如何搜索RecyclerView中显示的对象列表？

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> implements Filterable {
    private List<MyObject> originalList; // 原始数据源
    private List<MyObject> filteredList; // 过滤后的数据源

    // 构造方法和ViewHolder等其他方法省略

    @Override
    public Filter getFilter() {
        return new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence constraint) {
                FilterResults results = new FilterResults();
                String keyword = constraint.toString().toLowerCase();

                if (keyword.isEmpty()) {
                    results.values = originalList;
                    results.count = originalList.size();
                } else {
                    List<MyObject> filteredObjects = new ArrayList<>();
                    for (MyObject object : originalList) {
                        // 根据搜索关键字过滤数据
                        if (object.getName().toLowerCase().contains(keyword)) {
                            filteredObjects.add(object);
                        }
                    }
                    results.values = filteredObjects;
                    results.count = filteredObjects.size();
                }

                return results;
            }

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

EditText searchEditText = findViewById(R.id.search_edit_text);
RecyclerView recyclerView = findViewById(R.id.recycler_view);
MyAdapter adapter = new MyAdapter(originalList);

recyclerView.setAdapter(adapter);

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) {
        adapter.getFilter().filter(s);
    }

    @Override
    public void afterTextChanged(Editable s) {
    }
});
