有没有办法以编程方式单击文本字段,所以当我的搜索屏幕弹出时,它会自动单击文本字段并弹出键盘。或者,有没有办法知道文本字段的触摸事件?

您可以将焦点放在组件上。
就像是:
var text by remember { mutableStateOf(TextFieldValue("text")) }
val focusRequester = FocusRequester()
val keyboardController = LocalSoftwareKeyboardController.current
val interactionSource = remember { MutableInteractionSource() }
val isFocused by interactionSource.collectIsFocusedAsState()
Column {
TextField(
value = text,
onValueChange = {
text = it
},
interactionSource = interactionSource,
label = { Text("label") },
modifier = Modifier
// add focusRequester modifier
.focusRequester(focusRequester)
.onFocusChanged {
if (isFocused) {
keyboardController?.show()
}
}
)
}
接着:
DisposableEffect(Unit) {
focusRequester.requestFocus()
onDispose { }
}
