android - Expandable listview setselectionfromTop with animation and padding -

i enabled animation(expand , contract) default android'd expandable listview using https://github.com/idunnololz/animatedexpandablelistview/blob/master/src/com/idunnololz/widgets/animatedexpandablelistview.java.

however, 1 limitation facing move current expanded click top.

i tried setselectionfromtop(groupposition, 0)

here question:
- how add animation bringing top?
- how bring top specific height. lets below 10px top.

any pointers amazing.

note: solution should work sdk 14 , above.

this surely work library used, tired own let me know need sample.

long packedposition = mlistview.getpackedpositionforgroup(groupposition);  final long flatpostion = mlistview.getflatlistposition(packedposition);    expandablelistview.expandgroupwithanimation(groupposition);    new handler().postdelayed(new runnable() {      @override      public void run() {          getactivity().runonuithread(new runnable() {              @override              public void run() {                  mlistview.smoothscrolltopositionfromtop((int) flatpostion, homeactivity.list_header_height, 200);              }          });      }  }, 300);
