Take care of the comment in getItemOffsets(...).

usage Example :

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        mRecyclerView.addItemDecoration(
                new DividerItemDecoration(getResources().getDrawable(R.drawable.list_divider, getActivity().getTheme())));
    } else {
        mRecyclerView.addItemDecoration(new DividerItemDecoration(getResources().getDrawable(R.drawable.list_divider)));
    }
