java.lang.ClassCastException: com.example.nearely.Activities.MainActivity cannot be cast to com.github.ksoichiro.android.observablescrollview.ObservableScrollViewCallbacks

Error getting on this line of code:

mRecyclerView.setScrollViewCallbacks((ObservableScrollViewCallbacks) parentActivity);

你这个MainActivity需要实现ObservableScrollViewCallbacks这个接口才可以这样调用吧。
