活动不显示

Question

我创建的通过点击一个通知的活动发起创建了一个通知，广播reciever，该活动推出，但我不能看见它，我使用下面的代码：

private NotificationManager notificationManager; 
    @Override 
public void onReceive(Context context, Intent intent) { 
    if (notificationManager == null) { 
     notificationManager = (NotificationManager) context 
       .getSystemService(Context.NOTIFICATION_SERVICE); 
    } 
    NotificationCompat.Builder builder = new NotificationCompat.Builder(context) 
      .setTicker("Its Ticker") 
      .setSmallIcon(R.drawable.ic_launcher) 
      .setContentTitle("Notification Title") 
      .setContentText("Its Content") 
      .setAutoCancel(true) 
      .setContentIntent(PendingIntent.getActivity(context,0,new Intent(context, NotificationDialog.class).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK),0)); 
    notificationManager.notify("interstitial_tag", 0, builder.getNotification()); 

} 

注意：NotificationDialog.java是我的活动，此活动正在运行，因为我调试但未查看。尝试几个小时，但无法找到任何答案，任何建议将不胜感激。

使用FLAG_ACTIVITY_CLEAR_TOP，而不是FLAG_ACTIVITY_CLEAR_TASK

private NotificationManager notificationManager; 
    @Override 
public void onReceive(Context context, Intent intent) { 
    if (notificationManager == null) { 
     notificationManager = (NotificationManager) context 
       .getSystemService(Context.NOTIFICATION_SERVICE); 
    } 
    NotificationCompat.Builder builder = new NotificationCompat.Builder(context) 
      .setTicker("Its Ticker") 
      .setSmallIcon(R.drawable.ic_launcher) 
      .setContentTitle("Notification Title") 
      .setContentText("Its Content") 
      .setAutoCancel(true) 
      .setContentIntent(PendingIntent.getActivity(context,0,new Intent(context, NotificationDialog.class).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP),0)); 
    notificationManager.notify("interstitial_tag", 0, builder.getNotification()); 

}
