I understand that animating a View using startAnimation() with a TranslateAnimation object really just applies a transform on the canvas that is being drawn on. In my case, the problems with this are: a) sometimes I need to call bringChildToFront() (for a different View) on the ViewGroup during the animation, which messes up the animation because it triggers a requestLayout on all children, which in turn re- lays out the child being animated... which messes up the continuity of the animation. Perhaps causing a layout on the child being animated isn't supposed to mess up animations, but it seems to be in my case. b) after the animation (using an AnimationListener), I need to re- layout the child to the new location, which is fine in concept, but again messes up the animation because for some reason the actual drawing of the last frame of the animation hasn't finished by the time onAnimationEnd() is called. This causes the animation to go awry at the very end. What's happening in my case is if I layout the animated view to its new location in onAnimationEnd, the last step of the animation is being applied to the new layout, so the view looks like it is jumping around the screen. I tried a handler with no delay, and that didn't work either. Using a handler with a delayed message to accomplish the new layout works but is such a hack that I worry it may not work correctly on another piece of hardware.
I could accomplish the animation by taking out the TranslateAnimation and instead do a manual animation, and in the manual one, change the layout of the view gradually (instead of transforming the matrix of the canvas) but that's a lot of work and error-prone. Any ideas? Are there tools I can use (besides manual application of Handler.sendMessageDelayed()) to accomplish an animation that actually re-lays out the view on each iteration instead of altering the canvas matrix? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
