    @Inject
    public ExpandableAdapter() {
        super(null);
    }
}

• Instance expandable module for adapter.

public class ExpandableModule extends ExpandableRecyclerViewModule<GroupView, ChildView> {

    public ExpandableModule(List<? extends ExpandableGroup> expandableGroups) {
        super(expandableGroups);
    }

    @Override
    public GroupView onCreateGroupViewHolder(ViewGroup viewGroup, int groupViewType) {
        return GroupView.create(viewGroup);
    }

    @Override
    public ChildView onCreateChildViewHolder(ViewGroup viewGroup, int childViewType) {
        return ChildView.create(viewGroup);
    }
}

• Attach module to adapter.

ExpandableAdapter adapter = new ExpandableAdapter();

ExpandableGroup<String> group1 = new ExpandableGroup<>("group1");
group1.add("item1", false);
group1.add("item2", false);
group1.add("item3", false);

List<String> groupItems2 = new ArrayList<>();
groupItems2.add("item1");
groupItems2.add("item2");
groupItems2.add("item3");
groupItems2.add("item4");
groupItems2.add("item5");
ExpandableGroup<String> group2 = new ExpandableGroup<>("group2", groupItems2);

List<ExpandableGroup<String>> groups = new ArrayList<>();
groups.add(group1);
groups.add(group2);

ExpandableModule mainModule = new ExpandableModule(groups);

adapter.setRecyclerViewModule(module);

recyclerView.setAdapter(adapter);

##Customize.

public int getChildViewType(int groupPosition, int childPosition) {
    return 0;
}
