android - Searching in a ListFragment using LoaderEX -

i'm having major block trying search data in lists generated using cursors prepopulated sqlite db.

i'm using following libs:

• actionbarsherlock.
• sqlite asset helper (to ease loading of data db).
• loaderex.

when start app, list empty , when type letters on searchview, nothing displayed. query used works because before trying implement library data displayed.

what doing wrong? thank in advance.

thanks commonsware, figured out putting initloader() method inside onactivitycreated wrong because called once.

instead, should put restartloader() method inside funcion called everytime searchview gets updated, onquerytextchange.

final private onquerytextlistener querylistener = new onquerytextlistener() {      @override     public boolean onquerytextchange(string newtext) {         if (textutils.isempty(newtext)) {             currentquery = "";             toast.maketext(getactivity(), "searching for: " + currentquery + "...", toast.length_short).show();         } else {             currentquery = newtext;             toast.maketext(getactivity(), "searching for: " + currentquery + "...", toast.length_short).show();         }         **getloadermanager().restartloader(mvp_id, null, fragmvp.this);**         return false;     }      @override     public boolean onquerytextsubmit(string query) {         currentquery = query;         return false;     } };
