Guys please look at the example project, you need to properly implement View more = getExpandToggleButton(parent); View itemToolbar = getExpandableView(parent);

If these methods return null you will get this exception. If you are using a subclass of AbstractSlideExpandableListAdapter then please use the appropiate ids. Again look at the example.
