简单粗暴法

通过LocalSoftwareKeyboardController.current获取SoftwareKeyboardController对象，对软键盘进行显示与关闭操作

val keyboardController = LocalSoftwareKeyboardController.current

在最外层的组件中通过监听点击事件，执行键盘的关闭操作
此方法存在一定弊端，谨慎使用

Box(
        modifier = Modifier
            .fillMaxSize()
            .clickable {
   
                keyboardController?.hide()
            }
    ){
   
    //your code
    }

常规方法

    val keyboardController = LocalSoftwareKeyboardController.current
    val focusRequester = FocusRequester()
    val focusManager = LocalFocusManager.current

通过pointerInput监听单击点击事件，并清除当前聚焦组件的焦点
在文本编辑框TextField中通过Modifier完成对焦点请求和焦点变化的监听处理

 Box(
        modifier = Modifier
            .fillMaxSize()
            .pointerInput(Unit) {
   
                detectTapGestures(onTap = {
   
                    focusManager.clearFocus()
                })
            }
    ){
   
         TextField(
            value = userTextStatus.text,
            onValueChange = onChangeUser,
            singleLine = true,
            textStyle = TextStyle(color = MagicMusicTheme.colors.textContent, fontSize = 12.sp),//输入框内的字体样式
            label = {
    Text(text = userTextStatus.label, color = MagicMusicTheme.colors.textTitle, style = MaterialTheme.typography.body1)},//上方提示字体样式
            placeholder = {
   Text(text = userTextStatus.hint, color = MagicMusicTheme.colors.textContent, style = MaterialTheme.typography.caption)},//hint的字体样式
            keyboardOptions = KeyboardOptions(
                keyboardType = KeyboardType.Text,
                imeAction = ImeAction.Done
            ),
            keyboardActions = KeyboardActions(onDone = {
   
                focusManager.clearFocus()
            }),
            modifier = Modifier
                .fillMaxWidth()
                .focusRequester(focusRequester)
                .onFocusChanged {
   
                    if (!it.isFocused) {
   
                        keyboardController?.hide()
                    }
                }
        )
    }
