添加新房间 2.2.2 依赖项后 Androidx 项目未构建
Androidx project not building after adding the new room 2.2.2 dependencies
我已经使用 Room 一段时间了，使用 Realm 多年后，我不禁注意到 UpdateOrInsert 的 Room's 实现是有点不对劲。它完全删除旧记录并添加新记录而不是更新旧记录，当发生这种情况时，我的所谓 "updated" 字段的 autoGenerate ID 丢失了，也就是说我在上网，发现自己正在实施这个 solution。我是一个 Java 人所以我不得不将它转换为 Java 结果是
@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);
}
}
然后我做了我的模型
@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;
}
最后我把两者联系起来
@Dao
public abstract class AddressDaoImpl extends BaseDao<Address>{
}
一切都很好，直到我尝试使用 pre-AndroidX versions of Room 依赖项
进行编译
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"
编译器抱怨我需要实现 abstract List<Long> insert(List<T> items) 经过 google 搜索后我终于找到了解决方案。我使用了错误的 Room dependencies，除了这些之外，我的所有其他依赖项都是 AndroidX，出于某种原因，事实证明它们没有像 AndroidX 版本那样经常更新，所以我更新到新的 2.2.2 他们看起来像
implementation 'androidx.room:room-runtime:2.2.2'
annotationProcessor 'androidx.room:room-compiler:2.2.2'
implementation 'androidx.room:room-rxjava2:2.2.2'
迁移到这些依赖项后，错误消失了，但出现了一个新错误，现在我正面临这个错误，我什至不知道如何修复它

如果您遇到过类似的问题，请帮忙。
事实证明 Sonnet 是对的，我的代码中有一个错误，错误是它仍然在抱怨在我的 abstract BaseDao 中没有被重写的抽象方法。在这一点上，我只剩下一个解决方案；制作我的 BaseDao 的 interface 版本，其中包含我所有的方法定义并实现我感兴趣的方法，在 BaseDao which i renamed to BaseDaoImpl 中，例如
@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);
}
}
界面
@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);
}
然后我在我的 Address Dao 中使用它就像
@Dao
public abstract class AddressDaoImpl extends BaseDaoImpl<Address> implements AddressDao {
}
我已经使用 Room 一段时间了，使用 Realm 多年后，我不禁注意到 UpdateOrInsert 的 Room's 实现是有点不对劲。它完全删除旧记录并添加新记录而不是更新旧记录，当发生这种情况时，我的所谓 "updated" 字段的 autoGenerate ID 丢失了，也就是说我在上网，发现自己正在实施这个 solution。我是一个 Java 人所以我不得不将它转换为 Java 结果是
@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);
}
}
然后我做了我的模型
@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;
}
最后我把两者联系起来
@Dao
public abstract class AddressDaoImpl extends BaseDao<Address>{
}
一切都很好，直到我尝试使用 pre-AndroidX versions of Room 依赖项
implementation "android.arch.persistence.room:runtime:1.1.1"
annotationProcessor "android.arch.persistence.room:compiler:1.1.1"

编译器抱怨我需要实现 abstract List<Long> insert(List<T> items) 经过 google 搜索后我终于找到了解决方案。我使用了错误的 Room dependencies，除了这些之外，我的所有其他依赖项都是 AndroidX，出于某种原因，事实证明它们没有像 AndroidX 版本那样经常更新，所以我更新到新的 2.2.2 他们看起来像
implementation 'androidx.room:room-runtime:2.2.2'
annotationProcessor 'androidx.room:room-compiler:2.2.2'
implementation 'androidx.room:room-rxjava2:2.2.2'
迁移到这些依赖项后，错误消失了，但出现了一个新错误，现在我正面临这个错误，我什至不知道如何修复它

如果您遇到过类似的问题，请帮忙。
事实证明 Sonnet 是对的，我的代码中有一个错误，错误是它仍然在抱怨在我的 abstract BaseDao 中没有被重写的抽象方法。在这一点上，我只剩下一个解决方案；制作我的 BaseDao 的 interface 版本，其中包含我所有的方法定义并实现我感兴趣的方法，在 BaseDao which i renamed to BaseDaoImpl 中，例如
@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);
}
}
界面
@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);
}
然后我在我的 Address Dao 中使用它就像
@Dao
public abstract class AddressDaoImpl extends BaseDaoImpl<Address> implements AddressDao {
}
