android-recyclerview

问题 I am trying to follow a set of statements after the execution of notifyDataSetChanged on a recyclerview. But when I am debugging my application, the debugger reaches the next few lines after my notifyDataSetChanged before going to the onBindViewHolder of the recyclerview's adapter.

问题 I followed this tutorial to implement the behaviors for both hiding the toolbar and the FAB when scrolled: https://mzgreen.github.io/2015/06/23/How-to-hideshow-Toolbar-when-list-is-scrolling(part3)/ I have pasted a demo of what the behavior looks like below.
