Я хочу скрыть кнопку нижнего колонтитула (activity_sign_up. xml), когда editText (frag_sign_up_email_password) имеет фокус.

Я хочу, чтобы нижняя кнопка исчезла в то же время, когда отображается программная клавиатура.

Answer 1

Вы можете использовать onGlobalLayoutListener, чтобы узнать, когда отображается клавиатура.

 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
     }
}

Answer 2

Спасибо, @Gal Machluf Я попробовал ваш метод, но после показа программной клавиатуры нижняя кнопка исчезает. Что мне делать?

[KeyboardVisibilityUtils.kt]

private val onGlobalLayoutListener = ViewTreeObserver.OnGlobalLayoutListener {

    window.decorView.getWindowVisibleDisplayFrame(windowVisibleDisplayFrame)

    val visibleDecorViewHeight = windowVisibleDisplayFrame.height()
    Log.d("debugTest", "visibleDecorViewHeight : $visibleDecorViewHeight")

    if (lastVisibleDecorViewHeight != 0) {

        if (lastVisibleDecorViewHeight > visibleDecorViewHeight + MIN_KEYBOARD_HEIGHT_PX) {

            val currentKeyboardHeight = window.decorView.height - windowVisibleDisplayFrame.bottom
            Log.d("debugTest","decorView height : ${window.decorView.height}, 현재보여지고 있는 크기의 가장 아래 : ${windowVisibleDisplayFrame.bottom}")

            onShowKeyboard?.invoke(currentKeyboardHeight)
        } else if (lastVisibleDecorViewHeight + MIN_KEYBOARD_HEIGHT_PX < visibleDecorViewHeight) {

            onHideKeyboard?.invoke()
        }
    }

    lastVisibleDecorViewHeight = visibleDecorViewHeight
