看到了Android版知乎實現了這種效果，就自己也實現了一下。
先來一張效果圖
實現方式：
方法一：
①在onWindowFocusChanged()方法中，設置為刷新狀態為true
@Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); mSwipeRefreshLayout.setRefreshing(true); }②在獲取數據完成后設置刷新狀態為false
if (mSwipeRefreshLayout.isRefreshing()) { mSwipeRefreshLayout.setRefreshing(false); }方法二：
①調用mSwipeRefreshLayout.measure()方法后，設置刷新狀態為true
//手動調用,通知系統去測量 mSwipeRefreshLayout.measure(0,0); mSwipeRefreshLayout.setRefreshing(true);
②在獲取數據完成后設置刷新狀態為false
if (mSwipeRefreshLayout.isRefreshing()) { mSwipeRefreshLayout.setRefreshing(false); }說明：
方法一和方法二的第一步的目的，都是為了在SwipeRefreshLayout繪制完成之后，再設置刷新狀態為true，否則大多數情況下，SwipeRefreshLayout刷新球會不顯示。
