First header item not displaying

[rupalgoswamidxred]

I integrated your lib for sticky header for reverse layout but first header item not display.

This should return a positive long:

public long getHeaderId(int position)

So use Math.abs() to make it absolute.

I think the author write this:
if (position == 0) {
return -1;
}
in headerAdapter's getHeaderId,
to fit this:
adapter.add("Animals below!");
so, if you do not have a special item, you should remove this:
if (position == 0) {
return -1;
}
