audio - Playing just one sound android -

-

i'm developing little quizz app , play sound depending on if user answers question correctly or not.

i've got many sound files in "assets/".

what play 1 of these sounds. i've been able play sound, not one, both sound (correct , incorrect) played 1 after other.

how can play one? here's source:

public void audioplayer(){     //set mediaplayer         mp = new mediaplayer();      try {         string mp3file = "correct.mp3";         assetmanager assetman = getassets();         fileinputstream mp3stream = assetman.openfd(mp3file).createinputstream();          mp.setdatasource(mp3stream.getfd());         mp.prepare();         mp.start();     } catch (exception e) {         e.printstacktrace();     } }

put sound files i.e fail , applause in raw folder , use following code :

private assetfiledescriptor splaysounddescriptor = null; private assetfiledescriptor sfailsounddescriptor = null; private mediaplayer mp = null; public static final int fail_sound = 1; public static final int applause_sound = 2;  public void audioplayer(int soundtype){     //set mediaplayer         mp = new mediaplayer();     assetfiledescriptor soundfiledescriptor = null;     try {         if (sfailsounddescriptor == null) {             sfailsounddescriptor = context.getresources().                     openrawresourcefd(r.raw.fail);         }         if (sapplausesounddescriptor == null) {             sapplausesounddescriptor = context.getresources().                     openrawresourcefd(r.raw.applause);         }         switch (soundtype) {             case fail_sound:                 soundfiledescriptor = sfailsounddescriptor;                 break;             case applause_sound:                 soundfiledescriptor = sapplausesounddescriptor;                 break;         }         mp.reset();         mp.setdatasource(soundfiledescriptor.getfiledescriptor(),                         soundfiledescriptor.getstartoffset(),                         soundfiledescriptor.getdeclaredlength());         mp.prepare();         mp.setonpreparedlistener(new onpreparedlistener() {              @override             public void onprepared(mediaplayer player) {                 player.seekto(0);                 player.start();             }         });       } catch (exception e) {         e.printstacktrace();     } }

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey?
