Maybe the title might be better, if someone knows a better one, please edit.

I've seen in many Java code notation that after a method we call another, here is an example.

Toast.makeText(text).setGravity(Gravity.TOP, 0, 0).setView(layout).show();

As you see after calling makeText on the return we call setGravity and so far.

How can I do this with my own classes? Do I have to do anything special?
