Sorry if this is too basic. I created a new class that extends Button:

public class MyButton extends Button {

private Context ctx;

public MyButton(Context context) {
    super(context);
    ctx = context;
}

private void click() {
    // DO WHAT I NEED (FOR EXAMPLE CHANGE BACKGROUND)
}   
}

How can make it possible that, when I setOnClickListener() from another class where I instantiated this object, the click() method is called automatically? Thanks.
