Android - Animate RecyclerView Item of Fragment Inside ViewPager -

i using viewpager fragments. each fragment have recyclerview gridlayoutmanager. inside recyclerview adapter have set animation on onbindviewholder.

problem :

as viewpager loads 2 fragments @ once, animation second fragments gets completed if view not visible

expected output :

when swipe on viewpager recyclerview item should animate.

recyclerview adapter

public void onbindviewholder(viewholder viewholder, final int position) {      viewholder.getserviceimageview().setimageresource(mservices.get(position).getimageresource());     viewholder.getservicenameview().settext(mservices.get(position).getservicename());     viewholder.getpriceperhourview().settext(string.valueof(mservices.get(position).getpriceperhour()));     setanimation(viewholder.serviceitemcontainer, position); }  private void setanimation(view viewtoanimate, int position) {     // if bound view wasn't displayed on screen, it's animated     if (position > lastposition)     {         animation animation = animationutils.loadanimation(mcontext, r.anim.fade_in);         viewtoanimate.startanimation(animation);         lastposition = position;     } } 

fragment code

public view oncreateview(layoutinflater inflater,                          viewgroup container, bundle savedinstancestate) {     view rootview = inflater.inflate(r.layout.fragment_cleaning, container, false);     mrecyclerview = (recyclerview) rootview.findviewbyid(r.id.recyclerview);     mrecyclerview.setlayoutmanager(new gridlayoutmanager(getcontext(), span_count));     mservicesadapter = new recyclerviewadapter(getcontext(), data);     mrecyclerview.setadapter(mservicesadapter);     return rootview; } 

viewpager adapter

private class sectionspageradapter extends fragmentstatepageradapter {      public sectionspageradapter(fragmentmanager fm) {         super(fm);     }      @override     public fragment getitem(int position) {         switch (position) {             case 0:                 fragment = new fragment1();             case 1:                 return new fragment2();             case 2:                 return new fragment3();             default:                 return new fragment4();         }     }      @override     public int getcount() {         return 4;     }      @override     public charsequence getpagetitle(int position) {         locale l = locale.getdefault();         switch (position) {             case 0:                 return getstring(r.string.title_section1).touppercase(l);             case 1:                 return getstring(r.string.title_section2).touppercase(l);             case 2:                 return getstring(r.string.title_section3).touppercase(l);             case 3:                 return getstring(r.string.title_section4).touppercase(l);         }         return null;     } 

can suggest me how this?

try this

1. implement own onresumefragment() @ activity of fragment want animate
2. at onresumefragment() call adapter.notifydatasetchanged(); start animations
