Answer 1

by using the layoutparam in android, u can specify the position of your widget through the java code rather than specifying it in the xml file in android.

AbsoluteLayout.LayoutParams OBJ = new AbsoluteLayout.LayoutParams(35,35,408,160);
button.setLayoutParams(OBJ);

here-

AbsoluteLayout.LayoutParams(width,height,X-position,Y-position) 

is what i have specified as (35,35,408,160)
