時間敏感通知

-4

我正在嘗試構建一個簡單的應用程序，可以將通知發送給設備，但僅限於特定的日期/時間。我已經能夠得到通知部分的工作，但似乎不能得到解決的時間問題的一天&。有任何想法嗎？時間敏感通知

import android.app.Activity; 
import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 

public class NotificationsActivity extends Activity { 
    int notificationID = 1; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
    } 

    public void onClick(View view) { 
     displayNotification(); 
    } 

    protected void displayNotification() 
    { 

     Intent i = new Intent(this, NotificationView.class); 
     i.putExtra("notificationID", notificationID); 

     PendingIntent pendingIntent = 
      PendingIntent.getActivity(this, 0, i, 0); 

     NotificationManager nm = (NotificationManager) 
      getSystemService(NOTIFICATION_SERVICE); 

     Notification notif = new Notification(
      R.drawable.ic_launcher, 
      "Reminder: Meeting starts in 5 minutes", 
      System.currentTimeMillis()); 


     CharSequence from = "System Alarm"; 
     CharSequence message = "Meeting with customer at 3pm..."; 

     notif.setLatestEventInfo(this, from, message, pendingIntent); 


     notif.vibrate = new long[] { 100, 250, 100, 500}; 
     nm.notify(notificationID, notif);   
    } 

}
