How do I subclass(?) Android Menu?

Hello,

This is more of a Java formatting question, but I was wondering how do I put my Menu Option Handler in another class and then refer to it elsewhere?

In other words, what do I need to pass to my subclass (is that even the right word to use?) and then how do I call that class in another class / activity?  Basically, this is a snippet of code that I would like to re-use in many classes / Activities, and if I modify it I would like it to change everywhere.

Attached is the code I would like to subclass(again, not sure if that is the right word).

Thanks!!!!
//handle menu 
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.loading_menu, menu);
        return true;
    }
    
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
    	
    	// Handle item selection
        switch (item.getItemId()) {
        case R.id.option1:
        	
        	//do something in here that is relevant to 
                //the class that was calling it.  i.e.
                //stopping a video from playing etc.
        	
            
            return true;
        default:
            return super.onOptionsItemSelected(item);
        }
        
    }

Can't you make those just static methods and refer to them with the class name.method from any place in your code?

What for_yan is suggesting is just creating a class, with only static methods. Example:


// Define a class and a static method on it:
public class MyMethods {

  public static void methodA(){
   //// Do stuff here
  };

}


/// To call that method anywhere, do this:

MyMethods.methodA();

You just need to add parameters that you will use to the method, thats it.
