我正在尝试 .setLargeIcon(getBitmapFromUrl(url) 但它没有设置。
public void showSmallNotification(String title, String message, String url, Intent intent) {
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
PendingIntent resultPendingIntent =
PendingIntent.getActivity(mCtx,ID_SMALL_NOTIFICATION,intent,
PendingIntent.FLAG_UPDATE_CURRENT
);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mCtx);
Notification notification = mBuilder.setSmallIcon(R.drawable.ic_logo_small).setTicker(title).setWhen(0)
.setAutoCancel(true)
.setContentIntent(resultPendingIntent)
.setContentTitle(title)
.setSmallIcon(R.drawable.ic_logo_small)
.setLargeIcon(getBitmapFromURL(url))
.setContentText(message)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setSound(defaultSoundUri)
.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
NotificationManager notificationManager = (NotificationManager) mCtx.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(ID_SMALL_NOTIFICATION, notification);
}
这里是我将图像从 url 转换为位图的地方
//The method will return Bitmap from an image URL
private 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;
}
基本上，如果我可以滑动图像。极好的。 不管怎样，一点帮助，这样我的通知程序就会像 Twitter 和 Instagram 一样简单而酷。 谢谢..
UPDATED: .setLargeIcon(BitmapFactory.decodeResource(mCtx.getResources(), R.drawable.ic_logo_small)) works but url doesn't.
但是我要设置的镜像是在线的(mysql)
最佳答案
如果你使用Glide，可以这样下载
GlideApp.with(this).asBitmap().skipMemoryCache(true).load(url).into(150, 150).get()
并且必须设置图片下载后的通知，
