java - How to send bulk SMS with ProgressDialog in Android Studio? -

-

here problems :

  • i know how send sms, i'm using in loop like this, , know it's not send sms, i'd add delay (i.e. 1000 milliseconds). how ?

  • i'd use progressdialog show progress of sending sms. know i've use thread or asynctask this. don't find working code...

for moment, i've code, doesn't work :

button sendbutton = (button) findviewbyid(r.id.sendbutton); sendbutton.setonclicklistener(new button.onclicklistener() {     @override     public void onclick(view v) {         if (!studentlist.isempty()) {             (int = 0; < studentlist.size(); i++) {                 student currentstudent = studentlist.get(i);                 currentstudent.sendsms();             }         } else {             toast.maketext(getapplicationcontext(), "the list empty.", toast.length_short).show();         }     } });

if need more information, not hesitate.
