正在 pendingIntent 从堆栈中移除启动器 activity

Question

我有一些问题。当我的应用程序不在后台（从最近删除）时，一切正常。但是当我的应用程序是最近的，然后我通过通知挂起意图打开 "ResponseActivity" 时，在 "ResponseActivity" 的后退单击我进入我的 MainActivity（启动器 activity）。我添加了 FLAG_ACTIVITY_NEW_TASK 但它似乎没有添加。

    Intent intent = new Intent(this, ResponseActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP   | Intent.FLAG_ACTIVITY_NEW_TASK);

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
            .setSmallIcon(R.drawable.ic_launcher_background)
            .addAction(0, "Other", pendingIntent) 
            .setLargeIcon(getCircleBitmap(bitmap))
            .setContentTitle(userDB.getName())
            .setContentText(smallText)
            .setAutoCancel(true)
            .setDefaults(Notification.DEFAULT_ALL)
            .setColor(getResources().getColor(R.color.colorPrimary))
            .setPriority(NotificationCompat.PRIORITY_DEFAULT);


    NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel channel = mNotificationManager.getNotificationChannel(NOTIFICATION_CHANNEL_ID);

        channel.setDescription("");
        channel.enableLights(true);
        channel.setLightColor(Color.RED);
        channel.enableVibration(true);

        mNotificationManager.createNotificationChannel(channel);
    }

    mNotificationManager.notify(1000, mBuilder.build());

如果您想确保在 select 通知时只有 ResponseActivity 在堆栈中，您可以这样做：

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);

而不是：

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
