当我修改列表中对象的属性时，UI不会更新
我的代码是:
@OptIn(ExperimentalFoundationApi::class)
@Composable
fun ContactCard(
) {
var stateList = remember {
mutableStateListOf<ListViewData>()
}
viewModel!!.recordRespListLiveData!!.observe(this) { it ->
it.forEach {
stateList.add(ListViewData(false, it))
}
}
LazyColumn() {
stateList.forEachIndexed { index, bean ->
stickyHeader() {
Box(Modifier.clickable {
stateList[index].visible = true
}) {
ContactNameCard(bean.data.contact, index)
}
}
items(bean.data.records) { data ->
if (bean.visible) {
RecordItemCard(record = data)
}
}
}
}
}
当我单击该框时，可见设置为真，但RecordItemCard不显示，这是为什么？
