回答1:

Android >= Honeycomb (self-explaining)

view.setX(x);
view.setY(y);

Android < Honeycomb Instead of directly setting it to the position you will tell "set it x pixels away from the left/top/right/bottom border".

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
lp.setMargins(x, y, 0, 0);

view.setLayoutParams(lp);
