attrs.xml中

使用：

smartRefresh.setHasFixedSize(true);        smartRefresh.setLayoutManager(new LinearLayoutManager(this));        smartRefresh.addItemDecoration(new SimpleSpaceItemDecoration(UiUtil.dip2px(this, 1), RecyclerView.VERTICAL));        smartRefresh.setLoadViewClickListener(VIEW_REFRESH_ERROR, new View.OnClickListener() {            @Override            public void onClick(View view) {                //刷新失败view点击事件                refresh();            }        });        mList = new ArrayList<>();        mList.add("1");        mList.add("2");        mList.add("3");        mList.add("4");        mAdapter = new MyAdapter(R.layout.xxx_item, mList);        smartRefresh.setAdapter(mAdapter);
