android - wait a little before finish my activity -


what's best way wait before activity finished?

in fact launch new activity named masternumber mainactivity "startactivityforresult". masternumber send sms , shows toast "sms sent", masternumber activity closed toast showed in mainactivity.

here content of mainactivity:

//lorsqu'on clique sur le bouton "send" button button1 = (button) findviewbyid(r.id.masterbutton1); button1.setonclicklistener(new view.onclicklistener() {     @override     public void onclick(view v) {         try {             smsmanager smsmanager = smsmanager.getdefault();             smsmanager.sendtextmessage(automatikrn, null, "#00#", null, null);             toast.maketext(getapplicationcontext(), "sms sent!",             toast.length_long).show();         }         catch (exception e) {             toast.maketext(getapplicationcontext(),                 "sms failed, please try again later!",                 toast.length_long).show();                 e.printstacktrace();         }         finish();     } });

and here content of masternumber (activity)

//lorsqu'on clique sur le bouton add master number button button2 = (button) findviewbyid(r.id.mainbutton2); button2.setonclicklistener(new view.onclicklistener() {      @override     public void onclick(view v) {         //on va appeler l'activité masternumber (#recipientnumberautomatik-1)         intent setmasternumber = new intent(mainactivity.this, masternumber.class);         setmasternumber.putextra("mn", recipientnumber);    //on lui fournit le n° du dest. afin qu'il soit saisit automatiquement         startactivityforresult(setmasternumber, 1);     } });

try : 

//lorsqu'on clique sur le bouton "send"         button button1 = (button) findviewbyid(r.id.masterbutton1);         button1.setonclicklistener(new view.onclicklistener()         {             @override             public void onclick(view v)             {                 try                 {                     smsmanager smsmanager = smsmanager.getdefault();                     smsmanager.sendtextmessage(automatikrn, null, "#00#", null, null);                     toast.maketext(getapplicationcontext(), "sms sent!",                                 toast.length_long).show();                 }                 catch (exception e)                 {                     toast.maketext(getapplicationcontext(),                         "sms failed, please try again later!",                         toast.length_long).show();                     e.printstacktrace();                 }                 new handler().postdelayed(new runnable() {          @override         public void run() {             finish();         }         }, toast.length_long);              }         });

by using postdelayed runnable, actions places inside run() method executed after toast.length_long time has passed.
