From the documentation,
Positioning your Toast
A standard toast notification appears near the bottom of the screen,
centered horizontally. You can change this position with the
setGravity(int, int, int)method. This accepts three parameters: a
Gravityconstant, anx-positionoffset, and ay-positionoffset.For example, if you decide that the toast should appear in the
top-left corner, you can set the gravity like this:toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0);If you want to nudge the position to the right, increase the value of
the second parameter. To nudge it down, increase the value of the last
parameter.
