imageviewpager.java:

public class imageviewpager extends activity {     // declare variable     int position;     textview textview;      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         // set title viewpager         settitle("viewpager");         // view view_pager.xml         setcontentview(r.layout.view_pager);          // retrieve data mainactivity on item click event         intent p = getintent();         position = p.getextras().getint("id");                    textview = (textview) findviewbyid(r.id.textview1);                       imageadapter imageadapter = new imageadapter(this);         list<imageview> images = new arraylist<imageview>();          // retrieve images         (int = 0; < imageadapter.getcount(); i++) {             imageview imageview = new imageview(this);             imageview.setimageresource(imageadapter.mthumbids[i]);             imageview.setscaletype(imageview.scaletype.center);             images.add(imageview);         }          // set images viewpager         imagepageradapter pageradapter = new imagepageradapter(images);         viewpager viewpager = (viewpager) findviewbyid(r.id.pager);         viewpager.setadapter(pageradapter);         // show images following position         viewpager.setcurrentitem(position);     } } 

you shoul set text onpageselected.

  viewpager.setonpagechangelistener(new onpagechangelistener() {          @override         public void onpageselected(int arg0) {             // todo auto-generated method stub             system.out.println("current position=="+num);             textview.settext((arg0+1)+" of "+ images.size());         }          @override         public void onpagescrolled(int arg0, float arg1, int arg2) {             // todo auto-generated method stub              system.out.println("onpagescrolled");         }          @override         public void onpagescrollstatechanged(int num) {             // todo auto-generated method stub           }     });
