推荐答案

有这样做的几种选择。最简单的可能就是使用 ViewPropertyAnimator ，例如

There are several alternatives for doing this. The simplest one is probably to use a ViewPropertyAnimator, e.g.

view.animate().translationY(value);

要获取的当前值（例如，如果你想用一个固定偏移更新它），你可以使用的 view.getTranslationY（） 。

To get the current value (for example if you want to update it with a fixed offset) you can use view.getTranslationY().
