HI,
(SetPosition for TextEdit doesn't seem to be in the docs.)
For Text it shows that the parent layout should be absolute,
and the parms are left, top, width, height, mode,
so yours should be at 0,0
I'd check the control, parent layout (and its parent ...)
for position, margins, padding, childmargins.
Setting background colours can clarify,
or Android Developer Settings has "show layout bounds"
