Restar Loader can't update gridview - sql

Question

I've got two SQL tables inner join with content provider query builder. My loader shows the first in a gridview like a charm. The second table has been created to show a favorite list and so it has primary key, foreign key and another column. By the way when I try to retrieve value from this one I get null. Some suggestions, please!
I have this in content provider:
static {
sMovieByFavoriteQueryBuilder = new SQLiteQueryBuilder();
sMovieByFavoriteQueryBuilder.setTables(
MoviesContract.FavoriteEntry.TABLE_NAME + " INNER JOIN " +
MoviesContract.MovieEntry.TABLE_NAME +
" ON " + MoviesContract.FavoriteEntry.TABLE_NAME +
"." + MoviesContract.FavoriteEntry.COLUMN_FAVORITE_KEY +
" = " + MoviesContract.MovieEntry.TABLE_NAME +
"." + MoviesContract.MovieEntry._ID);
}
private static final String sFavoriteSelection =
MoviesContract.FavoriteEntry.TABLE_NAME +
"." + MoviesContract.FavoriteEntry.COLUMN_MOVIE_ID + " = ? AND " +
MoviesContract.FavoriteEntry.COLUMN_MOVIE_POSTER + " = ? AND " +
MoviesContract.MovieEntry.COLUMN_RELEASE_DATE + " = ? AND " +
MoviesContract.MovieEntry.COLUMN_MOVIE_POSTER + " = ? AND " +
MoviesContract.MovieEntry.COLUMN_ORIGINAL_TITLE + " = ? AND " +
MoviesContract.MovieEntry.COLUMN_SYNOSIS + " = ? AND " +
MoviesContract.MovieEntry.COLUMN_USER_RATING + " = ? ";
I call this method by uri from fragment:
#Override
public void onActivityCreated(Bundle savedInstanceState) {
getLoaderManager().initLoader(MOVIES_LOADER, null, this);
getLoaderManager().initLoader(FAVORITE_LOADER, null, this);
super.onActivityCreated(savedInstanceState);
}
void onSortChanged() {
System.out.println("onSortChanged: true");
updateMovies();
getLoaderManager().restartLoader(MOVIES_LOADER, null, this);
System.out.println("LoaderManager: " + getLoaderManager().restartLoader(MOVIES_LOADER, null, this));
}
void onFavorite() {
getLoaderManager().restartLoader(FAVORITE_LOADER, null, this);
mMoviesAdapter.setSelectedIndex(mPosition);
mMoviesAdapter.notifyDataSetChanged();
}
private void updateMovies() {
PopularMoviesSyncAdapter.syncImmediately(getActivity());
}
#Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
if (MainActivity.mFavorite == true) {
String sortOrder = MoviesContract.FavoriteEntry.COLUMN_FAVORITE_KEY;
String sortSetting = Utility.getPreferredSort(getActivity());
Uri movieFavoriteUri = MoviesContract.MovieEntry.buildMovieWithSortDate(sortSetting, System.currentTimeMillis());
System.out.println("movieFavoriteUri: " + movieFavoriteUri);
cursorFav = new CursorLoader(getActivity(),
movieFavoriteUri,
FAVORITE_COLUMNS,
null,
null,
sortOrder);
return cursorFav;
} else {
String sortOrder = MoviesContract.MovieEntry.COLUMN_DATE;
String sortSetting = Utility.getPreferredSort(getActivity());
System.out.println("sortSetting: " + sortSetting);
Uri movieForSortUri = MoviesContract.MovieEntry.buildMovieSort(sortSetting);
System.out.println("movieForSortUri: " + movieForSortUri);
cursorMov = new CursorLoader(getActivity(),
movieForSortUri,
MOVIES_COLUMNS,
null,
null,
sortOrder);
return cursorMov;
}
}
#Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
mMoviesAdapter.swapCursor(data);
if (mPosition != GridView.INVALID_POSITION) {
// If we don't need to restart the loader, and there's a desired position to restore
// to, do so now.
mGridView.smoothScrollToPosition(mPosition);
}
}
#Override
public void onLoaderReset(Loader<Cursor> loader) {
mMoviesAdapter.swapCursor(null);
}

Answer 1

Instead of:
sMovieByFavoriteQueryBuilder.setTables(
MoviesContract.FavoriteEntry.TABLE_NAME + " INNER JOIN " +
MoviesContract.MovieEntry.TABLE_NAME +
" ON " + MoviesContract.FavoriteEntry.TABLE_NAME +
"." + MoviesContract.FavoriteEntry.COLUMN_FAVORITE_KEY +
" = " + MoviesContract.MovieEntry.TABLE_NAME +
"." + MoviesContract.MovieEntry._ID);
Create a string so you can debug it easy.
strTables = MoviesContract.FavoriteEntry.TABLE_NAME + " INNER JOIN " +
MoviesContract.MovieEntry.TABLE_NAME +
" ON " + MoviesContract.FavoriteEntry.TABLE_NAME +
"." + MoviesContract.FavoriteEntry.COLUMN_FAVORITE_KEY +
" = " + MoviesContract.MovieEntry.TABLE_NAME +
"." + MoviesContract.MovieEntry._ID);
sMovieByFavoriteQueryBuilder.setTables(strTables);
Then try to run that join direct on db. My guess is the query have some issues.

I checked and the query works good. But my method can't return anything
private Cursor getMovieByFavorite(Uri uri, String[] projection, String movieId) {
String sortSetting = MoviesContract.MovieEntry.getFavoriteFromUri(uri);
long date = MoviesContract.MovieEntry.getDateFromUri(uri);
String[] selectionArgs;
String selection;
selection = sFavoriteSelection;
selectionArgs = new String[]{sortSetting};
return sMovieByFavoriteQueryBuilder.query(mOpenHelper.getReadableDatabase(),
projection,
selection,
null,
null,
null,
movieId
);
}
