SwipeRefreshLayout如何自动刷新

之前试了N种方法都不行，原来是需要调用handler.postDelayed方法才能出现动画效果。

而且SwipeRefreshLayout.setRefrehing(true)不会触发下拉的业务。

SwipeRefreshLayout.OnRefreshListener refreshListener  = new SwipeRefreshLayout.OnRefreshListener() {    @Override    public void onRefresh() {        //下拉业务    }};swipeRefreshLayout.setOnRefreshListener(refreshListener);new Handler().postDelayed(new Runnable() {    @Override    public void run() {        swipeRefreshLayout.setRefreshing(true);        refreshListener.onRefresh();    }}, 100);
