android - How to implement the call back mechanism between Activites -


i have 2 activities first details activity , second activity page confirmationpage,once confirm should come first page,how should handle scenario?

is possible between activities,instead of using fragments?

you have use startactivityforresult(); method when start secondactivity.

and have implement onactivityresult() method.

here code first activity..

@override protected void onactivityresult(int requestcode, int resultcode, intent data) {     // todo auto-generated method stub     super.onactivityresult(requestcode, resultcode, data);      if (resultcode == 1) {         bundle = data.getextras();         string id = extra.getstring("namekey").trim();          // code here.      } }

code in second activity..

add code on confirm click button.

    intent = new intent();     bundle = new bundle();     extra.putstring("namekey", keyvalue);      i.putextras(extra);     setresult(1, i);     finish();
