Android L first item only reordering problem related to visibility

[chanil1218]

In Latest commit example project at Android L device, only first item reordering cause sporadic item disappearance.

And in our project, long click on first item doesn't make selectedView(first item) invisible at startDragAtPosition(int position) method.
I think these two incidents related.
But I can't debug it.

Any idea?

My problem was notifyDataSetChanged.
