java - The constructor Object(Context, int, List<DrawerItem>) is undefined -


please me resolve issue. i'm making drawer app , i'm receiving these errors adt:

  • the constructor object(context, int, list) undefined

  • the method getview(int, view, viewgroup) of type customdraweradapter must override or implement supertype method

this code customdraweradapter class:

package com.example.ico; import java.util.list; import android.app.activity; import android.content.context; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.widget.arrayadapter; import android.widget.imageview; import android.widget.textview;  public class customdraweradapter {       context context;      list<draweritem> draweritemlist;      int layoutresid;       public customdraweradapter(context context, int layoutresourceid, list<draweritem> listitems) {          super(context, layoutresourceid, listitems);            this.context = context;            this.draweritemlist = listitems;            this.layoutresid = layoutresourceid;       }       @override      public view getview(int position, view convertview, viewgroup parent) {            // todo auto-generated method stub             draweritemholder drawerholder;            view view = convertview;             if (view == null) {                  layoutinflater inflater = ((activity) context).getlayoutinflater();                  drawerholder = new draweritemholder();                   view = inflater.inflate(layoutresid, parent, false);                  drawerholder.itemname = (textview) view                              .findviewbyid(r.id.drawer_itemname);                  drawerholder.icon = (imageview) view.findviewbyid(r.id.drawer_icon);                   view.settag(drawerholder);             } else {                  drawerholder = (draweritemholder) view.gettag();             }             draweritem ditem = (draweritem) this.draweritemlist.get(position);             drawerholder.icon.setimagedrawable(view.getresources().getdrawable(                        ditem.getimgresid()));            drawerholder.itemname.settext(ditem.getitemname());             return view;      }       private static class draweritemholder {            textview itemname;            imageview icon;      }   }

to fix problems, need make class extend arrayadapter.

public class customdraweradapter extends arrayadapter {
