gridview - android viewpager like image gallery -

im trying create image gallery.

i have viewpager each fragment contains image (swipable image gallery im trying accomplish). have gridview onitemclick triggers viewpager in selected position showing clicked image. problem 1 swipe right , 1 swipe left shows same image clicked one. ive tried setoffscreenpagelimit no success. viewpager activity:

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_image_gallery);     helper = new weddhelper(this,"wedd.db",null,1);     pager = (viewpager) findviewbyid(r.id.pager);     pager.setonpagechangelistener(this);     intent ing = getintent();     curr = ing.getintextra("curr", 0);     byto = helper.getphotos();     count = byto.size();     fragmentmanager mg = getsupportfragmentmanager();    fragments = new vector<fragment>();     for(int = 0; i<count;i++){ fragments.add(fragment.instantiate(this,galleryfrag.class.getname()));                 }     madapter = new fragmentadapter(getsupportfragmentmanager(), fragments, this);     pager.setadapter(madapter);     pager.setoffscreenpagelimit(1);     pager.setcurrentitem(curr); }  @override public void onpagescrolled(int position, float positionoffset, int positionoffsetpixels) {  }  @override public void onpageselected(int position) {     mcurrentposition = position;     curr = position; }  @override public void onpagescrollstatechanged(int state) {  } public int getclicked(){     return curr; } public byte[] getphototobedisplayed(){      return byto.get(curr); } } 

this custom adapter:

public class fragmentadapter extends fragmentstatepageradapter {  private list<fragment> fragments=null; private fragmentmanager fragmentmanager=null; private context context;  public fragmentadapter(fragmentmanager fragmentmanager,list<fragment> fragments, context context) {     super(fragmentmanager);     this.fragments=fragments;     this.fragmentmanager=fragmentmanager;     this.context = context; }  @override public fragment getitem(int position) {     return fragments.get(position);  } @override public int getcount() {     return fragments.size();  } @override public void setprimaryitem(viewgroup container, int position, object object) {     super.setprimaryitem(container,0,object); } @override public void notifydatasetchanged() {     super.notifydatasetchanged(); } @override public void destroyitem(viewgroup collection, int position, object view) {     fragmentmanager.executependingtransactions();     fragmentmanager.savefragmentinstancestate(fragments.get(position)); } public void replaceitem(int position,fragment fragment) {     fragments.set(position, fragment);     this.notifydatasetchanged(); } } 

and fragment:

public class galleryfrag extends fragment { weddhelper helper;  @nullable @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     view v = inflater.inflate(r.layout.gallery_fragment, container, false);     imagegallery myactivity = (imagegallery) getactivity();     int curr = myactivity.getclicked();     byte[] phototobedisplayed = myactivity.getphototobedisplayed();     helper = new weddhelper(getactivity(),"wedd.db", null, 1);     arraylist<byte[]> imgs = helper.getphotos();     bitmap br = bitmapfactory.decodebytearray(phototobedisplayed,0,phototobedisplayed.length);     bitmap bi = bitmapfactory.decodebytearray(imgs.get(curr),0,imgs.get(curr).length);     toast.maketext(getactivity(), curr+"this frag", toast.length_short).show();     imageview iv = (imageview) v.findviewbyid(r.id.fragimage);     iv.setimagebitmap(br);     return v; } }
