android - Scrollview does not work on viewpager.pagetransformer -

i'm working viewpager fragments scrollview fade in- out animation.for purpose add function on viewpager.pagetransformer.when add feature scroll view not work properly(only first step data scroll ).

declaration on viewpager:

    mviewpager = (viewpager) findviewbyid(r.id.pager);     msectionspageradapter = new sectionspageradapter(getsupportfragmentmanager());     mviewpager.setpagetransformer(true, new crossfadepagetransformer());     mviewpager.setadapter(msectionspageradapter); 

sectionspageradapter class are:

public class sectionspageradapter extends fragmentpageradapter {      public sectionspageradapter(fragmentmanager fm) {         super(fm);     }      @override     public fragment getitem(int position) {         // getitem called instantiate fragment given page.         // return placeholderfragment (defined static inner class         // below).         return placeholderfragment.newinstance(position + 1);     }      @override     public int getcount() {         // show 3 total pages.         return 3;     }  } 

and crossfadepagetransformer class fade in-out animation :

public class crossfadepagetransformer implements viewpager.pagetransformer {  @targetapi(build.version_codes.ice_cream_sandwich) @suppresslint("newapi") @override public void transformpage(view view, float position) {      //working.....     view.setscrolly(0);     view.settranslationx(view.getwidth() * -position);     if (position <= -1.0f || position >= 1.0f) {         view.setalpha(0.0f);     } else if (position == 0.0f) {         view.setalpha(1.0f);     } else {         // position between -1.0f & 0.0f or 0.0f & 1.0f         view.setalpha(1.0f - math.abs(position));     } } 

how can solve issues?please suggest me.thanks all.

the thing viewpager implements ontouchevent, same scrollview, interfere each other.

i'm afraid there no easy way make work, don't use nested scroll views.
