Welcome to the JavaRanch, Anton!

Screen layout can be tricky, especially if you're trying to create a general-use program where people can be using devices whose screens are many different sizes and shapes.

For basic control layout, usually there's a layout manager that you can instruct on how to align components (left/right/center, top/middle/bottom).

If you're doing custom controls inside a Canvas, you'll have to do the work yourself. The center point is, of course w/2, h/2, where w and h are width and height of the Canvas object that you want to center the graphics in. And the top/left corner of the control would then be w/2 - bw/2, h/2 - bh/2, where "bw" and "bh" are the box width and box height of the control itself.

Frankly speaking the UI and controls offered by basic MIDP is very basic, to put it in a nice way.
For more control over component placements, layouts and a richer user experience, I would recommend using something like LWUIT
