Android - 如何将通知设置为将来的特定日期？

Question

编辑:已解决!曾经想要从某个特定日期开始设置通知(当某个活动开始时或按下按钮时？)阅读更多信息以了解如何:

 //Set a notification in 7 days
                Calendar sevendayalarm = Calendar.getInstance();

                sevendayalarm.add(Calendar.DATE, 7);

                Intent intent = new Intent(this, Receiver.class);
                PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 001, intent, 0);

                AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
                am.set(AlarmManager.RTC_WAKEUP, sevendayalarm.getTimeInMillis(), pendingIntent);

这是Receiver类的代码

public class Receiver extends Service {

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        Intent intent = new Intent(this, Test.class);
        long[] pattern = {0, 300, 0};
        PendingIntent pi = PendingIntent.getActivity(this, 01234, intent, 0);
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.depressiontest)
            .setContentTitle("Take Questionnaire")
            .setContentText("Take questionnaire for Duke Mood Study.")
            .setVibrate(pattern)
            .setAutoCancel(true);

        mBuilder.setContentIntent(pi);
        mBuilder.setDefaults(Notification.DEFAULT_SOUND);
        mBuilder.setAutoCancel(true);
        NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(01234, mBuilder.build());
    }
}

并且不要忘记在清单中添加以下权限!

<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
 <service android:name=".Receiver2" android:enabled="true">
        <intent-filter> <action android:name="NOTIFICATION_SERVICE" /></intent-filter>
    </service>

不要忘记给出以下清单权限

<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

您的广播接收器注册将是这样的

   <receiver android:name=".AlarmReceiver" >
         <intent-filter>
           <action android:name="NOTIFICATION_SERVICE" />
         </intent-filter>
     </receiver>
