Как мне написать код "получить по индексу", полученный из комнаты БД, поставщику контента? Вот мой код (FavoriteContentProvider. java)

Question

Это мой поставщик содержимого (FavoriteContentProvider. java)

Как мне поставить условие «получить по индексу» в поставщик содержимого => эту строку оператора (if (code == CODE_DIR || code = = CODE_ITEM) {final Context context = getContext ();) из источников Favorite Entity и Favorite Dao?

private static final int CODE_DIR = 1;
private static final int CODE_ITEM = 2;

private static final UriMatcher MATCHER = new UriMatcher(UriMatcher.NO_MATCH);

static {
    MATCHER.addURI(AUTHORITY, FavoriteEntity.TABLE_NAME, CODE_DIR);
    MATCHER.addURI(AUTHORITY, FavoriteEntity.TABLE_NAME + "/*", CODE_ITEM);
}

@Override
public boolean onCreate() {
    FavoriteRoomDatabase mFavoriteRoomDatabase = FavoriteRoomDatabase.getDatabase(getContext());
    return true;
}

@Override
public Cursor query(@NonNull Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) {
    final int code = MATCHER.match(uri);
    if (code == CODE_DIR || code == CODE_ITEM){
        final Context context = getContext();

        if (context == null) {
            return null;
        }

        FavoriteDao mFavoriteDao = FavoriteRoomDatabase.getDatabase(context).favoriteDao();
        Cursor cursor = null;

        if (code == CODE_DIR) {
            cursor = mFavoriteDao.selectAll();
        }
        Objects.requireNonNull(cursor).setNotificationUri(context.getContentResolver(), uri);
        return cursor;

    }else {
        throw new IllegalArgumentException("Unknown URI: " + uri);
    }
}

@Nullable
@Override
public String getType(@NonNull Uri uri) {
    return null;
}

@Override
public Uri insert(@NonNull Uri uri, ContentValues values) {
    throw new UnsupportedOperationException("Not yet implemented");
}

@Override
public int delete(@NonNull Uri uri, String selection, String[] selectionArgs) {
    throw new UnsupportedOperationException("Not yet implemented");
}

@Override
public int update(@NonNull Uri uri, @Nullable ContentValues values, @Nullable String selection, @Nullable String[] selectionArgs) {
    return 0;
}

И это моя любимая комната Dao

@Query("SELECT * from "+ FavoriteEntity.TABLE_NAME +" ORDER BY "+ FavoriteEntity.COLUMN_ID +" ASC")
LiveData<List<FavoriteEntity>> getAllFavorite();

@Query("SELECT COUNT(*) FROM "+ FavoriteEntity.TABLE_NAME +" WHERE "+ FavoriteEntity.COLUMN_USER_ID +" == :userId")
LiveData<Integer> getCount(int userId);

@Query("SELECT * FROM " + FavoriteEntity.TABLE_NAME)
Cursor selectAll();

@Insert(onConflict = OnConflictStrategy.IGNORE)
void insert(FavoriteEntity mFavoriteEntity);

@Delete()
void delete(FavoriteEntity mFavoriteEntity);

@Query("Delete FROM "+ FavoriteEntity.TABLE_NAME +" where "+ FavoriteEntity.COLUMN_LOGIN +" LIKE  :login")
void deleteUserByLogin(String login);

и FavoriteEntity
