You can use following code to do so.

 LinearLayoutview ll= findViewById(R.id.linearLayout); //or however you need it
 LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) ll.getLayoutParams();

margins are accessible via

lp.leftMargin;
lp.rightMargin;
lp.topMargin;
lp.bottomMargin;

Now you can use the code 

 LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.MATCH_PARENT);
 params.setMargins(20,20,20,20);
 ll.setLayoutParams(params);

To set margin to the view you can use this code:

LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
     LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

layoutParams.setMargins(30, 20, 30, 0);

To get the margin of view use this code

View view = findViewById(...) //or however you need it
LayoutParams lp = (LayoutParams) view.getLayoutParams();
   // margins are accessible via

lp.leftMargin;
lp.rightMargin;
lp.topMargin;
lp.bottomMargin;

// perhaps ViewGroup.MarginLayoutParams will work for you. It's a base class for //other LayoutParams.

ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams) view.getLayoutParams();

Note: Sorry for using snippet... It will work like a charm...

Need use type of: MarginLayoutParams

Try this: 

MarginLayoutParams params = (MarginLayoutParams) vector8.getLayoutParams();
    params.width = 200; params.leftMargin = 100; params.topMargin = 200;

Code Example for MarginLayoutParams:
