I have a requirement where I need to have horizontal scrolling and vertical scrolling in a recycler view. It is based on the type of data that is coming from server. If the
LayoutManager is the class that layout views in RecyclerView. So change recyclerView.setLayoutManager(LayoutManager) if you want to change layout. In your case, if you use LinearLayoutManager, do this by calling:
LinearLayoutManager layoutManager = ...
recyclerView.setLayoutManager(layoutManager);
//when you want horizontal
layoutManager.setOrientation(context, LinearLayoutManager.HORIZONTAL);
//when you want vertical
layoutManager.setOrientation(context, LinearLayoutManager.VERTICAL);
