如何通过仅具有此图片URL的毕加索将图片添加到通知大图标中？

Question

如何将大图标设置为通知？我在timetable.getImage（）中获取图像的URL。在我的项目中，毕加索支持get（）方法，而不支持with（）。我是android新手，请帮忙。您可以在下面的图片中看到我的通知。通知的图标图像已硬编码。但是我需要来自timetable.getImage（）的图标图像。这是我的代码：

公共类EpisodeNotifyActivity扩展了AppCompatActivity {

private NotificationManagerCompat notificationManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.ativity_episode_notify);


    final Timetable timetable = (Timetable) requestService.getResult();
    ImageView serImage = (ImageView) findViewById(R.id.seriesImage1);

    Button button = findViewById(R.id.notify);
    Picasso.get()
            .load(timetable.getImage())
            .into(serImage);    

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            sendNotification(timetable.getSeriesName().toUpperCase() + ", New Episode", timetable.getEpisodesSeason().toString() + "x" + timetable.getEpisodesNumber() + " " + timetable.getEpisodeName());
                      }        });    }  

private void sendNotification(String messageTitle, String messageBody) {
    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    Intent intent = new Intent(this, EpisodeNotifyActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        @SuppressLint("WrongConstant")
        NotificationChannel notificationChannel = new NotificationChannel("my_notification", "n_channel", NotificationManager.IMPORTANCE_MAX);
        notificationChannel.setDescription("description");
        notificationChannel.setName("Channel Name");
        assert notificationManager != null;
        notificationManager.createNotificationChannel(notificationChannel);

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_live_tv_black_24dp)
                .setContentTitle(messageTitle)
             //   .setLargeIcon(R.drawable.icon)
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(soundUri)
                .setContentIntent(pendingIntent)
                .setDefaults(Notification.DEFAULT_ALL)
                .setOnlyAlertOnce(true)
                .setChannelId("my_notification")
                .setColor(Color.parseColor("#3F5996"));
        assert notificationManager != null;
        int m = (int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE);
        notificationManager.notify(m, notificationBuilder.build());
    }    
}}
