SwipeRefreshLayout和RecyclerView使用的小问题

 mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {

            }
        })

//这段代码如果写在onCreate方法中是无效的,因为SwipeRefreshLayout控件还未完全加载,可以使用延迟加载的方法使用下面的代码
mSwipeRefreshLayout.setRefreshing(true);

//延迟加载
        getWindow().getDecorView().post(new Runnable() {
            @Override
            public void run() {
                myHandler.post(new Runnable() {
                    @Override
                    public void run() {                           
                    mSwipeRefreshLayout.setRefreshing(true);
                    }
                });
            }
        });
