android-jetpack-compose - 如何检测jetpack compose中的键盘打开和关闭？

Question

我在 compose 中发现的唯一方法是使用 accompanist-insets并删除窗口插入。这会导致我的应用程序布局出现其他问题。
Android方式好像是this我可以将它传递给我的撰写应用程序并采取相应的行动。
Jetpack 组合还有另一种方法吗？

如果你想要声明，我找到了这个解决方案:

enum class Keyboard {
    Opened, Closed
}

@Composable
fun keyboardAsState(): State<Keyboard> {
    val keyboardState = remember { mutableStateOf(Keyboard.Closed) }
    val view = LocalView.current
    DisposableEffect(view) {
        val onGlobalListener = ViewTreeObserver.OnGlobalLayoutListener {
            val rect = Rect()
            view.getWindowVisibleDisplayFrame(rect)
            val screenHeight = view.rootView.height
            val keypadHeight = screenHeight - rect.bottom
            keyboardState.value = if (keypadHeight > screenHeight * 0.15) {
                Keyboard.Opened
            } else {
                Keyboard.Closed
            }
        }
        view.viewTreeObserver.addOnGlobalLayoutListener(onGlobalListener)

        onDispose {
            view.viewTreeObserver.removeOnGlobalLayoutListener(onGlobalListener)
        }
    }

    return keyboardState
}

并检测/检查值，你只需要这个:

val isKeyboardOpen by keyboardAsState() // Keyboard.Opened or Keyboard.Closed
