即使用户关闭了应用程序,我也希望向用户显示通知。但我没有得到未来时间的通知,就像我想在特定时间每天通知用户一样。
**Here what i have tried**
> Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
Intent myIntent = new Intent(MainActivity.this, MyReceiver.class);
if(hour == 18) {
pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, myIntent,0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
}
** Here is my service class**
public class MyAlarmService extends Service
{
private NotificationManager mManager;
@Override
public IBinder onBind(Intent arg0)
{
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate()
{
// TODO Auto-generated method stub
super.onCreate();
}
@SuppressWarnings("static-access")
@Override
public void onStart(Intent intent, int startId)
{
super.onStart(intent, startId);
mManager = (NotificationManager) this.getApplicationContext().getSystemService(this.getApplicationContext().NOTIFICATION_SERVICE);
Intent intent1 = new Intent(this.getApplicationContext(),MainActivity.class);
Notification notification = new Notification(R.drawable.ic_launcher,"This is a test message!", System.currentTimeMillis());
intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP| Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingNotificationIntent = PendingIntent.getActivity( this.getApplicationContext(),0, intent1,PendingIntent.FLAG_UPDATE_CURRENT);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.setLatestEventInfo(this.getApplicationContext(), "AlarmManagerDemo", "This is a test message!", pendingNotificationIntent);
mManager.notify(0, notification);
}
@Override
public void onDestroy()
{
// TODO Auto-generated method stub
super.onDestroy();
}
答案 0 :(得分:2)
您可以使用AlarmManager设置重复。
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000*10, pendingIntent);

你要停止闹钟
public void stopAlarmManager()
{
if(alarmManager != null)
alarmManager.cancel(pendingIntent);
}

记住不要忘记在清单文件中注册Receiver
<receiver android:name=".AlarmBroadcastReceiver" >
</receiver>

这会对你有帮助。
