You can use this method inside your utils class to set height and width dynamically.

 public void setWidthAndHeight(Context context,RelativeLayout view,int width, int height) {
                width = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, width, context.getResources().getDisplayMetrics());//used to convert you width integer value same as dp
                height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, height, context.getResources().getDisplayMetrics());
               //note : if your layout is LinearLayout then use LinearLayout.LayoutParam
                view.setLayoutParams(new RelativeLayout.LayoutParams(width, height));
         }
