Android reminder!
开发者_C百科I would like to ask which service and how to use to make reminder in android... Let's say: after 10 minutes from now show me notification in notification bar...
Thanks for your answer
Obviously you should use AlarmManager in order to setup something to be executed in given PERIOD.
AlarmManager mgr = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(context, OnAlarmReceiver.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
mgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime(), PERIOD, pi);
where the PERIOD is your time to something that should be executed in OnAlarmReceiver. And then, just implement method in
@Override
public void onReceive(Context context, Intent intent) {
NotificationManager nm = (NotificationManager);
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification();
notification.tickerText = "10 Minutes past";
nm.notify(0, notification);
}
Enjoy.
You should use AlarmManager
. With it you can schedule an intent to be delivered. Create a BroadcastReceiver
to get it and show the notification.
Somethink like this i guess, you start an runnable after 10min and open an notification in the runnable's code.
Runnable reminder = new Runnable()
{
public void run()
{
int NOTIFICATION_ID = 1324;
NotificationManager notifManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification note = new Notification(R.drawable.icon, "message", System.currentTimeMillis());
// Add and AUTO_CANCEL flag to the notification,
// this automatically removes the notification when the user presses it
note.flags |= Notification.FLAG_AUTO_CANCEL;
PendingIntent i = PendingIntent.getActivity(this, 0, new Intent(this, ActivityToOpen.class), 0);
note.setLatestEventInfo(this, "message", title, i);
notifManager.notify(NOTIFICATION_ID, note);
}
};
Handler handler = new Handler();
handler.postDelayed(reminder, 600000);
