How to load Glide cached image in NotificationCompat.Builder.setLargeIcon()?

问题

Like this image I am trying to set notification large icon as user profile thumbnail like whatsapp or other chatting apps

I have tried

 Glide.with(context)
            .asBitmap()
            .load(messageNotification.getLargeIcon())
            .into(new SimpleTarget<Bitmap>() {
                @Override
                public void onResourceReady(Bitmap resource, Transition<? super Bitmap> transition) {
                   builder.setLargeIcon(resource);

                }
            });

but it is not working.. Any Help?

回答1:

If you set the large icon using glide..the you should also notify the NotificationManager onResourceReady(resource, transition)

.into(new SimpleTarget<Bitmap>() {
    @Override
    public void onResourceReady(Bitmap res, Transition<? super Bitmap> t) {
       builder.setLargeIcon(res);
       yourNotificationManager.notify(id, builder.build());

    }
});

This is because glide uses background thread to load image..so before your image is loaded into builder... the notification manager is already notified (mainthread) with builder not having large image..
