如何解决显示键盘时，全屏 AlertDialog 出现卡顿动画
在此处观看视频以了解问题：https://streamable.com/s0yhrm
或者在更快的设备上查看：https://streamable.com/4sshdn
我设置了一个 AlertDialog 来占据所有垂直空间。问题是当键盘出现时，随着 AlertDialog 调整大小以适应键盘上方，我会得到一个令人讨厌的动画。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空间。

解决方法
您的问题没有“默认”解决方法。您的 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），所以它缩小了
也许您可以尝试在 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() 以“连接”键盘到新显示的 EditText（有一个更改将自动完成，因为 EditText 在膨胀时可能会请求焦点）
仅当用户开始输入时，我才能够通过扩展 AlertDialog 的高度以令人满意的方式解决此问题。在此处观看视频：https://streamable.com/oj3fbv
