Recyclerview contents overlap scrolling Appbar after implementing SwipeRefreshLayout

Question

I have a recyclerview with scrolling appbar, everything work as expected until swiperefresh layout is implemented. The contents of recyclerview overlap appbar as the image below. don't know what is wrong. Without swiperfresh layout, recyclerview can stay below the appbar.
