我在收到每日通知时遇到了一些麻烦。没有出现警报通知
我的应用程序获取用户希望提醒某事的时间,时间和分钟。
然后我用AlarmManager
设立一个报警,此时重复,同时使用报警接收机,以创建通知。
我一直在尝试这个小时,但无法弄清楚我做错了什么。
我看了一堆其他SO问题,但没有人帮助过我。
我已经将用户的小时和分钟输入存储到日期对象get habitReminder中。
我createNotifications()
方法:
private void createNotifications() {
Log.i("Reminder at",""+habitReminder.getHours()+":"+habitReminder.getMinutes());
//Create the alarms/notifications for the user
Intent alarmIntent = new Intent(this, AlarmReceiver.class);
alarmIntent.putExtra("name", habitName);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
Log.i("createNotifications", "Alarm manager is created.");
//Set the timing of the reminder
Calendar calendar = Calendar.getInstance();
Calendar now = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, habitReminder.getHours());
calendar.set(Calendar.MINUTE, habitReminder.getMinutes());
calendar.set(Calendar.SECOND,0);
//Check to make sure time is after the current date.
if(calendar.before(now)){
calendar.add(Calendar.DATE, 1);
}
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
Log.i("createNotifications", "Alarm has been set for " +habitReminder.getHours()+":"+habitReminder.getMinutes() +" daily.");
}
我的报警接收器类:
public class AlarmReceiver extends BroadcastReceiver {
private static int id =0;
@Override
public void onReceive(Context context, Intent intent) {
String name = intent.getStringExtra("name");
String title = name + " Reminder!";
String message = "Your reminder to keep up your habit!";
long when = System.currentTimeMillis();
Intent in = new Intent(context, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(context,0,in,PendingIntent.FLAG_CANCEL_CURRENT);
NotificationManager nM = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification.Builder builder = new Notification.Builder(context)
.setContentIntent(contentIntent)
.setContentTitle(title)
.setContentText(message)
.setSmallIcon(R.mipmap.ic_launcher)
.setAutoCancel(true)
.setWhen(when);
Notification notification = builder.build();
nM.notify(id,notification);
id++;
}
}
而且我的Android manifest
:
<receiver android:name="com.closedbracket.trackit.AlarmReceiver" android:enabled="true">
</receiver>
任何帮助真的很感激。
你可以把'Log'里面你'的onReceive()'和检查,这是获得在设定的时间触发。 –
我有一个'setExact(AlarmManagaer ...)'的例子,它适用于我,所以它可以帮助你,[创建和设置AlarmManager](https://stackoverflow.com/a/44303234/5212904),它还解释了如何从另一个Activity中取消AlarmManager。然后,如果你一直到达接收者,那么你已经完成了一半,问题是'Notification'是否被正确实现。 – ArtiomLK
