How to show Toast messages from a thread in another class

Question

I'm developing an app and I need to show a Toast message from a Thread that runs in another class. I Read about runOnUiThread but it doesn't works.. In main activty there is a call to another java class and here there is the connection to a webserver and I handle Http's messages from the server. Here, if I got 204 messages I need to show a toast. How can I implement runOnUiThread?

Thanks

Pass your activity's reference to that worker class and call the runOnUiThread like this

 activity.runOnUiThread(new Runnable() {
    public void run() {
        Toast.makeText(activity, "Your Message here", Toast.LENGTH_SHORT).show();
    }
});
