Question

我正在开发一个活动策划应用程序，我目前正在开发一个将项目分配给访客的功能。分配项目后，会向客人推送通知，询问他是否可以携带所需物品。根据用户的输入，HTTP请求被发送回服务器，更新项目的状态（带来/不带）。

我有点坚持回应点击通知操作按钮，因为我不太明白它是如何工作的。我设法显示了操作按钮，但无法弄清楚如何响应点击它们。正如我在网上看到的那样，对通知操作按钮的响应由PendingIntent管理，我无法理解它是如何工作的，以及我如何根据点击的按钮使用它来发送HTTP请求。 / p>

我很乐意提供一些帮助和建议。

[这是发送给用户的通知示例。] [

这是通知用户的方法：

    private void notifyUser(Bundle data) {
    ...
    //Notification configuration.
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(...)
            .setLargeIcon(...)
            .setContentTitle(...)
            .setContentText(...)
            .setAutoCancel(...)
            .setSound(...);

        //Get the item data from the request sent to the GCM server.
        Item item = GsonFactory.getGson()
                .fromJson(data.getString("data"), Item.class);

        //This is the part that I do not understand...
        notificationBuilder
                .addAction(R.drawable.ic_close_black, "No", null)
                .addAction(R.drawable.ic_done_black, "Yes", null);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0, notificationBuilder.build());
}

先谢谢你了！

Answer 1

您必须为您的操作设置PendingIntent对象，以便当用户对通知按钮执行任何操作时特定意图被触发。可以为Activity, Broadcast Receiver or Service设置PendingIntent。如果要在用户单击通知按钮时显示活动，则可以使用 -

    Intent intent = new Intent(this, NotificationReceiverActivity.class);
    intent.putExtra(<key>, item ); //If you wan to send data also
    PendingIntent pIntent = PendingIntent.getActivity(this, <notification_id>, intent, 0); //<notification_id> may be any number

并将此意图设置为您的通知操作 -

notificationBuilder
                .addAction(R.drawable.ic_close_black, "No", pIntent)
                .addAction(R.drawable.ic_done_black, "Yes", pIntent);

我认为这可以帮到你

//使用Button

实现通知

private static void scheduleNotificationWithButton(Context context, String message) {

    int notifReCode = 1;

    //What happen when you will click on button
    Intent intent = new Intent(context, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 1, intent, PendingIntent.FLAG_ONE_SHOT);

    //Button
    NotificationCompat.Action action = new NotificationCompat.Action.Builder(R.mipmap.ic_launcher, "Go", pendingIntent).build();

    //Notification
    Notification notification = new NotificationCompat.Builder(context)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentText("Back to Application ?")
            .setContentTitle("Amazing news")
            .addAction(action) //add buton
            .build();

    //Send notification
    NotificationManager notificationManager = (NotificationManager)
            context.getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(1, notification);
}

Android通知操作按钮单击“侦听器”
