  • Notification when item add to a ListView
    1 project | reddit.com/r/javahelp | 1 Nov 2021
    If you're just looking at making a service call on a regular interval and notifying the user when there's an actual change in data, you can also look into RxJava https://github.com/ReactiveX/RxJava. From here you can "subscribe" to your service call, and then every time you make your service call you can have it look for changes compared to the previous emission .distinctUntilChanged() and then only notify it's subscribers when it notices an actual change. From there you can trigger a local notification and push to a LiveData (assuming MVVM) or otherwise update the UI to match as well.

  • When consuming from a reactive stream is it more like a literal stream where items in the stream ay go by and not get consumed while you're busy, or is it more like a queue?

    In big words, kafka and rxJava are 2 different things, with kafka you transport data, produce and consume messages, then you can process them however you want. Rx java helps you write asynchronous code and it's no queue/topic related. You can read more here

    It's actually very easy to move things off the JavaFX thread. Here's a few options: - Plain old threads - ExecutorService (I would start here!) - RxJava (Look at suscribeOn and observerOn methods)
