问题描述
当我设置的通知从一个datepicker和TimePicker选择特定的日期和时间，该通知出现在正确的时间，但之后，我取消它，它一段时间后再次出现。结果
我曾尝试 setAutoCancel（真）和 Notification.FLAG_AUTO_CANCEL ，但他们似乎没有工作。
这里是code-片段在那里我设置报警
如果（item.getTitle（）。等于（添加提醒））

Log.d（提醒，显示时间选择器从决定该案进入）;

解决方案
这可能是因为报警。 通知如果调用本身不能添加一个更多的时间 setAutoCancel（真）。
您可以尝试
a.cancel（发件人） AlarmReceiver 的onReceive C>你的事。
你将不得不重新创建sender对象取消它。
When I set a Notification on a particular date and time chosen from a DatePicker and a TimePicker, The notification appears on the correct time but after I cancel it, it reappears after some time.
I have tried setAutoCancel(true) and Notification.FLAG_AUTO_CANCEL but they don't seem to work.
here is the code-snippet where I'm setting alarm
if(item.getTitle().equals("Add Reminder"))
{
Log.d("REMINDER", "Show Time Picker Entered from Decided Case");
final Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.date_time_layout);
dialog.setTitle("Choose Date and Time");
dialog.show();
Button ok = (Button) dialog.findViewById(R.id.alarm_set);
ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
DatePicker dp = (DatePicker) dialog.findViewById(R.id.datePicker1);
TimePicker tp = (TimePicker)dialog.findViewById(R.id.timePicker1);
Calendar cal = Calendar.getInstance(); //for using this you need to import java.util.Calendar;
// add minutes to the calendar object
cal.set(Calendar.MONTH, dp.getMonth());
cal.set(Calendar.YEAR, dp.getYear());
cal.set(Calendar.DAY_OF_MONTH, dp.getDayOfMonth());
cal.set(Calendar.HOUR_OF_DAY, tp.getCurrentHour());
cal.set(Calendar.MINUTE, tp.getCurrentMinute());
//cal.add(Calendar.MINUTE, 1);
//cal.setTimeInMillis(System.currentTimeMillis());
// cal.add(Calendar.SECOND, 10);
Intent alarmintent = new Intent(getApplicationContext(), AlarmReceiver.class);
PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(), 0,
alarmintent,0);
int HELLO_ID=1;
// Get the AlarmManager service
HELLO_ID++;
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);
Log.d("Alarm Set","day = "+dp.getDayOfMonth()+" month = "+(dp.getMonth()+1)+" year = "+dp.getYear()+" hours "+tp.getCurrentHour()+" minutes = "+tp.getCurrentMinute());
dialog.dismiss();
}
});
}
AlarmReciever.java
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// When our Alaram time is triggered , this method will be excuted (onReceive)
// We're invoking a service in this method which shows Notification to the User
Intent myIntent = new Intent(context, NotificationService.class);
context.startService(myIntent);
}
};
NotificationService.java
public class NotificationService extends Service {
private NotificationManager mManager;
Notification notification;
private static int NOTIFICATION_ID = 1;
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
super.onCreate();
}
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
// Getting Notification Service
mManager = (NotificationManager) this.getApplicationContext()
.getSystemService(
this.getApplicationContext().NOTIFICATION_SERVICE);
/*
* When the user taps the notification we have to show the Home Screen
* of our App, this job can be done with the help of the following
* Intent.
*/
Intent intent1 = new Intent(this.getApplicationContext(), DecidedCase.class);
PendingIntent pendingNotificationIntent = PendingIntent.getActivity(
this.getApplicationContext(),NOTIFICATION_ID, intent1,
PendingIntent.FLAG_UPDATE_CURRENT);
//notification = new Notification(R.drawable.ic_launcher,
// "Trying out Alarm", System.currentTimeMillis());
notification = new NotificationCompat.Builder(this.getApplicationContext())
.setContentTitle("ScheduLAWyer")
.setContentText("You've got a notification")
.setContentIntent(pendingNotificationIntent)
.setSmallIcon(R.drawable.ic_launcher)
.setAutoCancel(true)
.setPriority(8)
.setTicker("A case has to be viewed").build();
//.addAction(R.drawable.ic_launcher,"Launch app",pendingNotificationIntent)
//.addAction(R.drawable.ic_launcher, "Cancel",pendingNotificationIntent).build();
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.setLatestEventInfo(this.getApplicationContext(),
"sudduLAWyer", "Trying out Alarm Manager",
pendingNotificationIntent);*/
//notification.flags = Notification.FLAG_INSISTENT;
notification.flags |= Notification.FLAG_AUTO_CANCEL | Notification.FLAG_INSISTENT | Notification.FLAG_SHOW_LIGHTS;
notification.defaults |= Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE;
//notification.defaults |= Notification.DEFAULT_VIBRATE;
//notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notification.ledARGB = 0xFFFFA500;
notification.ledOnMS = 800;
notification.ledOffMS = 1000;
mManager.notify(NOTIFICATION_ID++, notification);
Log.d("NOTIFICATION","Notficiation Set");
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
mManager.cancel(0);
}
}
解决方案
It is probably because of the alarm. Notification itself cannot add it one more time if you call setAutoCancel(true).
You can try
a.cancel(sender) in onReceive of AlarmReceiver of yours.
You will have to recreate that sender object to cancel it.
