Jetpack Compose でキーボードを閉じる方法

Posted at

LocalSoftwareKeyboardController.current.hide() を呼ぶことでキーボードを閉じることができる。

@OptIn(ExperimentalComposeUiApi::class)
@Composable
fun Greeting() {
  val keyboardController = LocalSoftwareKeyboardController.current
  var text by remember { mutableStateOf("") }
  TextField(
    value = text,
    onValueChange = { text = it },
    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
    keyboardActions = KeyboardActions(onDone = {
      keyboardController?.hide()
    }),
  )
}

LocalSoftwareKeyboardController は実験的機能であるため、コンパイルエラーを回避するために @OptIn(ExperimentalComposeUiApi::class) を付ける必要がある。
