RecyclerView wont change orientation-CodePudding

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?

CodePudding user response：

When you create your layoutManager Class, use LinearLayoutManager.HORIZONTAL

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

binding.recyclerview.setLayoutManager(layoutManager)

CodePudding user response：

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... Thank You...
