravity="center_vertical"/>

Child Row:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/ingredients_selector">



<TextView android:id="@+id/ingredients_second_layer_text"
     android:textStyle="bold"
     android:textSize="20dp"
     android:paddingLeft="50dp"
     android:paddingRight="50dp"
     android:textColor="@color/dark_orange"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:minHeight="?android:attr/listPreferredItemHeight"
     android:textAppearance="?android:attr/textAppearanceLarge"
     android:gravity="center_vertical"/>
