android - TabLayout selected tab gravity -

tablayout set viewpager, has lot of tabs, mode_scrollable , keyline app:tabcontentstart="72dp".

when user selects tab, tablayout tries scroll selected tab center. selected tab left aligned keyline, not centered. possible?

android design support library v22.2.0.

unfortunately method calculatescrollxfortab() of tablayout private , not replaceable subclasses. either way can copy source tablayout in project, possibly extending class, , change method calculatescrollxfortab() this:

private int calculatescrollxfortab(int position, float positionoffset) {    if (mmode == mode_scrollable) {       view final selectedchild = mtabstrip.getchildat(position);       // log.i ("scrollto" string.valueof ((int) selectedchild.getleft()));       return (int) selectedchild.getleft();    }    return 0; } 

this returns value of limit on left of tab selected, scrolling forced value. extreme right tabs remain fixed in position if selected because scroll clamps scrolling bounds of child.

i tried , works, although had solve 2 problems 1 compattextview not found in android.support.v7.internal.widget , method setupwithviewpager() not exist in source available me (i think matter of version)
