Refresh Menu with invalidate in Android

I am working on Android application in which I want to refresh my menu at run time. For example if in the starting my menu is like menu1.xml then after getting any result for example 'Yes' from the server I want to refresh it with menu2.xml.

I want to use invalidate function for this but I am not able to make my menu items to be refreshed. My code is given below:

@Override
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {

    if (showAcceptButton==true) {
        MenuInflater inflater = getSupportMenuInflater();
        inflater.inflate(R.menu.menu1, menu);
        return true;
    }if (Constants.showAcceptedButton = true) {
        MenuInflater inflater = getSupportMenuInflater();
        inflater.inflate(R.menu.menu2, menu);
        return true;
    }
    if(showNormalMenu==true){
        MenuInflater inflater = getSupportMenuInflater();
        inflater.inflate(R.menu.menu3, menu);
        return true;
    }
    return true;
}

At onCreate for the first time it loads the menu but on run time I want to load another menu items.

Once try as follows

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    // TODO Auto-generated method stub
    return super.onPrepareOptionsMenu(menu);
}

It will give existing menu object and you can add or delete menu items from it.

UPDATE:

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    // TODO Auto-generated method stub
    menu.clear();
    if (showAcceptButton==true) {
        MenuInflater inflater = getSupportMenuInflater();
        inflater.inflate(R.menu.menu1, menu);
        return true;
    }if (Constants.showAcceptedButton = true) {
        MenuInflater inflater = getSupportMenuInflater();
        inflater.inflate(R.menu.menu2, menu);
        return true;
    }
    if(showNormalMenu==true){
        MenuInflater inflater = getSupportMenuInflater();
        inflater.inflate(R.menu.menu3, menu);
        return true;
    }
    return super.onPrepareOptionsMenu(menu);
}

Hope this will helps you.
