我有一个 AlertDialog，我已将其设置为获取所有垂直 space。问题是当键盘出现时，当 AlertDialog 调整大小以适应键盘上方时，我得到一个讨厌的动画。有什么办法可以防止这种情况发生吗？理想情况下，它应该在 AlertDialog 显示之前测量键盘上方的可用 space。

没有针对您的问题的“默认”解决方法。你的 Dialog 首先出现，然后 EditText 被绘制，它请求焦点然后键盘显示 - Dialog 已经被绘制（全屏），所以它缩小
也许你可以尝试在 Dialog 出现之前强制显示键盘
((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)).
toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
然后显示您的 Dialog（可能会有几毫秒的延迟？）并调用 editText.requestFocus() 将键盘“连接”到新显示的 EditText（会有变化自动完成，因为 EditText 可能会在膨胀时请求焦点）
我能够通过仅在用户开始键入时扩展 AlertDialog 的高度来以令人满意的方式解决此问题。在此处观看视频：https://streamable.com/oj3fbv
