}

change gridview.setchoicemode(listview.choice_mode_multiple); to

gridview.setchoicemode(gridview.choice_mode_multiple_modal);

grid view can homecoming image's id , position respect grid view , not respect xml.

to id of image in grid view

gridview.setonitemclicklistener(new adapterview.onitemclicklistener() { @override public void onitemclick(adapterview<?> parent, view v, int position, long id) { toast.maketext(getapplicationcontext(), "id , position = "+id+" "+position, toast.length_long).show(); } });
