gallery click:

@override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_onclick);   gallery gallery=(gallery)findviewbyid(r.id.gallery1);   gallery.setadapter(new imageadapter(mainactivity.this));    gallery.setonitemclicklistener(new onitemclicklistener() { @override public void onitemclick(adapterview<?> parent, view v,                          int position, long id) { // todo auto-generated method stub  final imageview imageview = (imageview) findviewbyid(r.id.image1);                                         imageview.setimageresource(imageids[position]); } } 

here, when click imageview (imageids[position]) need display imageids1[position] separate images

i tried click imageview (imageids[position]) :

imageview.setonitemclicklistener(new onitemclicklistener()     {     @override     public void onitemclick(adapterview<?> parent, view v,                          int position, long id) {     // todo auto-generated method stub      final imageview imageview1 = (imageview) findviewbyid(r.id.image2);                                             imageview1.setimageresource(imageids1[position]);     } 

but it's not working. need set onitemclick event imageview display imageids1[position] images
