Staggered grid layout manager dynamic number of columns

Question

How i can make dynamic number of columns in RecyclerView using StaggeredGridLayoutManager. I already have working RecyclerView. Here is screen what i need to do:

Answer 1

if max columns are two that would be quite simple.For the view that occupy the full width,setFullSpan(true) like in your BindView method of Recyclerview Adapter

//rlm is RecyclerView.LayoutManager passed in constructor or setter in adapter 
if (rlm instanceof StaggeredGridLayoutManager) {
   StaggeredGridLayoutManager.LayoutParams layoutParams = (StaggeredGridLayoutManager.LayoutParams) holder.itemView.getLayoutParams();
    /*
     * to make View to occupy full width of the parent
     */
     layoutParams.setFullSpan(true);
}
