Android - Programmatically specify height and width of new ScrollView

I'm new to Android and I'm working through a tutorial on programmatically creating a layout instead of doing it through the xml, I'm sorta stuck can someone advise please.

So I have a ScrollView then have added a LinearLayout into it, I want both to be a specific size - 480 x 800 (code below). I was able to set the size in the LinearLayout but I cannot get the ScrollView to also be that size but I can't find how to do it.

Is this possible, and can I therefore just specify the ScrollView dimensions and get the subsequent views to inherit that.

ScrollView home_scroll = new ScrollView(this);
LinearLayout home_linear = new LinearLayout(this);
home_linear.setOrientation(LinearLayout.VERTICAL);

home_scroll.addView(home_linear, new LinearLayout.LayoutParams(480, 800));

Any help would be greatly appreciated, thanks.

Simple way you can give dinamic width and height:- 

 LayoutParams layout = new LayoutParams(LayoutParams.WRAP_CONTENT,
                    LayoutParams.WRAP_CONTENT);
            layout.setMargins(screenWidth / 5, screenHeight - cardHeight - 30, 0, 0);
            tvConftxt.setLayoutParams(layout);

Try setting it up like this:

home_scroll.setLayoutParams(new ViewGroup.LayoutParams(480, 800));
home_scroll.addView(home_linear, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));

The linearlayout should now fill the scrollview.

Did you try doing something like

home_scroll.setLayoutParams(..,..);

you can find these here

setLayoutParams(ViewGroup.LayoutParams params) 
Set the layout parameters associated with this view.
