Recently, I have come across a question: how to reduce animita ExpandableListViewdown and up. I am looking for a result in StackOverflow. There is the answer: Android animate the dropdown menu / up correctly
But it is suitable for ListView. When I use it on ExpandableListView, it does not work. I think there must be someone who can solve this similar problem. If you have free time, you can tell me a solution or give advice on this.
