I am assuming you are using a canvas to draw that stuff if so canvas has a method called getwidth() and also getheight()

what you can do is when you are drawing it to the canvas set the location point x and y coordinates as 

canvas.getWidth()/2
and canvas.getHeight()/2

something like this

canvas.drawBitmap(bitmap, canvas.getWidth()/2, canvas.getHeight()/2, null);

I hope you got the idea.

canvas.drawRect(left, top, right, bottom, paint)

use this function if you wanna draw a rectangle

Parameters: left The left side of the rectangle to be drawn

top The top side of the rectangle to be drawn

right The right side of the rectangle to be drawn

bottom The bottom side of the rectangle to be drawn

paint The paint used to draw the rect

Use the same logic in this method and you are golden ;)
