有我的代码显示内容到通知栏:

NotificationManager mNotificationManager = (NotificationManager)
                this.getSystemService(Context.NOTIFICATION_SERVICE);
 PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                new Intent(this, MyActivity.class).putExtra("package.notification", 123).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK),
                PendingIntent.FLAG_CANCEL_CURRENT);
        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.ic_launcher).setContentTitle("");
        // Set Big View style to see full content of the message
        NotificationCompat.BigTextStyle inboxStyle =
                new NotificationCompat.BigTextStyle();
        inboxStyle.setBuilder(mBuilder);
        inboxStyle.bigText("");
        inboxStyle.setBigContentTitle("");
        inboxStyle.setSummaryText("");
        // Moves the big view style object into the notification object.
        mBuilder.setStyle(inboxStyle);
        mBuilder.setContentText(msg);
        mBuilder.setDefaults(Notification.DEFAULT_ALL);
        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());


MyActivity.class中的onStart()

@Override
    protected void onStart() {
        super.onStart();
        if (getIntent().getIntExtra("package.notification", -1) == 123) {
            //check in here
        }
    }


问题是,当我单击通知栏中的通知时,MyActitvity活动总是新建的(如果存在MyActitvity活动,则重复活动)。

我要打开应用程序(这意味着MyActitvity活动处于活动状态),而不是新建MyActitvity。

仅在关闭应用程序时启动MyActitvity活动(MyActitvity未激活)

请给我指教

最佳答案

创建意图时,请使用此标志

Intent m_intent = new Intent(this, YourActivity.class);
m_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);


然后在待定意图中使用此意图
