Answer 1

Math.random()*width

where width is the maxValue of the range will give you a random x position, and you can do the same for the height of course

then you set your LinearLayout.LayoutParams

LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.setMargins(marginLeft, marginTop, 0, 0);
btn.setLayoutParams(params);

Voila, random position inside your layout
