animation - android animating buttons from offscreen bottom to onscreen are blank -

-

i have relativelayout container 5 buttons on it.

when use translationanimation offscreen (below screen), buttons blank until animation done. @ end of animation, explicitly draw buttons , appear in correct locations.

i have similar container , buttons animated onscreen right offscreen. container shows of buttons during animation , after expect to.

also, when animate first set of buttons down offscreen location below, visible during entire animation.

the problem happens when animating below screen onscreen.
