Examplary code showing how to change Fragment layout on orientation change in Android.

MyFragment.java

public class MyFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle bundle) {
        View view = inflater.inflate(R.layout.my_fragment, container, false);
        
        // Find your buttons in view, set up onclicks, set up callbacks to your parent fragment or activity here.
        
        // You can create ViewHolder or separate method for that.
        // example of accessing views: TextView textViewExample = (TextView) view.findViewById(R.id.text_view_example);
        // textViewExample.setText("example");
        
        return view;
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        LayoutInflater inflater = LayoutInflater.from(getActivity());
        populateViewForOrientation(inflater, (ViewGroup) getView());
    }

    private void populateViewForOrientation(LayoutInflater inflater, ViewGroup viewGroup) {
        viewGroup.removeAllViewsInLayout();
        View subview = inflater.inflate(R.layout.my_fragment, viewGroup);

        // Find your buttons in subview, set up onclicks, set up callbacks to your parent fragment or activity here.
        
        // You can create ViewHolder or separate method for that.
        // example of accessing views: TextView textViewExample = (TextView) view.findViewById(R.id.text_view_example);
        // textViewExample.setText("example");
    }
