android - highlight previous selected item when user come back from another activity -


activity1 has listview. clicking 1 item (let's item 3) start activity2. activity2 have button once clicked bring user activity1. want achieve highlight item 3 when user activity1 user have sense continue. (may need set focus item 3 well.)

edit: following code works.

   public void onresume() {     super.onresume();       //lastselectedposition saved in onitemclicklistener     lv.setselection(lastselectedposition);     lv.requestfocusfromtouch();  }

well pretty simple. save clicked item position of list field when list clicked launch new activity.

afterwards in onresume() method use mylist.setselection(savedposition);

as highlighting, focus works kinda bad if have bit more complex rows(buttons,checkboxes etc) , other ui elements beside list can take away focus. believe best way achieve set background of particullar item onresume highlighted 1 , override onscroll listener change background default when list scrolled. indeed workaround work in 100% of cases opposite focusing item. plus maybe can add animations on view can make nice , smooth.
