Android :: Call Outside Function From Thread?

say for example I have this code in my activity:

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Thread cThread = new Thread(new Runner());
cThread.start();
}

private NotifyMe(){
//do something here
}


and this is my Runner class:

public class TCPClient implements Runnable {
public void run(){
//call NotifyMe() [THIS IS MY QUESTION]
}
}


I have a thread on my activity that runs the Runner Class. Once the thread start, I would like to call the NotifyMe() function that is located at the activity. Is this possible?
