看到了Android版知乎实现了这种效果，就自己也实现了一下。

先来一张效果图

实现方式：

方法一：

①在onWindowFocusChanged()方法中，设置为刷新状态为true

@Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); mSwipeRefreshLayout.setRefreshing(true); }

②在获取数据完成后设置刷新状态为false

if (mSwipeRefreshLayout.isRefreshing()) { mSwipeRefreshLayout.setRefreshing(false); }

方法二：

①调用mSwipeRefreshLayout.measure()方法后，设置刷新状态为true

//手动调用,通知系统去测量 mSwipeRefreshLayout.measure(0,0); mSwipeRefreshLayout.setRefreshing(true);

②在获取数据完成后设置刷新状态为false

if (mSwipeRefreshLayout.isRefreshing()) { mSwipeRefreshLayout.setRefreshing(false); }

说明：
方法一和方法二的第一步的目的，都是为了在SwipeRefreshLayout绘制完成之后，再设置刷新状态为true，否则大多数情况下，SwipeRefreshLayout刷新球会不显示。
