android - How to persist the state of switches within a List view -

this first attempt @ using list views , have created list view containing switches. whenever navigate away activity state of switches reset default value. list view contains 4 switches , many of answers have came across deal problem of switches resetting state when out of view.

i have thought creating array , storing state of each switch , loading state when user navigates activity. have advice how best achieve this?

public view getview(final int position, view convertview, viewgroup    parent) {     view view;      if (convertview == null) {         view = minflater.inflate(r.layout.options_list_item, parent,   false);     } else {         view = convertview;     }      symbols m1 = getitem(position);      switch optionsswitch = (switch) view.findviewbyid(r.id.switch2);      optionsswitch.setoncheckedchangelistener(new compoundbutton.oncheckedchangelistener() {         public void oncheckedchanged(compoundbutton buttonview, boolean ischecked) {             if (ischecked && position == 0) {                 state = true;             } else {                 state = false;             }         }     });      return view; }  

there no best way achieve thoughts great, infact best judge know best fit design model , app design etc,

but persist data through talked sharedpreferences, disk or in heap memory stated.

hope helps
