android - How to solve array out of bound exception? -

this code , getting array out of bound exception.how solve error?i used bitmap object instead of string .when store bitmap image array list got error.

mainactivity.java

public class mainactivity extends activity {     listview lv;     context context;      arraylist prgmname;     bitmap bitmap;     //bitmap=getbitmapfromurl("http://content6.flixster.com/movie/11/17/75/11177548_pro.jpg");      public static string [] prgmnamelist={"let c","c++","java","jsp","microsoft .net","android","php","jquery","javascript"};     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         bitmap=getbitmapfromurl("http://content6.flixster.com/movie/11/17/75/11177548_pro.jpg");         context=this;         bitmap  [] prgmimages ={bitmap,bitmap};         lv=(listview) findviewbyid(r.id.listview);         lv.setadapter(new customadapter(this, prgmnamelist,prgmimages));      }       @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.main, menu);         return true;     }     private bitmap getbitmapfromurl(string src) {         // todo auto-generated method stub         try {              url url =new url(src);             httpurlconnection connection = (httpurlconnection) url.openconnection();             connection.setdoinput(true);             connection.connect();             inputstream input=connection.getinputstream();             bitmap mybibitmap=bitmapfactory.decodestream(input);             return mybibitmap;            } catch (exception e) {             // todo: handle exception            e.printstacktrace();            return null;          }       }  } 

customeradapter.java

public class customadapter extends baseadapter{     string [] result;     context context;  bitmap[] imageid;       private static layoutinflater inflater=null;     public customadapter(mainactivity mainactivity, string[] prgmnamelist, bitmap[] prgmimages) {         // todo auto-generated constructor stub         result=prgmnamelist;         context=mainactivity;         imageid=prgmimages;          inflater = ( layoutinflater )context.                  getsystemservice(context.layout_inflater_service);     }     @override     public int getcount() {         // todo auto-generated method stub         return result.length;     }      @override     public object getitem(int position) {         // todo auto-generated method stub         return position;     }      @override     public long getitemid(int position) {         // todo auto-generated method stub         return position;     }      public class holder     {         textview tv;         imageview img;     }     @override     public view getview(final int position, view convertview, viewgroup parent) {         // todo auto-generated method stub         holder holder=new holder();         view rowview;                      rowview = inflater.inflate(r.layout.list_item, null);              holder.tv=(textview) rowview.findviewbyid(r.id.textview1);              holder.img=(imageview) rowview.findviewbyid(r.id.imageview1);                 holder.tv.settext(result[position]);          holder.img.setimagebitmap(imageid[position]);                   rowview.setonclicklistener(new onclicklistener() {                      @override             public void onclick(view v) {                 // todo auto-generated method stub                 toast.maketext(context, "you clicked "+result[position], toast.length_long).show();             }         });           return rowview;     }  } 

you getting arrayindexoutofbound because imageid don't have same array size of result.

you can see result array has 9 element , imageid has 2 element, , both element same, why using array, pass simple bitmap instead of array.

your result array:

 public static string [] prgmnamelist={"let c","c++","java","jsp","microsoft .net","android","php","jquery","javascript"}; 

your imageid array:

 bitmap  [] prgmimages ={bitmap,bitmap}; 

solution :

1) if want display different images row item pass imageid array same size of result array. 2) if want display same image in row item pass single bitmap instead of array.
