动画expandableListView [英] Animation for expandableListView

问题描述

是否有可能适用的展开或折叠动画expandableListView？

Is it possible to apply an expand or collapse animation for expandableListView?

推荐答案

它可以用一个简单的ListView包含最初隐藏的视图，并扩展动画自定义类来完成。 其基本思路是先从 View.GONE 然后逐渐重新大小的利润率从负值到所需的大小而设置能见度查看。可见。

It can be done using a simple ListView that contains an initially hidden view and a custom class that extends Animation. The basic idea is to start with View.GONE then gradually re-size the margin from a negative value to the required size while setting visibility to View.VISIBLE.

最后一个例子包含了所有你需要的code。它看起来有点hackish对我来说，特别是事实，你必须首先设置 view.bottomMargin = -50 以上，否则动画不会在第一次正常工作，但到目前为止，我没有发现任何可行的替代方案（除了使用滚动型用自己的容器的项目，而不是一个ListView）。

The last example contains all the code you need. It looks a bit hackish to me, especially the fact that you must initially set view.bottomMargin = -50 or more, otherwise the animation does not work properly the first time, but so far I did not find any viable alternative (apart from using a ScrollView with your own container items instead of a ListView).
