Here you are :

Button button = new Button(this);
// weight = 1f , gravity = GridLayout.FILL 
GridLayout.LayoutParams param= new GridLayout.LayoutParams(GridLayout.spec(
            GridLayout.UNDEFINED,GridLayout.FILL,1f),
            GridLayout.spec(GridLayout.UNDEFINED,GridLayout.FILL,1f));
// Layout_height = 0 ,Layout_weight = 0
params.height =0;                                                                                                           
params.width = 0;
button.setLayoutParams(param);
