You can use putExtra and getStringExtra with your Intent to pass String parameters to a new Activity.

In Activity A:

Intent intent = new Intent(this, B.class);
intent.putExtra("firstName", firstName);
intent.putExtra("lastName", lastName);
startActivity(intent);

In Activity B:

@Override
protected void onCreate(Bundle savedInstanceState) {
    String firstName = getIntent().getStringExtra("firstName");
    String lastName = getIntent().getStringExtra("lastName");
        ....
}

There are also getFooExtra and putExtra methods for all of the other basic datatypes.
