我需要处理Flowable<List<Object>>返回的ObjectDao。
DAO
@Dao
public interface DefectosDao
{
@Insert(onConflict = OnConflictStrategy.IGNORE)
void insertarDefectos(DefectoEntity defectos);
@Query("select * from defectos where cod_defecto = :cod")
Maybe<DefectoEntity> getByCod(String cod);
@Query("select * from defectos where pt = 1")
Maybe<List<DefectoEntity>> getPt();
@Query("select * from defectos where ct = 1")
Maybe<List<DefectoEntity>> getCt();
@Query("select * from defectos where apoyo = 1")
Flowable<List<DefectoEntity>> getApoyo();
}
处理程序
DataBase.getAppDatabase(Splash_Screen.this).Defecto().getApoyo()
.subscribeOn(Schedulers.newThread())
.observeOn(Schedulers.io())
.subscribe(item2->{
System.out.println(item2);});

我尝试过使用Maybe对象和Single对象，但没错。
进口

我尝试使用 RxJava 版本 1.0.1 和 2.0.1 -相同的问题。
