Sometimes Header will glitch a little bit in the RecyclerListView

[hydrated]

It only happened in the first time using the listview. Scroll up and down with different header. The top stickyheader works fine. But there would be another header glitch a frame in the middle of listview that suppose not to show a header there. And then keep using listview there would be no glitch at all if the whole listview item was surfed.

It happens with notifyItemRangeChanged too

    RecyclerView.ItemAnimator animator = recyclerView.getItemAnimator();
    if (animator instanceof SimpleItemAnimator) {
        ((SimpleItemAnimator) animator).setSupportsChangeAnimations(false);
    }

Cancel animator from recyclerview will fix this issue.
