I am using a Tabbar in my MainActivity. The tabbar has two tabs. When the tab will change, the menu will also change. So when I am in the "Recommendation" tab it will have the menu item "Refresh".

This is from my MainActivity class.

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    // TODO Auto-generated method stub

    if( tabHost.getCurrentTab() == 0 ){
        menu.clear();
        getMenuInflater().inflate(R.menu.watchlist_menu, menu);
    }else{
        //recommendations
        menu.clear();
        getMenuInflater().inflate(R.menu.recommendation_menu, menu);

    }

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

    switch( item.getItemId() )
    {
    case R.id.addItem:
        //
        startActivity( new Intent( this, AddActivity.class ) );
        return true;
    case R.id.refreshItem:
        //REFRESH FUNCTION SHOULD BE CALLED NOW
        return true;
    }

    return true;
}

The RecommendationActivity class has a function called refresh which I want to call when the refreshItem has been clicked. But how do I do that?

Create a class object and use its Function.

RecommendationActivity test = new RecommendationActivity();

test.refresh();
