android: changing option menu items programmatically

Question

Is it possible to change the option menu items programmatically? Can anyone provide me with an example please?

Also, I want to disable certain items, so that they do

You can do something simple like I did. Just change the text to what is needed when the menu item is touched. I needed to turn the sound off and on, plus the ability to perform an action by touching it. Here is my code:

    @Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
    case R.id.audioOn:
        audioOn = !audioOn;
        if (audioOn)
            item.setTitle("Audio Off");
        else
            item.setTitle("Audio On");
        return true;

    case R.id.touchOn:
        touchOn = !touchOn;
        if (touchOn)
            item.setTitle("Touch Off");
        else
            item.setTitle("Touch On");
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

audioOn and touchOn are booleans checked in other parts of the code. Hope this helps.
