Android IME keyboards not working with DatePicker/RangePicker due to keydown handling

[jfernandezpe]

Hi there,

I'm using Antd Date Picker and Range Picker, and I'm facing an issue: I can't use virtual keyboards (Input Method Editors or IMEs) on my Android device because the browser is not passing the actual pressed key to JavaScript. If you listen to the native HTML keydown event, the event.key is Unidentified.

This article describes a similar issue quite well: https://weiyen.net/articles/an-unusual-google-keyboard-bug/. However, I've been researching a bit more and it seems to be related to several virtual keyboards, including GBoard and Microsoft SwiftKey.

I found some issues in Chromium, but unfortunately, it looks like they don't plan to fix this, since it rely on how virtual keyboards work for getting that info:

• https://issues.chromium.org/issues/40539270
• https://issues.chromium.org/issues/41402349

A possible workaround seems to be handling validation and formatting by listening to the input event instead of keydown. So the problem might be in the function onFormatKeyDown, which could still handle special keys like Enter, Escape, etc., and move validation and committing changes to a new input handler.

What do you think about it?

Best regards,
Jose
