Android:OneSignal 如何使用自定义图标或应用程序图标更改通知账单图标？

Question

当收到通知时，会显示账单图标，而不是应用程序图标或自定义图标，我会覆盖它以从代码中显示。我可以从仪表板更改图标，但我想从代码中处理它

嵌入

    OneSignal.startInit(this)
            .inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification)// to hide dialog
            .setNotificationOpenedHandler(new ExampleNotificationOpenedHandler())
            .init();

接收类

  class ExampleNotificationOpenedHandler implements OneSignal.NotificationOpenedHandler
{
    // This fires when a notification is opened by tapping on it.
    @Override
    public void notificationOpened(OSNotificationOpenResult result)
    {
        OSNotificationAction.ActionType actionType = result.action.type;
        JSONObject data = result.notification.payload.additionalData;
        String customKey;

        Intent intent = new Intent(Roshetta.app, SplashActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);


        int requestCode = 0;

            PendingIntent pendingIntent = PendingIntent.getActivity(Roshetta.app, requestCode, intent, PendingIntent.FLAG_ONE_SHOT);
            Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
            Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);

            android.support.v4.app.NotificationCompat.Builder noBuilder = new android.support.v4.app.NotificationCompat.Builder(Roshetta.app)
                    .setSmallIcon(R.mipmap.ic_launcher).setLargeIcon(largeIcon).setContentTitle(result.notification.payload.title)
                    .setContentText(result.notification.payload.body )
                    .setAutoCancel(true).setDefaults(android.app.Notification.DEFAULT_ALL)
                    .setContentIntent(pendingIntent).setSound(sound);


            NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
             notificationManager.notify(0, noBuilder.build()); //0 = ID of notification


            if (data != null)
            {
                customKey = data.optString("customkey", null);
                if (customKey != null)
                    Log.i("OneSignalExample", "customkey set with value: " + customKey);
            }

            if (actionType == OSNotificationAction.ActionType.ActionTaken)
                Log.i("OneSignalExample", "Button pressed with id: " + result.action.actionID);


            Log.i("OneSignalExample", "ExampleNotificationOpenedHandler");

您需要在 drawables 目录中创建一个名为 ic_stat_onesignal_default 的图标，该图标将代替 OneSignal 的默认铃铛图标显示。建议使用 Android Asset Studio创建正确的尺寸并确保它在您的设备上试用之前看起来正确。

请注意，应用程序图标不应再用作小通知图标，因为在 Android 5.0 Lollipop 中只会使用图标的 alpha。在这种情况下，大多数应用程序图标将只是一个白色的乡绅或圆圈。
