无法使用滑行创建通知

Question

我正在使用 fcm 接收数据，我想创建一个包含图像的通知。当我得到这个数据时，我得到了我尝试使用 glide 加载的图像的 url，但 glide 拒绝从服务中触发 [FirebaseMessagingService ]

    public class MyFirebaseMessagingService extends FirebaseMessagingService {

private final String TAG = getClass().getName();

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);

    try {

        if (remoteMessage.getData().containsKey("notification")) {

            Gson gson = new Gson();
            Notif notif = gson.fromJson(remoteMessage.getData().get("notification"), Notif.class);

            politicoDataRepository.getPolitico(notif.getPolitico_id())
                    .observeOn(AndroidSchedulers.mainThread())
                    .subscribe(politico -> {

                            createNotifiation(notif, getApplicationContext());

                    }, throwable -> Log.e("Error", throwable.getMessage() + " " + TAG));

        } else {
            Log.i("datFirebase", remoteMessage.getFrom() + "  " + remoteMessage.getData().get("id"));
        }

    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        realm.close();
    }


}

private void createNotifiation(Notif notif, Context context) {

    final RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.notification_item);

    remoteViews.setImageViewResource(R.id.notif_image, R.mipmap.ic_launcher);


    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle(notif.getTitle())
                    .setContentText(notif.getMessage())
                    .setContent(remoteViews)
                    .setPriority(NotificationCompat.PRIORITY_MIN);

    final Notification notification = mBuilder.build();

    if (android.os.Build.VERSION.SDK_INT >= 16) {
        mBuilder.setCustomBigContentView(remoteViews);
    }


    NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(141, notification);


    NotificationTarget notificationTarget = new NotificationTarget(this, remoteViews, R.id.notif_image, notification, 141);

    Glide.with(this)
            .load(notif.getImage())
            .asBitmap()
            .into(notificationTarget);

}

}

Answer 1

尝试使用 NotificationTarget。这是链接Glide — Loading Images into Notifications and AppWidgets

或者你可以这样尝试

remoteViews.setImageViewBitmap(R.id.noti_article_1_imageview, getBitmapFromURL (selectedList[0].getImageUrl()));

remoteViews.setImageViewBitmap(R.id.noti_article_2_imageview, getBitmapFromURL (selectedList1.getImageUrl()));

public Bitmap getBitmapFromURL(String strURL) {
    try {
      URL url = new URL(strURL);
      HttpURLConnection connection = (HttpURLConnection) url.openConnection();
      connection.setDoInput(true);
      connection.connect();
      InputStream input = connection.getInputStream();
      Bitmap myBitmap = BitmapFactory.decodeStream(input);
      return myBitmap;
    } catch (IOException e) {
      e.printStackTrace();
      return null;
    }
  }
