For the button, in the xml layout, set android:clickable="true" and android:onClick="showMap", then in your first activity/class, it's like this:

public void showMap(View v) {
    Intent intent = new Intent(this, Map.class);
    startActivity(intent);
}

(Map.class being the class/name of your activity with the map. You need to adjust the name to your case.)
