In the precise case that when you are in Portrait display a number of columns that complete the width of the screen and when in Landscape the items in recyclerview are presented in a number of columns proportional to the new width, preventing it to be deformed the proportions of cardviews.

Use the getRotation():

WindowManager manager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);

if (manager != null) {
    Display display = manager.getDefaultDisplay();
    int rotation = display.getRotation();

    if (rotation == Surface.ROTATION_90 || rotation == Surface.ROTATION_270) {
        //em LADNSCAPE atribuimos uma quantidade de colunas maior a sua recycler view
        recyclerView.setLayoutManager(new GridLayoutManager(this, 4));
    } else {
        //em PORTRAIT uma quantidade menor
        recyclerView.setLayoutManager(new GridLayoutManager(this, 2));
    }
}

You can run this code on your onCreate, when configuring your UI.

  • And in case I implement my recyclerview in a Fragment, I would use that code, or I would have another way in that case?

  • The only difference is that you would need to allocate this code to onCreateView of your Fragment. Works normally.

  • Thanks for the help! And sorry for the delay in thanking you. It worked right here.
