java - Issue in ArrayList in android -

in app using arraylist save string values.these values taken asynctask , these values set textview in adapter.but set values second position in arraylist.in log showing arraylist values contains values.but while setting not display first value.code mentioned below.

indexofselectedid = photoall_id.indexof(photoid_c);  (int = indexofselectedid ; < photoall_id.size(); i++) {     all_postid.add(photoall_id.get(i));     url = urls.baseurl + "mobile_api.php?action=post&post_id=" + photoall_id.get(i) + "&access_token=" + accesstoken + "&user_id=" + userid;      new getimage().execute(url);   }  (int = 0; < indexofselectedid; i++) {      all_postid.add(photoall_id.get(i));     url = urls.baseurl + "mobile_api.php?action=post&post_id=" + photoall_id.get(i) + "&access_token=" + accesstoken + "&user_id=" + userid;       new getimage().execute(url);   }   adapter = new imagepageradapter ();  viewpager.setadapter(adapter);  private class getimage extends asynctask<string, void, arraylist<string>> {  string json = null; arraylist<string> all_data; @override protected void onpreexecute() {     all_data=new arraylist<>();      showprogress("loading images....");     super.onpreexecute(); }  @override protected void onpostexecute(arraylist<string> avoid) {      //   touchimageview.setimagebitmap(bitmap);   dismissprogress();          all_url.add(avoid.get(0));      all_cap.add(avoid.get(1));     }  @override protected arraylist<string> doinbackground(string... params) {      jsonreader reader = new jsonreader();     json = reader.getjsonget(params[0]);      if (json != null) {         try {             jsonobject object = new jsonobject(json);             if (object.getjsonarray("posts").getjsonobject(0).getint("count") != 0) {                  photo_url = object.getjsonarray("posts").getjsonobject(0).getstring("photo_url");                 photo_caption = object.getjsonarray("posts").getjsonobject(0).getstring("photo_caption");               }             all_data.add(photo_url);             all_data.add(photo_caption);           } catch (jsonexception e) {             e.printstacktrace();         }     }      return all_data; } 

}

private class imagepageradapter extends pageradapter { imageview imageview;

@override public int getcount() {     return all_url.size(); }  @override public boolean isviewfromobject(view view, object object) {     return view == object; }  @override public object instantiateitem(viewgroup container, int position) {     context context = fullscreenactivity.this;     layoutinflater inflater = (layoutinflater)context.getsystemservice(context.layout_inflater_service);     view viewlayout = inflater.inflate(r.layout.item, container,             false);        imageview = (imageview)viewlayout. findviewbyid(r.id.cardimage);      int padding = context.getresources().getdimensionpixelsize(             r.dimen.padding_medium);     imageview.setpadding(padding, padding, padding, padding);     imageview.setscaletype(imageview.scaletype.center_inside);      log.d("caption testingggggggggfgfgf", all_upuser.get(position));     picasso.with(context).load(all_url.get(position)).into(imageview);     current_postid=all_postid.get(position);             string temp_cap=all_cap.get(position);          image_head.settext(temp_cap);         ((viewpager) container).addview(viewlayout, 0);      return viewlayout; }  @override public void destroyitem(viewgroup container, int position, object object) {      ((viewpager) container).removeview((view) object);  } 

}

and log is
