public class accountsetup extends activity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.account_main); this.initviews(); } private void initviews(){ textview user1 = (textview)findviewbyid(r.id.user1); button iconnext1 = (button)findviewbyid(r.id.iconnext1); iconnext1.setonclicklistener(new onclicklistener() { public void onclick(view v) { intent intent1 = new intent(accountsetup.this, accountsettingactivity1.class); intent1.putextra("rowid","1"); startactivityforresult(intent1, 100); } }); button iconnext2 = (button)findviewbyid(r.id.iconnext2); iconnext2.setonclicklistener(new onclicklistener() { public void onclick(view v) { intent intent2 = new intent(accountsetup.this, accountsettingactivity2.class); startactivity(intent2); finish(); } }); button iconnext3 = (button)findviewbyid(r.id.iconnext3); iconnext3.setonclicklistener(new onclicklistener() { public void onclick(view v) { intent intent3 = new intent(accountsetup.this, accountsettingactivity3.class); //onnewintent((intent) v.gettag()); intent3.putextra("rowid","3"); startactivity(intent3); finish(); } }); button iconnext4 = (button)findviewbyid(r.id.iconnext4); iconnext4.setonclicklistener(new onclicklistener() { public void onclick(view v) { intent intent4 = new intent(accountsetup.this, accountsettingactivity4.class); //onnewintent((intent) v.gettag()); intent4.putextra("rowid","4"); startactivity(intent4); finish(); } }); button iconnext5 = (button)findviewbyid(r.id.iconnext5); iconnext5.setonclicklistener(new onclicklistener() { public void onclick(view v) { intent intent5 = new intent(accountsetup.this, accountsettingactivity5.class); //onnewintent((intent) v.gettag()); intent5.putextra("rowid","5"); startactivity(intent5); finish(); } }); button iconnext6 = (button)findviewbyid(r.id.iconnext6); iconnext6.setonclicklistener(new onclicklistener() { public void onclick(view v) { intent intent6 = new intent(accountsetup.this, accountsettingactivity6.class); //onnewintent((intent) v.gettag()); intent6.putextra("rowid","6"); startactivity(intent6); finish(); } }); button iconnext7 = (button)findviewbyid(r.id.iconnext7); iconnext7.setonclicklistener(new onclicklistener() { public void onclick(view v) { intent intent7 = new intent(accountsetup.this, accountsettingactivity7.class); //onnewintent((intent) v.gettag()); intent7.putextra("rowid","7"); startactivity(intent7); finish(); } }); button iconnext8 = (button)findviewbyid(r.id.iconnext8); iconnext8.setonclicklistener(new onclicklistener() { public void onclick(view v) { intent intent8 = new intent(accountsetup.this, accountsettingactivity8.class); //onnewintent((intent) v.gettag()); intent8.putextra("rowid","8"); startactivity(intent8); finish(); } }); button iconnext9 = (button)findviewbyid(r.id.iconnext9); iconnext9.setonclicklistener(new onclicklistener() { public void onclick(view v) { intent intent9 = new intent(accountsetup.this, accountsettingactivity9.class); //onnewintent((intent) v.gettag()); intent9.putextra("rowid","9"); startactivity(intent9); finish(); } }); button iconnext10 = (button)findviewbyid(r.id.iconnext10); iconnext10.setonclicklistener(new onclicklistener() { public void onclick(view v) { intent intent10 = new intent(accountsetup.this, accountsettingactivity10.class); //onnewintent((intent) v.gettag()); intent10.putextra("rowid","10"); startactivity(intent10); finish(); } }); } @override public void onbackpressed() { intent = new intent(accountsetup.this, welcomeactivity.class); startactivity(i); finish(); super.onbackpressed(); } @override protected void onactivityresult(int requestcode,int resultcode, intent data) { if (requestcode == 100) { if (resultcode == result_ok) { string accountname1 = data.getstringextra("accountname1"); } } } } and following code 2nd activity.

use startactivityforresult() start 2nd activity
startactivityforresult(intent, requestcode) when second activity finished following, intent can hold values need pass activity1
setresult(result_ok, intent) finish(); now on activity1, override onactivityresult()
onactivityresult() { //update textview here. }
