android parent expandablelistview divider

I want to put divider only between parent elements. When i set 

android:divider="@drawable/divider"
android creates divider between parent elements, but creates divider between child elements too. When i add 
android:childDivider="@color/transparent"
android removes the divider between child elements, but the free space between them remains. Why? I have tried to 
android:dividerHeight="0dp"
but nothing happened.

At all i want to set divider between parent elements, but i do not want any divider or empty space between child elements.

any ideas how to do that??

In order to remove dividers just from the child views and not between the parents in the expandable list:

add android:childDivider="#00000000" in the ExapandableListView attributes in XML:

<ExpandableListView
    android:id="@+id/elv"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:childDivider="#00000000" />
