如何在autocompletetextview中获取sqlite数据？

public class MyAdapter extends BaseAdapter implements Filterable {
    private List<String> mData; // 存储从数据库中获取的数据
    private Context mContext;

    public MyAdapter(Context context) {
        mContext = context;
        mData = new ArrayList<>();
    }

    @Override
    public int getCount() {
        return mData.size();
    }

    @Override
    public Object getItem(int position) {
        return mData.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null) {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.item_layout, parent, false);
            holder = new ViewHolder();
            holder.textView = convertView.findViewById(R.id.text_view);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        holder.textView.setText(mData.get(position));

        return convertView;
    }

    @Override
    public Filter getFilter() {
        Filter filter = new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence constraint) {
                FilterResults results = new FilterResults();
                List<String> filteredData = new ArrayList<>();

                // 从数据库中查询与用户输入匹配的数据
                SQLiteDatabase db = SQLiteDatabase.openDatabase("your_database_path", null, SQLiteDatabase.OPEN_READONLY);
                Cursor cursor = db.rawQuery("SELECT * FROM your_table WHERE column_name LIKE ?", new String[]{constraint + "%"});
                if (cursor != null && cursor.moveToFirst()) {
                    do {
                        String data = cursor.getString(cursor.getColumnIndex("column_name"));
                        filteredData.add(data);
                    } while (cursor.moveToNext());
                    cursor.close();
                }

                results.values = filteredData;
                results.count = filteredData.size();
                return results;
            }

            @Override
            protected void publishResults(CharSequence constraint, FilterResults results) {
                if (results != null && results.count > 0) {
                    mData = (List<String>) results.values;
                    notifyDataSetChanged();
                } else {
                    notifyDataSetInvalidated();
                }
            }
        };

        return filter;
    }

    private static class ViewHolder {
        TextView textView;
    }
}

AutocompleteTextView autoCompleteTextView = findViewById(R.id.autocomplete_text_view);
MyAdapter adapter = new MyAdapter(this);
autoCompleteTextView.setAdapter(adapter);
