smartrefresh.setOnRefreshListener(new OnRefreshListener() {
    @Override

        smartrefresh.finishRefresh();//時間
        initData();//資料
    }
});
smartrefresh.setOnLoadmoreListener(new OnLoadmoreListener() {
    @Override
    public void onLoadmore(RefreshLayout refreshlayout) {
   smartrefresh.finishLoadmore();
