ObjectAnimator onAnimationEnd listener is called before the animation finishes

Question

its weird and strange, but it seems like when I attach an AnimatorListener to an ObjectAnimator I use for animating fragment transactions, the callback gets actually called slightly before finish of the animation. I use the listener to populate content into the fragment (from DB). The operation could take quite long time (~200ms) sometimes and when I do it in onCreate or so, it just destroys the animation, because the content is returned and rendered during the animation...there is lot of junk and stutter then.. So when I add the populate call into the listener it works when also the DB select takes long time. But sometimes it's nearly instantaneous and in that case I have problem when the callback is called before the end of the animation. The gap between the callback and the actuall end is long enaugh to return the data from DB and again destroy fluidness of the animation:/

Do you guys know, how to solve this issue? Below is nearly whole code of that Fragment.

So basicaly there are two ways how to solve this issue..I can find completely another solution how to populate the content to the fragment without junky animations, or I can find a way how to solve the problem with the listener.

And there is one extra way I dont like. I can create a Handler and call postDelayed..awful solution:)
