android listview fling animation is too fast -

i have custom listview shows items "page page". i've written ontouch method , works perfect, want write onfling method realize smooth , inertial scrolling of listview.

the problem scrolling animation of smoothscrolltoposition(int position) isn't smooth, it's fast. smoothscrolltoposition(int position, int offset, int duration) works, minsdk must 8 , besides functions place current element badly despite on offset.

this code of onfling method:

@override public boolean onfling(motionevent e1, motionevent e2, float velocityx, float velocityy)  {         if(null == getadapter()) return false;          boolean returnvalue = false;         float pty1 = 0, pty2 = 0;          if (e1 == null || e2 == null)             return false;          pty1 = e1.gety();         pty2 = e2.gety();          if (pty1 - pty2 > swipemindistance && math.abs(velocityy) > swipethresholdvelocity)          {             float currentvelocity = math.min(math.abs(velocityy), math.abs(swipemaxvelocity));              final int shift = (int) ((currentvelocity / swipemaxvelocity) * swipemaxelements + 1);              if (activeitem < getadapter().getcount() - shift - 1)                 activeitem = activeitem + shift;             else             {                 activeitem = getadapter().getcount() - 1;                 return false;             }              returnvalue = true;         }          else if (pty2 - pty1 > swipemindistance && math.abs(velocityy) > swipethresholdvelocity)          {             float currentvelocity = math.min(math.abs(velocityy), math.abs(swipemaxvelocity));              final int shift = (int) ((currentvelocity / swipemaxvelocity) * swipemaxelements + 1);              if (activeitem >= shift)                 activeitem = activeitem - shift;             else             {                 activeitem = 0;                 return false;             }              returnvalue = true;         }         smoothscrolltoposition(activeitem);         return returnvalue;     } 

the xml content is:

<?xml version="1.0" encoding="utf-8"?>  <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"   android:id="@+id/rl_main"   android:layout_width="match_parent"   android:layout_height="match_parent">   <konteh.example.errortest.cardslistview      android:id="@+id/cardslistview"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_alignparentleft="true"      android:layout_alignparenttop="true"      android:smoothscrollbar="true"       /> 

solved! solution is:

    int pixelcount = height * shift * (isforward ? 1 : -1); // calculate approximately shift in pixels     smoothscrollby(pixelcount, 2 * duration * shift);//this smooth scroll works!     postdelayed(new runnable()      {         public void run()          {             smoothscrollby(0, 0); // stops listview overshooting.             smoothscrolltoposition(activeitem + 1);         }     },      duration * shift); 

maybe it's not best solution, works!
