 . It's working fine but when I scroll down my scroll view and trying to go up, it's not going to work, it's not working again. It's refreshing please suggest me How to accomplish this?   
 
 
 Just create a square that  extends   SwipeRefreshLayout  And  override  method  canChildScrollUp () . When you want to scroll down to  ListView , return right.  
 For example,  
  @override boolean canChildScrollUp () {Return Listview.getFirstVisibleItemPostion ()! = 0; }
