java - Android - how can i from window1 go to window2 then go to window3 from window3 jump back to window1? -

i have 3 window (activity). window1 buttons old pictures, window2 options change old pictures of window1, window3 preview of pictures.

when selection made in window3 want skip quite window2 + window3 , jump window1. how can that?

window1:

intent myrotationsaddpicture2 = new intent(getbasecontext(), myrotationsaddpicture.class); myrotationsaddpicture2.putextra("title", "r2.jpg"); startactivityforresult(myrotationsaddpicture2,0); 

window2 / window3 ?

string whichimage =  getintent().getextras().getstring("title");   protected void onactivityresult(int requestcode, int resultcode, intent data) {       if (resultcode == 0) {       finish();       startactivity(getintent());      } }  setresult(0); this.finish(); system.exit(0); 

from looks want don't want use startactivityforresult() here...just use startactivity().

in activity3 use

intent intent = new intent(activity3.this, activity1.class); intent.setflags(intent.flag_activity_reorder_to_front); startactivity(intent); 

use if don't want remove activity2 stack.

if want remove activity2 stack use flags

intent.setflags(intent.flag_activity_reorder_to_front|intent.flag_activity_clear_top); 

or call finish() in activity2 when moving activity3

you can find of intent flags here in docs
