添加新房间2.2.2依赖项后无法构建Androidx项目

我一段时间以来一直在使用Room，已经使用Realm多年了，我不禁注意到Room's的{​​{1}}实现有点关。当发生这种情况时，我的UpdateOrInsert ID（即所谓的“已更新”字段）的ID丢失了，这表示我在互联网上散步并完全删除了旧记录，而不是更新了旧记录。发现自己实现了solution。我是一个autoGenerate人，所以我不得不将其转换为Java，结果是

Java

然后我制作了模型

@SchedulerSupport(value = SchedulerSupport.IO)
@Dao
public abstract class BaseDao<T> {

    @Insert(onConflict = OnConflictStrategy.IGNORE)
    abstract Long insert(T item);

    @Insert(onConflict = OnConflictStrategy.IGNORE)
    abstract List<Long> insert(List<T> items);

    @Update
    abstract void update(T item);

    @Update
    abstract void update(List<T> items);

    @Transaction
    public void insertOrUpdate(T item) {
        Long id = insert(item);
        if (id == -1L)
            update(item);
    }

    @Transaction
    public void insertOrUpdate(List<T> objList) {
        List<Long> insertResult = this.insert(objList);
        List<T> updateList = new ArrayList<>();

        for(int i = 0; i < insertResult.size(); i++)
            if (insertResult.get(i) == -1L)
                updateList.add(objList.get(i));

        if (!updateList.isEmpty())
            this.update(updateList);
    }

}

最后，我将两个链接起来

@Builder
@Entity
@TypeConverters({Address.Type.class})
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@EqualsAndHashCode
@ToString
public class Address {
@PrimaryKey(autoGenerate = true)
    private int uuid;
    @Ignore
    private String placeUuid;
    @ColumnInfo(name = "type")
    private Type type;
    @ColumnInfo(name = "title")
    private String title;
    @ColumnInfo(name = "icon")
    private int icon;
    @ColumnInfo(name = "address")
    private String address;
    @ColumnInfo(name = "is_address_available")
    private boolean isAddressAvailable;
    @ColumnInfo(name = "lat")
    private double lat;
    @ColumnInfo(name = "lng")
    private double lng;
}

在我尝试使用@Dao public abstract class AddressDaoImpl extends BaseDao<Address>{ } 依赖项进行编译之前，一切都很好

pre-AndroidX versions of Room

编译器抱怨在谷歌搜索后我需要实现implementation "android.arch.persistence.room:runtime:1.1.1" annotationProcessor "android.arch.persistence.room:compiler:1.1.1" implementation "android.arch.persistence.room:rxjava2:1.1.1" ，我终于找到了解决方案。我使用的是错误的abstract List<Long> insert(List<T> items)，除这些以外，我所有其他依赖项都是AndroidX，由于某种原因，事实证明它们的更新频率不及Room dependencies版本，因此我更新为新的{{ 1}}，它们看起来像

AndroidX

迁移到这些依赖项后，该错误消失了，但出现了一个新错误，现在我面临着这个错误，我什至不知道如何解决它

2.2.2

我的完整implementation 'androidx.room:room-runtime:2.2.2' annotationProcessor 'androidx.room:room-compiler:2.2.2' implementation 'androidx.room:room-rxjava2:2.2.2' 文件看起来像

如果您遇到类似的问题，请提供帮助。

1 个答案:

答案 0 :(得分：0)

事实证明Sonnet是正确的，我的代码中有一个错误，错误是它仍然抱怨我的abstract BaseDao中没有覆盖的抽象方法。在这一点上，我只剩下一个解决方案。制作interface的{​​{1}}版本，其中包含我的所有方法定义，并以BaseDao的形式实现我感兴趣的定义，例如

BaseDao which i renamed to BaseDaoImpl

界面

@SchedulerSupport(value = SchedulerSupport.IO)
@Dao
public abstract class BaseDaoImpl<T> implements BaseDao<T> {

    @Transaction
    public void insertOrUpdate(T item) {
        Long id = insert(item);
        if (id == -1L)
            update(item);
    }

    @Transaction
    public void insertOrUpdate(List<T> objList) {
        List<Long> insertResult = this.insert(objList);
        List<T> updateList = new ArrayList<>();

        for (int i = 0; i < insertResult.size(); i++)
            if (insertResult.get(i) == -1L)
                updateList.add(objList.get(i));

        if (!updateList.isEmpty())
            this.update(updateList);
    }

}

然后我像在地址道中一样使用它

@SchedulerSupport(value = SchedulerSupport.IO)
@Dao
public interface BaseDao<T> {

    @Insert(onConflict = OnConflictStrategy.IGNORE)
    Long insert(T item);

    @Insert(onConflict = OnConflictStrategy.IGNORE)
    List<Long> insert(List<T> items);

    @Update
    void update(T item);

    @Update
    void update(List<T> items);

}
