I'm trying to sort the values in my recyclerview by using a spinner. Can anyone help me with sorting this out? I'm specifically trying to organize the food by appetizer and treats, mains, and horse d'eourves. I would love to separate the item once one of the items on the spinner is selected. Your help will be greatly appreciated :)

Here is my code for the spinner:

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
       switch (position) {
           case 1:
           case 2:
           case 3:
               break;
 
                    }
    }

I am using SearchView filter in RecyclerView ,I Hope this Code Will Help You

searchview:

 searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    return false;
                }

                @Override
                public boolean onQueryTextChange(String newText) {
                    // inside on query text change method we are
                    // calling a method to filter our recycler view.
                    filter(newText);
                    return false;
                }
            });

Filter method
private EmployeeReportAdapter adapter;
private List<EmployeeDetails_Response> courseModalArrayList;
EmployeeDetails_Response is my model class :

 private void filter(String text) {
        try {
            // creating a new array list to filter our data.
            ArrayList<EmployeeDetails_Response> filteredlist = new ArrayList<>();

            // running a for loop to compare elements.
            for (EmployeeDetails_Response item : courseModalArrayList) {
                // checking if the entered string matched with any item of our recycler view.
                if (item.getEmployeeCode().toLowerCase().contains(text.toLowerCase())) {
                    // if the item is matched we are
                    // adding it to our filtered list.
                    filteredlist.add(item);
                }
            }
            if (filteredlist.isEmpty()) {
                // if no item is added in filtered list we are
                // displaying a toast message as no data found.
                Toast.makeText(this, "No Data Found..", Toast.LENGTH_SHORT).show();
            } else {
                // at last we are passing that filtered
                // list to our adapter class.
                adapter.filterList(filteredlist);
            }
        }catch (Exception e){

        }
    }

in adapter:

 public void filterList(ArrayList<EmployeeDetails_Response> filterllist) {
        try {
        // below line is to add our filtered
        // list in our course array list.
        employeeDetailsRespons = filterllist;
        // below line is to notify our adapter
        // as change in recycler view data.
        notifyDataSetChanged();
    }catch (Exception e){

    }
    }

Sort the ArrayList and it'll appear sorted in the RecyclerView

employeeDetailsRespons = filterllist.sort();
