android - ObjectAnimator onAnimationEnd listener is called before the animation finishes -

its weird , strange, seems when attach animatorlistener objectanimator use animating fragment transactions, callback gets called before finish of animation. use listener populate content fragment (from db). operation take quite long time (~200ms) , when in oncreate or so, destroys animation, because content returned , rendered during animation...there lot of junk , stutter then.. when add populate call listener works when db select takes long time. it's instantaneous , in case have problem when callback called before end of animation. gap between callback , actuall end long enaugh return data db , again destroy fluidness of animation:/

do guys know, how solve issue? below whole code of fragment.

so basicaly there 2 ways how solve issue..i can find solution how populate content fragment without junky animations, or can find way how solve problem listener.

and there 1 way dont like. can create handler , call postdelayed..awful solution:)
