描述
Description
When switching between different keyboard types on Android, Keyboard.addListener events and Keyboard.metrics()?.height return the height of the previous keyboard instead of the current one. This issue occurs consistently when the previous and current keyboards have different heights (e.g., switching from numeric keyboard to password keyboard, or from system security keyboard to regular keyboard). The problem affects both event callback heights and the static Keyboard.metrics()?.height value. The issue resolves itself on the next keyboard opening, but can be stably reproduced by switching between different keyboard types.
Steps to reproduce
Steps to reproduce the behavior:
- Open an app with text inputs on Android device
- Focus on a text input with
keyboardType: 'numeric' - Note the keyboard height (e.g., 300px)
- Switch to another text input with
keyboardType: 'visible-password' - Observe that both
Keyboard.addListenerevents andKeyboard.metrics()?.heightreturn the previous keyboard's height (300px) instead of the current keyboard's height - Close and reopen the keyboard - the issue resolves and correct height is returned

调研方向
首先,在 Android 上使用键盘类型为 numeric 和 visible-password 的输入来复现问题,然后检查 Keyboard.addListener 和 Keyboard.metrics() 背后的实现。验证切换键盘以及重新打开键盘时报告的高度;当事件回调和 metrics 都报告当前键盘高度时,即表示完成。
