当我单击对话片段中的文本字段撰写时，手机键盘没有弹出

Question

下面是自定义TextField的代码。我在Fragment和DialogFragment中使用了TextField。我有一些问题，而使用它在DialogFragment。当我在Fragment中使用时，点击下面的TextField，电话键盘打开。但是，即使它专注于TextField，当它在DialogFragment中使用时，键盘也不会弹出。

fun MyTextFiled(
search: (String) -> Unit,
query: String?
) {
var state by rememberSaveable { mutableStateOf(query) }
Card(
shape = RoundedCornerShape(dimensionResource(id = R.dimen.padding_5dp)),
) {
Row(
horizontalArrangement = Arrangement.Center,
verticalAlignment = Alignment.CenterVertically,
modifier = Modifier.height(36.dp).background(colorResource(id = R.color.background_wallet_searchView)),
) {
Icon(
painter = painterResource(id = R.drawable.ic_new_search),
contentDescription = null,
modifier = Modifier
.size(20.dp)
.padding(start = dimensionResource(id = R.dimen.padding_5dp)),
tint = colorResource(id = R.color.text_secondary),
)
BasicTextField(
value = state?:"",
onValueChange = {
search.invoke(it)
state = it
},
maxLines = 1,
modifier = Modifier
.weight(1F)
.align(Alignment.CenterVertically)
.padding(horizontal = dimensionResource(id = R.dimen.padding_5dp)),
singleLine = true,
textStyle = TextStyle(
color = colorResource(id = R.color.text_secondary),
fontSize = 13.sp,
fontStyle = MaterialTheme.typography.overline.fontStyle
),
keyboardOptions = KeyboardOptions.Default.copy(
capitalization = KeyboardCapitalization.Sentences,
autoCorrect = true,
keyboardType = KeyboardType.Number,
imeAction = ImeAction.Search
),
decorationBox = { innerTextField ->
if (state.isNullOrEmpty()) {
Text(
text = stringResource(id = R.string.search),
style = MaterialTheme.typography.overline,
fontSize = 12.sp,
color = colorResource(id = R.color.text_secondary)
)
}
innerTextField()
}
)
if (!state.isNullOrEmpty())
Icon(
painter = painterResource(id = R.drawable.round_close_24),
contentDescription = null,
modifier = Modifier
.clickable {
state = ""
search.invoke("")
}
.size(20.dp)
.padding(end = dimensionResource(id = R.dimen.padding_5dp))
)
}
}
}

MessageScreen:

@Composable
fun MessageScreen(
messagesViewModel: MessagesViewModel,
navHostController: NavController,
sharedViewModel: SharedViewModel
) {
val listState = rememberLazyListState()
// Set State of Message Screen
val receiverProfile = sharedViewModel.receiverProfile
val senderProfile = sharedViewModel.senderProfile
Log.d("TAG", "MessageScreen: RECEIVER = $receiverProfile  SENDER = $senderProfile")
// Get All Messages from Firebase
messagesViewModel.getAllMessageFromFirebase(receiverProfile, senderProfile)
Column(
modifier = Modifier.fillMaxSize(),
verticalArrangement = Arrangement.SpaceBetween,
) {
TopBar(
title = receiverProfile!!.displayName,
buttonIcon = painterResource(id = R.drawable.ic_back_arrow_back_24)
) {
navHostController.popBackStack()
}
Box(modifier = Modifier.weight(10f)) {
LazyColumn(
modifier = Modifier
.fillMaxWidth(),
verticalArrangement = Arrangement.Top,
state = listState
) {
items(items = messagesViewModel.allMessagesState) { message ->
MessageCard(message = message, sharedViewModel = sharedViewModel)
Log.d("TAG 14", message.toString())
}
CoroutineScope(Dispatchers.Main).launch {
if (messagesViewModel.allMessagesState.isNotEmpty()) {
listState.scrollToItem(messagesViewModel.allMessagesState.size - 1)
}
}
}
}
Box(
modifier = Modifier
.fillMaxWidth()
.padding(8.dp), contentAlignment = Alignment.Center
) {
SendMessageCard(messagesViewModel, sharedViewModel)
}
}
}
`
**SendMessageCard :-**
@Composable
fun SendMessageCard(messagesViewModel: MessagesViewModel, sharedViewModel: SharedViewModel) {
Card(
modifier = Modifier
.fillMaxWidth()
.wrapContentHeight(),
elevation = 8.dp
) {
Row(
modifier = Modifier,
horizontalArrangement = Arrangement.SpaceAround
) {
OutlinedTextField(
value = messagesViewModel.textState.value,
onValueChange = {
messagesViewModel.textState.value = it
},
modifier = Modifier.fillMaxWidth(),
keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Text),
trailingIcon = {
IconButton(onClick = {
messagesViewModel.sendMessage(
message = Message(
messagesViewModel.textState.value,
Timestamp.now(),
sharedViewModel.senderProfile!!.mailId
),
sharedViewModel = sharedViewModel
)
}) {
Icon(imageVector = Icons.Filled.Send, contentDescription = "Send Message")
}
},
textStyle = TextStyle(fontSize = 20.sp),
label = {
Text(text = "Type Message")
}
)
}
}
}

我找到了解决问题的方法。我在Dialog Fragment中使用了Dialog Compose，然后弹出了键盘。
