我想隐藏页脚按钮（activity_sign_up.xml）editText（fragment_sign_up_email_password）具有焦点。
我想让底部按钮在显示软键盘的同时消失。
您可以使用onGlobalLayoutListener知道何时显示键盘。
view?.viewTreeObserver?.addOnGlobalLayoutListener {
val rect = Rect()
view?.getWindowVisibleDisplayFrame(rect)
val screenHeight = view?.rootView?.height
val keypadHeight = screenHeight?.minus(rect.bottom) ?: return
if (keypadHeight > screenHeight * KEYBOARD_MINIMUM_HEIGHT_PERCENTAGE) {
//keyboard is shown do what ever you like
} else {
//keyboard is hidden
}
}
