通过通知向pendingent发送不同的参数

putExtra .

每次通过通知栏启动的活动启动时,它都会销毁尚未启动的活动(仍显示在通知栏上的活动)。

如何使用自己的参数保存所有通知?

if (messagesManager == null)
{
    messagesManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
}

notification = new Notification(R.drawable.icon, message, System.currentTimeMillis());

// for launch activity
Intent intent = new Intent(context, DialogActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.putExtra("fileName", fileName); //- this is where i put my extra's!!
intent.putExtra("onSdcard", onSdcard);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

notification.setLatestEventInfo(context, "DownloadManager", message, contentIntent);
notification.flags = notification.FLAG_AUTO_CANCEL;
int noticeId = generateNotificationId(requestId);
messagesManager.notify(noticeId, notification);

现在是对话活动:

protected void onCreate(Bundle savedInstanceState)
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    Intent i = getIntent();
    boolean onSdcard = i.getBooleanExtra("onSdcard", true);
    String fileName = i.getStringExtra("fileName");
    ...
}

我试图使用这个技巧,因为它是写在另一篇文章在这里,但它没有工作。

intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
