I've read through the FAQ of Android Dev Guid (http://developer.android.com/guide/appendix/faq/commontasks.html#opennewscreen) but I'm not sure how can I open a new screen with additional parameters passed into it.

Let's say I'm going to open screen2, with a variable indicating the current user name so that I could greet the users. Is it possible?

Intent i; 
i = new Intent(this, screen2.class);  
//How to pass variable to screen2?
startActivity(i);
