Toast "setGravity" doesn't work on fragment

All the toasts I use in a fragment are shown in the same place. I tried to change the position using this code:

                val t = Toast.makeText(
                t.setGravity(Gravity.TOP, 0, 0)

but it doesn’t change anything at all. I’m not sure if I have to do anything else because this code is in a fragment, not in the main Activity. Thanks!
