[안드로이드] RecyclerView - Item 간격

[Step1] ItemDecoration 정의

public class RecyclerViewDecoration extends RecyclerView.ItemDecoration {
    private final int divHeight;

    public RecyclerViewDecoration(int divHeight) {
        this.divHeight = divHeight;
    }

    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        super.getItemOffsets(outRect, view, parent, state);
        outRect.top = divHeight;
    }
}

[Step2] 사용

private void initRecyclerView(ArrayList<CultureSpaceItem> items) {
    recyclerView.setHasFixedSize(true);
    LinearLayoutManager lm = new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false);
    recyclerView.setLayoutManager(lm);
    mAdapter = new RecyclerViewAdapter(getActivity(), items);
    recyclerView.setAdapter(mAdapter);
    recyclerView.addItemDecoration(new RecyclerViewDecoration(25));
}
