android - 如何防止 Activity 重复午餐

Question

我的问题很简单，但是我找不到答案。任务是从通知到午餐 Activity ，但如果 Activity 正在运行，只需将数据传递给该 Activity 。我的应用程序只是一个接一个地进行午餐 Activity ，不适合我。

        Intent notificationIntent = new Intent(this, com.inyourcells.finelife.MainDesk.class);
        notificationIntent.putExtra(MainDesk.CONFIRM_INDEX_PARAM, confirmIndex);
        pIntent = PendingIntent.getActivity(this, id, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);


        builder = new Notification.Builder(getApplicationContext())
                .setContentTitle(getString(R.string.new_operation))
                .setContentText(getString(R.string.press_new_operation)+sum+MainDesk.CUR)
                .setTicker(getString(R.string.ticker_new_operation)).setWhen(System.currentTimeMillis())
                .setContentIntent(pIntent)
                .setDefaults(Notification.DEFAULT_SOUND|Notification.DEFAULT_VIBRATE|Notification.DEFAULT_LIGHTS).setAutoCancel(true)
                .setSmallIcon(R.drawable.accounts_icon);
    }

为 list 中的 Activity 尝试这个:

android:launchMode="singleTop"
