java - Cursor Adapter selecting the wrong items to delete? -


so know question has been posted few times on site, case si little different.

suppose have these items in cursor (in order) :

alaska canada united states of america mongolia china india

when click alaska, log shows mongolia clicked, , right after that, if select canada, shows mongolia clicked

and after click mongolia, united states of america clicked instead

it having weird behavior above. here code cursor adapter:

public class eventlistcursoradapter extends cursoradapter {     private layoutinflater cursorinflater;     calculations calculations = new calculations();     gson gson = new gson();     context appcontext;     databasehelper dbhelper;     context mcontext;     string[] whereclause;     intent mainactivityintent;      public eventlistcursoradapter(context context, cursor c, int flags) {         super(context, c, flags);         cursorinflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service);         appcontext = context.getapplicationcontext();         mcontext = context;         notifydatasetchanged();     }     @override     public view newview(context context, cursor cursor, viewgroup parent) {         return cursorinflater.inflate(r.layout.card_view, parent, false);     }     @override     public void bindview(view view, context context, cursor cursor) {         textview timetext = (textview) view.findviewbyid(r.id.event_time);

how choose right item delete cursor adapter? appreciated...

a cursor result set database position pointer current row. scroll list , new rows filled in based on cursor data, position pointer automatically moved under covers.so save cursor position in bindview method.

change onclicklistener in bindview blow 

@override     public void bindview(view view, context context, cursor cursor) {      final int position = cursor.getposition();       deletebutton.setonclicklistener(new view.onclicklistener() {                         @override                         public void onclick(view view) {                           cursor.movetoposition(position);                             //now delete operation                          }                     });  }

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
