When add a header view that can't be selected, the first item view attached with the parent view can't be clicked.

When I use this StaggeredGridView, I found several problems. And one of them is pretty serious, please check it. #164

Try to change your code:

@Override
public void onItemClick( AdapterView<?> parent, View view, int position, long id ) {
    int realPos = position - gridView.getHeaderViewsCount();

Thanks for the help, I've already solved the problem. It's an AndroidStaggeredGrid bug. Please see this: #164 the second comment.
