在 Jetpack Compose 中添加 AlertDialog 时获取 "Can't find ColorStateList from drawable resource ID"

Question

我在我的应用程序中添加 AlertDialog 时遇到此 Can't find ColorStateList from drawable resource ID #0x108028b 错误。

我也尝试关注 this answer，但没有用。如果 android:statusBarColor 是问题，那么这是我在 night\themes.xml

中使用的代码

<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <style name="Theme.AppName" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
        <!-- Primary brand color. -->
        <item name="colorPrimary">@color/purple_200</item>
        <item name="colorPrimaryVariant">@color/purple_700</item>
        <item name="colorOnPrimary">@color/black</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/teal_200</item>
        <item name="colorSecondaryVariant">@color/teal_200</item>
        <item name="colorOnSecondary">@color/black</item>
        <!-- Status bar color. -->
<!--        <item name="statusBarBackground">@color/statusBarDark</item>-->
        <item name="android:statusBarColor">?android:attr/colorBackground</item>
        <!-- Navigation bar color. -->
        <item name="android:navigationBarColor">?android:attr/windowBackground</item>
        <!-- Customize your theme here. -->
    </style>

    <style name="ThemeOverlay.AppName.FullscreenContainer" parent="">
        <item name="fullscreenBackgroundColor">@color/light_blue_900</item>
        <item name="fullscreenTextColor">@color/light_blue_A400</item>
    </style>
</resources>

编写代码：

@Composable
fun AlertDialogSample() {
    MaterialTheme {
        Column {
            val openDialog = remember { mutableStateOf(false)  }

            Button(onClick = {
                openDialog.value = true
            }) {
                Text("Click me")
            }

            if (openDialog.value) {
                AlertDialog(
                    onDismissRequest = {
                        openDialog.value = false
                    },
                    title = {
                        Text(text = "Dialog Title")
                    },
                    text = {
                        Text("Here is a text ")
                    },
                    confirmButton = {
                        Button(
                            onClick = {
                                openDialog.value = false
                            }) {
                            Text("This is the Confirm Button")
                        }
                    },
                    dismissButton = {
                        Button(
                            onClick = {
                                openDialog.value = false
                            }) {
                            Text("This is the dismiss Button")
                        }
                    }
                )
            }
        }
    }
}

我不确定到底是什么导致了这个问题，需要一些帮助来解决这个问题。谢谢。

解决了。

问题出在下一行，不知道为什么 ?android:attr/windowBackground 不起作用，但改为简单的 @color/yourColor 就解决了。

<item name="android:navigationBarColor">?android:attr/windowBackground</item>
