Android:OneSignal如何使用自定义图标或应用图标更改通知帐单图标？

Question

收到通知后,会显示帐单图标而不是应用图标或自定义图标,我会覆盖它以显示代码.我可以从仪表板更改图标,但我想从代码中处理它

Intilaization

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

接收器类

  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");

}

Answer 1

您需要ic_stat_onesignal_default在drawables目录中创建一个名称,而不是OneSignal的默认铃声图标.建议您使用Android Asset Studio创建正确的尺寸,并确保它在您的设备上尝试之前看起来正确.

请注意,应用图标不应再用作Android 5.0 Lollipop中的小型通知图标,只会使用图标的alpha.在这种情况下,大多数应用程序图标只是一个白色的乡绅或圈子.

有关详细信息,请参阅下面的OneSignal文档页面. https://documentation.onesignal.com/docs/customize-notification-icons

Answer 2

您必须为以下尺寸创建图标：

drawable-hdpi/ic_stat_one_signal_default.png

drawable-mdpi/ic_stat_one_signal_default.png

drawable-xhdpi/ic_stat_one_signal_default.png

drawable-xxhdpi/ic_stat_one_signal_default.png

drawable-xxxhdpi/ic_onesignal_large_icon_default.png

请注意，大小drawable-xxxhdpi的名称不同。

我建议使用Android Asset Studio或从Android Studio-> app-> Image Asset创建图标，以确保具有适用于不同Android版本的图标。

如果要具有两个图标类型，一个用于通知区域，一个用于通知抽屉，则必须执行以下操作：

1.-创建不同大小相同的图像图标：mdpi，hdpi，xhdpi，xxhpi叫做：ic_stat_one_signal_default

2.-创建另一个图像图标，其大小xxxhdpi称为：ic_onesignal_large_icon_default

看起来像： 图标-通知区域/抽屉
