Jetpack Compose中remember与mutableStateOf无法更新Text问题

我在开发一款基于Jetpack Compose的应用，功能是从外部API获取数据并展示图表。目前数据能正常获取，但图表不会随新数据重组。为定位问题，我编写了一个最简的Counter可组合函数进行测试：点击按钮时，count值在Logcat和Toast中能正常增长，但Text组件始终显示0。这段测试代码在其他项目中可以正常运行。

测试代码 #

@Composable
fun Counter() {
    val count = remember { mutableStateOf(0) }
    val context = LocalContext.current
    Column(
        Modifier.fillMaxSize(),
        verticalArrangement = Arrangement.Center,
        horizontalAlignment = Alignment.CenterHorizontally
    ) {

        Button(
            onClick = {
                count.value++
                Log.d("f", "Value: ${count.value}")
                Toast.makeText(context, "Clicked button ${count.value}", Toast.LENGTH_SHORT).show()
            }
        ) {
            Text("Click me")
        }
        Text(text = "Current count: ${count.value}")
    }
}

相关截图说明 #

• 模拟器截图：界面上Text组件始终显示"Current count: 0"，按钮点击后UI无更新
• Logcat截图：每次点击按钮后，日志中输出的count值依次递增（如Value: 1、Value: 2等）
