StaggeredGridLayoutManager change spanCount dynamically RecyclerView

Question

How can we change the spanCount of RecyclerView dynamically?

My code create 3 column of cards in RecyclerView:

 StaggeredGridLayoutManager mFavouratesLayoutManager;
 mFavouratesLayoutManager = new StaggeredGridLayoutManager(3,
                StaggeredGridLayoutManager.VERTICAL);

I'm trying to make the adapter like:

• one element at top row
• 2 elements in second row
• 3 items below that

Answer 1

StaggeredGridLayoutManager does not support that. You can change the span count but it will effect every row. Your only option is to have full rows w/ SGLM.

If you use GridLayoutManager, you can achieve that by setting span count to 6, then providing a SpanSizeLookup that returns

• 6 for first item
• 3 for items 1 and 2
• 2 for items 3 4 5

Etc.
