我从Json数据中将数据转储到SQLite中.现在我的问题是我有一个包含多个表的数据库我希望使用id来关联多个表.这些是我创建的3个表.

这是我们有产品清单的第一张表,

private static final String DATABASE_CREATE_PRODUCT =
            "CREATE TABLE if not exists " + "product_template" + " (" +
                    "_id" + " integer PRIMARY KEY autoincrement," +
                    "name" + "," +
                    "list_price" + "," +
                    "create_date" + "," +
                    "default_code" + "," +
                    "ean13" + "," +
                    "image_new" + "," +
                    "image_variant" +
                    ");";

这是我们有合作伙伴名单的第二张表,

    private static final String DATABASE_CREATE_PARTNER =
            "CREATE TABLE if not exists " + "res_partner" + " (" +
                    "_id" + " integer PRIMARY KEY …

这是我的代码，每行显示 2 个项目。

extends Fragment {

private RecyclerView recyclerView;
private AlbumsAdapter adapter;
private List<Album> albumList;
protected View view;
private FloatingActionButton fab;


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    view = inflater.inflate(R.layout.fragment_ebooks, container, false);
    fab = (FloatingActionButton) view.findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent(getActivity(), ProductsActivity.class);
            startActivity(intent);
        }
    });
    initCollapsingToolbar();

    recyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);

    albumList = new ArrayList<>();
    adapter = new AlbumsAdapter(getActivity(), albumList);

    RecyclerView.LayoutManager …
