动画LayoutParams与Android中的翻译和缩放

Question

It seems like the code for animating a view's scale and translation is always much more clean and concise (eg using .animate() ) than code that animates the view's LayoutParams (ie width, height, etc.) which requires the use of animators ( ValueAnimator , ObjectAnimator , etc.)

That made me wonder whether animating a certain view's LayoutParams is considered a bad practice, or if it's "heavier" than animating the view's translation and scale properties?

Also, couldn't find any answers for this on SO so it would be great if anyone could shed some light on the subject.

Answer 1

如@pskink所述，在活动/片段/布局内执行转场和动画的一种更干净的方法是使用场景和转场，这正是我所做的，并且经过一些调整才可以完美地工作！

Answer 2

如果您具有更复杂的布局，并尝试通过layoutParams进行动画处理，您将很快看到结结，因为在每一帧上都会触发requestLayout()并且父ViewGroup必须为整个视图层次结构执行onMeasure()和onLayout() 。
