Hide divider without hiding childDivider on ExpandableListView

Question

I can't find a way to hide dividers on an ExpandableListView without hiding the child dividers too.

Here is my code.

<ExpandableListView 
            android:id="@+id/activities_list"
            android:background="@android:color/transparent"
            android:fadingEdge="none"           
            android:groupIndicator="@android:color/transparent"
            android:divider="@android:color/transparent"
            android:childDivider="@drawable/list_divider"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />

With this code, I get no dividers on groups but no child dividers neither. If I set android:divider to "@drawable/list_divider" I get both group and child dividers.

Thanks in advance!

The only solution I found is to put the child divider directly into the children XML, this way:

<TextView
    android:id="@+id/name"
    android:layout_centerVertical="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<ImageView android:id="@+id/divider"        
    android:layout_alignParentBottom="true"
    android:layout_width="fill_parent"
    android:layout_height="1dp"
    android:background="@drawable/list_divider" />        

which is very very ugly but works.

But still, there should be a way to do that properly.
