Android Gridview Selection not working -

when clicking icon in gridview, showing " clicked this". instead need go new page corresponding icon.

here code

mainactivity.java

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     gv=(gridview) findviewbyid(r.id.gridview1);     gv.setadapter(new customadapter(this, prgmnamelist,prgmimages)); }  @override public boolean oncreateoptionsmenu(menu menu) {     // inflate menu; adds items action bar if present.     getmenuinflater().inflate(r.menu.menu_main, menu);     return true; }  @override public boolean onoptionsitemselected(menuitem item) {     // handle action bar item clicks here. action bar     // automatically handle clicks on home/up button, long     // specify parent activity in androidmanifest.xml.     int id = item.getitemid();      //noinspection simplifiableifstatement     if (id == r.id.action_settings) {         return true;     }      return super.onoptionsitemselected(item); } 

}

and customadapter.java

public customadapter(mainactivity mainactivity, string[] prgmnamelist, int[] prgmimages) {      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.programlist, null);     holder.tv=(textview) rowview.findviewbyid(r.id.textview1);     holder.img=(imageview) rowview.findviewbyid(r.id.imageview1);      holder.tv.settext(result[position]);     holder.img.setimageresource(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; } 

}

what changes should make ?

implement adapterview.onitemclicklistener in main activity , set listener gridview gridview.setonitemclicklistener(this);. better handle click events on each item.
