我正在学习Android Jetpack Compose中的文本字段，在一个屏幕中有两个文本字段。当我在第一个文本字段中输入内容时，希望在屏幕上点击空白处时关闭键盘。我尝试使用
.pointerInput(Unit) {
detectTapGestures(onTap = {
focusManager.clearFocus()
})
}
这段代码适用于单个文本框，它能够正常工作。但是当使用多达10个文本框时，比如我点击第8个文本框，底部屏幕会变黑。我不知道为什么会这样，你有什么想法吗？
@Composable
fun KeyboardSample(){
val focusManager = LocalFocusManager.current
Column(
modifier = Modifier
.fillMaxSize()
.pointerInput(Unit) {
detectTapGestures(onTap = {
focusManager.clearFocus()
})
}
.padding(start = 16.dp, end = 16.dp),
) {
var name by rememberSaveable { mutableStateOf("") }
val updateName = { _name : String ->
name = _name
}
var amount by rememberSaveable { mutableStateOf("") }
val updateAmount = { _amount : String ->
amount = _amount
}
TextFiledsToExperiment(
name = name,
updateName = updateName,
amount = amount,
updateAmount = updateAmount
)
}
}
@Composable
fun TextFiledsToExperiment(
name : String,
updateName : (String) -> Unit,
amount : String,
updateAmount : (String) -> Unit
){
val focusManager = LocalFocusManager.current
Column(
horizontalAlignment = Alignment.CenterHorizontally,
verticalArrangement = Arrangement.Center
) {
OutlinedTextField(
value = name,
onValueChange = updateName ,
label = { Text("Name") },
placeholder = { Text(text = "Name") },
singleLine = true,
keyboardOptions = KeyboardOptions.Default.copy(
capitalization = KeyboardCapitalization.Sentences,
autoCorrect = true,
keyboardType = KeyboardType.Text,
imeAction = ImeAction.Next
),
keyboardActions = KeyboardActions(onNext = {
focusManager.moveFocus(FocusDirection.Down)
}),
modifier = Modifier
.fillMaxWidth()
.padding(top = 6.dp, start = 0.dp, end = 0.dp, bottom = 6.dp),
)
OutlinedTextField(
value = amount,
onValueChange = updateAmount ,
label = { Text("Amount") },
placeholder = { Text(text = "Amount") },
singleLine = true,
keyboardOptions = KeyboardOptions.Default.copy(
capitalization = KeyboardCapitalization.Sentences,
autoCorrect = true,
keyboardType = KeyboardType.Number,
imeAction = ImeAction.Done
),
keyboardActions = KeyboardActions(onDone = {
focusManager.clearFocus()
}),
modifier = Modifier
.fillMaxWidth()
.padding(top = 6.dp, start = 0.dp, end = 0.dp, bottom = 6.dp),
