RecyclerView的行间距&&RecyclerView的Item间距&&

新建立一个工具类起名SpaceItemDecoration

public class SpacesItemDecoration extends RecyclerView.ItemDecoration {//设置每个Item的间距    private int space;    public SpacesItemDecoration(int space) {        this.space = space;    }    @Override    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {        outRect.left = space;        outRect.right = space;        outRect.bottom = space;        if (parent.getChildAdapterPosition(view) == 0) {            outRect.top = space;        }    }}

当你要使用的时候就要new一个这个出来

使用方法如下

SpacesItemDecoration decoration = new SpacesItemDecoration(16);recyclerViewDelicious.addItemDecoration(decoration);
