                .build();


// Send the notification.
((NotificationManager)getSystemService(NOTIFICATION_SERVICE)).notify(NOTIFICATION, noti);

NotificationCompat

Compatibility

https://developer.android.com/guide/topics/ui/notifiers/notifications.html#Compatibility

하위 호환성을 위해 NotificationCompat 를 제공한다.

Example

NotificationCompat.InboxStyle style = new NotificationCompat.InboxStyle()
        .addLine(
                "M.Twain (Google+) Haiku is more than a cert...")
        .addLine("M.Twain Reminder")
        .addLine("M.Twain Lunch?")
        .addLine("M.Twain Revised Specs")
        .addLine("M.Twain ")
        .addLine(
                "Google Play Celebrate 25 billion apps with Goo..")
        .addLine(
                "Stack Exchange StackOverflow weekly Newsl...")
        .setBigContentTitle("6 new message")
        .setSummaryText("mtwain@android.com");

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.stat_sample)
        .setContentTitle(title)
        .setContentText(text)
        .setStyle(style);

Notification noti = mBuilder.build();
noti.flags |= Notification.FLAG_NO_CLEAR;

// Send the notification.
((NotificationManager)getSystemService(NOTIFICATION_SERVICE)).notify(NOTIFICATION, noti);

Action

Example

Intent intent = new Intent(this, NotificationReceiverActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);



NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.stat_sample)
        .setContentTitle("Content Title")
        .setContentText("Contetn Text")
        .addAction(R.drawable.stat_sample, "added action", pIntent)
        .setContentIntent(pIntent);

NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, mBuilder.build());

addAction()

addAction 을 하면 버튼이 추가된다. 이 버튼을 눌렀을 때의 동작을 set 해준다.

setContentIntent()

setContentIntent() 는 notification panel 에서 notification 을 click 했을 때 실행된다.

Customization

RemoteViews

자신이 원하는 모양으로 notification 을 보여주고 싶다면 RemoteViews 를 이용하자. 이 녀석을 new 해서 Notification 의 bigContentView 나 contentView 에 assign 해주면 된다.

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.stat_sample)
                .setContentTitle(title)
                .setContentText(text)
                .setContentIntent(contentIntent);

Notification noti = mBuilder.build();

RemoteViews expandedView = new RemoteViews(this.getPackageName(), R.layout.mp3player_notification);
expandedView.setOnClickPendingIntent(R.id.noti_image, contentIntent);
expandedView.setOnClickPendingIntent(R.id.noti_button_play, contentIntent);

noti.bigContentView = expandedView;

mBuilder.setContentIntent() 는 notification 전체에 대한 것이고,
setOnclickPendingIntent() 는 각각의 View 에 지정해 줄 수 있다.
