            num.setonclicklistener(new onclicklistener() {                      @override                     public void onclick(view v) {                          if (player.isplaying()) {                              player.stop();                          }                          player.release();                         player = new mediaplayer();                          textview tv = (textview)v;                         assetmanager manager = parent.getassets();                         try {                             fileinputstream mp3stream =                                  manager.openfd(tv.gettext() + ".mp3").createinputstream();                             player.setdatasource(                                 mp3stream.getfd());                              player.prepare();                             player.start();                         } catch (ioexception e) {                             // todo auto-generated catch block                             e.printstacktrace();                         }                         matrixselected(tv);                     }                 });
