I have been try to implemented the Paging Library with Room provided by google in Android Architecture Component.But its showing compile time error in my UserDao
Class
Here is the Error:
Error:(22, 42) error: Not sure how to convert a Cursor to this method's return type
My Question is what return Type ?
UserDao.java
@Dao
public interface UserDao {
@Query("SELECT * FROM user")
LiveData<List<User>> getAll();
//Compile Error is here : Not sure how to convert a Cursor to this method's return type
@Query("SELECT * FROM user")
LivePagedListProvider<Integer, User> userByPagination();
}
Here the UserModel.java
public class UserModel extends AndroidViewModel {
private final UserDao userDao;
public UserModel(Application application) {
super(application);
userDao = RoomDB.getDefaultInstance().userDao();
}
public LiveData<List<User>> getAllUser() {
return userDao.getAll();
}
public LiveData<PagedList<User>> getAllUserPagination() {
return userDao.userByPagination().create(
/* initial load position */ 0,
new PagedList.Config.Builder()
.setEnablePlaceholders(true)
.setPageSize(10)
.setPrefetchDistance(5)
.build());
}
}
I have refer the following sample:
