java - How to set repeated notification for specific day of week? -

i looking set notification on week days. have added string of days in alert dialog show days.

i want set day in calendar user has selected in alert dialog. also, should repeat next week on same day.

i have put time picker dialog choose time of notification. if c.gettime() , current date , time.

how set notification other days? if today monday , want create notification on wed? how can set wed in calendar?

  c.set(calendar.hour_of_day, hour);         c.set(calendar.minute, minute);         c.set(calendar.second,0);         c.set(calendar.millisecond,0);          notification = c.gettime();         notificationtime = df.format(notification);         notifytime.settext(notificationtime);         toast.maketext(getapplicationcontext(),string.valueof(notification),toast.length_short).show(); 

for notification using alarm manager.

 private void setalarm(calendar targetmcalen) {      intent intent = new intent(getbasecontext(),notificationreceiver.class);     pendingintent pendingintent = pendingintent.getbroadcast(getbasecontext(), rqs_1, intent, 0);     alarmmanager alarmmanager = (alarmmanager)getsystemservice(context.alarm_service);     alarmmanager.setinexactrepeating(alarmmanager.rtc_wakeup,targetmcalen.gettimeinmillis(),             alarmmanager.interval_day *7, pendingintent);      componentname receiver = new componentname(getapplicationcontext(),notificationreceiver.class);     packagemanager pm = getapplicationcontext().getpackagemanager();      pm.setcomponentenabledsetting(receiver,             packagemanager.component_enabled_state_enabled,             packagemanager.dont_kill_app);      toast.maketext(getapplicationcontext(),"notification set",toast.length_short).show(); } 

alert dialog selecting day:

  selectday.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             final alertdialog.builder builder = new alertdialog.builder(addeventactivity.this);              builder.setsinglechoiceitems(r.array.day_array, -1,                     new dialoginterface.onclicklistener() {                         public void onclick(dialoginterface dialog, int item) {                              string[] day = getbasecontext().getresources().getstringarray(r.array.day_array);                              selectday.settext(day[item]);                              dialog.dismiss();                         }                     });             builder.show();         }     }); 

do have set dayofweek in calendar instance inside alert dialog? like

c.set(calendar.day_of_week)?

edit :

i tried way. dose may going 1 day ahead every time if choose day multiple times.

 selectday.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             final alertdialog.builder builder = new alertdialog.builder(addeventactivity.this);              builder.setsinglechoiceitems(r.array.day_array, -1,                     new dialoginterface.onclicklistener() {                         public void onclick(dialoginterface dialog, int item) {                              string[] day = getbasecontext().getresources().getstringarray(r.array.day_array);                              selectday.settext(day[item]);                              dayofweek = day[item];                              switch (dayofweek)                             {                                 case  "mon":                                     c.set(calendar.day_of_week,2);                                     c.gettime();                                     toast.maketext(getapplicationcontext(),string.valueof(c.gettime()),toast.length_short).show();                                     break;                                 case "tue":                                      c.set(calendar.day_of_week, 3);                                     c.gettime();                                     toast.maketext(getapplicationcontext(),string.valueof(c.gettime()),toast.length_short).show();                                     break;                                 case "wed":                                     c.set(calendar.day_of_week, 4);                                     c.gettime();                                     toast.maketext(getapplicationcontext(),string.valueof(c.gettime()),toast.length_short).show();                                     break;                                  case "thu":                                     c.set(calendar.day_of_week, 5);                                     c.gettime();                                     toast.maketext(getapplicationcontext(),string.valueof(c.gettime()),toast.length_short).show();                                     break;                                  case "fri":                                     c.set(calendar.day_of_week, 6);                                     c.gettime();                                     toast.maketext(getapplicationcontext(),string.valueof(c.gettime()),toast.length_short).show();                                     break;                                  case "sat":                                     c.set(calendar.day_of_week, 7);                                     c.gettime();                                     toast.maketext(getapplicationcontext(),string.valueof(c.gettime()),toast.length_short).show();                                     break;                                  case "sun":                                      c.set(calendar.day_of_week,1);                                     c.gettime();                                     toast.maketext(getapplicationcontext(),string.valueof(c.gettime()),toast.length_short).show();                             }                              dialog.dismiss();                         }                     });             builder.show();         }     }); 

please help..
