Question

我正在创建一个消息传递应用程序，因此通知在我的应用程序中起着重要的作用。我已经创建了通知显示处理程序，通知在一台，Motorola，Samsung上正常运行，但在Mi设备上却没有。默认情况下，我的应用程序在MI设备（MIUI10）中禁用锁屏通知。但是，当我检查了诸如WhatsApp，Snapchat之类的流行应用程序的设置时，所有选项都已启用，例如锁屏通知，声音，浮动通知。

我可以手动启用所有设置，但我想以编程方式进行设置，因此用户不需要这样做。我尝试使用其方法setLockscreenVisibility()使用通知通道（适用于上述O设备），但此方法不起作用。

notificationChannel = new NotificationChannel(ChatSDKMessageChannel, name, NotificationManager.IMPORTANCE_HIGH);
notificationChannel.setSound(soundUri, audioAttributes);
channel.enableVibration(true);

/// 显示通知的代码

public void createAlertNotification（上下文上下文，Intent resultIntent，String标题，String消息，位图largeIcon，int smallIconResID，Uri soundUri，int编号）{

    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, resultIntent, PendingIntent.FLAG_CANCEL_CURRENT);

    Notification.Builder builder =
            new Notification.Builder(context)
                    .setContentTitle(title)
                    .setContentText(message)
                    .setSmallIcon(smallIconResID)
                    .setVibrate(new long[]{0, 250, 100, 250})
                    .setSound(soundUri)
                    .setNumber(number)
                    .setContentIntent(pendingIntent)
                    .setTicker(title + ": " + message)
                    .setPriority(Notification.PRIORITY_HIGH);

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    if (largeIcon != null) {
        builder.setLargeIcon(ImageUtils.scaleImage(largeIcon, (int) (context.getResources().getDisplayMetrics().density * 48)));
    }

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        builder.setColor(ChatSDK.config().pushNotificationColor);
    }

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        // Create the NotificationChannel, but only on API 26+ because
        // the NotificationChannel class is new and not in the support library
        builder.setChannelId(ChatSDKMessageChannel);

        CharSequence name = context.getString(R.string.app_name);
        String description = context.getString(R.string.push_channel_name);

        NotificationChannel channel = new NotificationChannel(ChatSDKMessageChannel, name, NotificationManager.IMPORTANCE_HIGH);
        channel.enableVibration(true);
        channel.setDescription(description);

        if (notificationManager != null) {
            notificationManager.createNotificationChannel(channel);
        }

    }


    Notification notification = builder.build();

    notification.flags = Notification.FLAG_AUTO_CANCEL ;

    notificationManager.notify(MESSAGE_NOTIFICATION_ID, notification);

    wakeScreen(context);
}

我需要为我的应用程序启用所有通知选项，就像WhatsApp和snapchat。

也许您需要权限验证

有什么方法可以以编程方式在MIUI 10上启用锁定屏幕通知吗？
