Here is perfect solution.

to hide the child divider set it color to transparent #00000000

define transparent in your color.xml file

<color name="transparent">#00000000</color>

and then set the child divider

listView.setChildDivider(getResources().getDrawable(R.color.transparent))

or in the layout xml file

<ExpandableListView 
android:layout_width="fill_parent"
android:layout_height="fill_parent" 
android:childDivider="#00000000"/>

here is output :
