You should define your problem in more exact terms. Can you provide an SSCCE that demonstrates what you have, and explain more regarding what you want?

First off all it's not a good idea setting layout programmatically.

Button button = new Button(this);
bt.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams .WRAP_CONTENT));
