android - Adapter not dislpaying correct data -

i new android. develping application in getting large json data server. want display in list view. getting same value repeated. no of items shown list view proper. same data repeated in list items.

here code.

 public class historyactivity extends appcompatactivity { private toolbar toolbar; string strserverresponse = null; progressdialog ndialog; arraylist<string>clicklat; arraylist<string>clicklong; arraylist<string>dttime; arraylist<pojo> history; historyadapter myadapter; listview list; public string date, intime, outtime, inlat, inlong;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);

                }   

and adapter

   public class historyadapter extends baseadapter { private context activity; textview tv_date; textview tv_logintime; textview tv_logouttime; arraylist<pojo> list; private arraylist<pojo> arraylist = null; public static layoutinflater inflater; private context context;   public historyadapter(context a, arraylist<pojo> history) {     // todo auto-generated constructor stub     activity = a;     list = history;     inflater = (layoutinflater) activity.getsystemservice(context.layout_inflater_service);     this.arraylist = new arraylist<pojo>();     this.arraylist.addall(list);  }  @override public int getcount() {     // todo auto-generated method stub     return list.size(); }  @override public object getitem(int position) {     // todo auto-generated method stub     return list.get(position); }  @override public long getitemid(int position) {     // todo auto-generated method stub     return position; }  @override public view getview(int position, view convertview, viewgroup parent) {     // todo auto-generated method stub     view v = convertview;     if(convertview == null) {         v = inflater.inflate(r.layout.history_item, parent, false);     }     final pojo pojo = list.get(position);     tv_date = (textview) v.findviewbyid(r.id.historydate);     tv_logintime = (textview) v.findviewbyid(r.id.historylogintime);     tv_logouttime = (textview) v.findviewbyid(r.id.historylogouttime);     tv_date.settext(pojo.getdate());     tv_logintime.settext(pojo.getlogintime());     tv_logouttime.settext(pojo.getlogouttime());     return v;  }  } 

and setters , getters

   public class pojo { public static string empid11; public static string logintime; public static string date; public static string logouttime; public static list<string> lat; public static list<string> datetime; public static list<string> longi; public static list<string> inlogin; public static list<string> indate; public list<string> getintime(){     return this.inlogin; }  public list<string> getindate(){     return this.indate; } public void setindate(list<string> indate){     this.indate = indate; } public list<string> getlati(){     return this.lat; }  public list<string> getlongi(){     return this.longi; }  public void setlati(list<string> lat){     this.lat = lat; }  public void setlongi(list<string> longi){     this.longi = longi;  } public void setid(string empid) {     this.empid11 = empid; }  public string getid() {     return empid11; }  public void setlogintime(string logintime) {     this.logintime = logintime;  }  public string getlogintime() {     return logintime; }  public void setlogouttime(string logouttime) {     this.logouttime = logouttime; }  public string getlogouttime() {     return logouttime; }  public void setdate(string date) {     this.date = date; }  public string getdate() {     return date; }   public list<string> getdatetime(){     return this.datetime; }  public void setdatetime(list<string> datetime){     this.datetime = datetime; } } 

please me. have tried lot. dont undetstand wrong here.

hello see modifiy version of adapter. let me know if have problem it.

public class historyadapter extends baseadapter  { private context activity; textview tv_date; textview tv_logintime; textview tv_logouttime; private arraylist<pojo> arraylist = null; public static layoutinflater inflater; private context context;   public historyadapter(context a) {     activity = a;     inflater = (layoutinflater) activity.getsystemservice(context.layout_inflater_service);     this.arraylist = new arraylist<pojo>(); }  @override public int getcount() {     return list.size(); }  @override public object getitem(int position) {     return list.get(position); }  @override public long getitemid(int position) {     return position; }  public void addhistorydata(arraylist<pojo> newdataset){     if(arraylist != null){         arraylist.addall(newdataset);     } }  @override public view getview(int position, view convertview, viewgroup parent) {     viewholder mviewholder = null;     if(convertview == null)      {         mviewholder = new viewholder();         convertview = inflater.inflate(r.layout.history_item, parent, false);         mviewholder.tv_date = (textview) convertview.findviewbyid(r.id.historydate);         mviewholder.tv_logintime = (textview)convertview.findviewbyid(r.id.historylogintime);         mviewholder.tv_logouttime = (textview)convertview.findviewbyid(r.id.historylogouttime);         convertview.settag(mviewholder);     }else{         mviewholder = (viewholder) convertview.gettag();     }      final pojo pojo = list.get(position);     mviewholder.tv_date.settext(pojo.getdate());     mviewholder.tv_logintime.settext(pojo.getlogintime());     mviewholder.tv_logouttime.settext(pojo.getlogouttime());     return v; }  public class viewholder{     textview tv_date     textview tv_logintime;     textview tv_logouttime; }  } 

in next activity netcheck class when web service response come change below :

history.add(pojo); myadapter.addhistorydata(history); myadapter.notifiydatasetchanged();
