android - 通知动作点击触发功能

Question

我正在用 Kotlin 编写一个应用程序，它应该显示一个带有操作按钮的通知。

我有一堂课。让我们称之为NotificationClass

此类通过为我创建通知fun createNotification()

这一切都很好。但是我想在通知中添加一个按钮，单击该按钮会触发我NotificationClass被调用的函数notificationActionClicked()。

有没有办法我可以做到这一点？

（通知类不是 android 服务。它只是一个实用程序类。）

您需要查看未决意图

 public void createNotification(View view) {
    // Prepare intent which is triggered if the
    // notification is selected
    Intent intent = new Intent(this, NotificationReceive.class);
    PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);

    // Build notification
    Notification noti = new Notification.Builder(this)
            .setContentTitle("New mail from " + "test@gmail.com")
            .setContentText("Subject").setSmallIcon(R.drawable.icon)
            .setContentIntent(pIntent)
            .addAction(R.drawable.icon, "Call", pIntent)
            .addAction(R.drawable.icon, "More", pIntent)
            .addAction(R.drawable.icon, "And more", pIntent).build();
    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    // hide the notification after its selected
    noti.flags |= Notification.FLAG_AUTO_CANCEL;

    notificationManager.notify(0, noti);

}
