【问题描述】：

据我了解，Jetpack Compose Textfield 有一个 API 用于捕获键盘操作，但我不知道哪些 API 可以捕获 Enter-Input

此捕获输入输入的用例是启用单击 Enter 并尝试转到下一个 TextField 并在保持键盘打开的同时保持

OutlinedTextField(
    value = username.value,
    onValueChange = 
        username.value = it
        ,
    keyboardActions = KeyboardActions(
        onDone = ,
        onGo = ,
        onNext = ,
        onPrevious =,
        onSearch =,
        onSend = 
        )
)

【参考方案1】：

你可以使用类似的东西：

val (focusRequester) = FocusRequester.createRefs()

TextField(
    value = text,
    onValueChange = 
        text = it
    ,
    singleLine = true,
    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
    keyboardActions = KeyboardActions(
        onDone =  focusRequester.requestFocus() 
    ),
    modifier = Modifier.onKeyEvent 
        if (it.nativeKeyEvent.keyCode == KeyEvent.KEYCODE_ENTER)
            focusRequester.requestFocus()
            true
        
        false
    
)

TextField(
    value = text2,
    onValueChange = 
        text2 = it
    ,
    modifier = Modifier.focusRequester(focusRequester),
)

【讨论】：

感谢您，我尝试将其添加到第二个文本字段 singleLine = true, keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done), keyboardActions = KeyboardActions( onDone = focusRequester.requestFocus() ), modifier = Modifier.onKeyEvent if (it.nativeKeyEvent.keyCode == KeyEvent.KEYCODE_ENTER) focusRequester.requestFocus() true false 到第二个文本字段并改用 focusRequester.freeFocus() 但不知何故它并没有消除对第二个文本字段的关注任何想法关于这个？

@ArcRuler 使用val focusManager = LocalFocusManager.current 并在第二个字段的Modifier.onKeyEvent 中：focusManager.clearFocus()
