Android定位ImageView

Question

I am too tired to figure this out, so pls help.

I have an image view in a RelativeLayout and i need to position it during run-time at the top of the screen and in the middle. (so top-middle). I figured out how to place it at the top:

params = new RelativeLayout.LayoutParams(obWidth, obHeight);
params.addRule(RelativeLayout.ALIGN_PARENT_TOP);    

But now i only need to position in to the left a bit so it's in the middle of the screen.

BTW: I don't want to use margins.

Answer 1

也许这个吗？

params.addRule(RelativeLayout.CENTER_HORIZONTAL);
