我想将一些物品发送到第二个活动的回收器视图。如何使用Room执行此操作

dependencies {
    def room_version = "2.4.0"

    implementation "androidx.room:room-runtime:$room_version"
    annotationProcessor "androidx.room:room-compiler:$room_version"
}

@Entity(tableName = "items")
public class Item {
    @PrimaryKey(autoGenerate = true)
    public int id;

    public String name;
    public String description;
    // 其他属性...

    // 构造函数、getter和setter方法...
}

@Dao
public interface ItemDao {
    @Insert
    void insert(Item item);

    @Query("SELECT * FROM items")
    List<Item> getAllItems();
    // 其他查询、更新、删除等方法...
}

@Database(entities = {Item.class}, version = 1)
public abstract class AppDatabase extends RoomDatabase {
    public abstract ItemDao itemDao();

    private static AppDatabase instance;

    public static synchronized AppDatabase getInstance(Context context) {
        if (instance == null) {
            instance = Room.databaseBuilder(context.getApplicationContext(),
                    AppDatabase.class, "app_database")
                    .build();
        }
        return instance;
    }
}

Item item = new Item();
item.setName("物品名称");
item.setDescription("物品描述");
// 设置其他属性...

AppDatabase db = AppDatabase.getInstance(this);
ItemDao itemDao = db.itemDao();
itemDao.insert(item);

AppDatabase db = AppDatabase.getInstance(this);
ItemDao itemDao = db.itemDao();
List<Item> itemList = itemDao.getAllItems();
// 显示物品列表...
