Assuming that you want spacing between the parents, but not between parent & child. I have failed to find a proper way of achieving it. So I did a not a smart fix, by not setting the divider height, instead since I had a custom layout for every parent item, I added a LinearLayout with a fixed height of 25dp at the top of my custom parent layout, as a result I could achieve the desire functionality, but there was a side effect , when you touch the list item, the spacing as well as the list item both are highlighted on touch.
