Android RecyclerView: Change layout file LIST to GRID onOptionItemSelected

Question

I am developing an Android Application for Online Shopping. I have created following view for List of Products using RecyclerView, in that i want to change view

Answer 1

I found solution with the starting of activity I have set LinearLayoutManager like:

mLayoutManager = new LinearLayoutManager(this);
mProductListRecyclerView.setLayoutManager(mLayoutManager);

after that onOptionsItemSelected written like:

case R.id.menu_product_change_view:
     isViewWithCatalog = !isViewWithCatalog;
     supportInvalidateOptionsMenu();
     //loading = false;
     mProductListRecyclerView.setLayoutManager(isViewWithCatalog ? new LinearLayoutManager(this) : new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL));
     mProductListRecyclerView.setAdapter(mAdapter);
     break;

and changing view in onCreateViewHolder like:

@Override
public ProductRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View v = LayoutInflater.from(viewGroup.getContext()).inflate(isViewWithCatalog ? R.layout.product_row_layout_list : R.layout.product_row_layout_grid, null);
    ProductRowHolder mh = new ProductRowHolder(v);
    return mh;
}

From Starting to Ending you have to manage isViewWithCatalog variable for displaying which layout first.
