Hey @bitsydarel !!
I initially thought that the reason is the anonymous inner-type class in custom(--)
method.
But I was wrong.
The reason is the 2nd parameter of the custom(-,-...)
method is float... values
;
i.e., it is expecting the valueAnimator float array values which you are not passing & is thus erroring out in your animation with Attempt to get length of null array..
exception.
Let us know if this fixes your issue :)
Cheers 👍
Hi, trying to animate by button with the following code but getting null exception not from my code but from internal code.
ViewAnimator.animate(binding.liveFavorite) .zoomIn() .fadeOut() .custom(AnimationListener.Update { view, _ -> view.setImageResource(R.drawable.ic_bookmarked) } )
.fadeIn()
.zoomOut()
.start()
