我正在寻找一种使用Picasso加载通知图标(这是远程网页上的URL)的简便方法。在该应用程序的早期版本中,我正在处理此代码似乎可以正常工作:

        Bitmap speakerPic = null;
        try {
            speakerPic = new AsyncTask<Void, Void, Bitmap>() {
                @Override
                protected Bitmap doInBackground(Void... params) {
                    try {
                        return Picasso.with(c).load(session.getSpeaker().getPhotoUrl()).get();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                    return null;
                }
            }.execute().get(1500, TimeUnit.MILLISECONDS);
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        } catch (TimeoutException e) {
            e.printStackTrace();
        }

        if (speakerPic != null) {
            builder.setLargeIcon(speakerPic);
        } else {
            builder.setLargeIcon(BitmapFactory.decodeResource(c.getResources(), R.drawable.ic_launcher));
        }

但是现在我每次都收到一个TimeOutException(并且我退回到res文件夹中的默认图标)。我必须使用此AsyncTask,因为UI线程上可能不会出现 picasso (/network)。 (尽管我在这里将UI线程阻塞了1.5秒。)。

我知道 picasso 可以处理远程 View ,但是我不想使用自定义 View 进行通知。我也找不到一种方法来获取NoticifationIcon的RemoteView。

有没有一种方法可以仅使用Picasso设置我的通知图标?

最佳答案

我会自己回答问题,因为我找到了使用Picasso和RemoteViews的不错方法。经过测试并与Picasso 2.5.2配合使用:

// Default stuff; making and showing notification
final Context context = getApplicationContext();
final NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
final Notification notification = new NotificationCompat.Builder(context)
        .setSmallIcon(R.mipmap.ic_launcher) // Needed for the notification to work/show!!
        .setContentTitle("Title of notification")
        .setContentText("This is the description of the notification")
        // Uncomment if you want to load a big picture
        //.setStyle(new NotificationCompat.BigPictureStyle())
        .build();
final int notifId = 1337;
notificationManager.notify(notifId, notification);

// Get RemoteView and id's needed
final RemoteViews contentView = notification.contentView;
final int iconId = android.R.id.icon;

// Uncomment for BigPictureStyle, Requires API 16!
//final RemoteViews bigContentView = notification.bigContentView;
//final int bigIconId = getResources().getIdentifier("android:id/big_picture", null, null);

// Use Picasso with RemoteViews to load image into a notification
Picasso.with(getApplicationContext()).load("http://i.stack.imgur.com/CE5lz.png").into(contentView, iconId, notifId, notification);

// Uncomment for BigPictureStyle
//Picasso.with(getApplicationContext()).load("http://i.stack.imgur.com/CE5lz.png").into(bigContentView, iconId, notifId, notification);
//Picasso.with(getApplicationContext()).load("http://i.stack.imgur.com/CE5lz.png").into(bigContentView, bigIconId, notifId, notification);
