如何在recyclerViewAdapter中添加搜索功能

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> originalData;
    private List<String> filteredData;

    public MyAdapter(List<String> data) {
        originalData = data;
        filteredData = new ArrayList<>(data);
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        // 创建ViewHolder
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        // 绑定数据到ViewHolder
    }

    @Override
    public int getItemCount() {
        return filteredData.size();
    }

    @Override
    public Filter getFilter() {
        return new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence constraint) {
                String keyword = constraint.toString().toLowerCase();
                List<String> filteredList = new ArrayList<>();

                for (String item : originalData) {
                    if (item.toLowerCase().contains(keyword)) {
                        filteredList.add(item);
                    }
                }

                FilterResults results = new FilterResults();
                results.values = filteredList;
                results.count = filteredList.size();
                return results;
            }

            @Override
            protected void publishResults(CharSequence constraint, FilterResults results) {
                filteredData = (List<String>) results.values;
                notifyDataSetChanged();
            }
        };
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        // ViewHolder的实现
    }
}

EditText searchEditText = findViewById(R.id.search_edit_text);
searchEditText.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    }

    @Override
    public void afterTextChanged(Editable s) {
        adapter.getFilter().filter(s.toString());
    }
});
