Question

In my application i created a login session.
I’ve got an ActionBar with two icon, “home” and “login”. I want to replace “login” with a string (Welcome Dude!, for example) after a successfull login.
I waked this way: if there’s no user logged, an action bar is shown, with HOME and ICON items. When a user is logged, another action bar is shown. In this second action bar i’d like to have HOME item and a welcome message.

Is that possible?

I thought also to create an item and set its text when the login is successfull, but i can’t do that.

Can anyone help me?

You can override onPrepareOptionsMenu(). It works with ActionBarSherlock library:

@Override
public boolean onPrepareOptionsMenu(Menu menu) 
{
    if(userIsLogged){
        getSupportMenuInflater().inflate(R.menu.menu_with_hello_string, menu);
    }
    else {
        getSupportMenuInflater().inflate(R.menu.menu_with_login_button, menu);
    }
    return super.onPrepareOptionsMenu(menu);
}

You just need to call invalidateOptionsMenu(); when the user logs in.

Hope that helps.
