android - How to get value of current array adapter position other than in getView -

-

i using cardstack through array adapter. using getter setters display data on card. getting duration of song associated card getsongduration(). problem when loads , in getview method do:

songduration = item.getsongduration();

and log value, being called multiple times different positions.

i need value song duration current song. use notify dataset changed instance not see how applies.

this adapter:

  public class songpreviewcardsdataadapter extends arrayadapter<songdatabasemappingadapter> {      private context mcontext;      public songpreviewcardsdataadapter(context context, int resource) {         super(context, resource);          mcontext = context;      }      imagebutton onestarrating;     imagebutton twostarrating;     imagebutton threestarrating;     imagebutton fourstarrating;     imagebutton fivestarrating;       @override     public int getcount() {         return super.getcount();     }      @override     public view getview(int position, final view contentview, viewgroup parent) {         // initialise song views        final songdatabasemappingadapter item = getitem(position);           long songduration = item.getsongduration();         log.d ("duration", ""+songduration);              textview songname = (textview) (contentview.findviewbyid(r.id.songnametextview));         textview artist_albumname = (textview) (contentview.findviewbyid(r.id.artist_albumview));         com.mikhaellopez.circularimageview.circularimageview songimage = (circularimageview) contentview.findviewbyid(r.id.songimageview);        string imageurl = (item.getpictureurl());        picasso                 .with(this.getcontext())                 .load(imageurl)                 .into(songimage);         final circularprogressbar circularprogressbar = (circularprogressbar)contentview.findviewbyid(r.id.songprogresswheel);        circularprogressbar.setcolor(contextcompat.getcolor(getcontext(), r.color.darkred));
