mainactivity.java (here images displaying in gridview)

public class mainactivity extends actionbaractivity {      private listview listview;     private gridview gridview;       @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.grid_layout);         // listview = (listview)findviewbyid(r.id.gridview);         gridview = (gridview) findviewbyid(r.id.gridview);         gridview.setadapter(new imagelistadapter(this));            gridview.setonitemclicklistener(new adapterview.onitemclicklistener() {             @override             public void onitemclick(adapterview<?> parent, view view, int position, long id) {                intent = new intent(getapplicationcontext(), fullimageactivity.class);                i.putextra("id", position);                startactivity(i);              }         });      }  }

public class fullimageactivity extends activity {     @override     public void oncreate(bundle savedinstancestate) {          super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_full_image);          intent = getintent();         int position = i.getextras().getint("id");         imagelistadapter imageadapter = new imagelistadapter(this);         imageview imageview = (imageview)                 findviewbyid(r.id.full_image_view);         imageview.setimageresource(integer.parseint(imageadapter.urls[position]));     }  }
