android-animation

问题 I currently have a working Android program that programmatically adds views to a LinearLayout. I would like those views to be animated in and cannot find any good resources on figuring out how to do this. Could someone point me in the right direction? 回答1: It's a very old question, but still interesting: you can use the attribute android:animateLayoutChanges="true" For example: <LinearLayout android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="wrap

问题 My problem is, that I constantly get the warning W/MotionLayout: WARNING could not find view id -1 . Because of this, my MotionLayout is really laggy and nearly jumps from the expanded state to the collapsed state .

问题 I am developing an application in which should have a vertical Recyclerview in which the items will be enlarged when touched by users and decreased when the user releases them. In my research I have not found a way to build it. The most similar to what I look for are the Facebook reactions as in the GIF below. How can I do it?
