Setting span size of single row in StaggeredGridLayoutManager

Question

I have a staggered grid that has 2 columns. This is working. What I want is at position 0 for the row to span across the 2 columns. I have done this before quite easily using GridLayoutManger as so:

                mGridLayoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {                     @Override                     public int getSpanSize(int position) {                         return position == 0 ? 2 : 1;                     }                 }); 

StaggeredGridLayoutManager doesn't provide me with this functionality like GridLayoutManager does.

Is there a different way of doing this? I have searched but not found anyone with the same problem, which is surprising as I would think this functionality would be quite useful for my scenario and for infinite scrolling, when a ProgressBar is shown in the last row of the RecyclerView.

Answer 1

You can use the setFullSpan method.
In this way the item will layout using all span area.

That means, if orientation is vertical, the view will have full width; if orientation is horizontal, the view will have full height.

Something like this:

public final void onBindViewHolder(RecyclerView.ViewHolder viewHolder, int position) {      StaggeredGridLayoutManager.LayoutParams layoutParams = (StaggeredGridLayoutManager.LayoutParams) viewHolder.itemView.getLayoutParams();     layoutParams.setFullSpan(true); } 

Pay attention.
It supports views that span all the columns, but it should be enough for your case.
