Android Studio – RecyclerView wont change orientation

I am trying to allign my cardViews horizontally inside my recyclerView, but when i change the orientation attribute in the XML nothing changes. Does anyone know which other factors are involved? Could there be a problem in the adapter or the card_layout file?

    When you create your layoutManager Class, use LinearLayoutManager.HORIZONTAL

    val layoutManager
    = LinearLayoutManager(requireContext(), LinearLayoutManager.HORIZONTAL, false)

binding.recyclerview.setLayoutManager(layoutManager)

    If you want recyclerview allign VERTICAL

    recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));

    And for HORIZONTAL

    recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));

    just add this line in your code…
