Refine animation to remove strange reshuffling animation

The issue happens mainly because two animations(move + change) running
on the same view interrupt with each other. When ItemAnimator runs the
move animation, it will change the translationX&Y in a time period.
When the change animation occurs in this period, it gets this translation
value and calculates a non-zero deta, then it would run an unnecessary
move animation, which causes the strange reshuffling.

In this cl, I skip the translation value only for the tile view when
there is pending animation.

I also add scroll operation for conditions view to make it scroll to
top after condition change.
