android - 使用 ImageLoader 显示带有外部图像链接的通知

Question

我正在尝试使用 ImageLoader 显示带有外部图像链接的通知，但没有任何运气。 Logcat 不显示任何错误，也根本不显示通知。

这是我的代码:

void shownot()
{
    mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
Intent intent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
    .setLargeIcon(getSingleItemLargeIcon(IMAGE_LINK_URL))
    .setTicker("test test test test test test")
    .setContentTitle("test test test test test test")
    .setAutoCancel(true)
    .setContentText("test test test test test test");

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(1, mBuilder.build());
}



private Bitmap getSingleItemLargeIcon(String imageUri) {
    ImageLoader imageLoader = ImageLoader.getInstance();
    imageLoader.init(config);

    imageLoader.loadImage(imageUri, new ImageLoadingListener() {

    @Override
    public void onLoadingStarted(String arg0, View arg1) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onLoadingFailed(String arg0, View arg1, FailReason arg2) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onLoadingComplete(String arg0, View arg1, Bitmap arg2) {
        bitmap = arg2;
    }

    @Override
    public void onLoadingCancelled(String arg0, View arg1) {
        // TODO Auto-generated method stub

    }
});

return bitmap;
}

我错过了什么吗？

终于明白了。似乎您需要在通知中设置 setSmallIcon() 以显示通知:

void shownot() {
    NotificationManager mNotificationManager = (NotificationManager) this
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Intent intent = new Intent(this, PhotoIntentActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            intent, 0);
    Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
            R.drawable.microphone);// download this bitmap from internet
    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
            this).setLargeIcon(bitmap).setSmallIcon(R.drawable.icon)
            // this is also required
            .setTicker("+1 notification").setContentTitle("Awsome Title")
            .setAutoCancel(true).setContentText("Awsome Text");

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(1, mBuilder.build());
}
