android using ViewPager to show images -

i'd download bunch of images web , show them using custom pageradapter. can slide browse of these images.

i define activity named photoslideactivity extends fragmentactivity. in activity, have own pageradapter. following code:

    private class photoslidepageradapter extends fragmentstatepageradapter {         private final int msize;          public photoslidepageradapter(fragmentmanager fm, int size) {             super(fm);             msize = size;         }          @override         public fragment getitem(int position) {             photourl photourl = new photourl(position);             return photoslidepagefragment.create(photourl.makephotourl());         }          @override         public int getcount() {             return msize;         }     } 

the following photoslidepagefragment. mimagefetcher class download images asynchronously.

   public class photoslidepagefragment extends fragment {     @override    public view oncreateview(layoutinflater inflater, viewgroup container,         bundle savedinstancestate) {        final view v = inflater.inflate(r.layout.fragment_photo_slide_page, container, false);        mimageview = (imageview) v.findviewbyid(r.id.imageview1);    }     @override    public void onactivitycreated(bundle savedinstancestate) {        super.onactivitycreated(savedinstancestate);         // use parent activity load image asynchronously imageview        if (photoslideactivity.class.isinstance(getactivity())) {           mimagefetcher = ((photoslideactivity) getactivity()).getimagefetcher();           mimagefetcher.loadimage(mimageurl, mimageview);        }    } 

(1) original idea put mimagefetcher.loadimage(mimageurl, mimageview); in oncreateview. there difference between putting in oncreateview , in onactivitycreated?

(2) if replace did in onactivitycreated mimagefetcher = new imagefetcher(); mimagefetcher.loadimage(mimageurl, mimageview);? doing means use fragment load image asynchronously. there bad effects doing this?

use can use lazylist fetch data website(url). download following example github

and adapter data use in swipe change image example
