android - Using sharedPreferences with a material spinner to update activities -

i found amazing material spinner online , able modify code:

<fr.ganfra.materialspinner.materialspinner         android:id="@+id/spinner"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         app:ms_multiline="false"         app:ms_basecolor="@color/off"         app:ms_highlightcolor="@color/off"         app:ms_hintcolor="@color/off"         app:ms_arrowcolor="@color/off"         app:ms_arrowsize="16dp"         app:ms_alignlabels="false"         app:ms_floatinglabelcolor="@color/off"/> 

so used sharedpreferences store whatever value user chooses spinner when page called again, choice on spinner face. how add preferences in oncreate:

 @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.settings);  string[] items = {"daily", "weekly", "monthly"};     arrayadapter<string> adapter = new arrayadapter<string>(this, android.r.layout.simple_spinner_item, items);     adapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item);     spinner = (materialspinner)findviewbyid(r.id.spinner);     spinner.setadapter(adapter);     spinner.seterror(null);  spinpref=getsharedpreferences("frequency", mode_private);             spinedit=spinpref.edit();             spinner.setonitemselectedlistener(new adapterview.onitemselectedlistener() {                 @override                 public void onitemselected(adapterview<?> parent, view view, int position, long id) {                     if (position == 1) {                         int freq1 = 1;                         spinedit.putint("freq", freq1);                         spinedit.apply();                     } else if (position == 2) {                         int freq2 = 2;                         spinedit.putint("freq", freq2);                         spinedit.apply();                     } else if (position == 3) {                         int freq3=3;                         spinedit.putint("freq", freq3);                         spinedit.apply();                     }                 }                  @override                 public void onnothingselected(adapterview<?> parent) {                     int freq0 = 0;                     spinedit.putint("freq", freq0);                     spinedit.apply();                 }              });             finish(); } 

then in onresume, this:

@override protected void onresume() {      spinpref=getsharedpreferences("frequency",mode_private);     int num=spinpref.getint("freq", 0);     spinner.setselection(num); } 

but spinner shows first value, how make work? don't think sharedprefs wrong, may onitemselected() , i'm not sure how else this? ps: tried replacing line each of positions as

spinedit.putint("freq", position); 

instead of have there right now:

spinedit.putint("freq", freq); 

but didn't work either. ideas or material willing bring light me please? appreciate much

what i'm proposing (in comment above):

public class myactivity extends activity {     sharedpreferences spinpref;     editor spinedit;      //prevent typos     private static final string pref_name = "frequency";     public static final string frequency = "freq";       @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.settings);          //init prefs         spinpref=getsharedpreferences(pref_name, 0);         spinedit=spinpref.edit();          //init spinner         ...          //set listener         ...     }      @override     protected void onresume() {         int num=spinpref.getint(frequency, 0);         spinner.setselection(num);     }  }
