Hello I Have a problem with my Indexer. So basically its a ListView That displays songs and an Alphabet Indexer that shows the first letter of the song title.Now the problem is that "sometimes" the app crashes and the log says that the indexer tried to access a cursor after it closed. So Any Help Would Be Great.
SongFragment :
public class SongFragment extends Fragment implementsLoaderManager.LoaderCallbacks<Cursor>,OnItemClickListener{
String Song;
Cursor cursor;
public static ListView songList;
TextView songNumb;
EditText search;
private AlphabetIndexer mAlphaIndexer;
SongAdapter mAdapter;
private String mPlaylist;
public static String value;
int music_column_index;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View myFragmentView = inflater.inflate(R.layout.fragment_song, container, false);
songList = (ListView) myFragmentView.findViewById(R.id.songlist);
songNumb = (TextView) myFragmentView.findViewById(R.id.songnumb);
return myFragmentView;
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
boolean mEditMode = false;
//Log.i("@@@", "starting query");
mAdapter = new SongAdapter(
getActivity(), // need to use application context to avoid leaks
this,
mEditMode ? R.layout.rowlayout : R.layout.rowlayout,
null, // cursor
new String[] {},
new int[] {},
"nowplaying".equals(mPlaylist),
mPlaylist != null &&
!(mPlaylist.equals("podcasts") || mPlaylist.equals("recentlyadded")));
songList.setAdapter(mAdapter);
songList.setFastScrollEnabled(true);
songList.setScrollingCacheEnabled(true);
getLoaderManager().initLoader(0, null, this);
songList.setOnItemClickListener(this);
}
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
String select = null;
final StringBuilder mSelection = new StringBuilder();
mSelection.append(AudioColumns.IS_MUSIC + "=1");
mSelection.append(" AND " + AudioColumns.TITLE + " != ''");
return new CursorLoader(getActivity(), MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
new String[] {
/* 0 */
BaseColumns._ID,
/* 1 */
AudioColumns.TITLE,
/* 2 */

AudioColumns.ALBUM,
/* 4 */
AudioColumns.DURATION,

}, mSelection.toString(), null,
AudioColumns.TITLE);
}
@Override
