问题 I have a shared element in a fragment that belongs to one Activity. I want to make a shared element transition in Android Lollipop with an element that is part of a fragment that belongs to another activity. Is it possible? How can I achieve that? 回答1: It's possible.

问题 I have two views in a linear layout, I programmatically change their layout_weight property. Is there a way I could animate this change in weight so when the weight is changed views slides towards a new size? 回答1: You can simply use ObjectAnimator.

To address this
