会议室数据库获取价值图

Question

我需要得到类似的东西： Map<String, Boolean>或List<Pair>

Dao:

...
@Query("SELECT id, isFavorite FROM sources")
fun getCompareData(): Map<String, Boolean>
...

Entitiy:

@Entity(tableName = "sources")
data class Source(
    @PrimaryKey val id: String,
    val name: String,
    val description: String,
    val language: String,
    val country: String,
    var isFavorite: Boolean = false
)

或者我该怎么做？

更新：我刚刚创建

data class Favorite(
val id: String,
val isFavorite: Boolean
)

并写成`fun getFavorites（）：列表
