Question

当我在Android 10中将显示模式更改为Dark时，按照此处显示的图像获取Dark（黑色）通知。我尝试更改文本颜色，但未更改。我正在使用远程视图创建自定义通知。如何更改暗模式和亮模式下不同的远程内容视图文本颜色？这是我的代码：

        val contentViewBig = RemoteViews(context.applicationContext.packageName, R.layout.design_custom_notification)
        contentViewBig.setTextViewText(R.id.tvNotificationTitle, notificationTitle)
        contentViewBig.setTextViewText(R.id.tvNotificationBody, notificationBody)

        val nId = Random().nextInt()

        val pendingIntent = PendingIntent.getActivity(context,
                nId /* Request code */, intent, PendingIntent.FLAG_UPDATE_CURRENT)
        val channelId = context.getString(R.string.default_notification_channel_id)
        val defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)

        val notificationBuilder = NotificationCompat.Builder(context, channelId)
                .setSmallIcon(R.drawable.ic_notification)
                .setAutoCancel(true)
                .setCustomContentView(contentViewBig)
                .setPriority(NotificationCompat.PRIORITY_MAX)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setLights(Color.WHITE, 2000, 3000)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent)


        // Since android Oreo notification channel is needed.
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

            val channel = NotificationChannel(channelId,
                    context.resources.getString(R.string.app_name), NotificationManager.IMPORTANCE_HIGH)
            channel.description = context.resources.getString(R.string.app_name)
            channel.setShowBadge(true)
            channel.lockscreenVisibility = Notification.VISIBILITY_PUBLIC
            notificationManager?.createNotificationChannel(channel)
        }

        if (notificationManager != null) {
            notificationManager.notify(nId, notificationBuilder.build())
            wakeLockScreen(context)
        }

我通过创建 values-night 文件夹解决了问题。我在 values-night 文件夹中添加了colors.xml，并覆盖了我在常规 values-colors.xml 中使用的颜色，并在远程视图设计文件中应用了文本颜色。 / p>
