lazylist - Android ListView ArrayAdapter -

i'm trying use lazylist load images , i'm using array datas. cant figure out how implement view holder. please check codes below. line of code

imageloader.displayimage(worldpopulationlist.get(position).getflag(), holder.flag); 

the method displayimage(string, imageview) in type imageloader not applicable arguments (int, imageview)

worldpopulation

public class worldpopulation {     private string rank;     private string country;     private string population;     private int flag;      public worldpopulation(string rank, string country, string population,             int flag) {         this.rank = rank;         this.country = country;         this.population = population;         this.flag = flag;     }      public string getrank() {         return this.rank;     }      public string getcountry() {         return this.country;     }      public string getpopulation() {         return this.population;     }      public int getflag() {         return this.flag;     } } 

as getting

the method displayimage(string, imageview) in type imageloader not applicable arguments (int, imageview)

means worldpopulationlist.get(position).getflag() returning integer value instead of image url. make sure using right getter/setter image url.

imageloader.displayimage(string,imageview) method takes 2 parameter first string url image , second imageview instance want set downloaded image
