Jetpack组合:无法更改TextField焦点
Jetpack组合:无法更改TextField焦点
提问于 2022-09-16 18:19:52
所以，我有一个AlertDialog，里面有一个ListItem，而在里面又有两个TextField：
val keyboardController = LocalSoftwareKeyboardController.current
val focusManager = LocalFocusManager.current
val (nameFieldFocus, valueFieldFocus) = remember{FocusRequester.createRefs()}
AlertDialog(
...
text = {
ListItem(
...
leadingContent = {
Column(verticalArrangement = Arrangement.spacedBy(10.dp)) {
TextField(
modifier = Modifier.focusRequester(nameFieldFocus).focusProperties{next = valueFieldFocus}.focusable(),
value = someValue,
onValueChange = {someValue = it},
label = {Text(text = "Some label")},
keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next),
keyboardActions = KeyboardActions(onNext = {focusManager.moveFocus(FocusDirection.Next)}),
singleLine = true
)
TextField(
modifier = Modifier.focusRequester(valueFieldFocus).focusProperties{previous = nameFieldFocus}.focusable(),
value = anotherValue,
onValueChange = {anotherValue = it},
label = {Text(text = "Another label")},
keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Number),
keyboardActions = KeyboardActions(onDone = {focusManager.clearFocus()}),
singleLine = true
)
}
}
)
}
)问题是，当我按下键盘上的操作键时，无论文本字段中是否包含文本，都不会发生焦点更改。我还尝试了onNext = null和onDone = null，它们应该根据文档使用默认实现，但这也不像预期的那样。
使用androidx.compose.material3.的P.S.

您应该在val focusManager = LocalFocusManager.current内部调用AlertDialog。另外，移除Modifier.focusable()。
AlertDialog(
text = {
val focusManager = LocalFocusManager.current
val (nameFieldFocus, valueFieldFocus) = remember { FocusRequester.createRefs() }
ListItem(
leadingContent = {
Column(verticalArrangement = Arrangement.spacedBy(10.dp)) {
TextField(
modifier = Modifier
.focusRequester(nameFieldFocus)
.focusProperties { next = valueFieldFocus },
value = someValue,
onValueChange = { someValue = it },
label = { Text(text = "Some label") },
keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next),
keyboardActions = KeyboardActions(onNext = {
focusManager.moveFocus(
FocusDirection.Next
)
}),
singleLine = true
)
TextField(
modifier = Modifier
.focusRequester(valueFieldFocus)
.focusProperties { previous = nameFieldFocus },
value = anotherValue,
onValueChange = { anotherValue = it },
label = { Text(text = "Another label") },
keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Number),
keyboardActions = KeyboardActions(onDone = { focusManager.clearFocus() }),
singleLine = true
)
}
},
headlineText = {
Text(text = "Headline Text")
}
)
},
confirmButton = {
Button(onClick = { /*TODO*/ }) {
Text(text = "Confirm")
}
},
onDismissRequest = {
}
