I to want get and set margin of my LinearLayout from java. I do not want set like right,left, top, bottom etc. I just want set simple margin from all side. I know I can do it via XML but I do know how can I do it via java.

I have done via xml is like below

android:layout_margin="20dp"

Anyone can please suggest me how can I do it via java?

Solution

  • 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...
