Does "span" option work?

[Pierre Durand]

If I have 3 columns and I set the "span" option to "2", I have this error:

My code:

        if (convertView == null) {
            LayoutInflater layoutInflator = LayoutInflater.from(getContext());
            convertView = layoutInflator.inflate(R.layout.row_staggered_demo,
                    null);
            StaggeredGridView.LayoutParams layoutParams = new StaggeredGridView.LayoutParams(StaggeredGridView.LayoutParams.WRAP_CONTENT);
            layoutParams.span = 2;
            convertView.setLayoutParams(layoutParams);
            holder = new ViewHolder();
            holder.imageView = (ScaleImageView) convertView .findViewById(R.id.imageView1);
            convertView.setTag(holder);
        }

Currently it is not supported :( Feel free to have at it. A span would look kinda funny anyways no? Anyways its an interesting problem so ill try to take a look at it once i have some free time.

The "span" option is used in the Google+ app :-)

Span works fine in the original com.android.ex.widget version of this, however for some reason in this build, the scroller stuffs up the laying out? It works fine until scroll though.
