创建包含到期日期的Android通知

Question

我想在Android中创建一个具有过期日期的通知,这意味着在某个特定日期,如果它没有打开,它将被自动销毁或删除.这可能吗？有人知道怎么做吗？

谢谢你的帮助.

如果您有通知ID,则可以通过调用删除自己的应用程序通知NotificationManager.cancel.要实现过期,您可以设置警报AlarmManager以唤醒BroadcastReceiver只会取消通知的警报.(如果通知不再存在,则取消的呼叫将不执行任何操作.)

// post notification
notificationManager.notify(id, notification);

// set up alarm
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, MyBroadcastReceiver.class);
intent.setAction("com.your.package.action.CANCEL_NOTIFICATION");
intent.putExtra("notification_id", id);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

// note: starting with KitKat, use setExact if you need exact timing
alarmManager.set(..., pi);

在你的BroadcastRecevier中......

@Override
public void onReceive(Context context, Intent intent) {
    final String action = intent.getAction();
    if ("com.your.package.action.CANCEL_NOTIFICATION".equals(action)) {
        int id = intent.getIntExtra("notification_id", -1);
        if (id != -1) {
            NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManager.cancel(id);
        }
    }
}
