Currently, onClick doesn't call super if the item isn't enabled or isViewExpandableOnClick() == false, but this stops any callbacks added to the adapter from being called, which should never be the case if the item is enabled. I think it should be the same as onLongClick().

public void onClick(View view) {
  if (mAdapter.isEnabled(getFlexibleAdapterPosition()) && isViewExpandableOnClick()) {
    toggleExpansion();
  }
  super.onClick(view);
}
