我有一个lazyColumn,我想在列中使用它,但出现以下错误并且应用程序崩溃:
Nesting scrollable in the same direction layouts like LazyColumn and Column(Modifier.verticalScroll()) is not allowed. If you want to add a header before the list of items please take a look on LazyColumn component which has a DSL api which allows to first add a header via item() function and then the list of items via items()
lazyColumn 代码,我在这段代码中有一个列表:
@Composable
fun UpScreenSection(
modifier: Modifier,
state: ProfileState,
viewModel: ProfileViewModel
) {
Spacer(modifier = Modifier.size(24.dp))
Column(
modifier = modifier
.fillMaxSize()
.padding(24.dp)
) {
if (!state.items.isNullOrEmpty()) {
Box(
modifier = modifier
.fillMaxSize()
) {
LazyColumn(modifier = modifier.fillMaxSize()) {
items(state.items) { item ->
ProfileListItems(item = item, onItemClick = {
//TODO Navigate to specific screen
when (it.id) {
1 -> {
}
2 -> {
}
3 -> {
}
4 -> viewModel.navigate(ReferAFriendDestination.route())
}
})
}
}
}
}
}
Spacer(modifier = Modifier.size(24.dp))
}
以下可组合代码中使用的上述代码:
@Composable
fun ProfileContentSection(
modifier: Modifier = Modifier,
viewModel: ProfileViewModel
) {
val context = LocalContext.current
val scrollState = rememberScrollState()
Box(
modifier = modifier
.fillMaxSize()
) {
val state = viewModel.state.value
Column(
modifier = modifier
.fillMaxSize()
.verticalScroll(state = scrollState)
) {
AccountNameSection(modifier = modifier, viewModel = viewModel)
UpScreenSection(modifier, state, viewModel) // used above block codes
DownScreenSection(modifier, context)
}
if (state.error.isNotBlank())
SimpleSnackbar(
text = state.error,
modifier = modifier.align(Alignment.BottomCenter)
)
if (state.isLoading)
Loading(modifier = modifier.align(Alignment.BottomCenter))
}
}
我该如何解决这个错误?
注意:我想要一个可滚动的屏幕,其中包含小型设备的列表
