我试图创建像 Gmail 应用程序下面的图片所示的多行通知(将 5 条通知分组为一条通知)。
我尝试了各种示例,但似乎只能创建单个通知。
![enter image description here](https://istack.dev59.com/SAbuS.webp)
public void createSingleNotification(String title, String messageText, String tickerttext) {
int icon = R.drawable.notification_icon; // icon from resources
CharSequence tickerText = tickerttext; // ticker-text
long when = System.currentTimeMillis(); // notification time
Context context = getApplicationContext(); // application Context
CharSequence contentTitle = title; // expanded message title
CharSequence contentText = messageText; // expanded message text
Intent notificationIntent = new Intent(this, MainActivity.class);
Bundle xtra = new Bundle();
xtra.putString("title", title);
xtra.putString("message", messageText);
notificationIntent.putExtras(xtra);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
notificationIntent, PendingIntent.FLAG_ONE_SHOT
+ PendingIntent.FLAG_UPDATE_CURRENT);
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
Notification notification = new Notification(icon, tickerText, when);
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.defaults |= Notification.DEFAULT_SOUND;
notification.defaults |= Notification.FLAG_AUTO_CANCEL;
notification.flags = Notification.DEFAULT_LIGHTS
| Notification.FLAG_AUTO_CANCEL;
final int HELLO_ID = 0;
mNotificationManager.notify(HELLO_ID, notification);
}
我不确定如何创建一个可以添加行的通知组。
